摘要:

在网络上使用或存储在数据库中的3D模型的大小变得越来越高。然后,一种有效的方法,允许用户找到类似的3D对象为给定的3D模型查询已成为必要的。关键词和三维模型的几何形状不包含语义信息,不能满足用户检索的需要。提出了一种结合语义概念和形状索引的三维模型检索方法。为了获得这些概念,我们使用机器学习的方法来标记三维模型的k-means算法在措施和形状指标空间。此外,语义概念已组织和表示的本体语言OWL和空间关系被用来消除歧义之间的模型相似的外观。SPARQL查询语言已被用来质疑在这种语言中显示的信息,并计算两个3D模型之间的相似性。我们解释我们的结果使用普林斯顿形状基准数据库和结果显示的性能所提出的新方法来检索3D模型。关键词:三维模型,三维检索,度量,形状索引,语义,本体

英文摘要:

The size of 3D models used on the web or stored in databases is becoming increasingly high. Then, an efficient method that allows users to find similar 3D objects for a given 3D model query has become necessary. Keywords and the geometry of a 3D model cannot meet the needs of users' retrieval because they do not include the semantic information. In this paper, a new method has been proposed to 3D models retrieval using semantic concepts combined with shape indexes. To obtain these concepts, we use the machine learning methods to label 3D models by k-means algorithm in measures and shape indexes space. Moreover, semantic concepts have been organized and represented by ontology language OWL and spatial relationships are used to disambiguate among models of similar appearance. The SPARQL query language has been used to question the information displayed in this language and to compute the similarity between two 3D models. We interpret our results using the Princeton Shape Benchmark Database and the results show the performance of the proposed new approach to retrieval 3D models. Keywords: 3D Model, 3D retrieval, measures, shape indexes, semantic, ontology
