The number of trees identified by each method (Urban Tree Detection and DeepForest) differed greatly.  In Urban Tree Detection, the gap between the crowns of adjacent trees was determined to be the top of trees in many cases, and tree individuals were not properly identified. In the DeepForest, the number of trees identified differed depending on the patch (tree crown) size setting, and smaller patch size settings identified relatively more appropriate tree individuals than other methods.  Following these results, it was determined that individual tree identification using AI is difficult at present, and among the tested methods, DeepForest is the method with the most potential, including future expandability.  For practical individual identification in the future, it was considered important to 1) divide the area to be analyzed into areas of similar types as much as possible, 2) improve learning accuracy by acquiring training data in the forest to be analyzed, and 3) create a program that can analyze multiple images and additional information.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_11_identifier_registration":{"attribute_name":"identifier_registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15045/0002000413","subitem_identifier_reg_type":"JaLC"}]},"item_11_publisher_13":{"attribute_name":"item_11_publisher_13","attribute_value_mlt":[{"subitem_publisher":"玉川大学","subitem_publisher_language":"ja"}]},"item_11_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1341-8645","subitem_source_identifier_type":"PISSN"}]},"item_11_version_type_9":{"attribute_name":"出版タイプ","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":"友常, 満利","creatorNameLang":"ja"}],"familyNames":[{"familyName":"友常","familyNameLang":"ja"}],"givenNames":[{"givenName":"満利","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"Contreras, Luis","creatorNameLang":"en"}],"familyNames":[{"familyName":"Contreras","familyNameLang":"en"}],"givenNames":[{"givenName":"Luis","givenNameLang":"en"}]},{"creatorNames":[{"creatorName":"小酒井, 正和","creatorNameLang":"ja"}],"familyNames":[{"familyName":"小酒井","familyNameLang":"ja"}],"givenNames":[{"givenName":"正和","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"関川, 清広","creatorNameLang":"ja"}],"familyNames":[{"familyName":"関川","familyNameLang":"ja"}],"givenNames":[{"givenName":"清広","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"武藤, ゆみ子","creatorNameLang":"ja"}],"familyNames":[{"familyName":"武藤","familyNameLang":"ja"}],"givenNames":[{"givenName":"ゆみ子","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"岡田, 浩之","creatorNameLang":"ja"}],"familyNames":[{"familyName":"岡田","familyNameLang":"ja"}],"givenNames":[{"givenName":"浩之","givenNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"11_2024_95-100.pdf","filesize":[{"value":"2.0 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://tamagawa.repo.nii.ac.jp/record/2000413/files/11_2024_95-100.pdf"},"version_id":"ace4aa9c-ed0b-49aa-9b92-8ab73233c427"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"人工知能","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ドローン","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"樹木","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"AIと高解像度ドローン空撮画像を用いた樹木個体の識別 : 様々な樹種が混交した森林の構造解析を目指して","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"AIと高解像度ドローン空撮画像を用いた樹木個体の識別 : 様々な樹種が混交した森林の構造解析を目指して","subitem_title_language":"ja"},{"subitem_title":"Identify individual trees using AI in high-resolution aerial images taken by a drone : Aiming for structural analysis of forests with a mixture of various tree species","subitem_title_language":"en"}]},"item_type_id":"11","owner":"5","path":["1744338237731"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2025-04-14"},"publish_date":"2025-04-14","publish_status":"0","recid":"2000413","relation_version_is_last":true,"title":["AIと高解像度ドローン空撮画像を用いた樹木個体の識別 : 様々な樹種が混交した森林の構造解析を目指して"],"weko_creator_id":"5","weko_shared_id":-1},"updated":"2025-04-14T03:39:39.061409+00:00"}
