But before that, we can refine the camera matrix based on a free scaling parameter using cv2.getOptimalNewCameraMatrix (). If the scaling parameter alpha=0, it returns undistorted image with minimum unwanted pixels. So it may even remove some pixels at image corners. http://www.iotword.com/4934.html texas vs texas tech football 2003
