present the calibration pictures. dropbox/gdrive/whatever works. I’m just looking to browse them superficially, for typical mistakes. if you want to, you can blur out anything you don’t want people to see.
stereo isn’t “low cost” anymore if you have to sink a week of your time into it. unless you’re doing this for the learning experience, I’d recommend just buying an “RGBD sensor” like a kinect or intel realsense or whatever’s popular these days.
