Internet网络视频监控在嵌入式系统下的设计与实现

具有图像采集、传输和处理等功能的嵌入式视频监控设备可以在Internet上传输图像数据，基本上不受距离限制，需重新布线；性能更稳定，且便于安装、维护。文中讨论了以CMOS图像采集芯片，ARM微处理器和嵌入式操作系统为核心的监控设备的软硬件设计。重点介绍了ARM单片机子系统、图像采集模块、图像存储控制模块等硬件部分的设计原理与实现。介绍了在uClinux下驱动程序、图像采集、图像压缩算法、网络通讯程序的实现原理与过程，以及图像合成、处理的方法。

TheDesign and Realization of Internet Web Video Monitoring in Embedded System

A kind of Remote Video Monitoring Device Based on Embedded system can transmit the picture data on the internet, being free from the distance restrict, needless repeated wiring and not easily be interfered by other parts of the computer system. Therefore it is more stable and easy to fixing, maintain. The software and hardware design of the monitoring system on the basis of CMOS image sensors. ARM microprocessor and embedded OS are introduced in this thesis. Further, this paper focused on discussing how to design the hardware part including ARM singlechip sub- system, image gathering module and image buffering control module. Driver of uClinux, image Collecting, image coding, network communication program are analyzed and realized also. In the final, the author discussed the methods of image synthesising and processing.
