1 人で赴くことが一般的になるが，不慮の事故を迅速に発見するために，リアルタイムに作業員の位置をモニタリングする必要がある．既存手法として，Wi-Fi や Bluetooth 等電波を利用するものがあるが，清掃工場では通信設備の需要が乏しく，また広大であることから，測位のためだけに Wi-Fi 基地局や Blueooth のビーコンを設置するコストは負担できない．そこで，我々は磁気に注目している．磁気による屋内測位手法では，インフラ整備は不要でありコスト削減が見込まれる．さらに清掃工場には，帯磁した金属，大型モータや発電機が広範囲にわたって存在しており，各地点で磁気の特異性が観測できるのではと考えた．このような仮定のもと，我々は清掃工場における屋内測位システムの開発を目的とし，現場でのデータ収集と解析を進めている．本稿では，清掃工場内の空間的な測位に対して，気圧を用いてフロアを特定する鉛直方向の推定と，1 フロア中の場所を特定する水平方向の推定の 2 項目について検証した結果を示している．前者は 10 フロアから 1 フロアを推定するタスクとして正解率 0.895 を得ており，後者は，フロアの特定および端末の姿勢が把握された上で，測位誤差の中央値が 9.16[m]
