| 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,本文提出了一种基于高分辨率航片的无遮挡影像获取算法,并设计出选取理想航片的算法,实现了纹理自动匹配,对快速建模具有重要意义.

| Abstract: | 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 presented an algorithm of capturing non-blocking images based on high-resolution aerial photos,designed the algorithm for choosing ideal aerial photo,and realized automatic textu... |
