Indoor positioning method

Abstract

The invention provides an indoor positioning method, and relates to a wireless communication network technology for network management. A method combining positioning based on a WiFi fingerprint and visual positioning based on a label is adopted. The method comprises the following steps: firstly, acquiring a WiFi positioning range and a WiFi positioning coordinate by using a WiFi position fingerprint positioning algorithm; secondly, acquiring a visual positioning coordinate according to feature matching and visual positioning of a tested image; lastly, combining WiFi position fingerprint positioning with visual positioning to realize high-accuracy indoor positioning. By adopting method, the defects that the conventional WiFi fingerprint positioning technology has low accuracy and the conventional single visual positioning method technology is not suitable for indoor positioning are overcome.

Description

technical field

[0001] The technical solution of the present invention relates to the wireless communication network technology for the purpose of network management, specifically an indoor positioning method. Background technique

[0002] Indoor positioning refers to the realization of position positioning in the indoor environment. It mainly adopts wireless communication, base station positioning, inertial navigation positioning and other technologies to form an indoor position positioning system, so as to realize the position monitoring of people and objects in the indoor space. Due to the complex and changeable indoor environment and the inability to receive GPS (Global Positioning System) signals, it is currently difficult to locate indoors. When satellite positioning cannot be used in the indoor environment, indoor positioning technology is used as an auxiliary positioning of satellite positioning to solve the problem that the satellite signal is weak when it reaches t...
