摘　　要：针对三维纤维微观结构方向检测的不足,提出一种基于facet模型的三维纤维方向检测方法。该方法将三维纤维方向检测转换为二维平面检测,能够降低计算的复杂度,通过facet模型实现了不同直径纤维方向的精确检测,模型窗口尺寸略大于纤维直径时能达到最优结果。实验结果表明,所提方法可快速准确地获取不同直径的三维纤维方向数据,优于现有的典型算法。Orientation detection is not considerably performed for describing the microstructures of three- dimensional (3D) fibers. Therefore, a novel 3D fiber orientation detection method is proposed based on a facet model for converting the 3D fiber orientation detection into two-dimensional (2D) plane detection, reducing the computational complexity and realizing the accurate detection of different diameter fiber orientations. The size of the model window should be slightly larger than the fiber diameter for obtaining the optimal results. The experimental results denote that the proposed method is more accurate and fast when compared with the existing typical algorithms at obtaining the 3D fiber orientation data in case of different diameters.
