摘　　要：3维激光扫描技术在大遗址数字化应用中涉及数据采集、数据加工、3维建模等关键技术。以三星堆遗址一号祭祀坑为例,采用Riegl LMS-Z420i3维激光扫描仪和尼康D100数码相机分别获取几何点云数据与纹理数据,并通过PolyWorks软件实现多站点点云数据配准与3维建模,给出大遗址数字化的整个工艺流程。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.
