The information of crystal structure and orientation can be provided by analysing the EBSD (electron backscatter diffraction) patterns which are obtained with the EBSD devices. The reliability and accuracy of the information relies on the location of bands and intersections of the EBSD patterns. In this study, a method is proposed to automatically obtain the locations and intersections of the EBSD patterns, that is, Kikuchi bands. The proposed method uses Radon transform and progressive probabilistic Hough transform to detect straight lines and line segments of the Kikuchi band edges, respectively. Then, Kikuchi bands can be presented by fitting the hyperbolas with the endpoints of line segments. The results can numerically describe the information of Kikuchi bands. Experimental results show that the method is robust and can detect more accurate Kikuchi bands and intersections.

基于Radon变换和PPHT的菊池波段自动检测

通过分析 EBSD 设备获得的 EBSD（电子背散射衍射）图案，可以提供晶体结构和取向的信息。信息的可靠性和准确性取决于波段的位置和 EBSD 模式的交叉点。在这项研究中，提出了一种自动获取 EBSD 模式的位置和交点的方法，即菊池波段。所提出的方法使用 Radon 变换和渐进概率 Hough 变换分别检测菊池带边缘的直线和线段。然后，可以通过将双曲线与线段的端点拟合来呈现菊池带。结果可以数值描述菊池带的信息。
