Is it possible to use the hi-res camera or wide angle hi-res camera for optical flow tracking (downward looking), or do we need the black and white 640x480 tracking cameras for this purpose? We have the stereo tracking cameras mounted for forward obstacle avoidance and tracking thus far and LiDar for elevation measurements but would ideally also have optical flow set up to track all three movement axes in GPS denied environments. Our purchasing agent bought what he thought were the optical flow cameras and came back with the hi res camera.

The VIO algorithm is highly tuned to that fisheye tracking camera. It is possible to use others, but performance could degrade pretty quickly.

So it sounds like Dan bought the wrong cameras
