| 摘 要： | 针对织物中普遍存在的破洞、断经和缺纬三类疵点,提出了一种基于数学形态学的织物疵点检测方法.首先运用自相关函数和快速傅立叶变换找出织物经纬结构上的重复单元,然后以这些重复单元作为依据,运用形态处理学中的腐蚀背景法和膨胀目标法确定图像中的疵点信息,通过不同疵点样本对该方法进行仿真实验.运用该方法可使疵点识别率达到97%.实验结果证明该检测方法是可行的.

| Abstract: | In this paper, a method based on mathematical morphology is presented to detect fabric defects including hole, warp-lacking and weft-lacking. First, the fabric-structural 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. The experiments on the different kinds of defect samples show that the accuracy rate by this method can reach 97%, and proved its feasibility. |
