无人机地面站图像压缩传输系统设计与应用

Design & Application of Video Image Encode and Transmission System for UAV GCS

针对无人机地面指挥控制系统要实现互连、互通、互操作的网络化要求,设计了视频信号实时网络传输和显示系统。系统由基于DSP的服务器端和通用客户端播放器组成,服务器端通过设置并行任务完成视频信号的实时采集、编码和发送,客户端完成视频信号的实时接收、解码和播放,从而使系统实现了图像信息在地面站所有显示终端上的实时显示。实验结果表明,系统完全满足无人机地面站系统功能及指标要求,并且通过网络化技术节省了地面站宝贵空间资源,系统设计方法对同类型系统具有一定借鉴意义。

In order to fulfill the networking requirement of UAV Ground Control Station（GCS） video image signal is sent through network and displayed in real time.The system consists of server based on DSP and general software client.The server digitizes,encodes and sends the video signal in real time by setting three parallel software tasks,the client receives,decodes and displays the video image in real time.Thus the system realizes the function of displaying video image on all the monitor terminals in the GCS.Real flight tests show that the system meets all the feature and function requirements of GCS.Meanwhile it saves precious space in GCS through digital networking design.The design concept of this system can be used for reference for similar system design.
