We just have this right now: image — machine vision — MicroPython 1.20 documentation (openmv.io)
This method will be refactored this year, though. I’ll be overhauling the lens correction code onboard such that we can do general purpose remap()'s like OpenCV from a lookup table with bilinear/bicubic sampling applied don’t the lookup table and then the pixel remap.
This will result in code that runs way faster since the lookup table can be generated once, and then we can remap pixels quickly with just bilinear blending.
