基于点云和高清影像数据的文化遗产多分辨率三维重建

以不同类型的文化遗产为研究对象,提出了基于点云和高清影像数据的文化遗产多分辨率三维重建方法。该方法首先阐述了基于三维点云和高清影像数据的文化遗产三维重建的流程,然后提出了一种基于地理位置的不同分辨率遗址文物模型融合与展示方法。本文将该方法用于世界文化遗产——唐崖土司城遗址的虚拟展示,按照文物虚拟化方法精细重建了石人、石马、牌坊等文物模型,并且实现了文物模型和遗址模型的融合展示。

3D Model Multi-scale Reconstruction Based on Cloud Point and HD Video

In this paper, we propose a 3D model reconstruction for different types of cultural heritage based on cloud point and HD video. The three-dimensional reconstruction technology with multi-resolution on the basis of three-dimensional point cloud and high definition image data is described firstly. Then, we describe the method of cultural relics model fusion and display based on location. In this paper, the proposed method is employed to display of Tangya Tusi castle ruins which is the world' s cultural heritage. Shiren, shima, arches and other relic' s model were rebuilt according to the fine cultural relics virtual reconstruction method. Through model fusion the multi-resolution digital presentation for Tangya Tusi castle ruins was completed.
