The mobile camera images are taken from the users viewpoint, and the aerial-view images include the same region. To increase the correspondence accuracy, we generate a virtual top-view image that virtually captures the target region overhead of the user by using the intrinsic parameters of the mobile camera and the inertia (gravity) information. We find corresponding points between the virtual top-view and aerial-view images and estimate a homography matrix that transforms the virtual top-view image into aerial-view image. Finally, the mobile cameras position and orientation are estimated by analyzing the matrix. In some cases, however, it is difficult to obtain a sufficient number of correct corresponding points to estimate the correct homography matrix by capturing only a single virtual top-view image. We solve this problem by stitching virtual top-view images to represent a larger ground region. We experimentally implemented our method on a tablet PC and evaluated its effectiveness.","subitem_description_type":"Abstract"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Information Processing Society of Japan"}]},"item_5_publisher_28":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_publisher":"Information Processing Society of Japan"}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2197/ipsjtcva.6.111","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"一般社団法人 情報処理学会"}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1882-6695","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Toriya, Hisatoshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kitahara, Itaru"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ohta, Yuichi"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-07-02"}],"displaytype":"detail","filename":"IPSJ-TCVA0600026.pdf","filesize":[{"value":"14.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"IPSJ-TCVA0600026","url":"https://tsukuba.repo.nii.ac.jp/record/34027/files/IPSJ-TCVA0600026.pdf"},"version_id":"8dda670d-cc95-4482-aa39-93e58cb1e57c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"mobile camera localization","subitem_subject_scheme":"Other"},{"subitem_subject":"keypoint matching","subitem_subject_scheme":"Other"},{"subitem_subject":"image features","subitem_subject_scheme":"Other"},{"subitem_subject":"GIS","subitem_subject_scheme":"Other"},{"subitem_subject":"aerial-view","subitem_subject_scheme":"Other"},{"subitem_subject":"image stitching","subitem_subject_scheme":"Other"},{"subitem_subject":"mobile camera localization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"keypoint matching","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"image features","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"GIS","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aerial-view","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"image stitching","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Mobile Camera Localization Using Aerial-view Images","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Mobile Camera Localization Using Aerial-view Images"},{"subitem_title":"Mobile Camera Localization Using Aerial-view Images","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["509","3103","3102"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-07-02"},"publish_date":"2015-07-02","publish_status":"0","recid":"34027","relation_version_is_last":true,"title":["Mobile Camera Localization Using Aerial-view Images"],"weko_creator_id":"1","weko_shared_id":21},"updated":"2022-04-27T09:02:46.226938+00:00"}
