摘要
摄像机标定系统的标定精度对于计算机视觉三维测量的精度至关重要,在Tsai的标定精度评估准则的基础上,给出了一种基于棋盘格的标定精度评估方法。该方法利用标定结果重构一组棋盘格长度,将该长度与实际的棋盘格长度进行比较,进而测量标定系统的精度。
The camera calibration system precision is very important for the precision of computer vision three-dimensional mearment. On the basis of Tsai＇s calibration precision evaluation rule, a kind of calibration precision evaluation based on checkers is proposed. The calibration result is used to work out a set of length of checkers, which are compared with real length of checkers to measure the precision of calibration system.
