Abstract
A positioning method based on a visible light source, a mobile terminal, and a controller. 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, 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. Hence the method reduces the complexity of a positioning process.
