【摘要】 本文分析了国内外视频监控系统的发展现状，针对当前省广播监测中心具体要求和工程实际情况，介绍了一种基于ARM的嵌入式视频监控系统。该方案相比于传统的多媒体监控系统具有体积小、成本低、稳定性高、实时性好等优点，具有很强的实用性价值。论文完成了基本的硬件系统设计和软件开发。硬件方面采用USB摄像头与S3C2410处理器组成嵌入式视频采集装置，并通过以太网连接宿主机从而组成视频监控系统。软件方面分为系统软件的移植和应用软件开发两方面。系统软件方面包含ARM平台的BootLoader和嵌入式Linux的移植；应用软件方面包含前端ARM平台嵌入式视频采集软件设计，前端TCP视频服务器程序设计，宿主机TCP客户端程序设计和宿主机视频解压显示程序设计四个部分。论文的最后对系统设计所完成的内容进行了总结，并提出了改进方法。更多还原

【Abstract】 By analyzing the situations of the video inspecting system home and abroad, aimingat the demand of the broadcast center and the practical applications, this thesis talks abouthow we designed a system of video inspecting based on ARM. Comparing to traditionalmultimedia surveillance system, this scheme has the characteristics of small volume, lowcost, high stability and etc, therefore, it has good applied and development outlook. Thedesign of hardware system and the development of software system are mainly discussedin this thesis.With regards to the hardware design, the embedded video capture system is consist ofUSB camera and S3C2410 as its CPU, and as it connects to PC through Ethemet, thesystem of video inspecting can work well.As far as the software design, the system software and the internet applications mustbe designed. First we must port the BootLoader and embedded Linux kemel to the targetof ARM platform. Then, a system of video capturing and a video server based on TCPneed to be designed to run on the platform of ARM. In the end, we should design a TCPclient to get the compressed video data from the target of ARM platform, and then we candesign a program to decode the compressed video data and display on the screen to satisfythe needs of video inspecting.Finally, this thesis summarized the completed works, and the method of futureimproves has been given too.更多还原
