| 摘 要： | 彩塑三维重建是精确获取文物的三维几何和纹理信息的数字化技术,对于文物保护、数字档案建立、考古研究、展览展示以及移动数字博物馆建设等都具有重要的意义。莫高窟彩塑作为一种不可移动文物,受采集空间及丰富的纹理信息的影响,现有的三维重建方法尚不能在保证重建精度的基础上,准确还原文物表面的色彩信息。为此,通过研究和设计双相机结构光的FOTOMOULD三维重建系统,对莫高窟第45窟彩塑菩萨三维重建,在获取高精度几何信息的同时,达到了色彩、纹理、细节等高度还原的效果。

| Abstract: | D reconstruction is a digital technology used to acquire both three-dimensional geometric and texture information about cultural relics, and is of great significance for the conservation of cultural relics, establishment of digital archives, archaeological research, exhibition and mobile digital museum construction. This technique is of use for the study of immovable painted grotto sculptures. Such a sculpture is influenced by acquisition space and is rich in texture information. Existing 3D reconstruction methods cannot recover the exact color information on the surface of cultural relics while maintaining high reconstruction precision. Using the FOTOMOULD 3D reconstruction system, with dual-camera structured light, a 3D reconstruction of a painted Bodhisattva in Cave No.45 of Mogao Grottoes was carried out, yielding high-precision geometric information as well as information on color, texture and other details. |
