摘要:
为了解决玻璃纤维织物在线检测效率低、实时性差等问题，提出了一种基于Blob分析的织物缺陷检测方法．首先对织物图像采用均值滤波器进行平滑处理，以削弱噪声和织物纹理的干扰，然后采用Otsu 算法寻找最佳阈值将图像分割为Blob和背景的像素集合，采用形态学处理调整分割后的Blob形状，最后对图像进行连通性分析和特征提取，通过对Blob区域进行最小外接矩形拟合得到缺陷特征的个数和尺寸等信息．实验结果表明:该方法计算简单、检测结果稳健可靠、实时性好．
Abstract:
In order to solve the problems，such as low efficiency，poor real-time performance and so on，in on－line detection of glass fiber fabric，a new method of fabric defect detection based on Blob analysis is proposed． Firstly，the image is smoothed by using mean filter，and the noises and the fabric textures are weakened． Then，the Otsu algorithm is used to find the best threshold to segment the image into Blob and background pixels． The shape of the Blob region is adjusted by using morphological processing． Finally，the connectivity analysis and feature extraction of the image are carried out． The number and size of the defects are obtained by using the least square fitting of the Blob region． Experimental results show that the method is simple，reliable and robust．
