Three-dimensional modeling, repairing and visualizing method and device for underground historical remains

The invention discloses a three-dimensional modeling, repairing and visualizing method and device for underground historical remains, and the method comprises the steps: completing the information collection of the appearance shape, color size and material structure of the underground historical remains through a depth-of-field camera and a surveying and mapping tool, and completing the scanning and screening of pictures and surveying and mapping data on a computer; forming a unified format of a total metadata reference standard and information; according to the collected data information of the historical remains, using Revit software of a BIM system to construct related family modules and construct a three-dimensional visualization model of the historical remains, using Lumion to carry out repairing and rendering based on the three-dimensional model to obtain a simulated three-dimensional model, and achieving horizontal three-dimensional display of the simulated model through a single-channel three-dimensio
