Abstract: Because the reqirement of the 3D model retrieval’s recall rate and precision rate is rising,while studying the overall features of models,the research on local features is more and more.In this paper,some popular methods of extracting the local features of models are analyzed and investigated,the method of local distinctive regions is studied and analyzed.The experiment results show that the use of local features can improve the recall rate and precision rate of the three-dimensional model retrieval.

Key words: local distinctive regions, 3D model retrieval, local feature

摘要: 由于对三维模型检索查全率与查准率的要求不断提高,在研究模型整体特征的同时,对于模型局部特征的研究越来越多。分析并讨论了几种主流的局部特征提取方法,深入研究了局部区分区域方法,并对此方法做出了改进以适应检索需求,经过试验证明,使用局部区分区域可以提高三维模型检索的查全率和查准率。
