OPTIMIZATION METHOD BASED ON FUSION OF VISIBLE LIGHT COMMUNICATION AND VISIBLE LIGHT POSITIONING

WIPO Patent Application WO/2023/039827

A1

Disclosed in the present invention is an optimization method based on fusion of visible light communication and visible light positioning. The method comprises: a terminal device decoding received modulation information of visible light communication, determining identifiers of visible light units, calculating the received optical power of a plurality of visible light units, and thereby determining position information by means of trilateration; the terminal device embedding the position information into a media access layer protocol, and sending same to a central controller; and by taking the optimization of the communication performance between the terminal device and the visible light units as a target, the central controller controlling and adjusting the radiation distribution of the related visible light units according to the received position information, and feeding back an adjustment result to the terminal device by means of the media access layer protocol. By means of the present invention, automatic adaptation to a change of the position of a user can be realized, thereby optimizing visible light communication and positioning.
