We assume a perspective\ncamera model with unknown focal length and unknown radial distortion. The\nradial distortion is modelled using the division model with one parameter. We\nshow that the solutions to this problem can be found from a univariate\nsix-degree polynomial. This results in a very fast and numerically stable\nsolver.","url_abs":"http://arxiv.org/abs/1805.10705v2","url_pdf":"http://arxiv.org/pdf/1805.10705v2.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":"a-fast-minimal-solver-for-absolute-camera","repo_url":"https://github.com/hamburgerlady/fast_planar_camera_pose","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[{"task_slug":"camera-pose-estimation","task_name":"Camera Pose Estimation"},{"task_slug":"pose-estimation","task_name":"Pose Estimation"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
