摘要
基于内容的三维模型检索正逐渐成为研究的热点。三维模型描述方式的多样性使三维模型在互联网上实现检索变得困难,采用XML方式描述三维模型可以有效地解决这一问题。探讨了XML方式描述的三维模型的基于内容的检索技术,论述了三维模型检索的原理和系统框架,对其中涉及的关键技术进行了详细的讨论,内容包括三维模型数据结构、三维模型的XML描述方式、三维模型规范化预处理、特征提取、索引建立、相似性匹配以及检索界面的设计。
Content-based 3D model retrieval is becoming the hotspot. The diversity of the way in which the 3D model is described makes it very difficult to retrieve 3D model in Internet. Describing the 3D model in XML can solve the difficulty effectively. The content-based retrieval technology o.f 3D model described in XML is discussed. After introducing the principle and the system framework of the 3D mode retrieval, the primary key techniques of content-based 3D model retrieval are analyzed, including the data structure, the way of describing the 3D model in XML, the normalization by preprocessing, the feature extraction, the building of index, the similarity measurement and the design of user interface.
