摘要
视频监控系统已经逐步渗透到了社会生活中的各个领域。随着视频压缩技术、数据传输等相关技术的不断发展,传统的视频监控方式很难满足用户的需要。文中介绍了一种基于S3C2440嵌入式平台的视频监控系统,并通过局域网传输使得网内的计算机可以实时地获得视频图像,从而可以达到远程监控的目的。鉴于Linux内核的开源及其稳定性,采用其作为操作系统,从而使整个系统具有较好的实时性和稳定性。从系统整体出发简要地阐述了系统的功能原理、部分硬件模块的设计方案,描述了嵌入式系统开发的流程、嵌入式系统开发环境的搭建步骤并介绍了Linux操作系统下基于视频采集编程接口Video4Linux的视频采集流程。
The video surveillance system has permeated into various fields in our life step by step.Along with the continuous development of many techniques such as the video compression technique,the data transmission technique,and so on,many traditional methods of video surveilance can hardly satisfy our requirement.Introduce a method of the video surveillance system based on S3C2440,and any computers which are under the same network can capture the real-time video image through the LAN,by this means,a method of remote monitor can be achieved.In view of the feature of open source and the stability of the Linux core,this program adopt the Linux OS to make the whole system attain a higher feature of real-time and stability.Take the video surveillance system as a whole and present the principle of the system,the design program of parts of hardware module,describe the flow of the embedded system development,the step of the establishment of the development environment and the flow of video capturing based on the programming interface-Video4Linux-in the Linux operation system.
