Web5 de out. de 2024 · The intrinsic parameters also include the camera distortion parameters. Refine the camera matrix to control the percentage of unwanted pixels in the undistorted image. Using the refined camera matrix to undistort the image. The second step is performed using the getOptimalNewCameraMatrix () method. 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.
