Great post Petr, I've used Photoscan for aerial images myself.  How do you think a GoPro using continuous still photo shooting (ever 0.5 or 1 second) would stack up against extracted stills from video?

Hello, Stephen. A set of still photos will perform better in most cases, except for the one, when some images have wrong exposure or focus. It is easier to select properly exposed and focused frames from 50 FPS video.
