Our approach uses the Projective Grid Space to define virtual three dimensional space, and then the three dimensional scene flow can be estimated by  checking consistency of the optical flows computed for each cameras using constaint by the epipolar geometry. Effects of the proposed method are shown by experimental results of simulation and real images.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"102","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告コンピュータビジョンとイメージメディア（CVIM）"}],"bibliographicPageStart":"97","bibliographicIssueDates":{"bibliographicIssueDate":"2005-05-12","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"38(2005-CVIM-149)","bibliographicVolumeNumber":"2005"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T23:16:41.975712+00:00","updated":"2025-01-22T06:49:01.128897+00:00","id":52353}
