Beschreibung
Zusammenfassung:	The invention relates to a three dimensions indoor positioning method based on visible light signal intensity, belonging to the visible light communication technical field. The method comprises: first, according to frame header intensity information, utilizing the frame header intensities of LED signals received by a receiver to determine the height information Z of a light detector by establishing a fingerprint database; and second, utilizing the RSS measurement method to determine horizontal information X and Y. The method has a simple structure, is easy to operate and realize, does not need additional sensors, realizes height coordinate positioning under the condition of maintaining the hardware of an original two dimensional visible light positioning system, and thereby realizes indoor space positioning. Compared with a pure fingerprint database indoor space positioning method, the method substantially reduces the calculated amount in a whole process, and increases a positioning speed.
