摘要
对城市三维模型的LOD分级进行了简单介绍,然后利用高分辨率卫星立体影像,分别采用立体测图、自动构建、建筑轮廓矢量+自动构建3种方法进行城市三维模型(LOD1.3级)快速构建试验,分析了试验结果,在此基础上给出了基于高分辨率卫星立体影像的城市三维模型(LOD1.3级)快速构建方法.
Abstract
In this paper,the LOD classification of three dimensional city models is briefly introduced,and then based on high resolu-tion satellite stereoscopic images,experiment on rapid construction of three dimensional city models (LOD1.3) is carried out by using three methods:stereo mapping,automatic construction,building outline vector+automatic construction,the experimental results are analyzed,and on this basis,suggestions are given for the rapid construction of three dimensional city models (LOD1.3) based on high-resolution satellite stereo images.
