Use of explicit knowledge for the reconstruction of 3-D object geometry
The automated generation of 3D CAD models of real objects from different camera views poses frequently problems in regard to man made objects. Models do not match the expectations of a human observer, because house walls are not perpendicular, streets are not planar, windows and doors are not rectangular, etc. The new knowledge based modeling system AIDA handles these problems by using an explicit knowledge base about the semantics of the scene to be modeled including knowledge about the visual appearance of scene objects. During the analysis of the scene constraints for the modeling are derived automatically and are applied during model generation.
