Zusammenfassung:A first calibration image of a calibration target is received and resized to provide a resized first calibration image. Pixel coordinates of the resized first calibration image are mapped to pixel coordinates of the first calibration image to provide a resizing map. The resized first calibration image is distortion-corrected to provide a distortion-corrected resized first calibration image. Pixel coordinates of the distortion-corrected resized first calibration image are mapped to pixel coordinates of the resized first calibration image to provide a distortion correction map. The distortion-corrected resized first calibration image is resampled to provide a resampled, distortion-corrected, resized calibration image. Pixel coordinates of the resampled, distortion-corrected, resized calibration image are mapped to pixel coordinates of the distortion-corrected, resized calibration image to provide a resampling map.
