In the conventional approaches to the problem, primarily target scenes are limited to the in-door scenes, that is, a small object is taken from relatively far-distant cameras, because this situation significantly reduces difficulty of the problem. On the other hand, when we think of recovering entire building shape from images taken at the near disntance, the problem gets very difficult because each image contains only small part of the whole structure, which leads to the point that the feature point correspondence informations gets very poor. This paper describes a recovery method for this kind of situation. Experiments on real building recovery shows the efficiency of our methods.","subitem_description_type":"Abstract"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会"}]},"item_3_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"110002674665","subitem_relation_type_select":"NAID"}}]},"item_3_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"情報処理学会"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ipsj.or.jp/","subitem_relation_type_select":"URI"}}]},"item_3_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"ここに掲載した著作物の利用に関する注意：本著作物の著作権は（社）情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。"},{"subitem_rights":"The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
