Abstract

The generation of 3D model for buildings and crossroads presents a challenge due to the complexity of manmade objects and lack of image understanding algorithms. In this paper, a topological strategy for semi-automatic 3D reconstruction of complicated buildings and crossroads from aerial image pair is presented based on a topology-based 3D data model in which data collection and data modeling are merged into an organic whole. Finally, a prototype software system is developed to prove the validity of the presented approach.
