Thus, the study makes it possible to detect objective scene from video images taken with RGBD-camera for learning martial arts techniques by video observation. Next, in order to enable motion observation from an arbitrary angle, we developed a basic method for generating a 3D model of a player by estimating the three dimensional coordinates of the player's joints from video images. We also developed a method to generate bird's-eye view images of foot positions on a floor by the homography transformation for the observation of players' footwork.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(C);  研究期間：2015～2017;   課題番号：15K01102;   研究分野：教育工学;   科研費の分科・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-15K01102/"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者/連携研究者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"TANAKA, Kazumoto"},{"subitem_text_language":"en","subitem_text_value":"OCHI, Youji"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学工学部; 教授"},{"subitem_text_value":"近畿大学理工学部; 准教授"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"},{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田中, 一基"},{"creatorName":"タナカ, カズモト","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"越智, 洋司"},{"creatorName":"オチ, ヨウジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-11-22"}],"displaytype":"detail","filename":"15K01102seika.pdf","filesize":[{"value":"706.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"15K01102seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/19788/files/15K01102seika.pdf"},"version_id":"20de5262-f9c2-49e2-a6c2-eab2ceecb7ee"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"スポーツ","subitem_subject_scheme":"Other"},{"subitem_subject":"振り返り学習","subitem_subject_scheme":"Other"},{"subitem_subject":"ビデオ映像","subitem_subject_scheme":"Other"},{"subitem_subject":"シーン検出","subitem_subject_scheme":"Other"},{"subitem_subject":"3D点群","subitem_subject_scheme":"Other"},{"subitem_subject":"ポイントマッチング","subitem_subject_scheme":"Other"},{"subitem_subject":"ホモグラフィ変換","subitem_subject_scheme":"Other"},{"subitem_subject":"三次元復元","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"３D点群処理に基づく対人競技の振り返り学習支援システムの開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"３D点群処理に基づく対人競技の振り返り学習支援システムの開発"},{"subitem_title":"Development of a support system for learning martial arts techniques by video observation based on 3D point cloud processing","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4459"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-11-22"},"publish_date":"2018-11-22","publish_status":"0","recid":"19788","relation_version_is_last":true,"title":["３D点群処理に基づく対人競技の振り返り学習支援システムの開発"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T21:34:09.687671+00:00"}
