为了得到高几何精度、高纹理分辨率的文物立体虚拟模型,助力文物的数字化保护,文中提出一种新的文物三维真实感虚拟模型构建方法,并且具体应用于纹理特征复杂的西夏陶瓷器。采用三维激光扫描仪获取点云数据,专业的单反相机获取纹理数据,结合Lightroom、Photoshop、Panorama Maker、Geomagic Studio、3ds MAX软件处理技术,构建西夏文物三维真实感虚拟模型重建机制,以白釉碗文物三维重建案例对所研究的关键技术进行说明。实验结果表明,该方法操作简单,可快速、批量地在PC端呈现西夏文物三维真实感虚拟模型,为建立文物三维真实感虚拟模型数据库、制定文物实际修复方案等提供借鉴方案。

In order to obtain stereoscopic virtual model of cultural relics with high geometric accuracy and high texture resolution,and promote the digital protection of cultural relics,a new method for constructing a 3D realistic virtual model of cultural relics is proposed,which has been applied to Xixia ceramics with complex texture features.The point cloud data of the cultural relic is obtained by a 3D⁃laser scanner,and the texture data of the cultural relic is obtained by a professional SLR camera.The processing technology combining the software of Lightroom,Photoshop,Panorama Maker,Geomagic Studio,3ds MAX,etc.is used to construct the reconstruction mechanism of the 3D realistic virtual model of Xixia cultural relics.The key technology studied in this paper is illustrated by the case of 3D reconstruction of a white⁃glazed bowl.The experimental results show that the method is easy to operate,and can quickly present 3D realistic virtual models of Xixia cultural relics on PC in bulk,which provides a reference scheme for establishing 3D realistic virtual model databases and making practical restoration scheme of cultural relics.
