为改善手工测量方法的不足,提高测算的效率和精度,采用纱线形态扫描法测量织物中纱线的实际长度,从而计算织物的织缩率,并与传统的手工拆线法做比较.实验利用计算机图像处理技术结合Otsu基本原理对扫描图像进行二值化处理,然后使用计算软件MatLab对图像中提取出的数据进行函数拟合,最后采用定积分的方法计算出所获得的纱线扫描图中的曲线长度.结果表明:2种方法的测量结果非常吻合;纱线形态扫描法对织物中纱线的测定具有快速、简便和准确的特点.

To overcome the shortcomings of manual operation and improve the efficiency and accuracy of measurement, the actual length of the yarn was measured by yarn configuration scanning and the weaving shrinkage was calculated, which was compared with that by traditional manual measurement. In the experiment, combining Otsu basic principle with computer image processing technology, binarization processing was carried out. Then the extracted data from the image was fitted by using MatLab software. Finally, the curve length of the yarn in the scanning image was calculated by using definite integral method. The results demonstrated that the measurement results of the two methods are in good agreement, and the yarn configuration scanning method is faster, simpler and more accurate.
