摘要 针对用于铁路、公路等行业移动检测的面阵CCD图像采集系统对于小型化与低功耗的需求,设计了一种基于ARM7与FPGA架构的面阵CCD图像采集系统。本文介绍了系统设计的基本原理,并着重阐述了图像A/D转换单元、图像缓冲单元、图像处理单元等系统主要组成部分的软、硬件设计。本系统利用FPGA控制视频信号的采集、ARM7微控制器作为图像处理单元,并利用μC/OS-II实时操作系统对多任务进行管理,系统扩展灵活,满足小型化与低功耗的要求。 This paper design a area-array CCD image acquisition system based on ARM7 and FPGA architecture, which is targeted for the area-array CCD image acquisition system's requirements of miniaturization and low power used in the railway,highway and other industries moving detection. This article describes the basic principle of system design, and focuses on the the system software and hardware design such as the image A/D conversion unit, image buffer unit and the image processing unit and other major components. This system uses FPGA to control the video signal acquisition, takes the APM7 as an image processing unit, and uses μC / OS-Ⅱ real time operating system for multi-task management. This system expands flexibly and can meet the miniaturization and low power consumption requirements.
