Here's my 1st mapping test flight with a Skyhunter twin-boom pusher. Im running Arduplane 2.73. Mapping camera is a Canon s95 running an intervalometer script via chdk. Its suspended from a single axis gimbal that keeps the camera pointing down regardless of aircraft bank angle. Video shot from a GoPro 3 Black Edition.
It took 120 photos during the 10 minute flight, and stitched with PT GUI. I need to refine my grid spacing and polygon locations relative to the target area, and intervalometer timing. The generated map is a little rough, but its a great start.
I gave up on using the APM trigger at 3m from waypoint function as I couldn't get it to work and there's just no documentation on it.
Comments
The best camera triggering AP was Attopilot, I could script it to climb a little before the waypoint, shut the engine down stop navigation hold level and then trigger the camera. So you got rid of the gimble nonsense and prop vibration. Once the trigger happens, power on resume nav. All that said why exactly try and trigger at a waypoint, just fit a larger SD card and fly over the point several times with CHDK running (perhaps its folks who did not buy Canon that are worrying ;-))
Agreed. If they could only implement the 3m from waypoint function, then you could just define waypoints (single or multiple) and let the trigger do the work. Grid would work without having to add DO_Camera commands, and life would be good. :)
I am experiencing the same frustrations you had (maybe still have) about the "non support" to have the camera trigger functionality work on APM2.5. In your case you did not get it to make it trigger automatically at waypoints; in my case i do not even succeed to make it trigger manually using AN5 to AN9 (it seems ro only work using AN10 and AN11 but these are used for gimbal stabilization tilt/roll).
I would like to gather a group of people who would be ready to petition to developers of this community to correct these functions that we absolutely need for aerial photography. Maybe 3DR could also help provide a functional camera trigger for APM2.5?
Anyone interested in pushing this matter forward, please pm me.
Thx
Here you go. Have at it; Im looking forward to seeing the results.

I have agisoft too, if you want you can upload the dataset to somewhere and Kirill or I can make the orthophoto.
I think we all would be.
yep, I'll be purchasing :)
This keeps getting better and better! Thanks Thomas for turning me on to Autopano Giga. If did SOOO much better at analyzing the photos from multiple viewpoints. Heres the map run through APG. Ive dropped about 70% of the errors. Keep in mind this is still my 1st try at this, more photo overlap will get me closer to a true orthophoto. :)
Hi Matt, Matt Here,
Thanks for making this info availible, I am very excited to see your success, Congrats!!! We are looking to do much of what your doing on a deer and elk survey project out in California. Would love to trade notes and pick your brain a bit. While equipment lists and settings are all well and good, we both know the devil is in the details.....
Matt, you can also try for stitching, for free, Microsoft ICE
