基于骨架和灰色关联分析相结合的机械零件三维模型检索
3D Model Retrieval of Mechanical Parts Based on Skeleton and Grey Correlation Analysis
摘要
Abstract
A 3D model retrieval method of mechanical parts was proposed combined skeleton and grey correlation analysis.Firstly,3D model of mechanical parts was simplified to get a coherence mod-el without hollow structure by ignoring additional features of model,such as fillet,chamfer and hole etc.Then the skeleton was extracted,which expressed shape and topology features of the parts model from simplified 3D model of mechanical parts based on the electric field method;and the skeleton was converted into characteristic curve.Finally,calculating the similarity degrees among characteristic curves and grey correlation analysis method was used to obtain similarity degrees of parts.Through the example verification and experimental analyses,the method can accurately retrieve the similar 3D model of mechanical parts.关键词
