We extend the calibration procedure\r\nproposed by Scaramuzza et al. by replacing the residual function and joint refinement of all parameters. In doing so, we achieve a more stable, robust and\r\naccurate calibration (up to factor 7) and can reduce the number of necessary\r\ncalibration steps from five to three. After introducing the camera model and\r\nhighlighting the differences from the current calibration procedure, we perform\r\na comprehensive performance evaluation using several data sets and show the\r\nimpact of the proposed calibration procedure on the calibration results.","url_abs":"https://www.ipf.kit.edu/downloads/Preprint_ImprovedWideAngleFisheyeAndOmnidirectionalCameraCalibration.pdf","url_pdf":"https://www.ipf.kit.edu/downloads/Preprint_ImprovedWideAngleFisheyeAndOmnidirectionalCameraCalibration.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"improved-wide-angle-fisheye-and","repo_url":"https://github.com/urbste/ImprovedOcamCalib","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[{"task_slug":"camera-calibration","task_name":"Camera Calibration"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
