In many case the building data are not complete or they are missing. Due to this reason the capture and update of this data is required. As the tasks are expensive, automation will help to reduce costs. This dissertation discusses the automatic reconstruction of the topology of buildings from qualitatively described three-dimensional structures. Starting point are corners of buildings, extracted on a stereo based analysis. The corners as well as their mutual relations are classified qualitatively. We present an algorithm that connects the corners to buildings. The result can then be used for a quantitative reconstruction. The exclusive use of qualitative description of three-dimensional structures for the reconstruction of the topology is a new approach. The majority of known algorithms are using numerical and statistical methods. The advantage of the qualitative framework lies in a reduction of the number of solutions in contrast numerical methods. Topological reconstruction uses geometrical informations and relations between the corners. Such are i.e. the collinearity of corner edges, the coplanarity of planes or orientation information of edges of the form the edge directs up-left. The framework contains steps for the connection of the corner edges, the reconstruction of the building planes and the consistency verification of intermediate results. A partial reconstruction of the building is done if corners are missing. The methodology transfers known methods from mathematics especially analytic geometry to a new qualitative framework. The framework and the qualitative descriptions show that qualitative reasoning are in principle suitable for building extraction.
