摘要高保真信息三维建模方法是文物数字化保护中的重要研究内容,对于文物展示、研究、复原具有重要意义.本文以山东灵岩寺彩绘"牛呞比丘尊者"像为例,提出了一种面向造像类文物的高保真信息三维建模方法.首先应用三维扫描及多视图三维重建技术分别建立塑像的高精度几何三维模型和高分辨率纹理三维模型.然后,通过两种异源模型的相互配准和对齐,将纹理模型的高分辨率纹理自动映射至高精度几何模型表面,实现高精几何尺寸信息与高分辨率纹理信息的融合.本文提出的高保真信息三维建模方法基于成熟的商用软件和硬件,数据采集和处理高效、操作简单、成本低廉,对于造像类文物高效数字化存档具有实践意义. The 3D modeling method of high fidelity information is an important research content in the digital protection of cultural relics,which is of great significance to the display,research,and restoration.In this paper,a high fidelity information 3D modeling method for cultural relics was proposed based on the Niushi Buddhist monk statue in Lingyan Temple in Shandong Province.Firstly,3D scanning and multi-view 3D reconstruction techniques were used to establish the high precision geometric 3D model and high resolution texture 3D model respectively.Then,the high-resolution texture of the texture model was automatically mapped to the surface of the high precision geometry model through mutual registration and alignment of the two heterogeneous models,and realized the fusion of high precision geometry information and high resolution texture information.Based on mature commercial software and hardware,the cultural relics high fidelity information 3D modeling method proposed in this paper has the advantages of simple operation and low cost,which has practical significance for efficient digital archiving of cultural relics.
