摘　　要：针对织物常见的破洞、断经和缺纬3类疵点,提出了一种基于数学形态学的疵点检测方法.利用自相关函数和FFT找出织物经纬结构的重复单元,以其为依据,用形态学中腐蚀背景和膨胀目标的方法检测图像中的疵点信息,在传统的形态学处理法之后,采用开运算进一步地消除噪声,突出疵点,在此基础上,利用MATLAB语言开发了系统原型,通过实验验证了形态学检测疵点的可行性.In this paper,a method based on mathematical morphology is presented to detect fabric defects including hole,warp-lacking and weft-lacking.First repeat units are identified through autocorrelation function and FFT.Second,mathematical morphological erosion and dilation methods are used to detect the defects information in terms of those repeat units.Last,after using the traditional method of morphological operations,morphological opening is used again in order to remove noise and stand out the defects.A system by MATLAB is designed to emphatically detect the defects of hole,warp-lacking and weft-lacking.The reliability of morphological operations is tested based on experiments.
