For rectifying the lens distortion, forward distortion model needs\nto be known. However, many self-calibration methods estimate the inverse\ndistortion model. In the literature, the inverse of the estimated model is\napproximated for image rectification, which introduces additional error to the\nsystem. We propose a novel distortion rectification method that uses the\ninverse distortion model directly. The method starts by mapping the distorted\npixels to the rectified image using the inverse distortion model. The resulting\nset of points with subpixel locations are triangulated. The pixel values of the\nrectified image are linearly interpolated based on this triangulation. The\nmethod is applicable to all camera calibration methods that estimate the\ninverse distortion model and performs well across a large range of parameters.","url_abs":"http://arxiv.org/abs/1611.09559v2","url_pdf":"http://arxiv.org/pdf/1611.09559v2.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":"lens-distortion-rectification-using","repo_url":"https://github.com/bbenligiray/lens-distortion-triangulation","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"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}
