一种用SAR进行织物疵点检测的方法

摘要

目前的疵点检测方法一般基于织物的可见光图像,对色彩或灰度的依赖过大,以致影响到后续的图像处理算法的分类效果,是当前检测算法所面临的严重问题.为解决当前织物疵点检测系统中存在的问题,提出了一种新的利用合成孔径雷达技术进行疵点检测方法.该算法由于与传统的可见光成像机制不同,利用合成孔径雷达技术,避免了对可见光成像依赖性,用sAR的理论和算法解决了一些成像及识别关键问题,理论分析和实测数据的处理结果验证了该方法的有效性.%The existing fabric defection method mainly depend on the brightness of visual light or gray intensity of image, therefore, the effect of classification and identifition is deteriorated when the high quality fabric image unable to obtained. Aim at solving difficulties or fatal disadvantage in existing fabric defects detection system, a novel system of fabric defects detection system by using the synthetic Aperture radar (SAR) is presented. Different from the mechanism used in imaging approach, some vital disadvantage can be avoided in SAR fabric defect detection system. Theory of SAR method is introduced, key problem in SAR technique is brought forward and solved, the numerical example study and analysis and the result of real data processing verified the effectiveness of proposed method.
