Hallo Michael,

I have to make a perspective correction of a round shaped object. It that also possible with your script or is does anything similar exist?

Or another question: Is it possible to create the A-matrix needed for the correction from the rotation and translation matrix I get from the cameracalibrator app?

Kind regards
Matthews
