Title:
POSITIONING METHOD, PROGRAM, AND POSITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/259665
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to improve the positioning accuracy of a beacon terminal. This positioning method includes a step for acquiring RSSIs of beacon signals respective to a plurality of scanners (4) which receive beacon signals. Furthermore, the positioning method includes a determination step in which if the difference between a RSSI instantaneous value at a prescribed point in time of a scanner (4) of interest from among the plurality of scanners (4), and the RSSI average value during a prescribed period of a prescribed target scanner from among the plurality of scanners (4) is a value that falls outside of a prescribed range, the RSSI instantaneous value at the prescribed point in time of the scanner (4) of interest is determined to be an abnormal value. Moreover, the positioning method includes a step for finding the position of the beacon terminal (5) on the basis of two or more RSSIs from which the RSSI determined to be an abnormal value in the determination step has been removed.
