Abstract: The two-stage camera calibration is introduced firstly, and then the improvement on it is given. Through the nonlinear optimization of the results obtained by two-stage camera calibration, the pre-calibration of the image plane center of the CCD camera can be omitted, so the process of calibration is simplified, and the precision of calibration is improved at the same time.

Abstract: The space relationships among flange coordinate, camera coordinate and calibration reference coordinate are analyzed. A simple calibration method for the relationship of the eye-in-hand of robot vision is proposed and corresponding experiment system is designed. The result of experiments shows that this method can work simple and shortcut with higher precision.
