Automatic generation of Bayesian nets for 3D object recognition
B. Krebs, Friedrich M. Wahl · 2002
This paper proposes a general framework to build 3D object recognition systems from a set of CAD object definitions. Reliable features from object corners, edges and 3D rim curves are introduced; they provide sufficient information to allow identification and pose estimation of CAD designed industrial parts. The statistical properties of the data, caused by noise, is modeled by means of Bayesian nets, representing the relations between objects and observable features. This allows to identify objects by a combination of several features considering the significance of each single feature with respect to the object model base. On this basis robust and powerful 3D CAD based object recognition systems can be built.
