Problems solved by technology

[0008] In addition, WiFi transceivers can only cover areas within a radius of 90 meters, and due to the influence of walls and obstacles, it will cause a series of problems such as multipath attenuation, absorption, and shading, and there will be coverage dead spots in elevators, stairs, etc. Thus affecting its accuracy; WiFi can only locate a range of mobile devices, and cannot describe its trajectory

Embodiment Construction

[0024] A kind of indoor positioning method of AR glasses through WIFI and G-sensor, see figure 1 with figure 2 , including a background server (positioning server) connected to a network server and a local area network, the background server contains an indoor building structure diagram, includes a distribution network diagram of a wireless switch (AP, router) formed around the indoor building structure, and according to the wireless switch The coordinate map formed by the distribution of network signal strength in the indoor building structure, because the accuracy of WiFi (wireless networking technology) is about 1 meter to 15 meters, it is necessary to set several AP fixed points in the indoor building structure first, the system The coverage area collects the location information and signal strength of several AP fixed points set up to form a location database. It needs to collect the location information and signal strength before it can be used for positioning; the posi...

Abstract

The invention relates to a method for accurately positioning AR glasses indoors in virtue of WIFI and a G-sensor. A server is provided in a design scheme and stores an indoor building structural drawing, a wireless switch distributed network graph formed in view of indoor building structure, and a coordinate graph formed in the indoor building structure according to the wireless switch distributed network signal intensity. The AR glasses are accurately positioned in a building according to a data transmission time difference between the AR glasses and different switches and the three-dimensional information of the G-sensor. The method solves a defect of indoor positioning just using WiFi technology and prevents coverage blind angles of the WIFI. The G-sensor may continuously manifest the motion locus of a mobile device, prevents coverage blind angles, and can be adapted to complex environments of large buildings. The method, by means of the advantages of the two technologies and in combination with a motion locus algorithm and building structure, achieves high indoor positional accuracy within 1 meter and indoor and outdoor seamless positioning.

Description

technical field [0001] The invention relates to the field of wireless positioning, in particular to an indoor precise positioning method for AR glasses through WIFI and G-sensor. Background technique [0002] AR glasses is a sci-fi product first created by Google, and it is also a product with avant-garde technology. Wearing it, you can experience the future functions used by handsome male and female protagonists in sci-fi movies. AR glasses The use scenarios are divided into indoor and outdoor. Outdoors, the combination of GPS and AGPS is used for navigation to ensure the accuracy of navigation. There is currently no good solution for indoor environments. This design is aimed at the navigation needs of AR glasses for indoor environments. research and development. [0003] With the rapid increase of data services and multimedia services, people's demand for positioning and navigation is increasing, especially in complex indoor environments, such as airport halls, exhibition...
