Abstract

The invention discloses a WiFi-based indoor positioning method, comprising: selecting a plurality of reference position points indoors, collecting the WiFi signal strength of each WiFi signal source at each reference position point; The WiFi signal strength of the WiFi signal source is subjected to noise reduction processing to obtain the signal strength characteristic value of each reference position point; when positioning, obtain the WiFi signal strength of multiple WiFi signal sources collected at the current position point, and perform noise reduction Process to obtain the signal strength characteristic value of the current position point; compare the signal strength characteristic value of the current position point with the signal strength characteristic value of each reference position point, and set the reference position point with the highest similarity as the current position point. The invention can solve the problems in the prior art that the positioning interference is large, the positioning accuracy is poor, and the equipment needs to be rearranged for public places with different indoor layouts.

Description

technical field [0001] The present invention relates to the technical field of indoor positioning, in particular to a WiFi-based indoor positioning method. Background technique [0002] Satellite positioning technology has penetrated into people's lives, and with RTK (Real-time kinematic, real-time dynamic) and other technologies, the positioning accuracy has been improved to the centimeter level, but in indoor positioning, there are still no signals or great positioning errors The problem. [0003] At this stage, the main commercial indoor positioning methods are Bluetooth positioning and WiFi positioning. The main idea of ​​Bluetooth positioning is to deploy a Bluetooth gateway in the area that needs to be positioned. When a user holding a Bluetooth terminal device (such as a Bluetooth bracelet) enters the Bluetooth signal coverage of the Bluetooth gateway, the Bluetooth gateway can sense the broadcast of the Bluetooth bracelet. Signal, and then measure and calculate the...
