:介绍了两种经典的摄像机标定精度评估方法: Tsai 提出的测量3 维世界精确程度的准则和Weng 提出

的NSCE、NCE 准则。在此基础上,提出了一种基于棋盘格长度的标定精度评估方法。该方法通过交会测量

得到的多个棋盘格的边长与实际边长的误差量来衡量摄像机标定的精度,能够比较形象地描述标定结果的

精度。-: Introduction of two kinds of classical camera calibration accuracy assessment methods: Tsai made the measurement accuracy of 3-dimensional world of norms and Weng raised NSCE, NCE criteria. On this basis, a checkerboard grid on the length of calibration accuracy assessment methodologies. The method is measured through the intersection of a number of checkerboard grid of side length and the actual side length of the error in terms of quantity of camera calibration accuracy and be able to compare the image to describe the accuracy of calibration results.
