Although any object having any position and pose in the 3-dimensional space has 6 degrees of freedom, our subject becomes the recovery problem of 2 rotational angles of a circle under such a supposition. First, we certify that an image of a circle is an ellipse either by perspective projection or by orthographic projection. Second, the equations for calculating the normal vector of a circle are derived using an image which is supposed to be projected orthographically. Then 2 rotational angles and the radius of a circle are calculated using the normal vector. Last, several experiments are simulated and the recovering accuracy is examined.","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"<特集>高木教典教授・井上宏教授・水越敏行教授定年退職記念","subitem_description_type":"Other"}]},"item_10_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"23048","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Fukada, Youji"}]}]},"item_10_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"関西大学"}]},"item_10_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10484636","subitem_source_identifier_type":"NCID"}]},"item_10_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1341156X","subitem_source_identifier_type":"ISSN"}]},"item_10_version_type_17":{"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":"深田, 陽司"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-05-22"}],"displaytype":"detail","filename":"KU-1100-20040325-10.pdf","filesize":[{"value":"901.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KU-1100-20040325-10.pdf","url":"https://kansai-u.repo.nii.ac.jp/record/10875/files/KU-1100-20040325-10.pdf"},"version_id":"8f3174e8-fc96-4338-a029-af49baecc0bb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"関西大学","subitem_subject_scheme":"Other"},{"subitem_subject":"Kansai University","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":"正射投影を仮定した単眼視からの2回転角の算出","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"正射投影を仮定した単眼視からの2回転角の算出"}]},"item_type_id":"10","owner":"1","path":["1555"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-02-08"},"publish_date":"2018-02-08","publish_status":"0","recid":"10875","relation_version_is_last":true,"title":["正射投影を仮定した単眼視からの2回転角の算出"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-05-17T02:04:20.807190+00:00"}
