Custom design of cheongsam based on digital 3-D human model

This reported research worked on the problems of poor fitting and long design and pattern making cycle in the traditional pattern generation process for custom-made body-fitting garment. A method of custom-design of cheongsam based on a three-dimensional visualization technology and reverse engineering technology was adopted. The 3-D virtual design platform was used for the parameterization setting of the human body model supported by the 3-D scanned data of 23 characteristic parts of the human body. Then, a characteristic human body model of "body-fitting tolerance" was constructed by adding the tolerance of the four key parts of the human body model, and the 3-D cheongsam style and internal segmentation design were carried out on it. Finally, the 3-D cheongsam surface was automatically flattened to obtain the 2-D pattern, and the garment made of the 2-D pattern is subjectively evaluated. The results show that the subjective evaluation index of the garment reached more than 4.0 points, and this method can be used to carry out effectively the design of body-fitting garment and the automatic generation of pattern. © 2021, Periodical Agency of Journal of Textile Research.
