Abstract

This paper designs and realizes an indoor visible light localization system based on identification method.The system first loads the current position information to the LED light sources.Then the information will be transmitted to the mobile terminal through the wireless optical link

which calculate their relative positions in the environment according to the received information from the mobile terminal

and mapped to the map.Therefore

the system can achieve visible light positioning function

which meets the basic requirements of the lighting at the same time.We use the Stm32 processor as the main controller of the system

and design a kind of coding protocol

which can be used to transmit the position information in the visible light communication process.The characteristics and driving circuits of LED light sources are tested at the transmitter

which can guarantee the basic lighting and communication.The receiver uses C#language to compile the software of the host computer in order to realize the function of mapping and real-time updating of the mobile terminal’s position.The results show that the system can achieve ideal positioning performance.
