摘要

将基于模型的重建方法应用于近景图像中建筑物的详细重建。利用鲁棒回归算法将图像匹配得到的三维点分割成一个粗糙的多面体模型，然后利用预定义的形状模板对该模型的几何形状进行细化，从而自动恢复出一个类似cad的建筑表面模型。对三维形状模板进行重投影，使其参数与图像信息最优拟合。本文在实际数据集上对所研究的方法进行了验证。

A model-based method for building reconstruction

Model-based reconstruction methods are applied to the detailed reconstruction of buildings from close-range images. The 3D points obtained through image matching are segmented into a coarse polyhedral model with a robust regression algorithm, then the geometry of this model is refined with predefined shape templates in order to automatically recover a CAD-like model of the building surface. Reprojection of the 3D shape templates is used to optimally fit their parameters to the image information. Throughout the paper the investigated methods are demonstrated on real datasets.
