Sorry if this has been done before. I usually reside over in the Vision forum. Anyway is anyone using a Gopro, Phantom 2, 3d gimble, and waypoints for larger aerial surveys? The likes of farms etc. I was thinking with the gimble pointed straight down you could get decent photos to be mosaic together with appropriate software. My questions are. Is anyone doing this? What software did you use? Obviously fish eye will be a problem. The likes of Pix4d seem to support Gopros, however at $10,000 I would like to start somewhere a bit smaller.
