摘要/Abstract

摘要： 本文探讨了利用图像处理技术测试较厚非织造材料纤维取向的方法。首先，利用多焦面图像融合技术获得超景深条件下材料的清晰显微图像；其次，利用边缘检测算子提取纤维的两条边缘线来表征纤维取向信息；最后，根据边界曲线积分原理，计算出融合图像中纤维段的切线角度的统计值，获取非织造材料0～180度取向分布曲线。将上述测试方法得到的结果与电镜图像人工取向测试及短隔距力学拉伸实验结果进行验证，证明这种新方法能够快速准确的测试非织造材料的取向。

关键词: 非织造材料, 纤维取向分布, 多图层图像融合, 边界曲线积分

Abstract: In this paper, the application of image processing technique for fiber orientation in thicker nonwovens was discussed. First, multi-focal image fusion was employed to capture sharp-focused images in the super depth of field. Secondly, boundary detector was used to extract fibers’ two edges indicating fiber orientation. Finally, fiber segments’ orientation angle was calculated using boundary integral algorithm. Finally, fiber orientation distribution within the range of 0 to 180 degree can be obtained. Results obtained using image fusion was verified by manually depicting fiber orientations in their SEMs. Meanwhile, short-span tensile tests were conducted to study relation between fiber orientation and materials’ mechanical orientation. Experimental results demonstrate that the new method is useful to measure fiber orientation in thicker nonwovens.

Key words: nonwovens, fiber orientation distribution, multi-focal image fusion, boundary curve integral
