摘　　要：传统图像采集系统具有复杂、体积大、不便携带等缺点,而嵌入式图像采集系统集图像采集、显示、处理于一体,具有体积小、功耗低的优点。针对安防监控系统的需要,设计出一种基于ARM的图像采集系统。该系统以S3C2410(ARM9)为核心,利用USB摄像头、显示屏和存储器来构建图像采集和处理系统,并搭建必要的外围电路和通信接口,完成了硬件平台的设计。然后移植嵌入式操作系统和驱动程序,最终实现了图像数据的采集、显示和存储等功能,采集图像清晰,符合系统要求。Traditional image acquisition system has the disadvantages of complex,bulky,inconvenient to carry.The embedded image processing system integrates all the functions of image capturing,displaying and processing as well as takes the advantages of small size and low power consumption.According to the need of security monitoring system,a kind of image acquisition system based on ARM was designed.The systerm takes S3C2410（ARM9） as the core to construct the image acquisition and processing system with USB camera,monitor and memory,and builds the necessary peripherals and communication interfaces to complete the design of the hardware platform.After that,embedded operating system and drivers were transplanted,eventually the functions of image data collection,display and storage were realized,images acquisition were clear and the systerm turns out to meet the requirement.
