由于各种原因，文物往往会遭到破坏和残缺。为了帮助考古研究，我们提出了一种同时恢复一组相似物体的原始形状的新方法。基于相似形状近似线性相关的假设，我们使用矩阵恢复技术来实现复原。为了以矩阵形式表示输入形状，通过堆叠由使用非刚性变形的表面匹配方案生成的密集对应点的坐标来执行每个对准样本的矢量化。对巴永的人脸雕塑进行了3D扫描实验，实验结果验证了该方法的可行性和有效性。
Cultural relics are often damaged and incomplete due to various reasons. For the purpose of helping archaeological studies, we present a novel method for simultaneously restoring the original shapes of a group of similar objects. Based on the assumption that similar shapes are approximately linearly correlated, we use a matrix recovery technique to achieve the restoration. In order to represent input shapes in a matrix form, vectorization of each aligned sample is carried out by stacking coordinates of dense corresponding points that are generated by a surface matching scheme using non-rigid deformation. An experiment using 3D scans of facial sculptures from Bayon is conducted, and the result verifies the feasibility and effectiveness of our method.
