Calibration of X-Ray Stereo Vision System Based on Electronic Image

This paper presents calibration method of X-ray system. The calibration method of exterior parameters which refer to geometric relation of imaging system is introduced for translational system and rotational system respectively. The method is implemented based on stereo image pair. Unlike it, the method of interior parameters is based on a non-linear transformation according to the calibration model obtained from the information of corresponding points on a chessboard plane. The paper also provides some experimental results which can verify the effectiveness of our method.
