The high speed camera was used for determining the shape and the low speed one to measure the motion. The shape of a snowflake and its falling motion are analyzed using continuously photographed image frames. The falling motion of a snowflake is calculated by tracing its position in subsequent frames. Relationships between shape and motion parameters were analyzed. Data indicate that tilt angle and falling direction were perpendicular to each other. It is considered that snowflakes encounter more resistance from air toward the upper direction during their fall.","subitem_description_type":"Abstract"}]},"item_59_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00052948","subitem_identifier_reg_type":"JaLC"}]},"item_59_publisher_19":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"画像電子学会 = The Institute of Image Electronics Engineers of Japan"}]},"item_59_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.11371/iieej.31.345","subitem_relation_type_select":"DOI"}}]},"item_59_relation_30":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://www.jstage.jst.go.jp/browse/iieej/-char/en"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.jstage.jst.go.jp/browse/iieej/-char/en","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://www.iieej.org/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.iieej.org/","subitem_relation_type_select":"URI"}}]},"item_59_rights_25":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © 画像電子学会 The Institute of Image Electronics Engineers of Japan"}]},"item_59_source_id_11":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9831","subitem_source_identifier_type":"ISSN"}]},"item_59_source_id_13":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00041650","subitem_source_identifier_type":"NCID"}]},"item_59_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":"椎名, 徹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"村本, 健一郎"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-12-20"}],"displaytype":"detail","filename":"TE-PR-MURAMOTO-K-345.pdf","filesize":[{"value":"644.8 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"TE-PR-MURAMOTO-K-345.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/46616/files/TE-PR-MURAMOTO-K-345.pdf"},"version_id":"c2523e61-851a-42d1-9dc8-44ef45d9d73b"}]},"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":"連続画像を用いた降雪雪片の落下運動解析システム","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"連続画像を用いた降雪雪片の落下運動解析システム"},{"subitem_title":"Analysis System for Falling Motion of Snowflakes Using Sequential Images","subitem_title_language":"en"}]},"item_type_id":"59","owner":"18","path":["936"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-12-20"},"publish_date":"2018-12-20","publish_status":"0","recid":"46616","relation_version_is_last":true,"title":["連続画像を用いた降雪雪片の落下運動解析システム"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T16:42:15.780828+00:00"}
