if it were possible to make a camera with a GPU or FPGA, there would probably be something, but it isn't. FPGAs and GPUs aren't (and can't be coerced to become) light sensors or structured light emitters.
Well you probably could get pretty far with 2 hardware synchronized IR cameras, a IR projector, and a FPGA. But the thing is, most hobbyists will just use two color cameras and AI instead.
I thought that RealSense cameras were just ordinary global synchronized shutter cameras with some stereophotogrammetry processor.
they use structured light; all the ones I have, anyway.
