摘要：

针对摄像机标定,提出了一种基于B-dual-space的改进型平面标定法。首先介绍了B-dual-space的概念和基本性质;并将B-dual-space与张正友的平板标定法相结合,提出了改进型的平面标定算法,这一方法继承了张的方法中二阶畸变模型的使用,相较Tsai的方法畸变模型更精细;然后,用棋盘标定平板实验验证了算法的有效性,通过与另外两种经典标定方法的标定结果比较,显示该方法的精度与张正友的方法接近。

Abstract:

For camera calibration,this paper presents an improved plan calibration algorithm based on B-dual-space.First,the concept of B-dual-space and its basic properties are introduced.Second,the paper creatively combines B-dual-space and Zhang's method,proposing an improved plan calibration algorithm.This algorithm also uses the second-order distortion model which is more elaborate than the first-order distortion model that Tsai's method uses.Finally,the efficiency of the algorithm is verified by the checkerboard experiment.A comparison with the other two classic calibration algorithms shows that the accuracy of the new algorithm is approaching to that of Zhang's method.
