一种简便有效的曲面拟合方法及其成像技术

A SIMPLE AND EFFECTIVE METHOD OF SURFACE FIT AND IT'S TECHNIQUE OF IMAGE FORMATION

本文旨在论述一种新的、简便有效的曲面拟合方法,该方法是建立在拉格朗日三次曲线拟合方法之上,通过在x和y两个方向同时作曲线拟合,构成一个空间曲面。文中还讨论了该空间曲面的成像技术。经编程验证,此法具有计算量小,拟合精度高,拟合出的曲面光滑等优点,有很好的实用价值。

This paper develops a new method of surface fit being simple and effective.This method is based on the lagrange's third order curve fit method and curve fitting in x and y two direc- tions simultaneously.The graphics technique of space surface is discussed.This method of surface fitting are proved by programming on computer to be of small amount of computation higher precision and smoothness of the surface.Morover,it can be widly used in many fields.
