| Abstract: | Large historic building relic commonly has complex construction,and the digitization protection is a cockamamie and heavy workload.To resolve this problem,we present a 3D digitization method with multi-precision measurement data fusion.we use GPS to observe precise control network and locate the coordinate and orientation about the historic building relic,employ 3D laser scanner to acquire dense point cloud and build precise 3D model,and use high accuracy non-prism electronic total station to observe precise characteristic points and detect precision with 3D laser scanner for each other.The paper takes the digitization protection of Great White House Temple’s Qiyun Pagoda for example,has a detailed presentation on method and technology in field work,and discusses the method and technology in interior work in several aspects,such as point cloud registering,3D modeling and data analysis. |
