WebCalibration is only as accurate as the calibration target used. Use laser printed targets only to validate and test. Proper mounting of calibration target and camera. In order to minimize distortion and bow in larger targets, mount them either vertically, or laying flat on a rigid support. Consider moving the camera in these cases instead. 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. imt stevenson ranch apartmentsWebOpenCV camera intrinsic parameters do not include the skew of a pinhole camera model.
