基于数字高程模型和遥感影像的三维可视化

The 3D visualization based on digital elevation and remote sensing image

基于数字高程模型和遥感影像的三维可视化在城市规划、土地利用等领域扮演着愈来愈重要的角色,本文系统的介绍了从地形三维建模、遥感影像处理到地形三维可视化的整个过程,着重分析了各种地形三维建模方法的优缺点,并对影响建模速度的关键环节加以改进。

Based on digital elevation model and remote sensing image,3D visualization plays more and more important role in domains such as urban planning,land utilization,and so on.This article introduces the entire process from terrain 3D modeling,remote sensing image processing to terrain 3D visualization,emphatically analyzes the advantages and disadvantages of each kind of terrain 3D modeling method,and improves the modeling method.
