Abstract :
A new method is introduced for the reconstruction of 3D building structures using single-view 2D image with controlling objects setup in Google Earth. The method is based on the theory of projective geometry and the aid of GE which provides means that make it possible to set controlling objects possible. Two types of building structures and their variations and combinations could be reconstructed. It is shown that the accuracy of the reconstruction is satisfactory based on observations of some test cases. The ray tracing method is used to calculate the received power in five routes in Rosslyn, VA. Comparison with the path gain obtained using a more accurate city model shows that the new model provides good results. More details and examples will be provided in the presentation.
