摘要 在稀疏数据的三维表面重建中,通过插值的方法得到更为稠密的数据点是一个很重要的环节。该文在比较其它插值算法的基础上,提出了一种三维表面重建算法。该算法在对原始数据进行Delaunay三角剖分的基础上采用二维高斯小波函数插值,它不仅能有效地处理非均匀采样的三维稀疏数据,而且能克服其它插值算法中需要定义权重或估计参数的缺点。最终的实验结果验证了该算法的有效性和实用性。 In constructing3D(three dimensional)surface from the spare points,it is very important to construct a dense data of control point by interpolation.In the paper,a new algorithm of reconstructing3D(three dimensional)surface is presented.The method can effectually process3D coarse sample data with un -equal spacing and overcome the disadvantage that the other methods must define the weight and parameter of interpolation,due to Delaunay Triangulation and2D Gauss wavelet function interpolation adopted.The corroborating experimental results are also given.
