Solving Intrinsic Parameters of Camera Calibrated from Controlled Motion Sequences and Homography

Abstract:

A camera calibration based on controlled motion sequences and homography is adopted. First condition of unique solution for constrained equation set is proofed. Then two sets three orthogonal motions are carried out for camera in manipulator, thus 6 homographic matrixes of plane are obtained at 7 view points, and thus the intrinsic parameters of camera are achieved. The experiments on real images validate our technology based on homography.
