Positioning device, moving body stop position detection system, control circuit, and storage medium

Abstract

The present invention provides a positioning device for achieving high-precision one-dimensional positioning, comprising: a travel direction distance conversion unit (26) that converts the distances between a plurality of fixed ranging devices and a moving body into travel direction distances using positioning assistance information, wherein the positioning assistance information includes position information of the fixed ranging devices and position information of the moving body; an outlier extraction unit (27) that extracts information of distances determined to be outliers based on information regarding the dispersion state of the plurality of travel direction distances; an outlier removal unit (28) that removes outliers from the plurality of distances; and a positioning calculation unit (29) that calculates travel direction position information based on the distances after removing outliers.
