Archaeological and digital restoration of straight-front robe of Mawangdui Han Dynasty Tomb based on 3D reverse engineering and man-machine interactive technologies

Abstract

Based on 3D reverse engineering and man-machine interactive technologies, this paper completed the pattern development of a straight-front robe of the Mawangdui Han Dynasty tomb and restored the straight-front robe by virtual simulation technology. Firstly, the garment contour was extracted from the straight-front robe image of the Mawangdui Han Dynasty tomb, and then the garment model was established in the 3D virtual environment. According to the style characteristics of the straight-front robe, the structural curves were drawn on the adjusted 3D robe surface, and the different curved surfaces formed by these curves were expanded to obtain 2D garment patterns. Finally, the unfolded patterns were stitched on the virtual human body to realize the digital restoration of the straight-front robe of the Mawangdui Han Dynasty tomb. Compared with the current methods of garment restoration, the method proposed in this paper not only reduces the technical requirements of pattern-making for archaeologists but also for unearthed cultural relic garments, the final pattern can be obtained without consulting a lot of data and repetitive modification of pattern, to improve efficiency and save manpower. Our proposed technology provides a new practical method for costume archaeology and restoration.
