Is there a way that the OpenMV Cam M7 can create a mapping grid? I have noticed that the Cam cannot perform SLAM algorithm.

There’s no one function to do that (yet) but maybe you can use keypoints and/or phase correlation.

SLAM requires the camera to keep history of the scene in RAM. This is likely not possible nor something we really want to do. I’ve tried to shy away from code that requires any prior history given the previous frame. You’d need to keep a rather large memory structure that grows per frame to do SLAM.
