  1. No. LAANC I controlled airspace with specific instructions, you must follow this instructions. If there’s an obstacle in your flight path that you won’t clear with the altitude restriction then you need to figure out a differnt path.
  2. A couple of things, unless things have changed there is no skills/practical test or part B as you call it. Kind of odd huh... I think teaching STEM as an alternative to “regular” education is a great thing to do. I’m curious what information your students gathered for their research and the methodology they used to gather it. Drones as an industry is not well defined and there’s a lot of hype on the internet so if you want your students to have a quality experience your probably going to have to filter the information they gather and put it in Context of a career path. They shouldn’t believe the raw data being spewed online. Not coarse that just my online opinion so take it for what it’s worth. Good luck and have fun.
  3. No worries. Good luck we’ve struggled finding operators willing to be road warriors
  4. We’re in a similar situation. The best advice I can give is that you need to grow your own. https://aerialalchemy.com/
  5. That has very little to do with what kind of drone or camera and everything to do with skill. There’s a good chance you could never be able to accomplish that. I’ve been flying drones since 2008 and I can’t come close to that. Maybe you can, but it’s going to take some serious skills. Also there isn’t a DJI that can come close to that.
  6. I’m a big fan of Aurdupilot and open source, however, Phillip Rowe’s answer to does it have encryption - “why do you need encryption?” Is kind of why trusting them to get this right is difficult. A lot of the so called “leading developers” really don’t seem to understand the commercial industry. Their just DIY’rs and there is no DIY market.
  7. What about your rights? Just because a drone is flying in the area doesn’t mean anyone’s privacy is being violated. I’ve never been there, maybe it’s just totally crowded, of coarse then you couldn’t fly there without flying over people, but using privacy as the standard is wrong. I guess they don’t allow cell phones either.
  8. It’s been a while since I’ve had any hands on experience with Ardupilot (I have people for that). But we’ve been doing some testing with various radars, IR, Laser, and other assorted sensors with varying degrees of success and failure. We fly mostly autonomous missions so we’re more interested in these sensors to enhance accuracy and not so much for collision avoidence. If people fly autonomous drones into objects they might want to consider a different line of work... Also, despite the hype from some manufacturers, the stand off distance for their “collision avoidence” is measured in feet. It might stop you from running into a static object like a building (if your going slow enough) but not much else. Like all open source projects PX4/Ardupilot has hooks in there software for a wide variety of sensors and variables for using them, but the application of them are not really that well thought through. We’re really busy but I’ll see if the guys that are testing have the time to respond to this thread. Unfortunately it might be a few weeks.
  9. I’m guessing your flying Aurdupilot?
  10. I believe these guys launched this about two years ago and like a lot of these types of efforts I don’t think they got much traction. Won’t know until they either launch a new website or pop up as a new company. I also seem to recall this Tx was pretty pricey. Only one of the cubes is not manufactured in China and the provenance of that one now in question. Turns out Hex66 is a Chinese company. Not a big deal for most people but for the type of security we have to comply with its not worth the effort to get the waiver. The HereLink is cool but it has the same security issue and although there’s a lot of talk about them they have not shipped many. But we’re keeping an eye on them and will probably buy a couple to play with. we’ve developed our own version of “LightBridge” “HereLink” that we can encrypt primary flight control, telemetry, and HD video with less latency for up to 25 miles. But, and it’s a big one, it sucks so much energy we can’t fly anywhere near 25 miles anyway. It’s good up to about 3-5 miles depending on how long you want to fly. It’s never easy!
  11. I couldn’t find it anywhere? Looks like the flight controller is PD4 using Q-Ground Control
  12. They came over from Italy and spent a couple of days looking at the work we’re doing and the tools we’re using. Our developers got along really well with them. There’s a ton of photogrammetry sortware available, it’s mostly all the same. Most of it is better than the capability of the people collecting the data. So for those using DJI, DroneDeploy is good enough. For those needing more accuracy with more resolution the choice is less and more expensive. It’s nice to see companies like 3DFlow recognize the potential market and focus some serious resources to move up the food chain. I really hope they can become more competitive in this space.
  13. It’s certainly a place to start to broaden your view of commercial drone usage. However, keep in mind it’s a trade show and a large percentage of it is drone people trying to sell stuff to other drone people and a lot of hype about commercial applications. If you don’t have much experience with commercial drones then it can be a bit overwhelming figuring out what’s real and what’s hype. What did you do professionally prior to your interest in drones?
  14. I guess it depends on how you define “first video..”. That is an excellent video, great flying, great location. Looks like a lot of fun. I did a similar video where we fly:
  15. I didn’t look back through this whole thread so sorry if this has been mentioned. Have you looked at Zephyr from 3DFlow? We use Bentley ContextCapture which is very good but expensive. We evaluated Zephyr and really liked the developers, something we don’t really like about Bentley. It’s not as capable as ContextCapture but if your using obliques it’s better than Agisoft, Pix4D and Correlator3D. Zephyr was developed for the entertainment industry but they are expanding into industrial inspection. Tell them I recommended it to you and they’ll probably dive you an extended evaluation https://www.3dflow.net/.
  16. Did the fishing boat have a radar? The GoPro BT usually only effected the Phantom 2's when it was mounted on the drone.
  17. Hi Bill, Kind of depends on how you define basic.. I use DaVinci Resolve. Not basic but its the industry standard for color correction that they've also added editing.
  18. Everyone thinks the key to photogrammetry is shooting obliques and the amount of overlap. Keep in mind that this is called PHOTOGRAMMETRY so the most important thing is your understanding of photography. Secondly is the software you use. There are predominantly two types of 3D reconstruction, one for mapping and survey and the other for 3D Models. Generally the software will work for both, but one is optimized for planar - NADIR, the other for surfaces - obliques. I have not used Agisoft, but things like DroneDeploy and Px4D are very limited with obliques. Here’s a sample of what we do in ContextCapture. Best viewed on a desktop. We use a Sony A7RIII, the lens and angle depend on altitude and FOV. These substations are energized so we usually fly around 100+ feet and fly 7m/sec. The key to a good model is not the overlap but the number of different angles you get in your coverage. We fly a combination of grid and orbits and for this level of detail we shoot approximately 5000-12000 shots depending on the size of asset. This model is a smaller piece of an eight acre facility. We consider substations to be fairly high frequency, lots of occlusion, but nothing compared to trees. I’m not familiar with your camera, but the higher the frequency the better the resolution, lighting and exposure need to be. Again, the collection of data is all about the photography. You can’t model what you can’t see and the sharper the image the better the model, motion blur has a very negative effect on the model. We never shoot below 1/800 so exposure can sometimes be a challenge. If the trees are dense then you need to capture it with A lot more angles, time permitting we will also shoot from different altitudes and focal lengths. Depending on the software you can’t go from 140 feet with a 50mm lens to 100 feet with 16mm lens, but changing it up adds more angles which helps build a better model. You’ll have to experiment with your setup to determine the right technique. Good luck, if this is your first attempt at Photogrammetry you certainly picked one of the harder things to model. Let us know how it goes.
  19. Welcome to the forum.
  20. The drone is totally unaware of airplanes, the NFZ is based solely on proximity to an airport. Unless a private airstrip is shown on a sectional it should not effect the NFZ. It’s a DJI, you can pretty much count on having that problem again.
  21. Was the plane circling an airport? Is there an airport in the area? Do you know what kind of airspace you were in? Your P4 has no way of knowing if there’s a plane in the area. Do you have a Part107? DJI has no-fly-zone NFZ built into its software that restricts your ability to fly in controlled airspace without a clearance. It’s inaccurate, unreliable and a real pain.
  22. Ive been to a couple of these. Aurdupilot and PX4 used to be the same thing. Lorenze is an interesting guy.
  23. Did you watch any of it?
  24. It didn’t look hot... what altitude is the city?
