Fig. 15: 3D model results.

a Top layer model: this model primarily reflects the five large burial chambers in the tomb, including the east, west, south, north, and central chambers. b Middle layer model: four crossbeams divide the surrounding four side chambers into eight smaller chambers, forming a nine-chamber layout. c Bottom layer model: clearly displays the distribution of artifacts within the burial chamber and their spatial relationships. d Detailed chamber views: shows detailed texture maps of individual sections of the tomb. Labels “e,” “w,” “s,” “n,” and “m” correspond to the east, west, south, north, and central chambers, respectively, with subscripts indicating specific sub-chambers or layers.
