基于本体语义分析的三维文物模型检索

Ontology-based 3D Cultural Relics Retrieval

随着互联网和计算机图形图像技术的迅猛发展,以三维模型为主要展现方式的多媒体资源数量呈现井喷式的增长,这不仅归因于三维模型具有更丰富的展现力,同时还弥补了图像和视频等多媒体资源在信息共享、存储、展示等多方面的不足。针对文物数字化保护领域中三维模型海量增长所带来的模型管理和检索等问题,提出了基于本体语义分析的三维文物模型快速检索方法。首先,对三维文物模型进行分类,构建针对文物领域的本体,建立模型的属性信息以及构建文物分类概念之间的关系;其次,根据本体之间的属性关系,建立该领域的相关推理规则,形成文物保护领域的语义网络;再次,利用本体语义信息以及本体之间的关联关系,生成本体信息之间的语义推理系统;最后,基于上述工作基础完成文物三维模型的快速、准确检索。实验结果表明,该方法在检索结果的查准率和查全率方面较传统检索方法达到了更好的效果。

With the rapid development of the Internet and computer graphics technology, the number of the multimedia resources which mainly uses 3D models to exhibit has a sharp growth. This is not only attributed to the rich show force of the 3D models, but also compensates the disadvantages of image and video multimedia resources such as information sharing, storage, and display. For model management and retrieval, and other issues brought about by the massive growth of 3D model in the field of digital preservation of cultural relics, a method of ontology-based 3D relics model retrieval was proposed. First, the 3D models were classified, and the attribute information of the model and the relationship between the concept of cultural relics were built. Second, the relationship between the ontologies was used to establish the rules and the semantic network. Third, the semantic ontology reasoning system was generated. Last, the system for quick and accurate retrieval of the 3D models was implemented. The experimental results show that the proposed method achieves better results than traditional methods.
