Title:
METHOD AND SYSTEM FOR ESTIMATING MOVEMENT DIRECTION USING WPS
Document Type and Number:
WIPO Patent Application WO/2016/122019
Kind Code:
A1
Abstract:
The present invention relates to a method and system for estimating a movement direction using a Wi-Fi positioning system (WPS) and, more specifically, to a method and system for estimating the movement direction of a pedestrian in an environment in which a direction calculation is difficult due to geomagnetic contamination. The system for estimating a movement direction using a WPS, according to the present invention, corresponds to a method of performing a movement direction estimation using the WPS. The method comprises the steps of: (a) performing WPS positioning for a pedestrian and setting a movement direction by a plurality of positioning points N; (b) calculating the movement direction at a PDR, when a rotation of a gyro sensor occurs; and (c) synthesizing a WPS positioning point and a PDR positioning point and calculating the movement direction, when a new WPS positioning point and PDR positioning point exist.
