A TL camera is characterized by orthonormal projection rather than conventional central projection. In the first case, a lattice with a 2mm\nwidth drawn with CAD software is used. The estimated measurement precision of image coordinates is 0.7 pixels (5μm) and the residuals with 5 to 10 μm amplitude appeared periodic, which may be attributable to printer's positioning precision. And lens distortions of 10-15μm in magnitude are found in the fringe of the image plane. In the second case, to evade absolute object point coordinates of targets, a 3D field of circles of 2mm in diameter is exposed in a convergent way and their image coordinates are bundle adjusted. When no interior orientation parameters are added, obtained precision of image coordinates is 0.44 pixels. And when a K1 term from Brown's model is added as an additional parameter, the precision is improved to 0.40 pixels.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告オーディオビジュアル複合情報処理（AVM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2013-07-12","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2013-AVM-81"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
