基于FPGA/SOPC架构的面阵CCD图像采集系统的设计
Design of Image Acquisition System Based on Array CCD with FPGA/SOPC Architecture
摘要
针对交通和监控等行业对面阵CCD图像采集系统小型化与低功耗的需求,设计了一种基于FPGA架构的面阵CCD图像采集系统。系统利用FPGA作为视频信号采集控制模块、利用FPGA内建NiosⅡ软核微控制器作为图像处理单元,并利用μC/OS-Ⅱ实时操作系统对多个任务进行管理。该系统扩展灵活,可以满足小型化与低功耗的要求。
Abstract
In order to satisfy the requirement of miniature and low-power dissipation for the array CCD in the applications of traffic and surveillance, an image acquisition system based on array CCD with FPGA/SOPC architecture is designed. This system includes FPGA as the controlling module to collect the Video signal, build-in NiosⅡ microcomputer control unit (MCU) as the image processing unit, and μC/OS-Ⅱ operating system as the manager of multiple tasks. This system extends universally and satisfies the requirement of miniature and low-power dissipation.
