WebOpenCV comes with two methods, we will see both. 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. WebCamera Calibration Calibrate single or stereo cameras and estimate camera intrinsics, extrinsics, and distortion parameters using pinhole and fisheye camera models Camera calibration is the process of estimating camera parameters by using images that contain a calibration pattern.
