Abstract

The invention relates to the technical field of a communication process, and particularly to a positioning method, mobile terminal and control based on visual light sources. Specifically: a visual light source controller obtains geographic position attribute information of a position where the visual light source array locates; the visual light source controller determines visual light source array pattern corresponding to the obtained geographic position attribute information in accordance with a correspondence between the geographic position attribute information of the position where the visual light source array locates and the visual light source array pattern, wherein, the visual light source array pattern refers to coding information consisting of identification information for identifying lighting status corresponding to each visual light source in visual light source array, the visual light source controller controls lighting status of each visual light source included in the visual light source array according to determined visual light source pattern, and in this case, complexity in positioning is reduced, and problem of single positioning method is solved.

Description

technical field [0001] The invention relates to the technical field of communication processing, in particular to a positioning method based on a visible light source, a mobile terminal and a controller. Background technique [0002] Visible light communication technology is a new wireless communication technology that has emerged in recent years. When the light source is illuminating, it integrates the communication function, so that the light source can realize both the lighting function and the communication function. Compared with traditional radio frequency communication technology and other wireless optical communication technologies, visible light communication technology has the advantages of high transmission power, no occupation of radio frequency spectrum, no electromagnetic interference and no electromagnetic radiation, and energy saving. Therefore, visible light communication technology has become increasingly important. [0003] At present, the application res...
