Also if you're capturing photos in motion, definitely enable --rolling-shutter which will help compensate for the rolling shutter distortion of the DJI Mini 2's camera (it will take a bit longer to process though).

How does it compensate for rolling shutter? Out of curiosity :)

It implements the method outlined in "A two-step approach for the correction of rolling shutter distortion in UAV photogrammetry" by Y. Zhou and others: https://www.sciencedirect.com/science/article/abs/pii/S09242...

The Python code is probably easier to understand: https://github.com/OpenDroneMap/OpenSfM/blob/287/opensfm/act...
