摘　　要：为提高可见光通信(VLC)的传输效果,设计了一种数字图像传输装置。该装置通过单片机控制OV2640数字摄像头实现数字图像的实时获取和压缩,利用串口将压缩的图像数据流加载到装置发射模块,接收模块对光信号进行接收还原,并将数据传输至上位机完成图像的解码与显示,传输图像画质清晰、失真度低。分析并测算了装置的信道增益、总失真度及传输距离,测试结果表明装置综合传输性能良好,满足设计要求。In order to improve the transmission effect of visible light communication, a digital image transmis- sion device is designed. The device achieves real-time acquisition and compression of digital images by controlling the OV2640 digital camera. The compressed image data stream is loaded into the transmitter module through the serial port. The receiver module receives and restores the optical signal, and transmits the data to the host computer to decode and display the image, The quality of the image transmitted is clear and the distortion is low. The channel gain, total distortion and transmission distance of the device are analyzed and measured. The test results show that the device has good transmission performance and can meet the requirements.
