摘要
阐述了逆向工程中自由曲面拟合的曲面重构和多个曲面整合两方面内容。曲面重构可分为插值和逼近两种方法,其中插值的方法有样条插值、基于散乱点数据的三角曲面插值;而逼近的方法有最小二乘逼近、基于能量原理的曲面逼近、偏微分方程逼近和小波理论的逼近方法等。则多个曲面整合包括几何连续性和参数连续性。本文对他们分别进行了介绍归类和比较,并且得出了有关的结论。
In this paper,the methods of free-form surface fit in reverse engineering are presented that include reconstraction and conformity of surface.Reconstraction of surface includes approach and insert. Thereinto, approach and insert have several ways respectively . While conformity of surface includes geometrical sequence and parameter sequence. In this text, the methods sre classified and compared, and there are correlative conclusions.
