Improvement of Two-Stage Camera Calibration

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.
