摘要
详细介绍一种舰船灯光通信系统的总体组成结构、工作原理及系统接收端软件的设计。在灯光通信发送阶段,用户通过LED智能信号灯将信息进行编码后自动传输出去。在灯光通信接收阶段,高速摄像机进行人工瞄准目标信号灯,并实时采集图像,通过目标识别、图像分割处理和信息译码后,变成字符直接显示在屏幕。经白天相隔3nm处和夜晚相隔5nm处试验,系统工作稳定、安全可靠。
This paper describes the overall design of a ship light communication system principle and structure of the system, receiving terminal software. In the light of communication transmission stage, the user will encode information automatically transmitted by LED intelligent signal lamp. The receiving phase in light communication, high-speed camera for artificial target signal lamp, and real-time image acquisition, image segmentation, object recognition by processing and information decoding, a character directly displayed on the screen. By day and night at 3nm separated by 5nm test, the system is stable, safe and reliable.
