Abstract

We compare computational results for three procedures for reconstruction and texturing of 3D urban terrain. One procedure is based on recently developed “L1 splines”, another on conventional splines and a third on “α-shapes”. Computational results generated from optical images of a model house and of the Gottesaue Palace in Karlsruhe, Germany are presented. These comparisons indicate that the L1-spline-based procedure produces textured reconstructions that are superior to those produced by the conventional-spline-based procedure and the α-shapes-based procedure.
基于L1样条、常规样条和Alpha形状的三维城市地形重建和纹理比较
比较了三维城市地形重建和纹理化的三种方法的计算结果。一个程序是基于最近发展的“L1样条”,另一个是基于传统的样条,第三个是基于“α-形状”。计算结果产生的光学图像的样板房和Gottesaue宫在卡尔斯鲁厄,德国。这些比较表明,基于l1样条的方法产生的纹理重建效果优于传统的基于样条的方法和基于α-形状的方法。
