Are there viable alternatives to the GoPro for mapping. I may end up building my own drone for this purpose, but it would be nice to use the Solo. I need to have continuous shots per second without having to keep hitting the shutter, and I dont think Go Pro supports that. Also the fish eye is making accurate photo stitching more difficult. Has anyone built any nice cost effective solutions that dont use the Go Pro? Thanks
I bought a used GoPro Hero 3+ Black on eBay ($127) and replaced the stock lens with a rectilinear lens to eliminate the fisheye effect. I first tried an Axion 4.35mm lens ($79), and it worked but I didn't like the quality. It's a 10MP lens, and the 3+ Black is a 12MP camera. The sales literature said it will work for a 12MP camera, but I'm not convinced after trying it. I then bought a 16MP 3.87mm lens designed for the Git2 camera and that works great in my 3+ Black. Nice quality lens, low to no distortion, and no fisheye effect. It was only $39 direct from the GitUp company web site. They also have a 4.4mm version as well, if I recall correctly. Must be an M12 mount for the 3+ Black and Hero 4 models.
It sounds like you're already doing mapping, but if not, grid (mapping) apps that I know of: iPhone - SidePilot. Android - Tower.
I know SidePilot snaps photos at whatever distance interval you set (not time) on the GoPro, but I don't recall with Tower. And I always use it on the gimbal, not the static camera frame. The downside to the Solo setup is that you have to manually enter the GPS data, which is kind of a pain, as you probably already know.
If you're planning to do plant/crop analysis with NDVI, disregard the above and get the IR/NDVI lens from Peau Productions, which is much more expensive.
I have a DIY drone that's set up to do this as well, but the benefit of sticking to a GoPro and the Solo is that everything is automated. Unless you want to switch to a Phantom and use DroneDeploy.
