Quantitative analysis of the relationship between the male body shape and block pattern based on the three-dimensional human model

As consumers increasingly demand more diversified and personalized clothing options, personalized customization has become a hot topic in the garment industry. This study aims to analyze the relationship between the male body shape and block pattern by flattening the prototype surface and conducting quantitative analysis. The study established a three-dimensional box prototype wire frame model on a human body model to obtain the prototype’s characteristic size automatically. This enabled the creation of two-dimensional personalized prototypes using surface flattening and the geometric expansion principle. The study also summarized a prototype pattern correction rule by establishing a regression relationship among the human characteristic parameters and the size of the prototype site and the coordinates of the shoulder and back control points. Finally, the correction rule was validated through virtual fitting of a special body model. The result shows that the prototype generated using the flattening method presented in this paper has a high fitness degree and short time consumption and the correction rules can effectively improve the problems of prototype misfit, which can provide an idea and data reference for clothing personalized customization.
