We propose a model-based approach to automated 3d extraction of buildings from aerial images. We focus on a reconstruction strategy that is not restricted to a small class of buildings. Therefore, we employ a generic modeling approach which relies on the well-defined combination of building part models, Building parts are classified by their roof type. Starting from low-level image features we combine data-driven and model-driven processes within a multilevel aggregation hierarchy, thereby using a tight coupling of 2d image and 3d object modeling and processing, ending up in complex 3d building estimations of shape and location, due to the explicit representation of well-defined processing states in terms of model-based2d and 3ddescriptions at all levels of modeling anddata aggregation, our approach reveals a great potential for reliable building extraction.
