图像处理技术在纤维素纤维纵向特征参数研究中的应用

The Application of Image Processing Technology to the Characteristic Parameters of Cellulose Fibers

动态阈值解决了获取的图像中亮度不匀、聚焦不完全的问题。依据交叉部分边缘像素点的特殊性并利用拟合曲线解决了纤维交叉的分离问题。用二次扫描的方法提高了纤维直径测量的精度,提出了纤维素纤维的自动识别的特征参数。

This paper introduces dynamic thresholding to deal with the problem of uneven light, unfocused area existed in the longitudinal image and solved the problem of crossed fiber on the basis of curve fitting and special intersection. The double-scanning algorithm enhances the accuracy of transverse scans of fibers and some effective characteristic parameters using in automatically identifying cellulose fiber were got.
