摘　　要：传统的二值化图像处理需要将采集的图像先保存到电脑上,再用matlab进行二值化处理。图像处理起来比较麻烦,也不能对图像进行实时显示和保存。本文主要阐述了一种集成的解决方案,对于图像的二值化处理直接在FPGA上实现,无需电脑软件的二次处理。本系统主要由FPGA、SDRAM、CMOS图像传感器、USB组成。经过硬件系统处理之后,可以得到二值化之后的实时图像,上位机可以实时显示和保存二值化图像,简化了用电脑采集处理的过程,对图像采集处理系统集成化有一定的促进作用。Traditional binarization image processing requires that the collected images be saved on the computer,and then binarization processing is carried out with MATLAB.Image processing is more troublesome,and the image can not be displayed and saved in real time.This paper mainly describes an integrated solution,for the image binary processing directly on FPGA,without the secondary processing of computer software.The system is mainly composed of FPGA,SDRAM,CMOS image sensor and USB.After processing by hardware system,real-time image after binarization can be obtained,and the upper computer can display and save the binarization image in real time,simplifying the process of computer acquisition and processing,and promoting the integration of image acquisition and processing system.
