Application Number: JP,2022-140874
Category (FI): G16Y20/10,G01S5/02@Z
Stage: PROBLEM TO BE SOLVED: To provide a position estimation system for accurately estimating a position of a wireless terminal.SOLUTION: A position estimation system includes: a plurality of wireless terminals Cn with sensors (n: a natural number of two or greater) located at pre-known positions so as to acquire sensor information measured by one or more sensors; a wireless terminal X with a sensor located at an unknown position so as to acquire the sensor information measured by the one or more sensors; and a position estimation device for estimating a position of the wireless terminal X. The position estimation device estimates the position of the wireless terminal X based on the sensor information received from the wireless terminal X and reception signal information to be obtained by receiving the sensor information, and environment information at the point of time when the sensor information is received from the wireless terminal X by using position information of the wireless terminal Cn, the sensor information received from the wireless terminal Cn and the reception signal information to be obtained by receiving the sensor information, and the environment information at the point of time when the sensor information is received from the wireless terminal Cn.SELECTED DRAWING: Figure 1 (Grant)
