摘要
设计了一种基于V4L2的嵌入式视频监控系统,系统以S3C2440 a为硬件平台,以Linux操作系统为软件平台,选取Boa为嵌入式Web服务器。视频采集程序是针对V4L2设计的,V4L2是linux2.6内核所具有的视频设备驱动规范。采集到的视频信息可以利用TCP/IP协议传输,局域网内的用户使用浏览器,即可实时地获得视频图像,从而实现实时视频监控。实验结果表明系统性能稳定、实时性好,具有广泛的应用价值。
An embedded video surveillance system based on V4L2（video for linux two） is designed, which uses S3C2440a as hardware platform, linux system as software platform and Boa as embedded Web server. The software of video capture is designed based on V4L2, which is the API（Application Programming Interface） of video capture device driver. Video data can be translated by TCP/IP protocol. Remote real - time monitoring video can be displayed by browser to users. The experimental result shows that the system has high practical value, and this system can be widely used in many occasions.
