3D Technologies

Alexandria

Alexandria is a state-of-the-art solution for 3D object databases.

Alexandria is a 3D management system that automatically describes the shape and the colour distribution of 3D objects by applying sophisticated techniques in order to capture the most important features in an incredibly compact descriptor or index. Alexandria can search the descriptor database in almost no time in order to retrieve similar 3D objects according to shape and colour by applying a content-based approach and the query-by-example paradigm.

Alexandria is based on a proprietary patented technology and is foreseen for applications like CAD databases, inspection, 3D information retrieval and 3D catalogues. For instance, one can search a CAD database in order to find similar designs, or a museum database, in order to find an artefact of a given style or period. This visually intuitive, language-independent query system empowers the user to base his query on the entirety of the multimedia content, not only on an incomplete text description as in most traditional approaches. Alexandria is currently applied in the field of anthropometry in the framework of the CAESAR™ Project.

The project Alexandria began in January 1998, and is part of IIT-VIT’s ongoing research to provide scientific technologies and techniques to collaborative partners in other disciplines by employing its expertise in visual sensing and processing.

IIT-VIT has been able to develop useful patented technology for content-based management and retrieval of 3D models in collaboration with such partners as:

the CAESAR™ Consortium (Lockheed Martin Aeronautical, Magna Interior Systems Engineering, Mazda North American Operations, Mitsubishi Motors Corporation, NIOSH, Nissan Motor Co., Ltd., etc),
University of Pretoria (South Africa)
SITE (University of Ottawa)
