Reconstruction of the stone tablet Based on Vectorization of Images

摘要

Traditionally, it costs a lot of time and efforts to reconstruct the stone tablet manually. The system which can transformat the image got by photography into the dxf file is proposed and make it possible to program automatically and to machine in numerical control machining. To get the dxf file, using the image preprocessing、 the surrounding eight pixels and the least square method to complete the Vectorization in this paper. Finally, the specific interface program to generate a DXF file is given. The result proved feasible and the comparison of the source image and the objective dxf file opened by AutoCAD is given in this paper.
