【摘要】 针对现有舰船灯光通信系统通信速率低、自动化程度低等缺点,设计了一种应用于移动目标的灯光通信系统。该系统的发射端通过控制探照灯发送莫尔斯码信号,接收端则用帧频为100帧/秒的CMOS相机对莫尔斯码信号进行接收,数据经图像处理后解码显示在计算机屏幕上。系统具有自动跟踪控制功能,可对信号光进行实时跟踪。更多还原

【Abstract】 Considering the shortcomings of the existing shipboard low communication rate of light communication system and low degree of automation,a moving target of light communication system is designed. The transmitter modulates the Morse code signals on the searchlight which is received by the CMOS camera with a frame of 100 frames per second. The received signals are decoded and displayed on the computer screen by image processing. Automatic tracking function is added into the system and can timely track the signal light. Besides we have carried out the outdoor communication experiment to verify the system.更多还原
