Abstract

The invention discloses an indoor positioning method, device and system based on visible light and a light source. The indoor positioning method based on the visible light comprises the steps that the light source is shot, and images which correspond to the visible light and are emitted from the light source are obtained, wherein the visible light is modulated and contains the identity information of the light source; light and dark strips in the images are obtained, wherein the light and dark strips in the images correspond to the identity information of the light source; the light and dark strips are identified to obtain the identity information of the light source; the position corresponding to the identify information of the light source in a map is sought, and the current position is obtained. According to the indoor positioning method, device and system based on the visible light and the light source, the problem that indoor positioning precision is low in the prior art is solved, and the effect of improving the positioning accuracy is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an indoor positioning method, device, system and light source based on visible light. Background technique [0002] With the development of science and technology, indoor positioning and navigation has been put on the agenda, and more and more people pay attention to it and apply it in daily life. The Global Positioning System (GPS) is currently the most widely used positioning technology, but , because the signal is affected by the building, the positioning signal using GPS is very weak when it reaches the ground, the positioning accuracy is low, and the requirements for indoor positioning cannot be realized, and the cost of the locator terminal using GPS is very high. [0003] Aiming at the problem of low indoor positioning accuracy in the prior art, no effective solution has been proposed yet. Contents of the invention [0004] The main purpose of the present invention is...
