摘　　要：针对传统的PCI图像采集卡的弊端,利用Altera公司的DE2开发平台,设计了基于现场可编程门阵列(FPGA)的图像采集与VGA显示系统。该系统以嵌入了NiosⅡ软核的可编程逻辑芯片FPGA作为控制器,以图像传感器、数字存储器、视频D/A转换器、VGA显示接口等作为FPGA外设,利用可编程片上系统(SOPC)技术实现对FPGA及其外设的编程与控制,最终实现对实时图像的采集、处理与显示。设计结果表明,利用SOPC技术实现的电子系统具有设计方法灵活高效、可移植性强、易于实现高速数据采集、通用性好等优势。Concerning the drawbacks of traditional PCI frame grabber,using Altera＇s DE2 development platform,image acquisition and VGA display system of programmable logic chip based on Field-Programmable Gate Array（FPGA） were designed.This system used the programmable logic chip FPGA which was in-built into soft-core NiosⅡ as the controller.The FPGA has image sensor,digital memory,video D/A converter and VGA display interface as its accessories.System used System On a Programmable Chip（SOPC） technology to obtain control and coding over FPGA and its accessories and eventually to acquire,process and display the real-time images.The design results prove that,the electronic system based on SOPC technique is flexible and efficient in terms of designing,ported strong,easy to achieve high-speed data acquisition,and it has high compatibility.
