Abstract

Visible Light Communication using modulated LED lighting infrastructure as transmitters and optical cameras as receivers has a lot of new and useful applications as an alternative way of transmitting data for road traffic signaling, navigation inside large buildings, etc. This paper provides extensive and exhaustive simulations to test the functionality and performances of an indoor navigation system based on Optical Camera Communication developed by the authors, by considering the avoidance of light flickering at the emitter and the real-world capture conditions of smartphone cameras used as receivers. The experimental results show that the proposed system can achieve good decoding results in real-word scenarios, even in the presence of camera frame rate errors and independent on the moment the capturing device starts the decoding process.
一种用于室内导航的可见光通信系统的性能评估
可见光通信以调制LED照明基础设施作为发射器,光学摄像机作为接收器,作为道路交通信号、大型建筑物内导航等数据传输的替代方式,具有许多新的和有用的应用。本文提供了广泛而详尽的模拟,以测试基于作者开发的基于光学相机通信的室内导航系统的功能和性能,考虑避免发射器处的光闪烁和用作接收器的智能手机相机的真实捕获条件。实验结果表明,该系统在真实场景下,即使存在摄像机帧率误差,且与捕获设备开始解码过程的时刻无关,也能取得良好的解码效果。
