In this study, we examined the availability of UAV-based monitoring for egrets. The survey was conducted in Lake Izunuma (369 ha), and a total of 7,852 images were obtained using UAV in September 2018. Using the UAV imagery, the ability to discriminate egrets was examined. As a result, egrets were confirmed in 855 images, and UAV was considered available for monitoring egrets in lakes. To improve the efficiency of UAV monitoring, the availability of image analysis methods using binarization processing was evaluated. As a result, it was found that the binarization process is useful for screening UAV images. However it is difficult to extract only egrets, and further consideration of the method is necessary. UAV and image processing technologies were able to gather new insights of egrets. It is recommended that consider better protocols for UAV ecosystem monitoring.","subitem_description_type":"Abstract"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"23718","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SUZUKI, Toru"}]},{"nameIdentifiers":[{"nameIdentifier":"23719","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TAKAHASHI, Yusuke"}]},{"nameIdentifiers":[{"nameIdentifier":"23720","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SHIMADA, Tetsuo"}]}]},"item_2_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"応用生態工学会"}]},"item_2_relation_11":{"attribute_name":"ISBN","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"1344-3755","subitem_relation_type_select":"ISBN"}}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3825/ece.19-00019","subitem_relation_type_select":"DOI"}}]},"item_2_version_type_19":{"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":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"鈴木, 透","creatorNameLang":""}],"familyNames":[{"familyNameLang":""}],"givenNames":[{"givenNameLang":""}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"高橋, 佑亮"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"嶋田, 哲郎"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-03-20"}],"displaytype":"detail","filename":"R-2022-255_suzuki.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"R-2022-255_suzuki.pdf","url":"https://rakuno.repo.nii.ac.jp/record/7193/files/R-2022-255_suzuki.pdf"},"version_id":"b32725ce-325b-4c02-8356-7cb5ae8b4aa5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"image processing","subitem_subject_scheme":"Other"},{"subitem_subject":"egrets","subitem_subject_scheme":"Other"},{"subitem_subject":"monitoring","subitem_subject_scheme":"Other"},{"subitem_subject":"UAV","subitem_subject_scheme":"Other"},{"subitem_subject":"image processing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"egrets","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"monitoring","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"UAV","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"伊豆沼の湖沼を利用するサギ類のモニタリングにおける UAV の利用可能性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"伊豆沼の湖沼を利用するサギ類のモニタリングにおける UAV の利用可能性"}]},"item_type_id":"2","owner":"3","path":["24"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-03-20"},"publish_date":"2023-03-20","publish_status":"0","recid":"7193","relation_version_is_last":true,"title":["伊豆沼の湖沼を利用するサギ類のモニタリングにおける UAV の利用可能性"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-08-31T01:10:25.853410+00:00"}
