三维模型检索的效果取决于三维模型的特征提取子的优劣,本文解释了三维模型检索领域的关键概念,并且着重介绍了基于统计的特征提取子、基于拓扑结构的特征提取子、基于几何结构的特征提取子以及基于视觉特征的提取子
这些提取子在某些应用中取得良好效果的同时,也存在着无法跨越“语义鸿沟”的问题,文章最后针对语义检索的典型方法进行了介绍

） Abstract： In the wave of informationization, three-dimensions modeling technics have deeply changed our life
3-D model retrieval as one of the key technics in three-dimensions modeling, has been widely applied in the fields like computer-aided design, face recognition and match, bioinformatics, and so on
The efficiency of 3-D model retrieval depends on the quality of feature descriptors for 3-D models
While explaining the core concepts in the field of 3-D model retrieval, this article emphatically introduce the distribution-based descriptor, topology-based descriptor, geometry-based descriptor, and view-based descriptor
These descriptors on the one hand have achieved good results in some applications, on the other hand also meet the problem of ``semantic gap''
The last part of the article give a description to the typical methods in semantic retrieval
