.... tasks, especially for controlling industrial processes (cf. Hansen and Henderson 1993, Flynn and Jain 1991, Ikeuchi and Flynn 1995, Munkelt 1995) The use of CAD models in building extraction is therefore restricted to the identification of a priori known buildings (cf. Sester and Forstner 1989, Schickler 1993, Huertas et al. 1995) Generic modeling approaches promise on the one hand the greatest modeling power, but on the other hand demand effective constraints and heuristics to restrict modeling to building specific shapes.

....in terms of simple primitive shapes. Therefore parametrized models describing the most common building types suggest to be a promising tool for a pragmatic solution. Motivated by the research results of Quam and Strat 1991 this approach is used within the semi automatic system of Lang and Schickler 1993: the three dimensional building extraction consists in the selection of a basic building type model, its projection into the digital image, followed by a coarse interactive adjustment of the form and position parameters of the model and an automatic fitting based on extracted intensity edges from ....
....suited for controlling industrial processes where only certain well known objects like product or workpieces must be identified. Therefore the use of CAD models within the building extraction task is promosing for the search of a priori known buildings (F orstner and Sester 1989, Schickler 1992, Schickler 1993); the lack of variability makes it much more difficult to use CAD models for the extraction of unknown and complex buildings. 2.4 Generic Models for Object Recognition A recommendable survey about methods for three dimensional object recognition and reconstruction is given in Suetens et al. ....
