Corner Detection Method Used in Calibration of Camera and Its Improvement
摄像机标定中的角点提取方法及改进

In this paper, the calibration principle of a camera is presented in brief. Two groups of corners are detected by using a Harris corner detection algorithm and an improved algorithm based on Harris respectively. The Tsai algorithm is used for the calibration of the camera and the calibration results are used to reconstruct the world coordinates. Finally, the errors of those two detection methods are compared.
