  1. 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.
  2. 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?
  3. 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 more processing power, or the chance for more error. The hit or miss comment probably came from us geotagging early on with a custom built UAV and adding geotags after the flight. If you end up with one picture too few/many, or don't pull the right flight log, etc. In our minds it just adds another step and another spot to potentially screw up. The accuracy will never be constant until the sensors get much better. Without knowing which video, my guess is our advice is aimed at encouraging people who value their time to make sure they don't have to do this unless there is a good reason to do so. I don't feel like I've completely answered your question, just wanted to clarify our position.
  4. 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.
  5. 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.
  6. I'm not quite sure what is going on in this thread? Did we resolve the problem? Updates?
  7. @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.
  8. 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.
  9. 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.
  10. 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.
  11. 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.
  12. 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).
  13. @olesailor You can use the P3P and the P3A (and anything above). The P3S doesn't work (it is pretty limited). We cover everything you need to know about using your Phantom to do models and surveys/maps in our class!
  14. You'll want to look into Canon cameras you can hack and trigger with Pixhawk. @evan.roy
