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.

Based on the human torso point cloud, this paper proposes a method from the 3D design of the corset to the 2D pattern expansion. The point cloud of the human body is obtained through 3D scanning. The human body model for research is constructed, and the 3D basic style design of the corset is carried out, based on the same style and different structural line design, and through the curved surface flattening platform to convert 3D into 2D patterns. The verification was made through a virtual simulation platform and physical production methods. This study enriches the application prospect of digital technology in clothing design. Our proposed solution provides a more intuitive wedding dress design method and improves fit and comfort. It can significantly reduce the difficulty of wedding pattern-making and improve the efficiency of wedding design. In addition, our proposed method is not only suitable for wedding dress design, but also other styles of clothing design.

To understand the influence of flat collar, closure collar, and shawl collar on the perceptual impression of women's suits, 12 pairs of adjectives used to describe the collar type of suits were determined by using the method of perceptual engineering and semantic difference. With the help of virtual fitting technology, 22 kinds of suit simulation pictures were drawn. Through the questionnaire survey, this paper studied the perceptual evaluation of different collar types of women's suits and then used the mean statistics and corresponding factor analysis to process the survey data. The results show that 1) the factors of stability, elegance, and style have influenced the collar design of women's suits; 2) different collars brought consumers different emotional feelings, for example, the shawl collar was simple and soft, the flat collar was professional, closure collar was elegant. The results can be used to guide the design of the female suit collar.
