What Hurdles Will Amazon Prime Air Need to Overcome?

By Victoria Greene – @vickyecommerce

At the beginning of December, it will have been 5 years since Amazon kingpin Jeff Bezos announced plans for Amazon Prime Air. Initially mocked in popular culture, everyone soon realized that it’s precisely the sort of thing Amazon could and would do, and settled back to see where the chips would fall.

Today, the dream has yet to come to fruition — and other companies have followed suit in betting big on drone delivery hardware and systems — yet the smart money remains on Amazon being the big beneficiary of this automated revolution, especially since it has put so much time and money into getting it right.

However, by the time Amazon’s Prime Air drone fleet goes live (whether in 2019 or much later), it will need to have overcome some major hurdles that currently face all drone delivery systems. What hurdles are those? Let’s go through them.

Legally using airspace

The Federal Aviation Authority (FAA) is still in the early stages of figuring out how it’s going to handle approval for drone fleets, and thus far its regulations have focussed on manned personal drones. To this point its limitations have been based on maintaining the privacy of citizens and protecting airspace required for other things (such as planes).

Add Prime Air to the mix and you get a tremendously complex situation. Who will be monitoring the drones, and how? How will Amazon avoid drones getting in the way of planes, particularly in busy urban areas? Presumably there will need to be an overarching cross-system network to keep everything neatly synched, but that will increase the complexity.

And in the event of something going wrong, who will ultimately hold responsibility? How will anyone know for sure? If a Prime Air drone crashes into a drone from a rival shipping company (and self-destructs, apparently), each company might claim the fault must have been with the other. It’s certainly understandable that authorities would want to take a lot of time to figure out how everything is going to work before opening the floodgates.

Public distaste for automated transport

On the topic of responsibility, there remains a lot of antipathy towards automated transport systems and smart technology in general. For better or worse, people like to feel that cars, buses, bikes, planes, trains, and, yes, drones are manually controlled. When something goes wrong, there’s someone to blame — someone to hate (and to sue if needed).

When you take the manual control away — or move it back several levels to a position of limited oversight — you attract pushback. Not only do people not want to entrust shadowy automated systems with important tasks (and even their fates), but they also don’t like the consequences in the world of employment.

Just think about what will happen if Prime Air becomes a roaring success and the drone delivery system becomes an ecommerce staple. Heavy things will still need to be shipped by road, naturally, but that will be cold comfort to the many delivery drivers likely to be pushed elsewhere to work for smaller and cheaper companies that can’t afford or justify drones.

The world of technology may have greatly expanded the business opportunities for entrepreneurial types (with a laptop and an internet connection you can take courses, start a store and sell your small business for a tidy profit), but not everyone wants to learn tech. They want to preserve their careers, and drones will prevent them from doing so. The antipathy will eventually fade, but there will be many bitter pills to swallow first.

Keeping communications secure

Amazon Prime Air will invariably have manual oversight (if only to keep investors happy and placate the public), but secure communication will be essential regardless. The more drones are in the air at any time, the more carefully they will need to be arranged to avoid clashes. But the networking demands go past that.

When you establish a high-profile network of any kind, you inevitably attract attempts to hack it: to shut it down, draw data from it, or alter its protocols somehow. Each drone will need to be able to send and receive data to and from the main Amazon system, so people will no doubt attempt to seize drones and analyze them to find a way to break into it.

Could people find ways to locate drones holding expensive items and reroute them? It’s plausible. Very unlikely, I’d say, since I don’t think Amazon would go live without being very confident in its ability to keep its software secure, but this is certainly an obstacle that will need to be completely overcome before getting anywhere.

Establishing enough fulfilment centers

Drone fleets (using today’s technology, at least) will offer incredible flexibility and convenience at the cost of range. When Prime Air was announced, it was noted that a drone delivery must be within a 10-mile radius of an Amazon fulfilment center, which means that Amazon will need a lot more fulfilment centers if it hopes to ever make Prime Air a default delivery option.

And even if it manages to get that many fulfilment centers set up, how will stock levels be handled? The level of complexity will go through the roof. Might we see complex chains of drone deliveries, with one transporting an item to another fulfilment center to be picked up and carried along by another drone? Or will Amazon simply rely on demand prediction models and keep Prime Air as an occasional delivery method?

I don’t anticipate it replacing next-day (or even same-day) standard delivery, but I can certainly see it becoming a very common option. It won’t happen until Amazon gets the infrastructure in place, though, so let’s see how things proceed.

Amazon Prime Air has a lot of promise, but there are many challenges for it to pass before any of that promise can be fulfilled. Thankfully, once it does pass those challenges, there will be a convenient fulfilment system available to make it happen.

DJI Osmo pocket – the vlogging camera you’ve been waiting for

By Paul Archer, Dronesgator.com

A new recent release from DJI makes its way in 2019 with what seems to be a very unique approach to personal consumer cameras.
DJI has quite some history when it comes to gimbal stabilized cameras, both for their drones and for their Osmo line and this makes them quite the expert in the domain.

Osmo Pocket
Osmo Pocket

I know that at a first glance this device didn’t seem like it had much potential. However, the moment I took it into my own hands I’ve been quite amazed by what it can do.

It’s called the Osmo pocket and I’m completely amazed by how far technology has moved in the recent years. Having such a small yet capable device is something that no one would have dreamt of just a year ago.

Is it a vlogging camera or an action cam?

It has been released some time after the latest gopro hero 7 and people, including me, have compared the two on equal footing because of their bragging about stabilization.

However, the Osmo is more than an action cam, it definitely isn’t as sturdy as the latest GoPro hero, but It holds its own with some very good materials and a very good build.

GoPro vs Osmo Pocket

However, the osmo does have the considerable advantage of permanent 3 axis gimbal stabilization, which means it isn’t limited with electronic stabilization that can fail in poor lighting conditions.

Why is the Osmo pocket a great contender for being one of the top vlogging cameras in the future?

  • Super portable (no need to carry a big camera around you all the time)
  • Incredibly well stabilized video
  • Records in 4k 60p and even slow motion up to 120fps
  • Has the option to easily change the camera orientation towards you or in front by the press of a button
  • Has automatic tracking options
  • Good close up focus
  • More professional, cinematic look thanks to the shorter field of view compared to the fisheye of a goopro for example.

How does it face off against a gopro?

They’re not exactly competing in the same category as I mentioned before, but the new osmo pocket does actually take away some of the market from any action camera.

For more casual recordings, vlogging and whatever scenario that requires a tiny stabilized camera, besides extreme sports.

GoPro Hero7 vs Panasonic G7 vs Osmo Pocket
GoPro Hero7 vs Panasonic G7 vs Osmo Pocket

Bellow there’s my video comparison to the GoPro Hero 7 black where I also tested the stability on rough terrain, different resolutions side by side, slow motion and more!

What are some specs and is the price worth it?

When it comes to the price, the DJI Osmo pocket is just under the price of the latest Gopro. Now, you decide if it’s justified for your own needs to spend $350 on a multifunctional camera like this.

However, I could argue that if this manages to replace an expensive DSLR camera for video that you used to barely carry around and shoot shaky videos with… it’s totally worth it.

And the quality is up there, with a nice field of view and blurred background when in selfie mode.

Here are some of the more important specs I felt like people would need to know:

  • 12mp camera
  • 1/2.3-inch sensor
  • 80 degree FOV
  • 100Mbits
  • F/2.0 apperture
  • 4k 60fps
  • 1080p 120p
  • Supports micro sd card of up to 256gb
  • Comes with multiple accessories

How about the accessories?

Well, DJI is already selling quite a lot of those on their site and they seem to be quite useful, even though they have a long way to catch GOPro from behind.

The overall package is super tiny, but if you do indeed decide to attach the phone, maybe because you find the screen too small, it’s going to be less easy to hold in only one hand.

So if you were looking for a new camera and a gimbal for it, the new Osmo pocket might make your life better with a more complete, smaller and quite capable package for the price of an action camera.

Next-Gen Fighters’ Drone Wingmen

Breakingdefense.com reported that the US Air Force hopes to develop and field autonomous combat drones that would augment piloted fighters “in the mid to late 2020s,” Andrew Hunter, the Air Force’s top acquisition official, said in August.
Over the past year, Air Force Secretary Frank Kendall has made it clear that “Loyal Wingman”-style combat drones, partnered with stealth fighters like the F-35 or its yet-to-be-revealed sixth-generation fighter, will be a key element of the service’s future tactical aircraft inventory.

Kendall’s vision is that pilots of aircraft such as the sixth-gen Next Generation Air Dominance fighter, F-35 and F-22 would be able to command one to five drones, “calling plays” that the drones would then be able to accomplish autonomously — although the decision to use a weapon will still fall to human operators.

As the Air Force delineates the technologies that will make up its Next Generation Air Dominance family of systems — which is known to include a suite of Collaborative Combat Aircraft (CCA) drones along with a manned, sixth generation fighter and the AIM-260 Joint Advanced Tactical Missile currently under development — its leadership is also drilling down on a strategy to rapidly develop and field CCA drones “in the mid to late 2020s,” Andrew Hunter, the Air Force’s top acquisition official, said in August.

Virtual Sims Help Design Drone Controls

One aspect of UAV design is the control system, and virtual simulations are being used to design drone control systems. Aviationtoday.com reported that this summer, Boeing conducted a digital simulation of an open autonomy architecture to have manned Navy aircraft control MQ-25A Stingray unmanned carrier-based tankers. Boeing virtually demonstrated how a Northrop Grumman [NOC] E-2D Advanced Hawkeye command and control aircraft, Boeing P-8A Poseidon maritime patrol and reconnaissance aircraft, and F/A-18E/F Block III Super Hornet fighters could task four virtual autonomous MQ-25s to conduct tanking and intelligence, surveillance and reconnaissance (ISR) missions. Notably, the demonstration showed how aircraft can use the architecture to task MQ-25s for tanking and ISR missions “without traditional communications with the ship-based ground control station. …In the most recent tests, Boeing also highlighted that Aurora created and demonstrated a software boundary called a prototype platform abstraction layer that separates out the MQ-25’s flight safety and flight critical components from mission software and sensor hardware.” Photos courtesy of Boeing.

10 Effective ways to make your drone footage more natural

By John O. Brooks

Drone Footage have become famous and popular on the internet nowadays. It’s very normal to see the footage from all over the world whilst more and more people entering the world of drones. Drones are affordable and accessible these days and nearly anyone can be able to manage to fly one.

However, flying a drone is one thing while shooting good quality footage with it is completely a different thing.

To impress your viewers with your Drone Shots, your shooting should be on a top level. After watching your Drone Footage, it becomes clear in your viewer’s eyes in seconds whether you actually know what you are doing or not. There is no doubt that using a Drone needs enough practice and some skills and planning to
make the best out of it. The more you practice flying your Drone, the more you become better on it.
So, here I am sharing with you a bunch of tips that will hopefully help you to make your drone footage more natural and realistic.

1. Plan your entire shot

You should always plan your shot before starting to fly. What do you want to get from the video, or which angle you are going to capture, everything should be planned. I know it is very tough work to plan everything from the ground as you don’t get the whole picture from the above but trust me, at least trying to have some ideas about your path and lines helps you to get better footage. Picture your
expected movements in your head and start practicing them. It’s impossible to get that flawless and perfect view, but by practicing them you can have a nice, smooth and steady result in the end.

2. Slow and steady wins the race

The best footage comes then when you start shooting by flying slow. It allows you to capture the footage vividly. By flying slow, you’re giving some time to your viewer to understand the whole scenario and dig into it. It creates a cinematic feeling in your video which should be your main target.

3. Fly low

As an aerial videographer, you should always keep in mind that flying high endangers your drone and your footage, especially when the wind speed is high.
Flying high is good but it doesn’t mean that you should do it all the time. It’s very risky if the wind is around 15-20 mph, it could probably damage your drone. Thus, to capture some nice and steady footage, I recommend flying lower, where the wind speed is not that high, the drone will be more controllable.

4. Fly backward

Flying backward is one of the cool techniques to make your drone footage more natural and cinematic. When you move forward, you’re focusing only on one specific detail. But when you’re flying backward, it reveals more details in your footage such as
trees, lakes, buildings, hills, people, etc.
Though to some of you, flying backward might seem difficult, which is totally okay. You can use the speed duration tool in your video editor to reverse your footage.

5. Avoid rough movements

You can’t just move your camera here and there to bring the cinematic feeling to your footage. Jerky movements are really disturbing to the viewers and it kill the liveliness of the footage. They make the video look robotic. I recommend you not to switch your speed and angles constantly but rather keep your position steady and use controlled and smooth movements as much as possible. By doing so, the video will feel natural and cinematic.

6. Don’t rush to the main object

It is a common rookie mistake to start shooting your main object at first sight. You must always keep a storyline in your footage. Add some contexts first, it brings excitement to the viewer’s eyes. Build up your shot, and slowly fly over your object and reveal it.

7. Golden hour light

The term Golden Hour refers to the period before the sunset and after the sunrise, when the sunlight is warmer and softer than the usual. Using the camera in the afternoon can damage the exposure because of the bright harsh light of the sun. Thus, I highly recommend that you shoot right before or after the sunset. It
will make your landscape shot look professional and beautiful.

9. Add a zoom

Adding a zoom is an easy way to create that nice and cinematic atmosphere to your shot. Keep it small and smooth, don’t make it too clear-cut or too obvious. This way, the viewer gets carried in really slow. The dolly zoom effect can also be a very cool technique, it is very effective for 4k footage which is outputed at 1080p for
the final video.

8. Add a sound clip

Music is like wings to the viewer’s mind. A piece of perfect matching music with your footage could help making your video popular. It beautifies your footage and brings the natural feeling in the video. Do not add music which doesn’t suit to your video, your video
might end up being weird in the end. It’s difficult but there are a million of audios on the Internet, get one with the permission and add it to your video.

10. Edit your video

To get the best out of your shots, you need to know how to edit your drone footage. It is one of the most important post-production processes. It manipulates and rearranges your shots for your the final product. Titling, color grading, sound mixing are very important tasks for aerial videography. Remove the unwanted footages, pick the best ones, create a flow, add effect, graphic, and music and you’re ready to shine.

Always bear in mind that, safety first. Drones are tools. You can’t treat them as toys.

Launch the drone into the sky within the law in your area and within your limits.

I hope with these quick tips you can explore and generate some cool content.

If you have more tips or ideas on how to make cool and professional videos please post them below!

Thanks!

Silent Arrow’s Autonomous Resupply Gliders

As reported this year by Thedrive.com’s The Warzone, gliders dropped from a variety of aircraft potentially could resupply small troop units in the field. Silent Arrow aims to resupply troops for half the traditional cost using disposable autonomous gliders. It turns out that researchers have already completed multiple deliveries using autonomous Silent Arrow GD-2000 cargo gliders launched from C-130 cargo aircraft. The GD-2000 can carry up to 1,631 pounds of payload and deliver it within 40 nautical miles when dropped from a fixed-wing aircraft from 25,000 feet. Helicopters offer a 15-mile standoff range. Silent Arrow claims it can deliver 26 cubic feet of cargo within 100 meters of the target destination.

How it works: “The GD-2000’s rectangular fuselage consists of a 2-foot by 2-foot by 8-foot container with a removable lid that contains the drone’s four 7-foot pop-out wings. Once loaded, the GD-2000’s nose cone and tail are installed on its fuselage and static lines are attached to its host aircraft. When the GD-2000 is pushed out of the aircraft, those static lines remove pins from the closed wings, allowing them to spring open even at airspeeds up to 130 knots. The gliders have a stall speed of 62 knots when half-loaded and 92 knots when fully loaded. …The gliders can be programmed using the Android Tactical Assault Kit, enabling them to be controlled by a variety of off-the-shelf or military mobile devices.”

Silent Arrow features a spring-deployed wing configuration, with a wingspan of 8.5m (28ft). It maintains a glide ratio of 8.4:1 when installed with a tail cone. Avionics include a Pixhawk Cube autopilot, magnetometer, barometer, GPS navigation system, and LiDAR rangefinder. First-person video and radiofrequency (RF) capabilities are optional. A smaller version of the glider is also offered. Photo sequence shows the GD-2000 WB (wide-body). Other versions include the electric-powered ER-2000, the GD-800, which is launched from an aircraft side door, and the GR-2000, which is for humanitarian aid missions.

Bio-Inspired Drones

Animal Dynamics, based in Oxford, England, works closely with the University of Oxford and specializes in aerial and maritime drones used for logistics, humanitarian aid, emergency services, defense and agriculture. Speaking exclusively to Express.co.uk at the recent Farnborough Air Show, Director of Business Development, Paul Topping discussed drones developed by Animal Dynamics, referring to the projects as “bio-inspired engineering.”
He said that the concept is making more efficient robots, based on an idea by Professor Adrian Thomas. “Professor Thomas, consults for the Ministry of Defence and Department of Defence, studied how animals lock onto targets, and how they morph their wings to fly in more effective ways.” He noted, “Adrian came to the conclusion that a flapping wing drone, like a dragonfly, would be more efficient, and work better than a spinning rotor.” Topping said the “Skeeter”design did turn out to be the best fit for the role. He added: “We developed a little thing that weighs around 150 grams, that can carry a camera, and can fly during strong winds, much like dragonflies and bees do so in similar weather.” Topping also noted Animal Dynamics has developed an underwater type drone based on a ray. Named the “Raydrive”, the equipment is a fully autonomous underwater system that uses a unique flapping propulsion technique. Its design, inspired by the gliding motion of manta rays, makes it ideally suitable for scouting and covert surveillance missions. At 1.3m wide, and still, in the early stages of the project, the Raydrive can pull a human along underwater. Images courtesy of Animal Dynamics. Listen to a related Podcast here.

The primary methods for converting audio or video to text

Transcribing recorded audio is one of the most important and least glamorous aspects of the creative process. Podcast producers transcribe interviews. So do TV news anchors and other journalists. You Tubers upload transcripts for their accessibility and SEO worth. We also know transcribing is vital because for years, everyone did it despite the fact that it was a great hassle, or incredibly expensive, or both. Transcribing manually from tape, or even digital media, was a time-consuming, error-prone operation. Try the best auto subtitle generator

Nowadays, technology has made video transcription much easier and less expensive. There are several transcription applications available, as well as internet firms that give relatively accurate transcription at reasonable pricing. There are several methods for converting video to text. The technique you select will determine the length of time required.

Transcription of videos by hand

It is precisely what it claims to be. Simply put, you transcribe audio recordings by listening to them and writing down what they say, complete with timestamps. Manual transcribing, is free and doesn’t involve the acquisition of any additional tools. Some artists find that manually transcribing their film helps they grasp what’s going on.

Do-It-Yourself Video Transcription

DIY transcription will refer to alternative types of transcription that do not require the use of external technological tools. It might be manual transcription distributed amongst a team, or it could be the use of proprietary transcription technology. Transcribing takes around four hours for every hour of video, so anything that might reduce that time is worth a shot.

Transcription that is automated

Consumer apps that mechanically transcribe audio and video have grown in popularity in recent years. All of these apps will boost your productivity significantly. However, you must still read over the transcript and look for AI-parsed problems.

Transcription from humans

Finally, you may use a human transcription service to transcribe audio recordings, which means you pay someone to perform the work for you. These kinds of services are useful when attempting to convert audio from one language to another. Translators typically detect sophisticated language connotations that AI does not. They are also the greatest solution when near-absolute precision is required. Many websites provide a human-powered alternative with 99 percent accuracy. It is more costly, as with all human-powered transcriptions.

There are other smartphone applications. YouTube’s automated captioning for YouTube videos, and the Mac Dictation tool enabling auto-transcription of audio. These tools, however, do not have as many capabilities as like the best auto subtitle generator.

12 tips to create incredible drone photos

OK, so you’ve mastered the basics of drone flight, have taken the obligatory photos of your house and the nearby empty field, and now you’re looking to take your drone photography to new heights. We’ve got you covered! In this article, we’ve compiled eleven tips that will tell you what to look for, how to frame up your subject, and tricks to create one-of-a-kind photos. What are you waiting for? Go ahead and elevate your art!

Shoot the horizon
The horizon is its own dividing line. Find interesting shapes, lines, and contrast there to capture an aerial image that tells a story. In this image, the setting sun provides a backdrop to the gold and green fields.

RotorDrone - Drone News | 12 tips to create incredible drone photos

Find dividing lines
Lines can direct the viewer’s gaze in a photo. An aerial view lets you use roads, trails, and even walls to create rhythm or patterns in an image that can become your focus. Breaking horizontal lines up with an object or intersecting vertical lines can also create interest. Keep in mind that horizontal lines work best when they are truly horizontal and square with the edges of your frame; otherwise, your image may look off-center.

RotorDrone - Drone News | 12 tips to create incredible drone photos

Take an aerial panorama
Many camera drones have a panorama feature that you can use to seamlessly meld many images into a single, wider view. Panoramas are ideal for overlooks or wide expanses—anyplace that has a wide, 180-degree view. Be careful not to shoot panoramas in wind because if the drone or objects in the image move, the program may not be able to stitch the images together.

RotorDrone - Drone News | 12 tips to create incredible drone photos

Remember the Rule of Thirds
When you’re framing up your image with your drone (or cropping in post-production), divide your image into nine segments with two vertical and two horizontal lines. If you place key elements where these lines intersect, you’ll have a more natural composition.

RotorDrone - Drone News | 12 tips to create incredible drone photos

Create an Illusion
Enlist props and a friend to create a scene that looks “vertical” when shot from above. Have your friend lay on the ground in a pose that makes it look like they’re upright and use other props or nearby objects to set the scene.

RotorDrone - Drone News | 12 tips to create incredible drone photos

Create Abstract Art
Look for interesting shapes and lines from your aerial perspective. Frame up multiple shots from various angles and heights. Often, just cropping in tightly on an area will create a type of abstract aerial photo.

RotorDrone - Drone News | 12 tips to create incredible drone photos

Look for repetition
Some aerial views provide a great opportunity for repetition. Carefully arranged objects can form precise, formulaic lines. A place like a shipping yard or train station can have a huge collection of identically-shaped objects. Even your ordinary neighborhood has a character with all its houses in a row. Appreciate the repetition with a great picture.

RotorDrone - Drone News | 12 tips to create incredible drone photos

Look for symmetry
A bird’s-eye-view allows you to find surprising symmetry, like the top of a gazebo in a park, a water fountain, or a town square. The entire image doesn’t need to be symmetrical; just parts of the frame can be symmetrical. Or you crop in on just the symmetry. The symmetry doesn’t need to be perfect; a break in the symmetry can catch your viewer’s attention and make the image more interesting.

RotorDrone - Drone News | 12 tips to create incredible drone photos

Capture Shadows
When the sun is low in the horizon, the light creates long shadows that you can play with to create wild scenes. Your subjects aren’t the interesting part of the image; their shadows are. Vary your drone’s height to elongate shadows.

RotorDrone - Drone News | 12 tips to create incredible drone photos

Find complementary colors
Keep complementary color pairs in mind when you’re composing a shot. A lush green forest is stunning against the fall-orange trees in this photo. For the best color contrast, keep things simple. The fewer colors in the image, the more dramatic and effective the contrast. Always be on the lookout for ways to juxtapose color complements.

RotorDrone - Drone News | 12 tips to create incredible drone photos

Zoom Closer
Although you never want to fly close to people, you can use your drone’s optical zoom capabilities to capture the personality of your subjects. Using your drone’s optical zoom function to take the photo instead of cropping in post-production will let you retain resolution and image quality.

RotorDrone - Drone News | 12 tips to create incredible drone photos

Capture unique patterns
Humans like patterns, so they make great focal points in an aerial photograph. Getting an aerial perspective is a great way to find unexpected patterns in ordinary places. Start by finding repetition, then re-frame it in a way that draws the eye. To draw the most attention to the pattern, remove any distractions.

Parrot Anafi USA – A diminutive drone with superlative features

If you’re looking for a first or second drone to explore the exciting world of aerial imaging, keep looking. If you are an experienced pilot working in public safety, industrial inspection or even the armed forces, stop and give the Anafi USA a closer look—it’s worth it.
A quirky platform built on a proven legacy, Parrot’s latest drone excels at providing powerful aerial imaging tools for professionals who need a clear view of what is happening on the ground when lives or big money are at risk. The extraordinary combination of thermal imaging and a visible-light camera with a 32x zoom capability are going to let you see what you need to see, right now.

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

With its remarkable 32x visible-light zoom capability and mid-resolution thermal imaging camera, the Anafi USA is well-suited for deployment with firefighters, police officers and other public safety professionals.

Lightweight

The Anafi USA is a study in contrasts, and it is important to understand the implications of the choices Parrot made in its design before making a purchase decision. Its imaging capabilities are legitimately powerful, and we’ll explore those in depth below, but let’s begin by considering the aircraft as a whole.

The first thing you will discover when you lift the aircraft out of its robust, protective case is that it is lightly built, weighing less than half other aircraft of similar size and capabilities. It weighs 499 grams, compared with a stout 1.1 kilogram for the Mavic 2 Enterprise Advanced. Initially, this lack of heft can make the Anafi USA feel almost like a toy—but that not a bug, it’s a feature.

I’ll never forget unboxing the original Anafi and feeling almost cheated when I saw how small and lightweight it was. However, it has since emerged as one of my favorite drones: its diminutive size and featherweight construction make it extremely efficient and quiet. That same characteristic also makes it more likely to withstand a crash with no or minimal damage—it just doesn’t weigh enough to hurt itself. Of course, that engineering approach has its limits, and those limits will no doubt be met much sooner while flying, and crashing, the Anafi USA: it is larger and heavier than its predecessor.

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

To direct the Anafi USA in flight, Parrot has once again returned to the proven SkyController 3. The same unit has also been employed by the original Anafi, the Anafi Thermal and the Skydio 2.

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

The gimbal on the Anafi USA incorporates three cameras: two, 21-megapixel visible-light cameras work in tandem to provide its 32x zoom capability, as well as a 320×256 FLIR Boson to capture thermal images.

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

The Anafi USA arrives in a case that is even more robust than the drone itself. Incorporating an O-ring seal and locking latches, it is sealed tight against water and dust. It even floats!

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

The ability to pitch its gimbal above the horizon gives the Anafi a big advantage in conducting thermal inspections: allowing the pilot to shift the background from the potentially hot surface (left) to the cool sky (right).

Nevertheless, expect to be surprised when you hold it in your hand for the first time. Also, if you’re the “drone guy” at your local fire district or police department and you recommend purchasing the Anafi USA for your agency, keep this effect in mind when you introduce your chiefs to their new, $7,000 purchase for the first time. Their initial instinct might be that you got scammed.
First impressions aside, the Anafi USA largely succeeds with this approach. The company claims a maximum flight time of 32 minutes. I have never once seen a drone hit its advertised flight time, but I have logged flights more than 27 minutes with this platform—and that’s lot closer than most aircraft I test.

Beyond its lightweight construction, Parrot attributes this performance to the scalloped trailing edges of its propellers: a feature unique to this aircraft, to the best of my knowledge. According to the company, this design was inspired by the pectoral fins of humpback whales. It allows the propellers to turn more slowly while applying greater torque. Thus, the company claims: “Anafi USA emulates a rotor whose power is higher than the theoretical capacity of its diameter,” and, “The tonal sound power of the anterior edge of the blade, is minimized, lowering the noise of the flight.”

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

With an IP53 rating, the Anafi USA is perfectly suited to fly in the rain as well as dusty environments that could cause problems for less well-protected aircraft.

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

With a thermal imaging camera and a powerful zoom lens, the Anafi USA would be a capable tool when deployed for infrastructure inspection.

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

The Anafi USA uses the exact same app—FreeFlight 6—that was employed by the original Anafi and the Anafi Thermal to display video and telemetry on the user’s smart device, making an easy transition for current Parrot pilots.

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

The pilot can select from three color palettes while employing the Anafi USA’s integrated FLIR thermal imaging camera: white-hot (top), black-hot (middle), and fusion (bottom).

So, is any of that true? I have no idea—I’m a pilot, not an aeronautical engineer. I will say that the Anafi USA is definitely quieter than other aircraft with comparable capabilities, and with its powerful zoom lens, it is capable of conduct up-close surveillance of a subject who is unable to hear it—an ability of potentially keen interest to law enforcement officers facing dangerous tactical situations.

Less is … ?

Read the list of specifications for any drone with the same general capabilities as the Anafi USA, like the Mavic 2 Enterprise Advanced or the Autel Evo II Dual and you’re going to find yourself reading a lot about sensors—specifically, collision-avoidance sensors. These drones make extensive use of binocular camera arrays and machine vision systems to build up a 3D model of the environment to help you avoid running into things, like trees, buildings, telephone poles, etc. Starting with the Skydio 2 from the eponymous manufacturer, the trend within the industry is moving inevitably towards 360-degree collision avoidance systems—front to back, left to right, top to bottom—your aircraft will be able to “see” everything around it, and sound an alarm if it gets too close.

In this regard, Parrot isn’t just marching to a different drummer, it’s sitting alone in the corner playing the theremin. The Anafi USA incorporates precisely zero collision avoidance sensors. Indeed, the only sensors it has—apart from the accelerometers and gyroscopes that are mandatory to keep any multirotor in the air—are a GNSS receiver that picks up signals from the GPS, GLONASS, and Galileo satellite constellations, along with a barometric altimeter, a compass, a single ultrasonic range finder and optical flow camera.

Except for the multi-band GNSS receiver, this would have been considered an underwhelming sensor suite five years ago. Today, it borders on farcical. And yet, plenty of smart people work at Parrot, so we are forced to consider the possibility that this is a deliberate choice, not a blunder. So, why not include all the bells and whistles? At the very least, all those extra features would look good on the sales brochure.

I’m sure that weight and cost were considerations, but I also think it is likely that Parrot though long and hard about their customer for this product, and what that person really needs to accomplish a mission.

My conclusion? That person looks a lot like me: an experienced, well-trained small uncrewed aircraft systems (UAS) pilot who knows how to fly. For the most part, I’m glad to have the collision avoidance systems that are standard equipment on most of the other drones I fly. They are re-assuring, even though I don’t trust them completely, and they serve as a check on my own perception while I’m doing proximity flying, for example.

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

Unlike drones from other manufacturers, the Anafi USA lacks any sort of collision-avoidance system: making it entirely reliant on the pilot to avoid obstacles.

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

The FLIR thermal imaging camera on board the Anafi USA has a narrower field of view than the visible-light camera at its most wide-angle setting, allowing the thermal image to be superimposed directly onto the video—aiding pilot orientation.

However, thinking back over my flight testing with the Anafi USA, I never once missed having it. I didn’t miss the warnings that, in the system’s judgment, I was too close to an obstacle. I also didn’t miss the warning that because the system was disabled—by me—I wasn’t receiving warnings that I was too close to an obstacle, and so on.
The beeping, the flashing lights, the alert messages—I didn’t miss any of it. Furthermore, I think I was at least as safe, or even more safe, than when I am flying a drone with a collision avoidance system. This may be true both because I was less distracted, but also because I had no choice but to maintain a higher degree of situational awareness myself, knowing the machine was not going to bail me out if I did something dumb.

Having said that, please keep in mind: this is one pilot’s opinion based on his own unique history, experience, and training. Like they say when you’re buying a new car: your mileage may vary, so think carefully about who you are and what tools you need to be the best, and safest, pilot that you can be.

Verdict: Not Stupid

American novelist Mercedes Lackey has a quote of which I am particularly fond: “If it’s stupid but it works, it isn’t stupid.” In many ways, this philosophy appears to be the animating spirit behind the design of the Anafi USA—right down to how you charge the batteries. The kit includes three, 3-cell, 3,400mAh high-density LiPo batteries.

However, rather than a custom charger with a proprietary connector, you recharge them using a standard USB-C cable. The included charger is basically one of those five-outlet USB power supplies that you would otherwise keep on your desk or your nightstand to recharge your digital life. You also get four USB-to-USB-C cables, allowing you to recharge all three batteries simultaneously, along with the aircraft controller.

This is a smart arrangement because you can get these components anywhere. Accidentally leave the charger for your Mavic 2 Pro at home, and you’re doomed. Leave the charging gear for your Anafi USA at home, and you can pick up a cheap replacement at any Best Buy. I use a Samsung Galaxy smartphone with the aircraft controller, so the charge cables even do double duty by allowing me to make that connection, as well.

The controller itself exemplifies a similar aphorism: “If it ain’t broke, don’t fix it.” You pilot the Anafi USA with the SkyController 3, first introduced alongside the original Anafi in 2018. It’s a compact, folding, all-plastic design. However, its simplicity is marked by a number of smart design choices. First, rather than the recessed dials that most manufacturers provide to control camera pitch and zoom, the Skycontroller 3 provides a pair of levers: a much more intuitive and easier to operate control interface.

Second, the simple act of unfolding the controller accomplishes three discrete tasks: it powers up the unit, positions the antennas for flight and reveals the mounting clamp for your smart device. The spring-loaded mount will hold your phone securely and accommodates the latest generation of smart devices—including my mammoth Galaxy Note 20 Ultra. However, I must first remove it from its protective cover to make it fit: a sacrifice that DJI does not require with its latest generation of controllers.

As Smooth as it Needs to Be

This minimalist approach even applies to the design of the aircraft itself. For example: it is so common these days for drones to incorporate a three-axis mechanical gimbal that it scarcely bares mention in the advertising. However, in keeping with the standard established by its predecessors, the Anafi USA only has a two-axis gimbal.

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

Sealing its motors was among the measures Parrot took to protect the Anafi USA from water and dust infiltration.

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

While using the thermal camera on board the Anafi USA, the pilot has the option either to look at the infrared image (above), or a hybrid composite that uses details from the visible light camera to improve clarity (below).

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

The Anafi USA and its 32x zoom capability allows infrastructure inspectors to get a close-up look at potentially hazardous environments, such as an electrical substation, while keeping the aircraft—and themselves—well away from it.

We could label this heresy—like the absence of collision-avoidance sensors—and smugly discount the aircraft entirely for failing to keep up with the rest of the industry. Once again, however, that would be a mistake.

The Anafi USA’s gimbal stabilizes the camera payload in the pitch and roll axes, keeping it level and on target when the aircraft is moving forward, backward and side to side. Unlike virtually every other drone on the market today, it does not offer mechanical stabilization in the yaw axis: that is, when the nose of the aircraft pivots left or right.

It turns out that this is not essential for acquiring stable video, at least in most cases. First, except for those rare drones that offer 360-degree rotation in the yaw axis—like the DJI Inspire series and big, Hollywood aerial cinema rigs—all the third axis does is smooth out the video when you make a turn, because the camera must ultimately end up facing the same direction as the nose of the aircraft, anyway. If you take it easy with your left thumb, you can still get smooth video, just like I’ve been doing with my original Anafi for years.

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

Thermal imaging is often employed by electrical inspectors to identify faults that are invisible to the naked eye—and the Anafi USA will allow them to literally take this ability to new heights.

Second, Parrot incorporates digital stabilization in all three axes, to supplement the mechanical stabilization provided by the gimbal. If you’re like me, you will be skeptical about this approach—and, obviously, I can respect that. However, Parrot has a history of success with this approach that bears noting.

When the first three-axis camera gimbals were arriving in the market, Parrot audaciously introduced a drone with a zero-axis gimbal: the Bebop 2. Instead of a gimbal, it relied completely on digital stabilization, and it worked surprisingly well—you could even “pitch” the camera up and down, just like a mechanical system. If you were only watching the video downlink, and had never actually seen the aircraft, you could easily be fooled into believing it had a conventional gimbal. The Anafi USA builds on that accomplishment.

Finally, this aircraft was not designed to deliver butter-smooth, cinematic aerial video—it was designed to provide crucial information for people in life-or-death situations. If you need to yaw hard to get the image you need, who gives a damn how it looks on video? To say otherwise is a bit like complaining that a firefighter’s handheld thermal imaging camera takes lousy vacation photos. It’s undeniably true, but it also misses the point.

I Can See for Miles and Miles and Miles …

For all its idiosyncrasies, the Anafi USA delivers where it needs to: as a serious aerial imaging tool intended primarily for people working in tactical environments. Even a cursory examination of the aircraft reveals a peculiar fact. It has three cameras mounted on its gimbal, not the two you would expect for visible light and thermal.

The reason for this arrangement is that it carries two visible light cameras: one with a 75-degree field of view (FOV)—comparable to the Mavic 2 Pro’s 77-degree FOV—and the other with a 16-degree FOV, which is the equivalent of 5x magnification. Since Parrot boasts this aircraft delivers an uninterrupted zoom capability from 1x to 32x, you would be right to wonder how this is accomplished.
The answer: digital zoom. From a magnification of 1x to 5x, the imaging system simply crops the image from the wide FOV camera. The absolute number of pixels in the image drops—if you capture a still image, for example—but the real-time image on your smart device remains perfectly clear. Then, when you hit 5x magnification, the system switches over to the other camera and the digital zoom process begins again.

At 10x magnification, the camera is still capturing the equivalent of 1080p video (1920×1080 pixels), which drops to 1280×720 at 15x, and then 720×480 at 27x. All the way out at 32x, you can begin to discern some pixelation in the real-time video, but I would judge the quality to be sufficient for applications like search and rescue. Also, Parrot made good on its promise: the zoom is smooth and completely seamless, even during the hand-off between the two cameras.

Except for their lenses, the two cameras are identical: capable of capturing 21 megapixel stills and 4K, high-dynamic range video at 24 frames per second. Each has 1/2.4” Sony IMX230 sensor with an F2.4 fixed aperture.

From an end-user perspective, the 32x zoom capability is impressive: so much so that it has the potential to change your perception of what drones can do. You can get an amazingly close-up view of people and objects that are a long way off—and that’s away from the drone, not you. I found I could reliably maintain visual line of sight with the aircraft out to 1,000 feet. Add the 32x zoom on top of that and you can keep watch on a subject more than a mile away.

That would be reason enough to deploy the Anafi USA with first responders, like search and rescue teams, firefighters, and law enforcement—but, arguably, we haven’t even gotten to the best part yet. The aircraft also mounts a FLIR thermal imaging camera: a Boson core capturing 320×256 pixels at 20 frames per second with a 50-degree FOV.

That sounds like pretty low resolution, and compared to visible light cameras these days, it is. However, for reasons that go well beyond the scope of this article, thermal cameras small enough to fit on a drone the size of the Anafi USA are always going to have limited resolution: topping out around 640×512. Furthermore, in my own extensive testing of aerial thermal imaging systems, I’ve discovered that resolution is not as crucial as you might expect for real-world tasks, like finding a missing subject in the woods or searching out hot spots following a wildfire. Make no mistake: I’ll take 640×512 if I can get it, but I wouldn’t regard 320×256 as being especially inferior alternative for most applications.

I do have one frustration with Parrot’s implementation of the thermal imaging system on the Anafi USA: the controls and interface are not well suited for professional thermography. For a soldier, firefighter or police officer interested in qualitative results, like finding people or judging how quickly a blaze is spreading, this system will work great. However, if you need quantitative information—like the temperature at the tip of a flare stack—that data is not going to be easy to access, which may limit this platform’s utility for certain types of industrial inspection.

Made in America

Although Parrot is based in France, the Anafi USA is manufactured in Massachusetts. The company is clearly eager to exploit the cybersecurity concerns around foreign-made (i.e., Chinese) drones, especially in sensitive applications like the military, public safety, and critical infrastructure inspection, and hasn’t missed any opportunity to highlight the drone’s country of origin.

To begin with, you don’t need to look any further than the name of the product: “Anafi USA.” And, just in case that was too subtle for you, the case is emblazoned with a label that reads: “Designed for the U.S. Army.” Heck, the only way they could possibly make this thing any more American would be to ship each unit with a six pack of Budweiser, a slice of apple pie, and a deep-fried bald eagle. Still, I don’t blame Parrot for banging on this drum repeatedly and hard: they are in a desperate fight for survival against a global hegemon, and they need to press every advantage they have as far as they possibly can.

RotorDrone - Drone News | Parrot Anafi USA – A diminutive drone with superlative features

To address the cybersecurity concerns raised by the U.S. government regarding drones manufactured in China and other rival nations, French-based Parrot is building the Anafi USA in Massachusetts.

The Anafi USA will be a benefit to these efforts. It strays from the established industry playbook in significant measure, but Parrot has always demonstrated an aggressive tendency toward outside the box thinking, and I think it serves them well in this case. Rather than pile on features because that’s what every other company is doing, Parrot gave some serious thought to the needs of the people who would be using this drone and built an aircraft to suit them.

Most of you reading this magazine will not need an Anafi USA, but it will be a real benefit to the few of you who do.

Photogrammetry vs. LIDAR – Choosing the right sensors for your job

In drone survey missions, the choice between photogrammetry and LIDAR depends heavily on the exact application. You also need to consider operational factors, such as cost and complexity. Knowing what outputs you really need will help you make the right decision.
What is LIDAR and how does its output compare with results obtained with high-resolution RGB cameras and photogrammetry? In this article, we’ll explore the ways photogrammetry and LIDAR are actually quite different from each other, even if their three-dimensional (3D) outputs look similar. We’ll then dig deeper into specific applications and how photogrammetry can provide exceptional results for most missions at a fraction of the cost and complexity of LIDAR.
Photogrammetry and professional, high-resolution cameras can cost-effectively generate 2D and 3D surveys, with absolute accuracies down to 1 cm (0.4 in) root mean square (RMS) horizontal and 3 cm (1.6 in) RMS vertical.

How Photogrammetry Works

In photogrammetry, a drone captures a large number of high-resolution photos over an area. These images overlap such that the same point on the ground is visible in multiple photos and from different vantage points. In a similar way that the human brain uses information from both eyes to provide depth perception, photogrammetry uses these multiple vantage points in images to generate a 3D map.
The result: a high-resolution 3D reconstruction that contains not only elevation/height information, but also texture, shape, and color for every point on the map, enabling easier interpretation of the resulting 3D point cloud.
Drone systems that use photogrammetry are cost effective and provide outstanding flexibility in terms of where, when, and how you capture 2D and 3D data.

The WingtraOne vertical take-off and landing (VTOL) drone allows users to conduct small- and large-scale drone surveys with unmatched data quality at a fraction of the time and cost of a crewed aircraft.

HOW LIDAR WORKS

LIDAR, which stands for “light detection and ranging,” is a technology that has been around for many decades but has only recently been available in a size and power feasible for carrying on large drones. A LIDAR sensor sends out pulses of laser light and measures the exact time it takes for these pulses to return as they bounce from the ground. It also measures the intensity of that reflection.
LIDAR uses oscillating mirrors to send out laser pulses in many directions so as to generate a “sheet” of light as the drone moves forward. Through measuring the timing and intensity of the returning pulses, it can provide readings of the terrain and of points on the ground.
The sensor itself is only one part of a LIDAR system. Critically important for capturing usable data, you’ll also need a high-precision satellite positioning system (GNSS) as well as high-accuracy sensors to determine the orientation of the LIDAR sensor in space—an inertial measurement unit (IMU). All of these high-end subsystems must work in perfect orchestration to enable processing of the raw data into usable information, a process called direct geo-referencing.
As the sensors have evolved, there’s now the option to capture aerial LIDAR data from one of two types of systems: classical manned airborne and lightweight UAV.
Classical airborne LIDAR surveys are conducted from a crewed airplane and are less accurate but capable of covering more ground than lightweight UAV LIDAR operations. Specifically, you can cover between 10 and 1,000 square kilometers (4 and 400 square miles) in one flight. The absolute accuracy depends on the flight height and sensor choice. At a typical flight height of 2,000 meters (6,600 feet) above ground level (AGL), you can expect an absolute accuracy limit of about 20 cm (8 inches) horizontal and 10 cm (4 inches) vertical.
Lightweight drone LIDAR systems cover as much as the drone allows per flight. As we will discuss in detail in below sections, these systems can be more accurate than those carried by manned aircraft. Specifically, fixed-wing drones carrying a LIDAR payload can cover up to 10 square km (4 square miles) in a flight, with absolute accuracy limits right around 10 cm (4 inches) horizontal and 5 cm (2 inches) vertical.
In both cases of crewed aircraft and lightweight drone LIDAR, the accuracy is significantly less than photogrammetry avails. Plus the post-processing for LIDAR absolutely requires expertise beyond a quick training or reading of a manual, as we’ll discuss below.

RotorDrone - Drone News | Photogrammetry vs. LIDAR – Choosing the right sensors for your job

A WingtraOne UAV equipped with a LIDAR sensor can create accurate 3D models with 2 to 3 cm (0.8 to 1.2 in) of vertical accuracy. These models can be used for precise volumetric calculations across a number of industries.

ACCURACY CONSIDERATIONS

As we have seen, photogrammetry and aerial LIDAR differ in the way points on the ground are registered. This directly affects the final point cloud accuracy and we will see that, especially for horizontal accuracy of areas free from dense forest canopy, photogrammetry clearly outperforms aerial LIDAR.

Photogrammetry. In the case of photogrammetry, a quality, high-resolution, full-frame sensor camera like WingtraOne’s Sony RX1R II can yield outputs with horizontal (x-y) accuracies in the range of 1 cm (0.4 in) and elevation (z) accuracies in the range of 2 to 3 cm (0.8 to 1.2 inches) over hard surfaces, enabling precise volumetric analysis.
Note, however, that in order to achieve such performance the payload used for photogrammetry must be a professional one, with the right image sensor and lens to capture more detail. It’s not just about the number of pixels. In fact, two cameras with the same number of megapixels and different size sensors provide different image quality and accuracy.
Proper mission planning and post-processing are also important for achieving optimal accuracy: good overlap among images increases accuracy and provides better error correction compared to complete reliance on the direct geo-referencing method used in LIDAR. A high-end drone system with professional mission planning and post-processing workflow helps ensure that you capture quality data that generates accurate results.

LIDAR. As for aerial LIDAR methods, the sensor does not target specific features on ground but instead shoots the beams at a set frequency in a defined pattern. Even if the horizontal accuracy of the single point might be higher, the best horizontal accuracy of a point of interest on the ground is limited by the point density.
Crewed aerial LIDAR can provide a point density of up to 50 points per square meter and offers a typical absolute accuracy of 20 cm horizontal and 10 cm vertical if flown at a standard height of 2,000 meters (6,600 feet) AGL.
By flying lower, lightweight UAV LIDAR provides a higher point density than crewed aerial LIDAR and can achieve better accuracy even though the laser is less powerful. Mounted on a multicopter, point density and the resulting point cloud accuracy can be improved by flying low and slow at the expense of reduced efficiency.
In the case of LIDAR on fixed-wing drones, a point density between 50 and 200 points per square meter is possible. This means a measurement every ~ 10 cm, so an absolute horizontal accuracy of about 10 cm can be achieved.
On top of limited horizontal accuracy, LIDAR-derived point cloud accuracy depends on the precision of the LIDAR itself and the quality of the INS (IMU and GNSS) system. Considering all technological advancements and system variables at this time, the typical absolute accuracy that you can expect from a lightweight LIDAR system on a fixed-wing drone is approximately 10 cm (4 inches) horizontal and 5 cm (2 inches) vertical.

While LIDAR can provide more detail underneath denser vegetation, both photogrammetry (lower graph) and LIDAR (top graph) can generate terrain models underneath sparse vegetation where the ground is partially visible from the air. (The data shown in this graphic was captured at 30 meters above the ground.)

Photogrammetry and LIDAR Applications

For most missions, 3D results achievable with photogrammetry are similar to those obtained with LIDAR, but with better accuracy and greater versatility, e.g., photorealistic outputs, thanks to the high-resolution visual data. There are some applications—specifically featuring power lines or large areas of dense forest canopy—where the higher expense of LIDAR for airborne missions is justified. Let’s look at the evidence for this across a range of actual applications.

Topographical maps featuring light vegetation (sparse tree stands or open canopy) are best surveyed with high-resolution RGB data capture. The resolution and photorealistic results are useful in cases like wildfire management in residential areas and have been used by some of the world’s largest urban fire and rescue services since the information serves many stakeholders who need a real view of what’s happened.

Topographical maps with medium vegetation can be obtained via a combination of photogrammetry and a method to capture the ground below the vegetation. To capture the additional information below the vegetation, ground survey methods or aerial LIDAR can be used. The combination with ground survey methods keeps the price down while guaranteeing high accuracy plus the resolution and photorealistic results available through photogrammetry.
While LIDAR can provide more detail underneath denser vegetation, both photogrammetry and LIDAR can generate terrain models underneath sparse vegetation where the ground is partially visible from the air.

Large-scale topographical maps featuring heavy vegetation are best acquired via manned airborne LIDAR. A digital terrain model (DTM) of the forest ground provides useful information for project planning in construction (e.g., the planning of new roads), forest biomass or detailed information on vegetation and habitats via topography and underlying terrain, applications falling under these circumstances will always require LIDAR at least in part to normalize topographical data.
Typically, state agencies try to maintain reasonably accurate digital terrain models (DTMs) of the forest grounds. For these kinds of large-scale projects with low resolution requirements, manned airborne LIDAR is the most cost-effective option available. If a more accurate or up-to-date DTM of a small forest is needed, a traditional ground survey will be the cheapest option available, yet lightweight drone LIDAR might fill a niche in-between.

Bare-earth mining, volumetric and natural resource surveys are best handled by high-end RGB payloads. Even massive surveys are ideal with the right drone and RGB camera. On top of this, photogrammetry is cost effective and saves time not only to capture and process data related to cut and fill volumes, stockpile assessments and status reports, but also to share this information and reconcile with contractors and stakeholders.

Power line surveys for vegetation control can be done with LIDAR or high-resolution photogrammetry and powerline extraction features on software like Pix4Dsurvey. For the sake of photorealism, price, and workflow, I recommend the latter option. Research is ongoing around photogrammetry as a go-to, cost-effective solution.

Powerline pole tower inspection benefits from live video inspection with a multicopter carrying an RGB or thermal payload. These are usually relatively small areas that multicopters can maneuver around and take oblique shots of easily and safely. With this method, you get all information within a very short amount of time. Zoom cameras allow detailed inspection that cannot be offered by photogrammetry or LIDAR..

Rail track inspection is still most often carried out from the ground—by a train equipped with ultrasonic, LIDAR, and visual sensors. Inspection from the air with either photogrammetry or aerial LIDAR is gaining more and more interest but both methods are in early stages. High-resolution photogrammetry offers data that avails outputs with all of the essential details accurately and autonomously while saving time. Plus the photorealism adds an element of easy identification and versatility that can answer to a range of questions.

RotorDrone - Drone News | Photogrammetry vs. LIDAR – Choosing the right sensors for your job

City mapping with vertical structures requiring 3D vantage points has been widely demonstrated with photogrammetry based on imagery captured with a payload featuring oblique capabilities. For cityscapes with many high-rises and intense levels of vertical detail, multicopters work well, although their ability to cover wide-spread areas per flight is compromised. VTOL drones carrying oblique payloads can still capture wide areas and achieve impressive vertical accuracy.

Operational considerations

The difference between photogrammetry and LIDAR grows when considering operational and logistical factors. To generate quality results, a LIDAR system requires all of its components to work perfectly in sync. Small gaps or errors in sensor measurements can lead to significant errors in outputs. Or worse, outputs that “look” right but are not. Techniques like ground control points (GCPs), which are useful in photogrammetry to correct issues, are harder to implement with LIDAR. Most of the time, the only solution for erroneous LIDAR data is to repeat flights.
LIDAR projects require an expert who understands the workflow and details of each subsystem and can recognize consistent and accurate data.
In contrast, photogrammetry-based workflows are more forgiving. The redundancy created by multiple, overlapping images of the same point on the ground enables error correction during processing and translates to high-accuracy outputs, even in non-ideal conditions or operations. The shorter learning curve for drone-based photogrammetry (even for operators with no prior experience), leads to greater flexibility and cost-effectiveness.
The ease of use of photogrammetry solutions like the WingtraOne translates into greater operational flexibility, the ability to deploy multiple systems to cover distributed sites, greater frequency of captures, and overall reduced costs.

RotorDrone - Drone News | Photogrammetry vs. LIDAR – Choosing the right sensors for your job

Photogrammetry allows the creation of accurate 3D maps of large areas. Photogrammetry outputs also include high-resolution visual data in full color for every point on the map to aid in the interpretation.

Final thoughts

We have explored the differences between how photogrammetry and LIDAR work and the similarities in their outputs and learned about situations where each technology can be best applied. And while some specific applications might justify the cost and complexity of LIDAR, photogrammetry can meet most of the everyday challenges presented across a range of projects and industries, providing exceptional accuracy and stunningly detailed maps, available on demand and with minimal expertise overhead.
So if you don’t need what LIDAR uniquely provides—specifically to mid- or large-scale forests with heavy but penetrable canopy—you can do more using photogrammetry coupled with a professional drone for significantly less money and complexity.

DJI AIR 2S – A test-drive

Strange things start happening once a company no longer has any meaningful competition, and the Air 2S from DJI is a prime example. Like all of the company’s offerings over the past several years, it’s an absolutely top-quality platform that provides robust capabilities in both its flight and imaging performance. However, it also has some important limitations—a few of them seemingly arbitrary—which it is important to understand before you buy it simply because you can afford it and it is the “latest and greatest” from the world’s leading manufacturer in the industry.

RotorDrone - Drone News | DJI AIR 2S – A test-drive

The Basics

To begin with, let us consider the Air 2S as a small uncrewed aircraft system (sUAS)—a flying machine that we intend to operate in the National Airspace System (NAS). In this regard, our top concerns must be safety, reliability, and performance. The Air S2 excels in all three categories. Incorporating an Automatic Dependent Surveillance-Broadcast (ADS-B) receiver, the S2 will alert you through the DJI Fly app when a crewed aircraft equipped with an ADS-B transmitter is in the vicinity.
ADS-B is nearly universal at this point on the type of small, general aviation aircraft that are most likely to be operating near us as remote pilots, making this an incredibly valuable tool. Unfortunately, it won’t tell you which direction or how far away the aircraft is, but you’ll likely see the warning before you can hear it. That gives you precious extra seconds to heighten your situational awareness of the surrounding airspace and begin a descent or other maneuvers to potentially move your aircraft out of harm’s way.
Regarding the question of reliability, circumstances didn’t permit me to log hundreds of flight hours to test the platform’s mechanical reliability or establish a mean time between failure. However, the S2 is reliable in that its performance is remarkably steady, even in extremely challenging environments. To test its ability to fly safely in high winds, I visited Hood River in Oregon’s Columbia River Gorge. Recognized as the kite surfing capital of the world, the wind blows constantly—and hard. Even with a pair of flags whipping in the wind behind it, the S2 hung stone steady in the sky.
At altitude out over the river, I received high wind warnings through the app, but maintained confident control of the platform throughout my maneuvers. This is an aircraft that will go where you tell it and stay put when it gets there. This is thanks to DJI’s highly refined flight control system technology, assisted by the fact that it incorporates a three-band global navigation satellite system (GNSS) receiver, picking up signals from the United States’ GPS, Russia’s GLONASS, and the European Union’s Galileo constellations.
Still, as always, it is prudent to take any manufacturer’s claims with a degree of caution. DJI claims the S2 can hover for 30 minutes on a single battery charge. During my own hover test, conducted on a 76-degree Fahrenheit day with no wind, I was only able to wring 23 minutes and 9 seconds out of a brand new 3,500mAH battery—and that was by flying the aircraft until it tried to initiate return-to-home on its own owing to a low-battery warning. When maneuvering, flight time dropped to 20 minutes and 10 seconds.
This is still a very good showing for such a small UAS, but I don’t know how you get to 30 minutes unless you’re flying inside one of those indoor skydiving machines turned up to 11.
Finally, when it comes to performance, the S2 is a potent little aircraft. Switching over to sport mode, I was able to keep pace with a kite surfer as she was literally flying across the waves while simultaneously holding my position against the wind blasting down the gorge. In calm air, the S2 provided tight, buttery-smooth controls making it as easy as it can be to pull off complex maneuvers like manual turns about a moving point.
While speed and maneuverability are crucial for capturing a dynamic still photo or video, they are also important for the safe operation of the aircraft: giving you, the pilot, the ability to quickly move away from an emergent hazard or navigate a complex environment. In this, you would be aided by not one, but two, forward-facing collision avoidance systems—with which one is active being determined by the speed of the aircraft and its pitch relative to the horizon. The S2 also incorporates a rear collision avoidance sensor, as well as belly-mounted optical flow system and an infrared altimeter.

Picture Perfect

Of course, the ability to fly safely and make aggressive maneuvers is all in the service of capturing aerial imagery. In this regard, the S2 is, once again, a top performer. Its three-axis gimbal mounts a camera with a one-inch CMOS sensor, capable of capturing 20 megapixel stills and 5.4K video at 30 frames per second. If your mission allows you to bump your video resolution down to “only” 4K, you are able to capture up to 60 frames per second.
I’ll refrain from offering my personal opinions regarding the performance of the camera. Instead, I captured a number of aerial photos across different environments that accompany this article, so you can judge the image quality for yourself. I will say that having a 20-megapixel sensor is a significant benefit if you are a professional photographer or enjoy making prints of the images you capture.
With a 20-megapixel image, you have the option to crop an image in post to improve the composition while still having plenty of pixels left over for high-resolution printing.
One nice feature is that the S2 itself incorporates eight gigabytes of internal memory for photos and video. That isn’t huge capacity, being only enough to capture 10 minutes of 4K video at 30 frames per second, but it is a nice reserve in case you forget to install a microSD card and only discover that fact once you arrive at your mission site.

RotorDrone - Drone News | DJI AIR 2S – A test-drive

The Air 2S features a high-intensity LED on the belly of the aircraft which can be activated from the controller. While it has the potential to ease spotting of the aircraft, the beam has a relatively narrow field of view—making it most useful when it is almost directly overhead.

RotorDrone - Drone News | DJI AIR 2S – A test-drive

With sport mode engaged, the Air 2S is an agile, high-performance aerial imaging platform, well suited for capturing dynamic sports such as kite surfing in the Columbia River Gorge. Just watch out for those shroud lines!

RotorDrone - Drone News | DJI AIR 2S – A test-drive

With a 20-megapixel camera and solid flight performance, the Air 2S would make a great small commercial UAS for missions such as monitoring the progress at a construction site, were it not for limitations deliberately put in place by DJI.

Your interface with the S2 is a conventional two-stick controller connected by a USB-C cable to your Android or iOS device, which provides video and telemetry downlinks as well as control over aircraft settings via the DJI Fly app. The controller itself mounts your smart device above the joysticks—instead of below them, as has been the case with DJI’s small, folding platforms since the release of the original Mavic in 2016. Bowing to industry convention in this regard is a welcome change for DJI, as the smart device is both easier to see and access in its new home.
However, it is in the pilot interface that some of the S2’s peculiarities begin to reveal themselves. To begin with, like DJI’s other recent controllers, the joysticks can be unscrewed from the gimbals and tucked away in a pair of notches built into the side of the controller. In theory, it’s a great way to protect the gimbals from damage and reduce the profile of the controller during transportation and storage. It can also have some less-beneficial side effects, unfortunately.
During one of my test flights, as I was returning to the launch site with a low battery warning, the right joystick managed to unscrew itself and fell on the ground. Given the totality of the circumstances at that moment, I wasn’t comfortable taking my eyes off the aircraft and kneeling down to look for it. So, I put my thumb directly on the gimbal and managed to bring it home that way.
This wasn’t a critical failure, but it could prove to be a significant distraction during a complex mission—and the fact that the “Fly More” combo comes with an extra pair of joysticks suggests that I am not alone in having this problem. This is something to watch out for and potentially even practice during your proficiency training with this aircraft.

RotorDrone - Drone News | DJI AIR 2S – A test-drive

The controller that ships with the Air 2S is notable departure from many of DJI’s previous designs: it mounts the display above, rather than below, the control sticks. The sturdy retaining clamp, large enough to accommodate the latest smartphones in a protective case, also houses the controller’s antennas.

Fly less

To interface your smart device with the UAS requires an app called DJI Fly. Upon learning this from the user’s guide, I pulled out my Android-based smartphone and typed “DJI Fly” into the search bar on the Play Store. To my considerable surprise—so much so that I actually screen-captured the page—there was no DJI Fly anywhere to be seen. Considering that maybe the name of the app was a misprint, I tried in vain to connect with the aircraft using the DJI Go 4 app.
Growing increasingly frustrated, I did a Google search on my laptop for “DJI Fly” and found a result on the DJI website. Pulling it up provided me with a description of the app and verified it was the correct option to use with the S2. At the bottom of the page, I spied a QR code that would allow me to download it to my smartphone. Incredulous, I launched my camera app and pointed my phone at my computer screen, thinking to myself, “This is not the way a leading 21st century technology company does business.”
After bypassing two separate safety warnings that “this type of file can do harm to your device,” I finally managed to get the app installed. Then, to my further surprise, I had to pair the aircraft with the controller. This made me think of nothing so much as binding a $150 foam airplane transmitter, prompting me to wonder why this had not been done at the factory—as it had been for the dozen or so other DJI drones I’ve owned and flown over the years?
Facing no meaningful competition in small UAS market, DJI no longer must confront the imperative of providing a seamless customer experience: why not let the customers do the work themselves and make a couple of extra bucks? It’s not like there are any other companies producing a comparable product at a comparable price.
After I had I updated the firmware and confirmed video, control, and telemetry links were functioning nominally, I headed out to the field to commence my test flights. One of the first things I discovered is that I really don’t like the DJI Fly app. The default view is extremely spartan with only the most basic flight information displayed. Items I’m accustomed to seeing on screen full time, such as the pitch angle of the gimbal, would only fade into being when I made an adjustment, and then vanish again a moment later.
Perhaps my greatest concern was with how the app displays feedback from the collision avoidance system. Rather than the familiar bow-shaped representation of the range to nearby obstacles that change from green to yellow to red as the aircraft draws ever closer, Fly applies an orange “glow” along the very edge of the screen to indicate where there are obstructions. For such a crucial piece of information, it’s too subtle and easy to miss.
I appreciate the desire for an uncluttered display, but the Fly app takes this laudable goal way too far. Immediate access to flight information is a cornerstone of situational awareness, and situational awareness is essential to maintaining the safety of flight.

RotorDrone - Drone News | DJI AIR 2S – A test-drive

The DJI Fly app offers a limited amount of telemetry, requiring the pilot to tap on-screen indicators for more detailed information about vital facts such as the direction home and the amount of flying time remaining.

RotorDrone - Drone News | DJI AIR 2S – A test-drive

Although DJI advertises the Air 2S will fly for 30 minutes on a single battery charge, practical testing revealed 23 minutes to be a more realistic figure, even in optimal conditions.

RotorDrone - Drone News | DJI AIR 2S – A test-drive

Even in a brisk wind that brings flags snapping to attention, the Air 2S is more than capable of holding its own, owing to its advanced sensors, flight logic and powerful electric motors.

Cui bono?

Two thousand words ago, I asserted that strange things start to happen when a company—any company—no longer faces significant competition in the marketplace. Essentially, it begins to compete with itself which, of course, is no competition at all. Instead, it seeks to herd its customers into product silos based on their ability to pay—even if that means effectively sabotaging their own offerings.
The first time I saw DJI implement this strategy was with the release of the ZenMuse XT2: a combined visible-light/thermal imaging camera system. The original ZenMuse XT had been compatible with the Inspire multirotor, being DJI’s only heavy-lift, interchangeable-payload platform at the time. However, by the time the XT2 was released, the company decided it would rather make $9,000 by selling you a Matrice M200 than $3,000 selling you an Inspire, so they made sure the XT2 was only compatible with the M200.
There was no technical reason that this should be true, but DJI realized that most of the entities purchasing the XT2 were fire departments and other public safety agencies, and they could afford a $9,000 drone.
The Air 2S is aimed at the high-end consumer or low-end professional aerial imaging market. It will give you great stills and video at a price no other company can match because they lack DJI’s economy of scale. However, the hardware could easily be put to use in more professional applications, such as orthomosaic mapping. No doubt the results it is capable of delivering would clobber my original Mavic Pro with its 12-megapixel camera, which I have used for countless mapping missions over the years.
However, that isn’t an option. Don’t take my word for it: ask the two industry-leading photogrammetry software providers. In the Pix4D customer support forum, a community manager named Kapil Khanal wrote, “Pix4Dcapture, our flying app does not support the Mavic Air 2S. At the moment, there are no plans to support it.”
Referring to the 2S’s immediate predecessor, the Mavic Air 2, DroneDeploy’s customer support team is even more direct: “While we support the latest versions of the DJI SDK known to work with Mavic Air 2, waypoint missions are disabled via DJI firmware on Mavic Air 2. Because of this, flight apps such as DroneDeploy, and even DJI’s own apps, do not allow for waypoint missions. As a result, users cannot fly autonomous missions with the Mavic Air 2 on the DroneDeploy App.”
There is not a doubt in my mind that the 2S hardware would deliver high-quality orthomosaics. However, DJI won’t allow that to happen because they have determined the people who do this type of work are able to pay $1,500—or more—for an aircraft that will, such as the Mavic 2 Pro or the forthcoming Mavic 3 series.
So, if you want to shoot aerial photos and video, the S2 is a great platform that will no doubt serve you well. However, it is equally important to recognize what it can’t do, and the fact that those limitations were a deliberate choice made by DJI.
All new journalists are taught to ask one question: Cui bono? Translated from Latin into English, it means, “to whom is it a benefit?” Here’s a hint: not us.

RotorDrone - Drone News | DJI AIR 2S – A test-drive

The aerial perspective provided by small UAS creates the possibility for unique images that would be difficult, or even impossible, to capture by any other means. With its 1-inch CMOS sensor, the Air 2S makes the most out of each opportunity.
