本文提出了一种基于小型彩色LED和智能手机的视距LED-摄像机通信系统。我们设计了一个廉价的原型，作为物联网近距离通信框架的概念证明。我们评估了系统的性能、可靠性和环境对LED到相机通信的影响，强调了每秒几千比特的吞吐量是可以达到的。最后，针对系统中遇到的具体问题，设计了一种实时、高效的LED检测和图像处理算法。
In this paper, we propose a line of sight LED-to-camera communication system based on a small color LED and a smartphone. We design a cheap prototype as proof of concept of a near communication framework for the Internet of Things. We evaluate the system performance, its reliability and the environment influence on the LED-to-camera communication, highlighting that a throughput of a few kilobits per second is reachable. Finally, we design a real time, efficient LED detection and image processing algorithm to leverage the specific issues encountered in the system.
