基于可见光通信技术(VLC)光定位对照度变化的需求，建立了以发光二极管(LED)为光源的实验平台，并借助矩阵实验室(Matlab) GUI设计了一款可为室内光定位提供照度分布的软件。该软件模拟获得了室内照度强弱的变化分布图，与理论仿真结果吻合，证明了该软件的有效性。

Based on the requirements for the optical localization of the visible light communication (VLC) technology, an experimental platform with LED sources was established, and a software that could provide illumination distribution for indoor optical localization with Matlab GUI was designed. The simulation results show that the varied distribution of the indoor illumination intensity could be obtained, which is consistent with the theoretical results, thus proving the validity of the software.
