摘    要:提出了对点云数据进行曲面拟合的一种新方法,它基于一类L20,1]上完备正交的函数系(称之为V-系统)。V-系统由分段多项式组成,它包括各个层次的间断函数,具有多分辨分析特性和局部性。给出了k次V-系统(k=0,1,2,3)的具体表达式;利用有限项Fourier-V级数展开式,高效地生成点云数据显示的被测量对象的几何造型。检测例子表明,这种方法对很广泛遇到的一类问题而言,处理过程简单、速度快、精度高。

关 键 词:完备正交函数系  点云  V-系统  多小波

Abstract:A novel approach to points cloud fitting was given.The work is based on a class of complete orthogonal k-degree polynomials in L20,1](called V-system).V-system which is composed of piecewise polynomials including every degree polynomials has advantageous properties of multi-resolution analysis and local.The expression of k-degree(k = 0,1,2,3) V-system was given,which effectively generated geometrical sculpt from surveying object displayed of points cloud by using limited number items of Fourier-V progression.The experimentations indicate that this approach has simple processing,fast calculating and high precision for some ordinary project.
Keywords:complete orthogonal function system  points cloud  V-system  multi-wavelet
