In our previous method we use feature-line matching approach to unify the point clouds obtained by measurement of an artificial building. However, because of matching the feature lines as a silhouette of column,our previous method makes unexpected results from point clouds that contained\nthe column form. In this paper, we propose the column shaft estimation method from a point cloud. The estimated feature lines as a column shaft that isunchangeable line is effective for registration of point clouds. The registration method using this feature lines is able tounify point clouds that contained the column form. As a result, our extended method has improved the column shaftestimation from a point cloud, compared to previous method.","subitem_description_type":"Other"}]},"item_16_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"64065","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KONNO, Tetsuji"}]},{"nameIdentifiers":[{"nameIdentifier":"64066","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KONNO, Kouichi"}]}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"編集：日本情報考古学会　発売：勉誠出版"}]},"item_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1342-4084","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学"}]},"item_16_version_type_27":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"金野, 哲士"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"今野, 晃市"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"jsai-v13n2pp1-9.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jsai-v13n2pp1-9.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/10334/files/jsai-v13n2pp1-9.pdf"},"version_id":"baed457d-c5d4-4b7e-a75d-f1317baf7a93"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"建造物","subitem_subject_scheme":"Other"},{"subitem_subject":"3次元計測","subitem_subject_scheme":"Other"},{"subitem_subject":"点群","subitem_subject_scheme":"Other"},{"subitem_subject":"円柱形状","subitem_subject_scheme":"Other"},{"subitem_subject":"中心軸推定","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"3次元計測点群からの円柱形状認識と中心軸推定―志波城外郭南門復元の試行―","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"3次元計測点群からの円柱形状認識と中心軸推定―志波城外郭南門復元の試行―"}]},"item_type_id":"16","owner":"3","path":["1519"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-01"},"publish_date":"2014-09-01","publish_status":"0","recid":"10334","relation_version_is_last":true,"title":["3次元計測点群からの円柱形状認識と中心軸推定―志波城外郭南門復元の試行―"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:37:13.290849+00:00"}
