摘要
三维数据模型正在成为数字图书馆中的重要信息,三维模型检索则是必须要解决的技术关键。本文较系统地介绍了该研究方向的现状,分析了其中的数据获取、特征提取、特征空间中的相似度量、相关反馈等关键技术。
D models are playing an important role in digital library and 3D model retrieval becomes a key problem.In this paper we systemically introduce the technical development situation in this area.And we discuss the key techniques for 3D data generation,feature extraction,similarity measure,relevance feedback.Future research directions are also be presented in this section.
