returns the coordinate system and calibration matrix of a camera


Use carefully: The 'TofcamVLPL' function has not yet been extensively tested

Description

Useful for calucating the center and camera angle of a c-arm.
VL and PL must have the same length!
In case of a real c-arm it is tried that the image should have the focus length is the distance between the x-ray source and the detector.
