基于SOPC的实时图像处理系统设计

摘要

Based on SOPC （system on programmable chip）, the hardware and software designs of the image processing system are introduced. The controller IP cores of the CMOS image sensor and VGA display are designed to acquire and display the images respectively. The algorithm of the image edge detection based on the Sobel arithmetic operators is used by the Nios Ⅱ soft core. Using this system a good real-time performance can be obtained, and the software and hardware designs of image processing system are greatly simplified.%介绍了基于可编程片上系统（system on programmable chip，SOPC）技术的图像处理系统的软硬件设计，创建了CMOS图像传感器控制器IP核和VGA显示控制器IP核，实现了图像的采集和显示，并由NiosⅡ软核实现了基于Sobel算子的图像边缘检测算法。采用此系统不仅可以获得良好的实时性，还能大大简化图像处理系统的软硬件设计。
