摘要
3维景观模型越来越广泛地应用于城市建设和管理之中,如何高效快速地构建城市3维景观模型成为一个关键技术问题。地形与地物分层建模法是城市3维景观模型重建领域中的一个热门方法,它采用地形数据叠加建筑物实体来构建3维景观。该方法已成功应用于惠州市3维建模,实践证明该方法建模速度快、操作简单、具有广阔的应用前景。
It is more and more important to use 3D landscape models to solve the problem of city＇s construction and management.How to reconstruct 3D landscape models of city with high speed and efficiency has become a key technology.Modeling the terrain and surface features separately is a pop way among the field of reconstructing 3D landscape models of city,which reconstructs 3D landscape based on terrain and buildings.This method has been used to reconstruct 3D landscape models of Huizhou city,which is proved to have a good foreground for it＇s high speed of modeling and simple operation.
