camera angle from perspective

Asked by Zoltan
on 14 May 2011
Hello! How can the camera angles calculated from the perspective distortion? If the corresponding points of the object (let's take a simple flat, rectangular object in the 3D space) and it's corresponding points in the camera image are known, how can be the angle under which the image was taken, calculated? I already calculated the homogeneous matrix, but I would need to know the angles.

Hi proecsm! Thank you for pointing to the camera calibration toolbox. I already had it, but unfortunatelly, when I used it, it predicted an object position, where the translation vector was ~2.7 times larger than the original, and also the objects rotation was ~45° instead of the expected 10-15°. It seems, that without knowing the proper intrisic camera parameters, like the field of view, the perspective angle can not be calculated.
