Abstract: It's a great requirement for Historic Preservation Architecture to be digital preserved.Traditional virtual reality technology acquisition cycle is long, workload is heavy, and it's inconvenient to showcase the result.Combined with the characteristics of the historic preservation architecture, we research 3D panoramic image reproduction method based on real photos.Put its historical trajectory data, key parts and engineering data into the digital view by hotpot interaction.It becomes a digital archive of Historic Preservation Architecture.Use the package technique, the 3D panoramic image is very convenient to show on the network platform.
