A Method for Determining the Key Structure of 3D Parts Based on Rough Set and Concept Lattice
Authors: , ,
Abstract: The key of parts model retrieval is how to complete the similarity calculation as quickly and accurately as possible. The similarity calculation is closely related to the model feature extraction. Concept lattice is a powerful tool in knowledge processing and analyzing, its reduction can improve the efficiency. In this paper, by mapping relationships among the parts functional surfaces and the positions to the binary formal context, a concept lattice of 3D parts structure model was built, authors use discernibility matrix of rough set in simplifying the concept lattice of formal context based on parts assemble structure, and then quickly determine the key structure to reflect the characteristics of the parts, which has very strong regularity and lays the basis for the efficient parts query.
