残损古陶瓷器三维数字化重建方法研究进展

Research Progress in Three-dimensional Digital Reconstruction Methods of Damaged Ancient Ceramic Artifacts

研究古陶瓷器三维数字化重建,对于珍贵但残缺的器物的修复、大量残片拼接与器物的复原都具有十分重要的意义。综述了近十年来残损古陶瓷器三维数字化重建原理和方法的研究进展,主要包括迭代匹配法、边缘曲线拟合法、虚拟轮廓法、轴线定位法以及剖面厚度拟合法。结合古陶瓷三维数字化重建过程中的实际问题,分析了各种方法的适用场景,提出了对于单一器物残片的确认思路。未来,对于古陶瓷器的数字化重建,还需要考虑到不同器物数字模型的精度和可视化展示。

Three-dimensional digital reconstruction of ancient ceramic artifacts is of great significance for the repair of precious damaged objects and assembly of numerous fragments and the restoration of artifacts.This paper is aimed to provide an overview of research progress in the principles and methods of three-dimensional digital reconstruction of damaged ancient ceramics over the past decade,including iterative matching,edge curve fitting,virtual contouring,axis positioning and profile thickness fitting.Combining practical problems encountered during the three-dimensional digital reconstruction process of ancient ceramics,this paper analyzes the applicability of each method and proposes an approach for confirming individual artifact fragments.In the future,the accuracy and visualization of digital models of different artifacts must also be considered for the three-dimensional digital reconstruction of ancient ceramics.
