摘要
本文提出一种快速断面轮廓间插值方法。以给定分段点数轮廓多边形近似方法为基础,通过各对应多边形分段点间的线性插值,完成从一个断面轮廓到另一个断面轮廓的快速插值。文中给出了快速插值的结果,及使用该结果得到的一个人体器官三维显示的实例。
A fast interpolation method for cross-sectional contours is presented in this paper. Based on a polygonal approximation method that gets polygons with the same number of segment points,the fast interpolation from one contour to another can be realized by linear interpolation between each pair of segment points in two contours. The result is presented and the 3D display of an object from cross-sectional images is also realized.
