Abstract:In order to solve the problems of uneven light signal distribution and complicated calculations in the indoor visible light positioning，a visible light positioning algorithm was proposed based on the improved lamp source layout and particle swarms.By improving the layout of LED lights，the indoor light intensity distribution was more well-distributed，thereby reducing the influence of noise and making the received power of each indoor locations more balanced.An improved gravitational particle swarm algorithm was used for objective optimization.The simulation results showed that，in an indoor environment of 5 m×5 m×3 m，the maximum positioning error of the algorithm was 1.23 cm，and the average multipoint positioning error was 0.71 cm，which was better than TOA/RSS positioning method and fingerprint positioning method.
