In the traditional soccer video, it is difficult for the camera calibration technology to calibrate and provides the object’s three-dimensional height information and other issues, so this paper puts forward camera’s auto-calibration algorithm in soccer video. First of all, the two-dimensional model and threedimensional model of the court are defined and the improved the detection algorithm of court lines obtains the feature points in the court plane to solve camera’s isomorphic matrix, and then the solved isomorphic matrix is used to calibr...
