Supermarket Commodity Guide System Based on Indoor Visible Light Positioning

Aiming at the problem that there are many commodities in large supermarkets and it is inconvenient to find them, this paper applies the visible light positioning technology to the supermarket, makes full use of the supermarket LED lighting and uses the optical communication technology to transmit the commodity information. The system uses the centroid positioning algorithm as the cargo positioning method. The design first completes the transmission of commodity position information through the optical signal, and then calculates the cargo position coordinates through the centroid positioning algorithm. Through the analysis of simulation results, in the free space environment, glare can achieve more accurate positioning and have less positioning node error.
