      【摘要】 对导轨CCD测距系统标定方法进行了研究,运用坐标转换运算求取了主点坐标、面阵CCD的纵横比和相机位于导轨左右位置时的位置关系,改进Tsai标定法对镜头焦距和镜头径向畸变进行了标定。设计了导轨CCD测距系统的标定实验,实验结果表明,标定后导轨CCD测距系统的测距精度有所提高,标定方法实用有效。
【Abstract】 In order to improve the ranging precision of the guide CCD ranging system,this paper studied the calibration method of guide CCD ranging system.By use of coordinate conversion,the relationship of principal point coordinates,CCD array operation aspect ratio and the camera location was calculated,the focal length and radial distortion of the lens were calibrated by improved Tsai’s method.The calibration experiment for guide CCD ranging system was carried out.The experimental results show that the ranging accuracy is greatly improved after calibration.
