摘要: 研究了工业CT图像序列中工件内部管道的拟合方法。在利用Facet模型提取管道边缘的基础上,将三维圆柱面、椭圆柱面管道的拟合转化为中心轴截面上的二维轮廓曲线圆、椭圆的拟合,与传统的三维曲面拟合相比,效率更高。通过对实际的发动机工业CT图像进行实验,结果表明该方法可以较准确地获取工件内部管道的几何参数,为基于工业CT的逆向工程打下基础。

Abstract: A fitting of industrial CT image sequences work’s pipes is studied.Based on edge extraction of Facet model,this method makes three-dimensional cylindrical,elliptical cylindrical pipe fittings be turned into the central axis of the cross-section of two-dimensional curve(circle or ellipse) fittings.Compared with the traditional three-dimensional surface fitting,it is more efficient.Test of the actual engine CT images shows that this method can be used for the acquisition of pipelines’ geometric parameters based on industrial CT images,so this method lays the foundation for reverse engineering based on ICT images.

Key words: industrial CT, Facet edge extraction, reverse, pipeline, image fitting
