基于航空立体影像对的复杂房屋三维拓扑重建

3D Topological Reconstruction of Complicated Buildings

    摘要
  • 摘要: 对利用航空影像对重建复杂房屋三维模型进行了研究,提出了拓扑链、外拓扑和内拓扑的概念,分析了复杂房屋的内拓扑和外拓扑的三维重建,构造了复杂房屋的三维拓扑数据模型。基于此模型设计了双向搜索算法,用于自动构建复杂房屋的三维拓扑面,从而实现了复杂房屋的自动三维拓扑重建。实验证明,本文提出的双向搜索算法是很稳健、高效的。

     

    Abstract: This paper tries to research 3D reconstruction of complicated buildings based on stereo aerial images. Three important concepts, topological chain, interior topology and exterior topology, are put forward. The reconstruction of interior topology and exterior topology is analyzed, and the topological data model of complicated buildings is developed. Based on this data model, a bi-directional querying algorithm is designed to reconstruct surfaces of complicated buildings automatically.
