Analysis of Factors on Errors of the CCD Camera Calibration

This paper analyses the main effect factors of parametric accuracy in CCD camera calibration.and the practical camera calibration results based on these factors.In addition, this paper analyses the effect of light condition for the accuracy of feature extraction.The results show that the measuring precision of the world coordinate has a greater influence on the camera calibration, and 12 ~ 20 is the suitable number of images .Our research provide effective reference for well selection and manufacture of calibrating board in camera calibration, well choice of the number of images, and for obtaining stability calibration results.
