The 3D laser scan technology is applied in the digital model of great historic site

which is involved with data acquisition

data post processing

rebuilding 3D model

etc. In this paper

we used that the first fete pit of San Xingdui ruins as an example

which used Riegl LMS Z420i 3D laser scanner and Nikon D100 digital camera to obtain geometry point clouds and texture separately. And then

we accomplished that the registering multiple laser scans and accurate 3D model by the soft ware of PolyWorks. In conclusion

we could present the whole process flow in the digital model of great historic site.
