Indoor VLC light Source Layout Design Method Based on Laser Scanning
In order to reasonably design the light source layout,a design method of indoor visible light communication(VLC)light source layout based on laser scanning is proposed.The indoor information(laser point cloud data)is acquired and processed by using laser scan-ning technology.According to the VLC signal transmission characteristics,the link model is constructed to obtain the impulse response functions of different links.Analyzing the illumination distribution by calculating the indoor illumination.The fitness function is con-structed,and the best scheme of indoor VLC light source layout design is obtained through iterative operation of particle swarm optimi-zation algorithm.The experimental data show that the ray tracing side view obtained by the proposed method has a large ray coverage,and the uniform illumination rate exceeds the minimum limit of 0.70lx,which confirms that the light source layout after the application of the proposed method is more reasonable.
