摘要：In the developing of 2D non-contact anthropometry and application system, automatic pattern generation of men’s pants system is important component. Based on 3D point-cloud data of human body, this paper probes the calculated formulas of key parts’ width in front and back pieces of pants. First, obtain the total girth and the front/back girth of waist, abdomen, buttocks, thigh, knee and ankle, and set the coefficients to establish the regression equation by using SPSS. Meanwhile, 6 kinds of devised styles are summarized by observing styles of men’s pants, which are divided into landscape orientation, lengthways orientation and slant segmentation all included straight line and curve. After the users enter into automatic pattern generation of men’s pants system, they can choose devised styles in the interface of design, and then related patterns can be automatically generated in the interface of pattern. VS software is used to make programming, ganged style of pants in human body is realized by MATLAB, and so the pattern can be automatically generated according to the rules of pattern and devised styles. This study completes part of the work for the conversion from 3D garment pattern to 2D, to make up that the 2D non-contact body measurement system cannot directly obtain 3D sizes, and provides the basis for automatically pattern generation of pants.
