针灸铜人三维可视化研究与应用

针灸铜人是中国古代医学珍贵的艺术品,具有重要的文化和艺术价值。针对针灸铜人等文化遗产数字化保护手段传统单一,体验性差和传播力不强等问题,本文综合利用三维激光扫描、三维可视化和虚拟现实等技术提出了一种新的数字化方法。以湖北省博物馆珍藏的腧穴针灸铜人为对象,首先采用三维激光扫描技术进行数据采集和模型构建,然后利用XML语言对其承载的传统中医知识进行表示与存储；其次,基于改进的二次误差度量和递进网格算法实现了铜人多分辨率简化模型的自动生成；最后,基于Unity引擎开发了一套针灸铜人虚拟交互展示系统,实现了穴位、经络和常见疾病等传统中医知识在三维虚拟场景下的可视化展示与交互查询。本文提出的方法可以为历史文物与非物质文化遗产的数字化保护与传播提供借鉴。

The research and application of 3D visualization for bronze acupuncture figure

Bronze acupuncture figure is a precious art in ancient Chinese medicine, which has important cultural and artistic value. However, the traditional protection of this kind of cultural heritage focuses on text, pictures, and video, leading to poor user experience and dissemination. In this paper, a new approach of digitalization is proposed by using three dimensional (3D) laser scanning, 3D visualization and virtual reality. Taking the bronze acupuncture figure with acupoints collected by Hubei Provincial Museum as an example, 3D laser scanning technology was firstly applied to capture 3D point cloud data of it. Secondly, knowledge models of traditional Chinese medicine were represented and stored by using eXtensible Markup Language (XML). Thirdly, a mesh simplification algorithm based on modified quadric error metric and progressive mesh construction was proposed to automatically generate multiresolution 3D models. Finally, a Unity engine based virtual and interactive system for bronze acupuncture figure was developed, which provided the visualization and query of acupoints, meridians and common diseases in 3D virtual environment. The proposed method is able to provide a reference solution for the digital protection and dissemination of historical relics and intangible cultural heritage.
