Hi.
I would like to calibrate a projector to get a undistorted image on surface.
It is not possible to project a chess board because of many shadowed areas.
I have projected a grid 5x7 and measured the distortion manually in pixel for x any y. (See table below)
Now I need a way to calculate the InputArrays cameraMatrix and distCoeffs which are used in cv::undistort(…) -function.
Is there a way (in C++) to do this with the available parameters in table?
Thanks Egon
