Geometry-based similarity retrieval of rotational parts

摘要

In available retrieval and classification systems, parts arendescribed using attributes comparable to those in traditional databasensystems. The authors suggest a system for retrieval of parts havingngeometric similarity which accesses a database system storing thengeometric data provided by the CAD system. By maintaining, storing andnmanipulating the complete geometric information of objects, the approachnleads to great flexibility and efficiency for similarity and othernqueries
