摘要
提出了一种聚类—混合整数优化方法,能实现模型快速自动单体化,解决倾斜三维模型数据量大、应用范围受限的问题。利用倾斜摄影三维模型建筑物的连接性,经聚类分析后,可达到建筑物分离的目的,再根据建筑物水平和垂直的特性对分离出来的建筑物进行立面自动提取,采用混合整数优化法构建体模型,实现三维模型的单体化。实验结果表明,此方法能达到预期目标,且效果比较理想。
In this paper,a clustering mixed integer optimization method is proposed to realize the rapid and automatic monomer of model and solve the problem of large data volume and limited application range in oblique 3D models.Firstly,by utilizing the connectivity of oblique photography 3D model buildings and conducting cluster analysis,the goal of building separation can be achieved.Then,based on the horizontal and vertical characteristics of the buildings,the separated buildings are automatically extracted for facades.Finally,a mixed integer optimization method is used to construct the volume model,achieving the monomer of 3D model.The experimental results show that the method can achieve the expected goal and its effect is good.
