摘　　要：介绍一种基于FPGA和CIS(接触是图像传感器)全新的高速高精度图像采集系统。系统由1200dpi的CIS作为图像传感器,处理来自36个通道的模拟并行数据的12个高速AD,一片作为主处理器对图像数据做拼接和处理的FPGA芯片,和以LVDS方式将图像数据传至PC做进一步处理的Camera-link接口组成。实验结果表明采集的速度可高达12m/min,检测最小孔径为30μm,检孔误差小于0.5%。本图像采集系统已成功应用到自动光学检测设备上。A new kind of high-speed and high-precision image acquisition system based on FPGA and CIS is proposed.It is composed of a high-speed and high-precision CIS with 1200dpi as image sensor,12 AD processing high-speed simulation data from 36-channel,One FPGA chip as the host processor splicing and processing image data,and the Camer-link interface which transmittes image data in the form of LVDS to PC to do further processing.The result of experiments show that the speed comes quickly up to 12m/s,the minimum aperture-diameter up to 30 μm,hole-checking error below 0.5%.
