震后北川县城三维建模方法研究

摘要

Most houses of Beichuan collapsed or reduced to ruins because of Wenchuan earthquake, and it is hard to restore. This paper uses the 3d urban construction of Beichuan county as an example to discuss a method which reconstruct 3d models using DOM and artificially modeling, including buildings,ruins, roads, greening and other scenes after the earthquake.%汶川地震造成北川县城大部分房屋倒塌。本文以震后北川县城为例，在已有城市建模方法基础上，提出了基于航空影像与人工建模结合的震后建筑物、废墟、道路、绿化和小品的三维建模方法。
