摘　　要：应用计算机视觉的方法，提出了一种针对建筑物的、基于图像造型的方法，这种方法首先对建筑物进行射影重建，然后利用建筑物的表面特征完成欧氏重建并对结果进行了优化。从实验结果上看，该方法比较好地恢复了物体的三维信息，并且存在操作简单、需要附加信息较少的优点。In buildings reconstruction, the article applies the method of computer vision and suggests a way of image based modeling for buildings. The way reconstructs the buildings by projective reconstruction at first, and then makes use of the surface features of buildings to complete the Euclidean reconstruction and optimizes the results. In view of the results, the method recovers the 3-dimension information of the objects satisfactorily and has the advantages of simple operations and less additive information.
