针对目前对视频监控系统的需求，本文通过对目前主流视频监控系统方案的研究，提出了基于WEB架构的嵌入式Linux视频监控系统。该系统通过基于V4L编程的视频采集方式，借助嵌入式Linux的网络功能，以WEB服务器的形式将视频图像信息传输出去。该系统以UP-TECHPXA270-S教学科研平台作为硬件开发平台，以USB WebCam摄像头作为视频获取工具，选择嵌入式Linux操作系统为软件开发平台，通过开源软件库libjpeg对视频图像进行软件压缩，在客户端可跨平台以浏览器的方式访问嵌入式视频传输服务器。系统测试结果表明，本文提出的系统切实有效。

According to the need of video monitoring system at present, through the research of the current video monitoring system plan, the paper proposed the embedded Linux video monitoring system based on the WEB structure. The system transfers the video information out through V4L programming based video acquisition methods, with tha aid of embedded Linux network function, and in the form of WEB server. This system takes UP- TECHPXA270- S teaching and scientific research platform as a hardware development platform, with USB Webcam camera as a video acquisition tool, selects the embedded Linux operation system as software development platform, carries out the software compression of video image through the KaiYuan software library--Libjpeg, in the client-side, we can cross the platform to visit embedded video transmission server in the way of browser. System testing results show that the proposed system is practical and effective.
