Abstract: The urban street is a primary component of the city as one's intuitionistic impression on the city is coming from it.Hence,it is very significant for 3D city modeling(3DCM) to rapidly realize 3D visualizations of the street sight.Accordingly,the research on rapidly realizing 3D visualizations for the street sight combined the vehicle-based image sequence with 2D vector map is presented.The algorithms proposed were verified by experiments on real data sets.
