How can I use these quads to deduce the rotations (pitch, yaw, roll) that caused the perspective distortion?
Notice that I used the cvGetPerspectiveTransform() which returns the perspective transformation coefficients in the form of a 3x3 matrix. I am able to use such coefficients to map a point from one space to another. However, it is the rotation angles which I'm concerned about knowing.
Any ideas?
