In this study, one of the twelve hawks which are owned by The National Museum of Modern Art Tokyo was used as experimental object. The object is metal work by Chokichi Suzuki of the Meiji period. First, the 3D shape of the head of one of the twelve hawks is measured with laser range finder. The defective part of the shape data is complemented plurality of range images. Next, multi-spectral reflection model is developed for rendering the material of the metal work. The reflection model can describe reflection of metal, alloy and inhomogeneous dielectric material. In this paper, we described reflection properties of Oborogin as alloy with the reflection model. Third, An estimation algorithm of spectral reflectance from RGB camera outputs is developed based on statistically analysis of relation of spectral reflectance and camera output. The object material is discriminated with the estimated spectral reflectance. Finally, we rendered CG image of the craft object with estimated material information.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告グラフィクスとCAD（CG）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2014-06-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"2014-CG-155"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":101857,"updated":"2025-01-21T11:01:47.563614+00:00","links":{}}
