The present invention relates to the field of communication processing technologies, and in particular, to a positioning method based on a visible light source, a mobile terminal, and a controller. Specifically, the method includes: acquiring, by a visible light source controller, geographical position attribute information of a position at which a visible light source array is located; determining, by the visible light source controller according to a preset correspondence between geographical position attribute information of a position at which a visible light source array is located and a visible light source array pattern, a visible light source array pattern corresponding to the acquired geographical position attribute information, where the visible light source array pattern refers to coding information formed by identification information that is separately used to identify a luminance state corresponding to each visible light source included in the visible light source array; and controlling, by the visible light source controller according to the determined visible light source array pattern, the luminance state of each visible light source included in the visible light source array. In this way, complexity of a positioning process is reduced, and a problem that a positioning method is relatively onefold is resolved.
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. While the light source illuminates, it incorporates a communication function, so that the light source can realize both lighting and communication functions. 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 radio spectrum occupation, no electromagnetic interference and no electromagnetic radiation, and energy saving. Therefore, visible light communication technology has become increasingly important. [0003] At present, the application research of visible light communica...
