this paper, we propose a smartphone positioning method based on magnetic field marker. The spinning magnet generates characteristic magnetic field. Magnetometer that equipped in smartphone measure the magnetic field, and estimate the relative location of smartphone and marker Distance between smartphone and marker is calculated by magnetic intensit. Angle is calculated according to the angle of magnetic stick and the timing of extremum of magnetic intensity. In our experiment, when the distance of smartphone and marker is less 2m, the average error of distance estimation is 13cm. When the distance of smartphone and marker is less 1.4m, the average of distance estimation error is 4cm. In terms of angular accuracy, average error is 24 degree, and the standard deviation is 29 degree.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"149","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"138","bibliographicIssueDates":{"bibliographicIssueDate":"2018-01-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"59"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":185364,"links":{}}
