I have my own camera calibration parameters. I am able to set the focal
length and the centering parameters and the skew cofficients, however am
having difficulty with my distortion parameters (in my calibration, I have
both radial and tangantial errors accounted for). Can someone tell me the
relationship between the gl_para for the opengl projection matrix and the
a little explanation of the 3 vector distortion parameters ( I assume for
radial distortion only) in ARToolKit would help a lot.
My image is centered correctly, but, is very radially distorted with the
camera I am using.
