Hello.
To compute movement of objects I need to find low resolution camera or other 2D sensor with high refresh rate, something like 16*16 pixels, with preprocess downscaling maybe and frame rate over 500 at minimal delay as possible.
Had big hopes about using mouse sensor with camera lenses to get shifted coordinates, but some lights make this idea non functional when they move or flicker. Custom workarounds required to fix such issues. Maybe some camera allow to read raw pixels in the center and skip slow sync procedures? In few posts here found esp32cam can use 96*96 resolution, but didn't find info which camera module is used (there are several, of course better with bigger lenses) and what refresh rate is at that low resolution, can it access fast enough on board to compute movement between frames. I thought about using horizontal and vertical linear array sensors like TSL201R, but single row and column can't be used to track diagonal movements, it must be 2D input.
