The operation of the UAV for the method flown in a vertical direction, and few images could be taken from different altitudes.  Therefore, the UAV can be operated more easily than general photogrammetric method.  The developed method includes original relative orientation procedure which can be applied to vertical direction images.  In addition, a final orientation which can perform absolute orientation for every parameter and calculate 3D coordinates of all measurement points simultaneously was included.  In order to observe performance evaluation of the method, the checking accuracy of the measurement was performed using UAV test site by Japan Society for Photogrammetry and Remote Sensing.  The UAV was operated in the test site, and the 5 vertical images were taken from 70-90m altitude respectively.  Therefore, 3D coordinates of measurement points were calculated.  As a result, the plane and height accuracy was ±0.093m and ±0.166m respectively.  These values were of higher accuracy than the results of the usual photogrammetric software.  Consequently, the developed method can be 3D measured efficiently, and it is expected that the method will become a useful tool in the field of construction, disaster and any surveying.","subitem_description_type":"Other"}]},"item_1_description_13":{"attribute_name":"レポート・講演番号","attribute_value_mlt":[{"subitem_description":"E","subitem_description_type":"Other"}]},"item_1_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"1","subitem_description_type":"Other"}]},"item_1_description_2":{"attribute_name":"ページ属性","attribute_value_mlt":[{"subitem_description":"P","subitem_description_type":"Other"}]},"item_1_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_1_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00164184","subitem_source_identifier_type":"NCID"}]},"item_1_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"東京農業大学地域環境科学部造園科学科"},{"subitem_text_value":"東京農業大学大学院農学研究科造園学専攻"}]},"item_1_text_7":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Landscape Architecture Science, Faculty of Regional Environment Science, Tokyo University of Agriculture"},{"subitem_text_language":"en","subitem_text_value":"Department of Landscape Architecture, Graduate School of Agriculture, Tokyo University of Agriculture"}]},"item_1_title_3":{"attribute_name":"論文名よみ","attribute_value_mlt":[{"subitem_title":"UAV（ドローン）　ニ　ヨル　スイチョク　ガゾウ　ヲ　モチイタ　シャシン　ソクリョウ　シュホウ　ノ　カイハツ"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"國井, 洋一"},{"creatorName":"クニイ, ヨウイチ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3977","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"熊崎, 理仁"},{"creatorName":"クマザキ, リヒト","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3978","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kunii, Yoichi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"3979","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kumazaki, Rihito","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"3980","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-10-31"}],"displaytype":"detail","filename":"6302_057.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"63_57","url":"https://nodai.repo.nii.ac.jp/record/752/files/6302_057.pdf"},"version_id":"6fdcc691-7965-462d-a42f-37f3d32a67f0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"UAV（ドローン）","subitem_subject_scheme":"Other"},{"subitem_subject":"写真測量","subitem_subject_scheme":"Other"},{"subitem_subject":"垂直画像","subitem_subject_scheme":"Other"},{"subitem_subject":"精度検証","subitem_subject_scheme":"Other"},{"subitem_subject":"Unmanned Aerial Vehicle","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"photogrammetry","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"vertical image","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"checking accuracy","subitem_subject_language":"en","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"UAV（ドローン）による垂直画像を用いた写真測量手法の開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"UAV（ドローン）による垂直画像を用いた写真測量手法の開発"},{"subitem_title":"Development of Photogrammetric Method Using Vertical Image by UAV","subitem_title_language":"en"}]},"item_type_id":"1","owner":"3","path":["178"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-10-31"},"publish_date":"2018-10-31","publish_status":"0","recid":"752","relation_version_is_last":true,"title":["UAV（ドローン）による垂直画像を用いた写真測量手法の開発"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-19T07:44:31.813963+00:00"}
