Based on 3D virtual fitting technology, this paper simulates and reproduces the fabric patterns and sewing processes of 12 characters’ costumes in different scenes on the basis of completing the archaeology of the characters’ costumes in the painting, so as to realize the 3D virtual sewing and digital simulation restoration of the characters costumes. This paper draws the style diagram, structure diagram and 3D virtual simulation diagram of the character costumes in the painting. The article further improves the research on the costumes of the Five Dynasties and Ten Kingdoms, which has a certain reference value for the study of ancient character costumes and the promotion of Chinese garment culture. At the same time, it provides a reference for the design of artistic works such as character costumes in film and television and games.
