3D shape scanning technique becomes popular . Structured light systems (SLS) based active 3D scanning systems are widely used in the air and also promising to apply underwater environment. When SLS is used in the air, the stereo correspondences can be efficiently retrieved by epipolar constraint. However, in the underwater environment, the camera and projector are usually set in special housings and refraction occurs at the interfaces between water / glass and glass / airIn this paper, we propose an efficient technique to calibrate the underwater SLS systems as well as robust 3D shape acquisition technique. In order to avoid the calculation complexity, we approximate the system with central projection model. Although such an approximation produces an inevitable errors in the system, such errors are eliminated by the grid based SLS technique followed by a bundle adjustment algorithm. We tested our method with a real underwater SLS, consisting of custom-made laser pattern projector and underwater housings, showing the validity of our method. And also, we have treaedt fast objects like fish, so we made an auto-capture system. In fact, we could capture many frames of fish.","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":"2017-03-02","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"2017-CVIM-206"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":178331,"updated":"2025-01-20T05:09:38.497138+00:00","links":{},"created":"2025-01-19T00:47:41.204821+00:00"}
