位置情報を利用したサービスが多くある中で，屋内の位置推定精度の向上が課題となっている．本研究では，モバイル端末をビーコンとして使い，人の複数存在する環境下で位置推定の精度を向上させる手法について提案する．動的遮蔽物を考慮して距離を算出し，位置推定を行うことで推定精度を向上させる．実空間における実験で，ビーコンが3つ，モバイル端末を持つ人が3人設置してある空間に適用した結果，位置推定精度が向上した．We can use a lot of services using positioning system. Accordingly, there is a problem about improving indoor positioning accuracy.  In this research, by using the mobile terminal (smartphone and tablet) as a kind of beacon. We propose a method that can estimate positions with higher precision in a place with many people than previous ones. We attempt to improve the positioning accuracy by calculating distances between each device with RSSI considering movable obstructions. We experimented in a real environment and applied a proposed method to an environment where we set three BLE beacons and three humans who have mobile devices. As a result, compared with previous methods, the positioning accuracy improved, which showed the superiority of this method.application/pd
