摘　　要：该文分析了影响CCD相机标定参数精度的一些主要因素,并分析了在这些因素影响下相机标定结果。同时,分析了光照条件对角点检测精度的影响。实验表明,在保证角点坐标精度的前提下,标定板平面性对标定结果影响较大,图像数量取12-20幅比较合适。实验结果对相机标定中标定板的合理选择和制作、图像数量的选取、获得稳定的标定结果提供了有效参考。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.
