Abstract :
A new algorithm for the calibration of intrinsic parameters of cameras in active vision is presented. By making two displacements of the camera, linear equations are obtained from the equipolar structure to solve the scale factors. The trajectories of features are used to locate 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
