In this study, we present a new device-free and privacy preserving indoor positioning method using infrared (IR) cameras and retroreflectors. The proposed method employs IR cameras equipped with IR LEDs to capture retroreflections from markers attached to walls in the environment, and detects a person who passes between the camera and a marker by observing the occlusion. Because our method employs occlusion of markers, it can track a person without attaching tags to the person. In addition, to preserve privacy of the person, our camera device enables us to filter out visible light and thus the appearance of the person is not recorded. Our evaluation in real environments showed that our method achieved an average positioning error of about 0.3m meters.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"137","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"124","bibliographicIssueDates":{"bibliographicIssueDate":"2018-01-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"59"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
