  1. Lots of great information in the thread, wanted to specifically answer these as they relate to the course. Yes, you can get a rough elevation profile. As others have noted, anything that moves is difficult to model, and not as accurate as lidar. I'd suggest checking out outputs that Drone Deploy offers. You would be able to estimate volumes of soil to move, take rough measurements, and get updated maps based upon changes to your property. You can do all of this with inexpensive equipment. A Phantom 3 Advanced and above from DJI all have this capability (except low end options
  2. Frank, There is an online course, you can find it here: https://learn.uavcoach.com/p/mapping-and-modeling 1) It is related to drone "surveying" and mapping. "Surveying" because it is taking known measurements the way a surveyor typically would. The level of accuracy is not as absolute as these methods. That said, it is still quick, cheap, actionable, and "good enough" for many applications. 2) The course is online! 3) It is NEVER too late to register. The course is self paced and available 24/7. Let me know if you have any more questions! LB
  3. Michael, I'm sitting next to the same setup that you have currently (although I use it more for visual work). You can use it, I'd advise using Drone Deploy or the DJI GS Pro app. The shorter the lens the better. If you put on a 45mm lens, that is a very narrow FOV. I'd go with a standard shorter lens of 12/14/15 or whatever their packages currently are. We discuss parameters that will drive what altitude you want to fly at. With the x5S you could fly 200-400 and still have great outputs, which should be above most obstacles. The course does not cover correction for the Z axis. That
  4. A lot of these types of conversations end up going back to just how "accurate" is "accurate". For professional surveyors who need to provide precise measurements, the outputs from Drone Deploy and a P3P aren't going to be very impressive. For someone who just needs to do a quick audit of a stockpile or figure out how many dump trucks they need, they are accurate enough given the cost/speed at which data is available. There is probably variation within Drone Deploy as they provide different processing speeds.
  5. I should know more about the difference between the models, but this looks like the earliest frame w/ that carbor fiber pattern, but the props lock on and don't need the prop nuts? Is that correct?
  6. Zane, Sorry about the delayed response. I thought this forum was getting folded into the other. The coordinate data has two important pieces here: 1) Quality of the data/position. This is what you are referring to w/ the HDOP etc. If those values are good, they will be more precise (but not as good as survey level data). 2) Embedding that data to the JPEG file (or whatever format) so it can be easily read by the processing software. You could/can overcome geotagging issues with the photogrammetry process, but as you have larger data sets, it introduce either a lot mor
  7. No, we didn't cover adding in tags to the 3D models. If you look at the demo we have on sketchfab, that is a skechfab feature.
  8. You'd want to use Pix4D or Agisoft Photoscan. I'm not sure why you'd shy away from web based processing. They give you the models/data, and are a lot faster. If you were concerned about quality/precision at a high level, offline makes sense.
  9. I'm not quite sure what is going on in this thread? Did we resolve the problem? Updates?
  10. @xGk04x You can sign up for a basic version of Drone Deploy for $100/month, or process maps as needed at Maps Made Easy and buy points. You could show them what is possible with a $600 Phantom 3 Advanced and a couple hundred bucks of processing. Skycatch has a $49 package, but at this point your money is better spent with Drone Deploy.
  11. I think it depends on what you are trying to model. For most things, I don't think it is going to provide significantly different results. A few oblique shots will help a lot though.
  12. I'd just in here and also say to get that much detail, you are going to have to pay for the additional processing, etc. At some point the benefits of more detail aren't worth the cost. If you get too close, and all the images show similar things (pine trees), it is hard for the software to give you a clear picture. It could make things worse.
  13. Tim thanks for the question. I personally do not calibrate when I swap batteries as long as the area I'm flying doesn't concern me. If I'm flying somewhere that the margin for error is small, or I'm around items that are likely to increase error, I might be more likely to calibrate. Depending on the software / UAV, it might be the case with the inspire you have to manually take off, upload the flight, and then hit play on the mission.
  14. I personally really like using the Phantom when possible. Less stuff to keep firmware updated on, it draws less attention, easier to travel with, etc.
  15. Anyone jumping on this? http://www.oemcameras.com/uav-drone-components/3dr-gimbal.htm?mc_cid=dac49e8ca2&mc_eid=cbf977becc I think the integration with DJI is still going to be better (even if it is a bit more).
