We leverage collected RSS measurements of Wi-Fi beacons with GPS locations outside buildings by crowd-sensing participants. Using the information, we firstly estimate virtual AP locations named “Tx-Tiles” on the building walls. Simultaneously, we collect RSS measurements inside each building without GPS locations and apply a 3-D Multi-dimensional Scaling (MDS) technique to estimate the relative coordinates of APs in the building. We utilize the Tx-Tiles as location anchors in the MDS localization and obtain the physical 3-D coordinates in the building. Our method does not require any tagging by participants (no human intervention) and does not need any indoor location anchors for 3-D AP localization.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1340","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1328","bibliographicIssueDates":{"bibliographicIssueDate":"2021-05-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"5","bibliographicVolumeNumber":"62"}]},"relation_version_is_last":true,"item_2_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20729/00211106","subitem_identifier_reg_type":"JaLC"}]},"weko_creator_id":"44499"},"id":211212,"links":{}}
