Knowledge-Based Search Engine for Specific 3D Models

Abstract

A search engine is implemented to support querying specific 3D models - digitized Indian pottery on Internet for scientists. The engine is knowledge-based. I.e. not only shape information but also shape feature information (knowledge) of 3D models can be retrieved via the engine. Shape information of 3D models is collected from Lasers Scanner and/or geometric modeling techniques. Feature information is generated from shape information via feature extracting techniques. All information is organized according to a prior defined XML schema. Matching algorithm, which is the key challenge of search engine design, is also presented. One of applications of this search engine for 3D objects is a retrieval system of Native American ceramic vessels for archaeologists. © Springer-Verlag 2004.
