在陶制文物的虚拟复原过程中，由于其本身质地、环境及人为因素等影响，文物碎片易受损缺失，基于断裂部位几何信息的传统拼接方法存在一定局限性。针对断裂部位缺损的陶制文物碎片，提出一种结合碎片表面纹理特征及断裂边界轮廓线的拼接方法：利用曲率确定潜在脊点，并用最小二乘法拟合，提取碎片表面纹理特征线；结合纹理形状边长及顶点角度信息进行纹元分析，构造破损纹理约束条件，实现初步匹配；将断裂边界轮廓角点集合中的相邻两点连接为弦，形成轮廓线弦长序列描述子，对轮廓线位置信息进行约束，得到最终匹配对。结果表明，此算法能实现断裂部位缺损陶制文物碎片的拼接，对具有显著纹理特征的碎片拼接具有一定的优越性。

In the process of restoration of ceramic artifacts, the fractured site is easy to be damaged due to its own characteristics, the environment, and man-made factors. The traditional stitching method based on geometric information of fracture location has some limitations. We propose a method of splicing of fractured sites combined with surface texture and boundary contour for the restoration of fragments of ceramic artifacts. Firstly, the potential ridge points are determined by the curvature and the least squares method is used to extract the texture features of the debris surface. Then, the texture elements are combined with the edge length and the vertex angle information to construct damaged texture constraints and realize preliminary matching. Two adjacent points in the boundary set of the contours are concatenated to form the contour chord sequence descriptor, and the contour position information is constrained to obtain the final matching pair. The results show that the proposed algorithm can achieve the splicing of broken artifact fragments, and it has certain advantages for the debris with obvious texture features.
