| 摘 要： | 三维建模是3D GIS中一项基本任务,其速度在一定程度上取决于纹理获取的速度.随着三维数字城市建设的推进,传统的相机拍照法已不能满足快速获取纹理的要求,为此,提出一种在3D场景中构建航片纹理库的方法,其核心问题是模型与航片间索引的建立和纹理信息的提取.基于3D GIS平台,对建库的核心问题进行分析与研究,并且通过设计算...

| Abstract: | The three-dimensional modeling is an essential task in 3D GIS,and its speed depends on the speed of capturing texture to some extent.With the further promoting of the construction of three-dimensional digital cities,the traditional method of taking photos with camera can not meet the requirements of fast getting texture,thus,this paper presents a method of constucting aerial photograph texture library in 3D scene,its core problems are indexing between models and aerial photographs and extracting texture inf... |
