基于FPGA的实时图像采集与Sobel边缘检测

摘要

运用现场可编程门阵列(FPGA)的流水线和并行技术,构建灵活高速的可编程图像采集与预处理系统.利用基于QuartusⅡ提供的参数可设置宏功能模块,实现了Sobel边缘检测算法,并实时显示边缘检测后的图像,获得了很好的边缘检测效果,缩短了开发周期.%A high-speed flexible programmable image acquisifion and preprocessing system is constructed by the line and parallel technology of field programmable gale array (FPGA). A new design method of Sobel edge detection algorithm based on the Quartus Ⅱ provided parameterizable megafunctions is introduced, and accomplishes real-time display of the image edge detection. The new design method shortens the developing cycle and obtains commendable effect of edge detection.
