The improvement of precision of the shapes is achieved by minimizing “gaps” between overlapping shapes that remains after registration algorithms are performed. To use projector-camera system for 3D acquisition, we must calibrate the system in advance. Then, we can measure 3D shapes using the calibrated parameters. Noise, lens distortions, or quantization errors can cause calibration errors, which often causes distortions of the reconstructed shapes. In general, error-free calibration is very difficult. So, even if we capture multiple shape data from an object and register all the shapes, there still remains errors between the shapes. In this paper, we re-estimate the extrinsic parameters between the camera and the projector and the focal length of the camera by minimizing the registration errors at the overlapping area of multiple shapes and the errors of epipolar constraints. The process improves the accuracies of the 3D measurement and corrects the rigid transformation parameters of the registrations of the shapes.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"27","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンピュータビジョンとイメージメディア（CVIM）"}],"bibliographicPageStart":"12","bibliographicIssueDates":{"bibliographicIssueDate":"2008-11-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"1"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"updated":"2025-01-22T23:04:46.952320+00:00","links":{}}
