Abstract
For generating a 3D geometric model () and/or a definition of the 3D geometric model from a single digital image of a building facade (), a facade structure is detected from the digital image by dividing the facade () along horizontal lines into horizontal layers representative of floors (), and by dividing the horizontal layers along vertical lines into tiles (). The tiles () are further subdivided into a hierarchy of rectangular image regions (). 3D architectural objects () corresponding to the image regions () are determined in an architectural element library. The 3D geometric model () or the definition of the 3D geometric model is generated based on the facade structure, the hierarchy and the 3D architectural objects (). The library-based generation of the 3D geometric model makes it possible to enhance simple textured building models constructed from aerial images and/or ground-based photographs.
