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.

Key words: camera calibration;B-dual-space;vanishing points
