[Methods] The object to be measured, a goniometer, was\nfixed on box at a 120° angle to be shot from a distance of 1 m, 2 m, and 3 m at four shooting angles from the object:\n0°, 10°, 20°, and 30°. Two smartphones were used for each shot, and three consecutive shots were taken with each\nphone. The goniometer angle was calculated for all images using the app. The reliability of the angle measured from\ndifferent shooting distances at each shooting angle and the difference between the measured values with different\nshooting angles were calculated. [Results] The reliability of measurements was high up to a shooting distance of 2 m.\n200\nAdditionally, the measured goniometer angle reduced significantly as the imaging angle increased. [Discussion] The\ndifference in angular measures increased as the shooting distance was increased in small increments; consequently,\nthe reliability decreased. Furthermore, as the shooting angle increased, depth was created at the index points, which\nmay have affected measurement values. Therefore, angular measurements using the app are highly reliable when the\ntarget is within 2 m and in line with the camera.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18933/00000456","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"了德寺大学"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12217741","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1881-9796","subitem_source_identifier_type":"EISSN"}]},"item_10002_version_type_20":{"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":"兎澤, 良輔","creatorNameLang":"ja"},{"creatorName":"トザワ, リョウスケ","creatorNameLang":"ja-Kana"},{"creatorName":"Tozawa, Ryosuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川崎, 翼","creatorNameLang":"ja"},{"creatorName":"カワサキ, ツバサ","creatorNameLang":"ja-Kana"},{"creatorName":"Kawasaki, Tsubasa","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-04-14"}],"displaytype":"detail","filename":"スマートフォンアプリケーションを用いた角度計測において撮影距離と撮影角度が信頼性および測定値に与える影響.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"スマートフォンアプリケーションを用いた角度計測において 撮影距離と撮影角度が信頼性および測定値に与える影響","url":"https://ryotokuji-u.repo.nii.ac.jp/record/516/files/スマートフォンアプリケーションを用いた角度計測において撮影距離と撮影角度が信頼性および測定値に与える影響.pdf"},"version_id":"1a386fb4-4c35-496a-9c88-e95cbc39179a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"スマートフォン","subitem_subject_scheme":"Other"},{"subitem_subject":"アプリケーション","subitem_subject_scheme":"Other"},{"subitem_subject":"撮影距離","subitem_subject_scheme":"Other"},{"subitem_subject":"撮影角度","subitem_subject_scheme":"Other"},{"subitem_subject":"信頼性","subitem_subject_scheme":"Other"},{"subitem_subject":"smartphone","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"application","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"shooting distance","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"shooting angle","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"reliability","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":"スマートフォンアプリケーションを用いた角度計測において 撮影距離と撮影角度が信頼性および測定値に与える影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"スマートフォンアプリケーションを用いた角度計測において 撮影距離と撮影角度が信頼性および測定値に与える影響","subitem_title_language":"ja"},{"subitem_title":"Effects of shooting distance and shooting angle on the reliability of measurement values in angle measurement using a smartphone application","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"8","path":["25"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-04-15"},"publish_date":"2022-04-15","publish_status":"0","recid":"516","relation_version_is_last":true,"title":["スマートフォンアプリケーションを用いた角度計測において 撮影距離と撮影角度が信頼性および測定値に与える影響"],"weko_creator_id":"8","weko_shared_id":-1},"updated":"2023-10-13T06:40:18.508884+00:00"}
