: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:

Camera calibration consists in the estimation of a model for an un-calibrated camera. The objective is to find the external parameters (position and orientation relatively to a world co-ordinate system), and the internal parameters of the camera (pri

利用Tsai两步标定法实现摄像机的标定，里面有官方给的世界坐标和图像坐标便于理解-Tsai calibration method used to achieve two-step camera calibration, there are official to the world coordinates and image coordinates of easy to understand
