随着用于3D采集的技术变得广泛可用,预计记录遗产文物的3D内容将变得越来越流行。然而,为了提供对这些内容的访问和创造性地使用这些内容,有必要解决访问方面的挑战。其中包括使用合适的元数据自动丰富3D内容,以便内容不会丢失。为了应对这些挑战,本文提出了研究开发技术,以支持文化遗产(CH)领域的3D内容的组织和可扩展性。这项研究利用了这样一个事实,即文物已设计了几个世纪的独特的设计风格。因此,人工制品的形状和装饰可以提供关于人工制品的历史的重要信息。这篇文章的主要贡献包括一个本体论,用于记录用装饰品(如建筑造型)装饰的文物的3D表示。此外,本文还提出了一种基于形状显着性的互补形状检索方法,以提高基于三维形状的工件语义信息的自动分类。这种方法是测试摄政时期的装饰线条在国内内部发现的集合。这些内容提供了一个丰富的数据集,可以在此基础上探索许多CH工件的共同问题,例如设计风格和装饰性装饰。
As technologies for 3D acquisition become widely available, it is expected that 3D content documenting heritage artifacts will become increasingly popular. Nevertheless, to provide access to and enable the creative use of this content, it is necessary to address the challenges to its access. These include the automatic enrichment of 3D content with suitable metadata so that content does not get lost. To address these challenges, this article presents research on developing technologies to support the organization and discoverability of 3D content in the Cultural Heritage (CH) domain. This research takes advantage of the fact that heritage artifacts have been designed throughout the centuries with distinctive design styles. Hence, the shape and the decoration of an artifact can provide significant information on the history of the artifact. The main contributions of this article include an ontology for documenting 3D representations of heritage artifacts decorated with ornaments such as architectural mouldings. In addition, the article presents a complementary shape retrieval method based on shape saliency to improve the automatic classification of the artifact’s semantic information based on its 3D shape. This method is tested on a collection of Regency ornament mouldings found in domestic interiors. This content provides a rich dataset on which to base the exploration of issues common to many CH artifacts, such as design styles and decorative ornament.
