一种基于FPGA的高速图像采集及显示电路设计

为了实现高速图像采集和显示,采用CamLink接口和DVI接口来完成视频采集和显示。详细介绍了基于FPGA采集和显示的系统组成,给出了CamLink接口采样模块和DVI显示模块的工作流程及硬件电路实现方式。该硬件电路基于CPCI总线设计,实现了计算机与图像电路之间的高速数据交换。设计中使用的FPGA是Altera公司的EP2S30F672I4,用该FPGA进行配置和验证,测试表明该设计不仅实现了图像高速采集和显示,且使图像清晰、系统稳定可靠。

Design of High-speed Video Acquisition And Display Circuit Based on FPGA

The design used CamLink interface and DVI to realize high-speed video acquisition and display.This paper introduces the system of video acquisition and display based on FPGA,shows how the sample module based on CamLink interface and DVI display module worded.And based on CPCI bus,high-speed image data exchange between computer and image circuit was realized.EP2S30F672I4 FPGA of Alter Company is used to config and verify the design.The test manifestes the design not only realized high-speed video acquisition and display,but also made video clear,system reliable.
