I have a transformation matrix (as a projective2d object) created with fitgeotrans(), which should be used as an image correction, and a simulated image, which I want to use for validation of this transformation matrix.
The points used as input for fitgeotrans() are calculated before based on some measurements, which works fine.
I apply the transformation matrix via the imwarp() function onto the simulated image. But now it seems that the correction is applied with the origin at the wrong point.
How can I change that, if the points used as input for the fitgeotrans() are assumed to be correct? And I do not think that the transformation matrix changes if I change the input order of the points in fitgeotrans(). (As long as the fixedpoints and their corresponding movingpoints are at the same position.)
Edit (30.11.2021): After some additional research, I have the suspicion, that i should maybe ask the question differently: How can I apply the transformation matrix so that the origin on the matrix is in the center before and after correction?
Any help is appreciated.
