| 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 base... |
