| 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... |
