冷轧带钢表面缺陷视觉检测系统
Cold Rolling Strip Surface Defect Vision Detection System
摘要
Abstract
The cold rolling strip surface defect detection system based on machine vision was designed with multi-classification and modularization idea. For realizing real-time characteristics of system, high-speed linear CCD camera and relational high-speed fiber image collection card, high-speed FPGA image processing card designed by ourselves were adopted in hardware; RTAI-Linux operation system and parallel processing method were adopted in software. Image segmentation parallelization experiment result indicates that the processing speed of quad-core processor is 3. 2 times faster than that of single core; and the system' s performance is improved effectively.关键词
