Publication number: 20250244571Abstract: A method to fine-tune extrinsic parameters of a fisheye lens applied to surround view splicing is provided. Fisheye images are obtained from multiple fisheye lenses. Both sides of the fisheye images contain calibration boards. Initial extrinsic parameters are obtained based on the fisheye images. Multiple corner points of the calibration boards in the fisheye images are detected. The corner points are arranged so that the corner points are connected into a quadrilateral in sequence. The initial extrinsic parameters are multiplied by a fine-tuning value to obtain intermediate extrinsic parameters. The corner points are projected to a top-view projection by using the intermediate extrinsic parameters. The intermediate extrinsic parameters are adjusted according to the shape, size, and overlapping effect of the area surrounded by the corner points in the top-view projection.Type: ApplicationFiled: December 30, 2024Publication date: July 31, 2025Inventors: Fan DONG, Chao-Chin CHANG
