For the parameter estimation, we first measure the real object several times with a number of cameras, and then, fit them to the reflection model. Since the reflection model is usually complicated with many parameters, the fitting process is not easy and unstable. In addition, the shape of the target object is usually flat and uniform for such purpose, whereas our target is 3D object with non-uniform texture, therefore, parameter estimation becomes more difficult. For solution, we propose a bundle adjustment approach for better camera calibration and new optimization method based on Lafortune model.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"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":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2010-05-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"8","bibliographicVolumeNumber":"2010-CVIM-172"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":69554,"links":{}}
