I have a system with a robot picking parts based on feedback from a distance sensor. I have found that errors in alignment etc can cause problems over the working range. I want to create a correction factor. I have collected matching robot/feedback locations for the 4 corners of the working range.

I’m looking for a way to find the best transform that will convert a feedback location to a robot location. I’m expecting a non linear scaling and a translation.
