摘要随着电子技术和多媒体及网络技术的快速进展，视频监控系统正向嵌入式，数字化，网络化方向进展。嵌入式视频监控系统利用大规模集成电路和网络的科技成果。实现体积小，性能稳定，通讯便利的监控设备。本项目提出了在 ARM 微处理器平台上移植嵌入式 Linux 操作系统，并完成视频采集、压缩、控制等任务。系统硬件设备选择采纳实验室配备的 ARM9 微处理器 S3C2410 作为主处理器，利用 USB 接口的摄像头作为视频采集设备。为降低产品成本，在此基础上，借助Linux 下的开源软件，构建了整个嵌入式视频监控系统。关键词：视频监控 嵌入式系统 ARM9 Linux V4L 视频采集Abstract With the rapid development of the electronic technology, multimedia technology and network technology, video surveillance system is going to the embedded, digital, networked direction. Taking full advantage of LSI and networks of scientific and technological achievements, the embedded video surveillance system achieves delicate volume, stable performance, facilitates the communication of the surveillance equipment.The project is in arm microprocessor platform, and porting embedded linux system in it. It completes video capturing, compression, transmission and control tasks. The hard devices select the ARM9 (S3C2410) as the main processor in the system; and the USB camera as the device of video capture. In order to reduce the cost of the product, Based on the architecture and with the open source software in linux, the whole embedded video surveillance system is implemented.Keywords: Video Surveillance Embedded system ARM9 Linux video for linux 摘要..................................................................................................................................................11 绪论...............................................................................................................................................41.1 项目背景.......................................
