Rapid production of virtual reality city models

Description :
In the approach presented in this paper, the geometric reconstruction of urban areas is based on height data from airborne laser scanning and 2D GIS, which provides the ground plan geometry of buildings. Both data sources are used to estimate the type and parameter of basic primitives which in turn are combined to obtain complex building structures. The final output consists of 3D CAD models for the buildings. Using the reconstructed geometry, terrestrial images are mapped on to building façades to generate virtual city models. - (L'A.).
