Abstract:In order to solve the problems of high precision and wide field of view in multi-view vision measurement system, a camera calibration method based on beam adjustment method is proposed. The spatial coordinates of each coding point are reconstructed based on the stereo vision principle, and the coding points were projected into the image through the camera imaging model. Then, Levenberg-marquardt method is used to minimize the projection error between the coding points and the corresponding image points in the image, so as to obtain the optimal camera parameters. The experimental results show that the maximum calibration error of the method is 0.052 9 pixels. Besides, the camera calibration accuracy is high, and the application scene is flexible, meeting the needs of industrial applications.
