Often pre-release cars are captured camoflaged using techniques from WWI. I find this fascinating, because while useful for preventing people from quite seeing the car, often these patterns seem super useful for computer vision-based feature tracking. The patterns might better than if the cars were their normal colors in many cases.
I don’t have time to play with this idea right now, but if someone wanted to extract frames and maybe auto-isolate some of those frames from the background, one could get a really good 3D representation of this spy video of (already released) Mercedes vehicles. It might be a fun, strange OpenDroneMap proof of concept use case. You know: a use case for all those OpenDroneMap car spies.
