Hi everybody,

I recently purchased a ready to fly 2014 Y6 from 3D Robotics with a Tarot gimbal and GoPro camera. My problem is that I really need gps points on all of my photos so I can stitch them together and analyze them. Another thing I'd like is to be able to use an infrared camera that has a gps.

So my question is, does anybody know of a gps attachment for a GoPro camera? Or recommend a different camera and gimbal for these purposes. I would like something I could just hook up and start taking pictures with out too much configuring in Mission Planner for a new gimbal.

If that is not an option, does anybody have any advice on geo-tagging images? I've tried to use Mission Planner for geo-tagging and I've followed the instructions on how to do it with Mission Planner. For some reason after I go through the process, there is no latitude or longitude information on them, or it says "invalid log" and the process gets stopped.

My purpose is to analyze agricultural fields for crop scouting and decision making.

I appreciate any advice,

 

Thanks!

Morgan

  • Did you do the modifications to the SX 260 yourself?  Also, what altitude did you find to be the best for stitching the photos together?

    • No, I didn't do the modifications myself. They were purchased through Event 38, but I have seen tutorials on how to do the modifications while browsing the internet. dronemapper.com was the best success I've had so far on stitching images together, but that is probably because I don't have much experience with doing it with any particular software yet. My next step I'd like to accomplish is to be able to stitch my own images together. As far as dronemapper.com goes, they have altitude, overlap, and camera angle requirements on their website that you must follow for them to be able to process your photos. I believe the minimum altitude was somewhere around 80 meters. Here is the guideline link: http://dronemapper.com/guidelines

      The only issue I've had with flying at that altitude is that when the crops we are flying over are still small, they don't show up too well flying that high. If anyone has advice on that it would be very welcome as well!

      Sorry if this is a little long winded, I hope that helps! There's still plenty of parameters I need to perfect.

       

  • I guess it is hard to find such cameras like Canon 260/230 since they are out of production 

    • I have used a Canon SX 260 that was converted to near-infrared capabilities in the past. It works really well since it has GPS, definitely an improvement from the GoPro in my opinion. At least in the way that I know how to use them. I am somewhat of a beginner. I still had problems with the stitching photos together, I was sending them to dronemapper, but sometimes the gimbal would not hold the right angle it needed, or I was not at a high enough altitude and they could not be processed.

      Ravi: they're in stock at the Amazon link I provided above.

  • 3D Robotics

    The Canon SX230 has GPS and can run CHDK

    • @Chris:

      Why don't you (3DR) actually sell pre-modified point-and-shoots with IR cut removed and e.g. InfraBlue filter installed? That would be a huge help for all people interested in IR/NDVI imagery who don't have the fine mechanical skills to mod the camera themselves...

      • 3D Robotics

        Stefan: If there's enough demand we could do that. We're getting pretty good at it!

        My favorite mod was converting a Fuji 3D camera with two lenses so that one was NIR and the other was regular. That way we got both images for a NDVI merge in each shot, perfectly aligned!

        • Very cool Chris!

          I think, there would be enough demand to at least teach 1 or 2 people of your staff how to do it, put it to the shop and make those on order :).

          Publiclab is just coming out with a modded Moebius cam with a filter and custom white balance for composite NDVI and you might have noticed that I successfully asked the developers of the MLT framework to add composite NDVI processing to MLT (which is used by a number of video editor programs on Linux and Windows). On a fast PC, that processing could even work semi-realtime.
