【摘要】 本文根据大楼电梯视频监控系统的要求,提出了一种基于嵌入式技术的网络视频监控系统实现方案。系统以嵌入式Linux和嵌入式微处理器S3C2410X为核心平台,通过嵌入式平台建立的基于TCP/IP协议的视频服务器,将USB摄像头采集来的图像数据压缩后,经过网络传输,完成对监控现场的网络视频监控任务。论文首先阐述了嵌入式网络视频监控系统的发展、现状以及整体构建,然后介绍了嵌入式Linux操作系统以及ARM处理器的发展情况,分析了主要外围电路的设计,以及如何在ARM硬件平台上进行嵌入式Linux内核的编译与移植,介绍了Bootloader的启动原理及运行过程,并对在Linux操作系统下的USB驱动程序的开发进行了研究。本文重点讨论了图像采集、编码和网络通信程序的设计原理与实现。最后进行了系统整体测试,并提出进一步开发设想。本文的研究结果具有较大的工程实际意义,对于基于IP技术的各种视频通信应用具有一定的参考价值。更多还原

【Abstract】 In this thesis, a resolution of network video surveillance system based on the embedded Linux and S3C2410X has been successfully developed, according to the requirements of building elevator video surveillance system. The system builds a video server based on TCP/IP protocol which can capture video signal from USB digital camera and transport the signal to client through Internet.Firstly the construction of embedded network video surveillance system is put forward and discussed. Secondly, some embedded operation systems and the situations of ARM processor are introduced,the design methods of main hardware circuits are analyzed,the theory of Bootloader is introduced, the driver of USB device is researched, and then the transplantation of embedded Linux on the ARM platform is accomplished. Further this thesis focused on discussing how to design image collecting, image coding, and network communication program. Finally, the system is tested and the plan of further development is proposed.Result of this research was provided with great signality of practical engineering and a valuable reference for application of video communicator base on IP technology.更多还原
