Abstract: Abstract: How to use digital means to reconstruct cultural relic fragments is an important issue, which is focused on by current archaeologists and historians. 3D laser scanner is used to collect the pieces data of bronze ware pottery mould in this study. Noise points are removed by the human-computer interaction. The surface of point clouds is created using the theory of implicit surface. The point cloud data conversion is realized using the method of adjacent points. The holes on the surface are repaired by interpolation. The shape, ornamentation, structure is adjusted using the software of reverse engineering and 3D modeling. The bronze pieces are created using the method of reversed normal on the pottery mould. Bronze pieces are arranged evenly along the axis which has been got from guides. Then the crack of the complete bronze is repaired. The texture of bronze ware is repaired according to photos and literatures. Finally the real bronze ware is created after the 3D printing software repairing the fragments which is created on the process of format conversion. The shape of created bronze is intact, the ornamentation is beautiful. In a word, the created bronze ware fully meets the requirements of design.
