| Abstract: | This paper describes the camera calibration algorithm which is needed when given only the center-to-center distance between adjacent CCD sensor elements in the vertical distance. In order to obtain the accurate solution of camera parameters, the combination of generalized Newton optimization algorithm and pseudoinverse algorithm is used to solve the non-linear equations. Camera calibration error is introduced to evaluate the camera calibration accuracy. The experiment results of CCD camera calibration are shown. By use of computer simulation various factors which affect the camera calibration accuracy are analyzed. |
