我们提出了一个可见光通信系统，使用商业相机，同时实现通信和定位，这是必不可少的智能交通系统（ITS）。发射器（Tx）将数据作为LED的快速闪烁光发射。接收器（Rx）使用带跨屏滤波器的卷帘快门传感器捕获信号。与以往没有跨屏滤波器的系统只能实现短距离和单用户通信不同，所提出的系统可以通过使用跨屏滤波器在特定方向上漫射入射光来实现远距离通信。此外，所提出的系统有可能实现多用户通信和定位，这需要一个高速相机，使用商业相机。我们在室内实验中评估了该系统的性能。实验结果表明，该系统可以提高通信范围相比，以前的系统。
We propose a visible light communication system using a commercial camera that achieves communication and positioning simultaneously, which is essential for intelligent transport systems (ITS). The transmitter (Tx) emits the data as fast-blinking light of the LED. The receiver (Rx) captures the signal using a rolling-shutter sensor with a cross-screen filter. Different from the previous system without a cross-screen filter, which can only achieve short-range and single-user communication, the proposed system can achieve long-range communication by diffusing the incoming light in a specific direction using a cross-screen filter. Furthermore, the proposed system has the potential to achieve multi-user communication and positioning, which used to require a high-speed camera, using a commercial camera. We evaluated the performance of the proposed system in indoor experiments. The experimental results suggest that the proposed system can improve communication range compared to the previous system.
