In late years ， panorama images have become more popular by the performance enhancement of the digital camera and substantiality of the editing software．We research and develop a virtual space construction system, PasQ, where a virtual space is automatically constructed from multiple panorama images with position (longitude / latitude) and direction information．We can walk through a PasQ space by zooming a panorama image，and replacing an image by another, where relations between neighbor images are automatically computed．In this paper, we propose 4th dimensional extension of a virtual space by giving height and time information to each panorama image．We describe how to walk through also an extended PasQ space: i.e.，how to move upwardly and forwardly，and how to transport to another space with different time zone．In addition，I introduce a grouping concept of panorama images for restricting unexpected walk-through．","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_7_publisher_10":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本データベース学会","subitem_publisher_language":"ja"}]},"item_7_rights_11":{"attribute_name":"出版者URL","attribute_value_mlt":[{"subitem_rights":"http://dbsj.org/journal/dbsj_letters/dbsj_letters_vol_6_no_1_101_104/"}]},"item_7_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright c 2007 日本データベース学会","subitem_rights_language":"ja"}]},"item_7_source_id_12":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1883-1060","subitem_source_identifier_type":"ISSN"}]},"item_7_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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田村, 晃一","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"8299","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"池田, 隼","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"8300","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"國島, 丈生","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"8301","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"横田, 一正","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"8302","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-03-02"}],"displaytype":"detail","filename":"IS-Matsumoto87(2).pdf","filesize":[{"value":"447.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"fulltext","objectType":"fulltext","url":"https://naist.repo.nii.ac.jp/record/4121/files/IS-Matsumoto87(2).pdf"},"version_id":"314c75bf-3b69-4192-85ec-220d03667876"}]},"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":"パノラマ画像の4次元配置による仮想空間の拡張","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"パノラマ画像の4次元配置による仮想空間の拡張","subitem_title_language":"ja"}]},"item_type_id":"7","owner":"4","path":["35"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2018-03-30"},"publish_date":"2018-03-30","publish_status":"0","recid":"4121","relation_version_is_last":true,"title":["パノラマ画像の4次元配置による仮想空間の拡張"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-11-17T02:00:40.083726+00:00"}
