摘要：Virtual reality applications in the context of urban planning presume the acquisition of 3D urban models. Photo realism canonly be achieved if the geometry of buildings is represented by a detailed and accurate CAD model and if artificial textureor real world imagery is additionallymapped to the faces and roofs of the buildings. In the approach presented in this paperheight data provided by airborne laser scanning and existing ground plans of buildings are combined in order to enablean automatic data capture by the integration of these different types of information. Afterwards, virtual reality city modelsare generated by texture processing, i.e. by mapping of terrestrial images. Thus, the rapid acquisition of 3D urban GIS isfeasible.
