【摘要】 目前，视频监测系统在各个领域得到了广泛应用，主要用于安全防范、信息获取等方面。网络技术、视频处理技术和嵌入式技术的迅速发展，极大地推动了视频监测技术的发展进程，促使视频监测技术向数字化、网络化以及智能化的方向发展。本文在分析了视频监测技术发展的基础上提出了以嵌入式ARM开发板和USB接口摄像头为主体，以Web访问为交互方式的一套嵌入式视频监测系统的解决方案。该方案采用Philips公司的32位高性能ARM7芯片作为微处理器，以μClinux为嵌入式操作系统，通过摄像头采集图像并利用JPEG格式来实现图片压缩解码；在系统前端运行嵌入式Web服务器，基于TCP／IP协议通过网络传输图像信息；用户可以在远端通过浏览器访问，以网页内嵌Java Applet的直观形式实现对远程信息的监测。该系统开发成本低、性能高并且使用方便。本文从系统的总体规划、模块划分，到软硬件各模块的设计，再到各模块的具体实现都进行了较为详细的描述。并重点阐述了系统主要软件模块的开发实现过程，并给出了代码实现。在文章最后，指出了在本系统存在的一些问题，并对下一步的工作提出了展望。更多还原

【Abstract】 In recent years, video surveillance system has been used extensively in every field, which mainly used for security system, information acquisition and so on. Rapid development of technology in the video, network and embedded system is a great promotion for the improvement process of video surveillance technology, and the developmental trend of video surveillance towards to digital, networking, and intelligence.Based on the analyses of the current development of video surveillance, the paper bring forward a solution which is made up of embedded ARM MCU and webcam with USB interface, and we can visit and control the system through Web browser. This scheme adopts 32bit high-performance ARM7 of Philips as microprocessor, adoptsμClinux as operating system, adopts webcam to gather video data and use JPEG protocol to realize the compression of the video picture. The server of the system runs an embedded web server which transmit video information through the network, users can make use of Web Page which contain Java Applet to realize remote surveillance. The system has low cost, high capacity and efficiency and is easy to use.In this paper, we detailed introduce the solution from its collectivity design, division of modules of software and hardware, to the design and coding of software modules. And then, we especially expatiate development process of main software modules, and provide codes. At the end of the paper, we point out some problems existing in this system and put forward the suggestion on the next work.更多还原
