Document Type and Number:
WIPO Patent Application WO/2018/098850
Kind Code:
A1
Abstract:
A multi-sensor fusion-based indoor navigation device and method, the method comprising: building a current indoor magnetic map; measuring basic information data of a current indoor position in real time, the basic information data comprising: an air pressure difference ΔP of a current floor position relative to the ground, a magnetic induction intensity time sequence and a magnetic field gradient matrix time sequence on a walking route between a position at the current time and the position at the previous time, a time sequence value of acceleration in three directions XYZ of when a human body or an automated guided vehicle (AGV) advances on the walking route, a time sequence value of angular velocity in the three directions XYZ of when the human body or AGV advances on the walking route, and barrier distance in an axial direction X of when the human body or AGV advances on the walking route. Fusing the basic information data, positioning a real time position and performing straight line sectional navigation. The present invention has accurate positioning and accurate navigation.
