Title:
POSITION CORRECTION DEVICE, POSITION CORRECTION METHOD, AND POSITION CORRECTION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/042570
Kind Code:
A1
Abstract:
When a plurality of wireless terminals are arranged in a two-dimensional grid, the position of each wireless terminal is estimated as an estimated position, and each estimated position can contain an error, a position correction device (100) corrects each estimated position. The position correction device (100) also comprises an installation interval estimation unit (110). The installation interval estimation unit (110) performs clustering for the plurality of wireless terminals so that the distance between every two adjacent clusters satisfies a first installation interval condition, on the basis of a coordinate component in the horizontal axis direction among coordinate components of each estimated position, and performs clustering for the plurality of wireless terminals so that the distance between every two adjacent clusters satisfies a second installation interval condition, on the basis of a coordinate component in the vertical axis direction among the coordinate components of each estimated position.
