An algorithm for self-calibration in active vision

摘要

A new algorithm for the calibration of intrinsic parameters of cameras in active vision is presented. By making two displacements of camera, linear equations are obtained from epipolar structure to slove the scale factors. The trajectories of fretures are used to located the image center. The computation is simple and easy. This method doesn't require special calibration objects or scene structure. The algorithm is implemented and validated on digital simulation and real data image experiments.
