Firstly, the research sorted out the cultural connotation of the ancient city space from the three spatial levels including space, block and street pattern and then established the geospatial database. Using the key technologies of oblique photogrammetry, laser point cloud, 3D modelling and panoramic technology to restore and visualize the ancient city and then developing the virtual digital display platform which integrated the functions of digital model integration, route recommendation and customization, panoramic roaming and interaction.
