利用高分辨率影像阴影重建建筑物三维模型的算法研究

Study on Algorithm to Reestablish Three-Dimensional Modeling for Buildings Using High-Resolute Image Shadow

城市建筑物三维模型的建立对城市规划、城市建设管理以及城市灾害评估等其他应用方面均有积极的意义,利用高分辨率影像建筑物阴影提取建筑物信息进而计算建筑物高度完成三维建模的方法,以其方便快捷、精度较高等优点越来越被研究者所关注;本文通过对该方法基本原理及算法的叙述,以求能够对遥感图像中建筑物信息提取方法有更深层次的认识并熟练应用。

Three dimensional model establishment of urban buildings plays important role in urban planning , management and disaster evaluation.The three dimensional modeling achieved by computation of the building height concerns more and more researchers by u -sing high-result image shadow for its being rapid and accurate .The paper introduces the basic principles and application of this method .
