Automatic 3-D building reconstruction is the key technology of "digital city" construction, which can be widely used in
urban planning and management. In this paper, we firstly analyze the disadvantages in traditional automatic building
reconstruction methods, and then according to characteristics of complex buildings, which is multi-storey and non-flattopped,
a new automatic building reconstruction method is proposed, which can solve the complex building
reconstruction problem effectively and conveniently. The reconstruction experiments show that the proposed method has
excellent universality, besides a small calculating amount compared with traditional methods.
