Implementation of Digital Twin Campus by Mixed Virtual Reality Design and Construction Technology

This paper aims to realize digital twin campus by combining hybrid virtual reality technology, three-dimensional laser point cloud technology and BIM technology. First, Trimble TX8 3D scanner is used to collect the data of the target building, and then Trimble RealWorks is used to synthesize, splice, modify and measure the collected point cloud data. Then the synthesized point cloud model is imported into Revit as a reference, and the reverse modeling of point cloud is implemented in Revit, and the corresponding virtual 3D model of Glassroom is constructed. Because of the lack of the original drawings of the building, the second design and analysis of the target building are carried out, and the stability of the redesigned Glassroom structure is analyzed by using SAP2000. Finally, Trimble mixed virtual reality projection is used to make the digital double glass room.
