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.

选用有代表性的贵州少数民族文物―布依族酒壶、水壶以及木制傩戏面具作为研究对象，采用Hiscanner激光扫描测头对其进行数据采集，扫描得到的点云数据可刻录到光盘上作为文物数据永久保存；更进一步地，采用目前流行的逆向工程软件Geomagic studio对点云数据进行数据精简、数据滤波、数据修补、提取特征线等处理后得到NURBS曲面；为保证曲面模型重建的精度，在曲面重建模型后对其误差评价，通过控制误差的方式指导曲面模型重建，使重建的文物曲面模型能真实完整地反映原状；最后，在功能强大的三维造型软件Solidworks中导人重构的NURBS曲面进行曲面缝合、放样等，将其生成实体CAD模型，并对模型的局部特征进行适当的再设计以实现文物实体模型的优化。

Means the parent directory, so this command means to execute "toolchain.sh," which is in the current directory.

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。

Yes,In fact,I'm on our city ream.
