Large number of archaeological fragments are mixed up when they are excavated, which brings difficulties for their reassembly. Computer aided restoration technologies have developed greatly in recent years, and approaches nowadays assist experts in a large scale. However, there still exist large number of fragments which are not reassembled and repaired. The current approaches have some disadvantages which affect the reassembly in large scale. This is because of the particular characteristics of archaeological fragments which affect the effectiveness of the current approaches. On the one hand, the archaeological fragments are piled up when they are excavated in archaeological sites. On the other hand, the fragments are changed during the long time because of abrasion and erosion. Therefore, innovative methods for the classification and reassembly of archaeological fragments are needed urgently. In this paper, the relate work on the classification and reassembly of archaeological fragments are first presented. Then, the problems when applying current approaches are summarized. At last, a feasible plan is given in order to classify and reassemble the fragments efficiently. By intact surface segmentation and partial matching with a complete model using discriminative feature descriptors, large number of fragments can be positioned with respect to a template model. The matching results provide the classification information and can assist the reassembly of fragments.
