摘    要:本文采用特征点匹配的方法,先由二维视力获取三维空间的点和曲线,然后经过一系列线性运算得出三维曲面。本算法可对任意二次曲面进行三维重建,不仅对曲面的空间摆放沿有限制,而且对曲面自身的对称性也无要求。因此,可将重建对象扩展为圆柱、椭圆柱、球、椭球、双曲面、抛物面等。本文给出的算例表明了算法的有效性。

关 键 词:三维重建  工程视图  任意二次曲面  计算机制图

Abstract:This paper presents a novel algorithm, which employs the character point matching approach to obtain the points and curves in 3D space from 2D orthographic views ,and then constructs the 3D quadratic surface through linear calculations. This algorithm can be applied to the reconstruction of arbitrary quadratic surfaces. No restriction has necessarily been put on the position, direction, as well as the symmetry for the curved surfaces to be reconstructed. Therefore, the types of reconstructable curved surfaces have been greatly extended by this method. A numerical example is also given in this paper,demonstrating the feasibility and reliability of this algorithm.
Keywords:D reconstruction  Orthographic views  Quadratic surface  Character point
