In view of existing hairiness and scratch in the yarn black board,through some methods such as smoothness processing,threshold value division and image repairing,can come up with a clear digital image without noise points and exactly measure the yarn diameter.
通过与纱线的实际直径对比得知,所采用的图像处理方法计算出来的纱线直径与实测直径一致,证明利用该图像处理方法所测得的纱线直径不失真,且能够准确反映纱线的外观特征,如粗节、细节、棉结等,为纱线黑板自动化评定提供了参考。
In this paper,we analyze development and defects of image processing techniques and provide some recognition algorithms to detect the structural parameter in woven fabrics,such as warp and weft densities,yarn diameter,linear density of the yarn and yarn twist angles using Digital Image Processing and realize automatically function of system with mixed program VB and MATLAB.
