Im looking for a function that transforms a 2D image-point into a 3D line in my model (specific coord system, belonging to translation and rotation vectors received by function solvePnP() ).
I have: cameraMatrix, rotation and translation vectors, distortionCoefficients.
It would be the inverse function of projectPoints(), which takes a 3D point and transforms it into a 2d image point.
Is there any solution for this issue?
