摘　　要：随着无人机技术的发展,无人机在各个领域得到了广泛的应用,其中无人机光伏巡检系统就是无人机的重要应用。视频图像数据传输功能是无人机光伏巡检系统的重要功能之一,设计了一套视频图像传输系统,主要包括视频图像采集、视频图像的编解码、基带信号处理和无线信道的收发。通过无人机上的摄像头进行视频图像的采集,视频编码芯片进行编码,利用基带信号处理技术将编码通过无线信道发送到地面接收端,在接收端利用解码芯片进行解码并显示视频图像。With the development of unmanned aerial vehicle(UAV) technology, UAVs have been widely used in various fields, of which drone photovoltaic inspection system is an important application of UAVs. The video image data transmission function is one of the important functions of UAV photovoltaic inspection system. A set of video image transmission system is designed, which mainly includes video image acquisition, video image encoding and decoding, baseband signal processing and wireless channel transceiver.The system collects video images through the airborne camera, encodes these images through the video encoding chip, uses baseband signal processing technology to send the encoded images to the ground receiving end via wireless channel for decoding and display by using decoding chip at the receiving end.
