The representative minority cultural relic-pottery relic of Buyi minority and the two wooden masks is taken as the research object. Firstly, Hiscanner laser scan detector was adapted for data collection, and then obtain point cloud data which could be recorded on disc for permanent saving was obtianed; Furthermore, the new popular reverse engineering software Geomagic for some disposals of point cloud data was adopted in data condensing, data mending, data filtering, feature line picking up to obtain NURBS surfaces; and then the error between the reconstructed CAD model and the point cloud data was evaluated to guarantee the precision of surface reconstruction to keep the relics keep its original appearance. In the end, the NURBS surfaces are imported to 3D software Solidworks and entities of CAD are generated by surface sewing, mold loft and ablating and other instructions.
