Abstract

The invention discloses a positioning method, device and system based on visible light communication, and aims at solving the problems that a present mobile positioning method is relatively low in positioning accuracy and narrow in suitable range. The method comprises that a mobile terminal receives a light signal emitted by a visible light source, and the light signal carries an identification for representing the position of the visible light source; the received light signal is parsed by utilizing a preset algorithm, and the identification carried in the light signal is determined; and geographic position information corresponding to the identification is searched from, and serves a positioning result of the mobile terminal.

Description

technical field [0001] The present application relates to the technical field of visible light communication, and in particular to a positioning method, device and system based on visible light communication. Background technique [0002] With the continuous development of mobile technology, the functions of mobile terminals become more and more abundant, and the mobile positioning function provided by the mobile terminal brings great convenience to the daily use of users. [0003] Current mobile positioning methods mainly include: Global Positioning System (Global Positioning System, GPS) positioning and Wireless-Fidelity (Wi-Fi) positioning. [0004] The basic principle of GPS positioning is to measure the distance between the known satellite and the user's receiver, and then integrate the data of multiple satellites to know the specific position of the receiver. However, the GPS positioning system has errors such as instability, high power consumption, weak signal, poor ...
