无人机网络视频系统是无人机重要组成部分,文章设计了一套嵌入式视频采集传输系统；该系统以Intel PXA270为硬件核心平台;采用Linux操作系统,重新编译配置内核,以驱动USB网络摄像头；对USB网络摄像头采集到的图像数据进行H264压缩,然后通过CDMA网络把高清视频信号无线传输到地面接收站的vlc播放器解码显示,实时性很好,图像质量清晰；可以完成小型无人机侦察勘探、自主导航的功能.具有广泛的应用前景.%Network video system is an important part of UAV, this paper design an embedded video transmission system. The system makes use of Intel PXA270 embedded microprocessor as its hardware core. The operating system is Linux system. In order to dirver USB network webcam, we have to re-compile and re-configure the Linux kernel. The USB network webcam is used to capturing video image, then use CDMA wirele network transfer the High-definition video signals to ground station to display. This can achieve the UAV capabilities for exploration and reconnaissance , Autonomous navigation. Has broad application prospects.
