摘要
针对传统的视频监控系统稳定性低,成本较高,图片压缩率低,网络传输时延高等问题,提出一种基于嵌入式Linux的视频图像处理以及网络传输监控系统。该系统以海思HI3518E为硬件平台,以Linux 3.4.35为软件平台,采用AR0130摄像头采集图像数据,使用H.264软件编码技术对图像进行压缩,通过TCP/UDP协议对控制流和视频流进行打包发送,PC端通过VLC media player解码播放。实验结果表明,该系统稳定性高,体积小,成本较低,采用软件压缩方式使得视频图像传输更高效,视频能在客户端清晰、流畅地显示,满足监控需求。
Aiming at the problems of low stability,high cost,low picture compression rate and high network transmission delay,this paper proposes a video image processing and network transmission monitoring system based on embedded Linux.The system uses HiSilicon HI3518E as the hardware platform and Linux 3.4.35 as the software platform.It uses AR0130 camera to collect image data,uses H.264 software encoding technology to compress images,and packs control flow and video stream through TCP/UDP protocol.Send,the PC side is decoded and played by VLC media player.The experimental results show that the system has high stability,small size and low cost.The software compression method makes the video image transmission more efficient,and the video can be clearly and smoothly displayed on the client to meet the monitoring requirements.
