基于嵌入式Linux的图像监控系统
摘要
图像监控系统是一门集计算机技术、通信技术和多媒体技术于一体的综合系统。它以直观、方便、信息内容丰富等特性被广泛地应用于各个方面。随着嵌入式技术和图像处理技术的发展,使得监控图像和视频的网络实时传输和控制成为现实。
本系统是基于嵌入式Linux的图像监控系统。本系统采用Linux系统作为服务器端平台,以ARM9内核的S3C2440作为服务器平台处理器,以USB摄像头作为图像采集设备,用开源软件mjpg-streamer对图像视屏数据流进行MJPG压缩处理,并且通过以太网传输。着重于实现一个易搭建,易配置,通用性好,能用于临时性监控的网络图像视频监控服务器,可让客户机通过浏览器实时监控远程目标摄像头,并实现远程共享摄像头的图像监控系统。
论文首先简要介绍了图像监控系统的国内外现状和本系统的课题背景和意义所在,分析了以s3c2440微处理器为核心的图像监控系统的硬件方案的设计,然后详细描述基于linux系统平台的构建,再者重点分析应用软件的程序和设计流程,并深入分析图像采集过程和网络传输图片视频的技术以及算法,以求达到处理监控图像视屏的作用。

ABSTRACT
Image monitoring system is an integrated bined puter technology, communtication technology and multimedia technology. It takes intuitive, easy and abundant information and other features to be widely used in various aspects. With the development of embedded technology and image processing technology ,work monitoring real-time image and video transmission and control e a reality.
The system is based on embedded Linux image monitoring system. The system uses the Linux system as a server-side platform, and S3C2440 ARM9 core processor as a server platform , using USB camera as image acquisition devices, using open source software Mjpg-streamer, to deal with the image screen pressed data stream ,and transmitted via .Focused on delivering an easy to build, easy configuration, common good, can be used for temporary work image video surveillance server,Allowing clients real-time monitor by a browser remote target camera, and share remote video surveillance camera system.
The paper introduct briefly Firstly and Image Monitoring System Current Status and the system background and significance of the subject, analyzed to s3c2440 microprocessor core image monitoring system hardware in the detailed description of the construction based on linux platform, also analysis application software key procedur
