Abstract :
To perform the image-based modeling (IBM) procedure, the parameters, such as camera focus and principal point, are always needed by user input or by complicated calculation. A new computer vision based IBM method for building reconstruction is presented in this paper. It reconstructs the building models 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 experiment results, the method recovers the 3-dimension information of the objects satisfactorily and has the advantages of simple operations and less additive information needed.
