Interactive modelling tools for 3D building reconstruction

Fully automatic reconstruction of 3D city models is a topic of current research, while semi-automatic approaches are already applied for the acquisition of large databases. Examples for application areas are visualizations for architectural evaluation, town planning and city information systems as well as simulations for city climate, environmental evaluations and wave propagation. This paper reviews the available datasets and methods for efficient 3D reconstruction and some advancements that have been reported lately by the scientific community, focusing on interactive systems. Finally, the approach developed at the University of Stuttgart is presented and results of several projects are shown.
