中文摘要：

基于ARM体积小、低功耗、低成本、高性能的特点,设计了一种图像处理并带有报警功能的系统。该系统以Tiny6410核心板——一款以ARM11芯片（三星S3C6410）作为主处理器、CPU基于ARM1176JZF-S核设计的嵌入式核心板——为主控板,加上外围设备以及USB摄像头,实现了图像的采集与处理。在此基础上加入了蜂鸣器和LED灯,在出现异常情况时,实现报警功能。该系统采用Linux嵌入式操作系统,并设计了软件流程。实验结果表明：该系统能够很好的解决图像采集的实时问题及准确性,由于加入的报警系统,更是提高了系统的可靠性,能够及时发现问题。系统易于实现,成本比较低,功耗低,具有高的使用性。

英文摘要：

Based on ARM＇s characteristics of small volume, low power consumption, low cost and high performance, the paper designs an image processing system with alarm function. The system is based on Tiny6410 core plate-an embedded core board with ARM11 chip （S3C6410） as the main processor and CPU based on ARA41176JZF-S kernel-as main board, and adds peripheral equipment and USB cam- era, realizing image data acquisition and processing. On the basis of above, joining the buzzer and the LED lamp, it realizes alarm function when the abnormal situation occurs. The system uses Linux embedded operating system, and designs software process. The experimental re- sults show that： the system can solve the problem of real-time and good accuracy in image acquisition. Because of joining the alarm system, it improves the reliability of the system and discovers problems in time. The system is easy to implement, low cost, low power consumption, with the use of high.
