摘　　要：为了合理设计光源布局,提出基于激光扫描的室内可见光通信(Visible Light Communication,VLC)光源布局设计方法。应用激光扫描技术获取并处理室内信息(激光点云数据)。根据VLC信号传输特征构建链路模型,获取不同链路的脉冲响应函数。计算室内光照度,并分析光照度分布情况。构建适应度函数,通过粒子群算法循环迭代运算,获得室内VLC光源布局设计的最佳方案。实验数据显示:应用提出方法获得的光线追迹侧视图光线覆盖范围较大,均匀照明率数值超过了最小限值0.70lx,证实了提出方法应用后的光源布局更加合理。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 scanning 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 constructed,and the best scheme of indoor VLC light source layout design is obtained through iterative operation of particle swarm optimization 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.
