A Study On The Women's Body Shapes For Clothes Fit

This paper studies the variations of human body shape and establishes the model of relationship between body measurements, which facilitates sizing survey for body measurements and provides theoretical foundation for the 3-D body simulation by inputting 2-D sizes in computer. Furthermore, non-contact measurement, a new method of human body measuring, is studied in this paper.Based on the database of human body shapes measured with Wacol contact measuring equipment, the mathematical model of human body is developed by the use of regression analysis.The mathematical model of human body can well predict the 41 variables in the 62 measurements, with the coefficient between prediction value and original one reaching more than 0.75. In the study of human body shape, the 41variables can be used to predicate such basic dimensions as height, breast and waist, which greatly facilitate the process of body measurement survey. In the construction of 3-D garments, the key dimensions of garment panels can be predicated from this mathematical model except for the measurements of shoulder width and upper crotch.The control dimensions can be derived from key dimensions. With the translation from 2-D sizes to 3-D coordination, the 3-D simulation of human body is realized by inputting 2-D sizes.To explore the new equipment for non-contact measurement, Fourier transform profilometry is introduced into body measurement. With the non-phase-shifting of 2-D Fourier transform profilometry measurement and grid projection system, combined with digital weight filtration and the algorithm of phase unwrapping based on ranking of reliability, the data of three dimensional body proliferation is measured. The recovery of body surface was studied with the methods of phase unwrapping and development. The setting of 3-D coordination and link of body surface were theoretically discussed, which was a historic step towards the non-contact bodymeasurement system. Suitable for body measurement, the method of Fourier transform profilometry is convenient, fast and with low requirement for testing equipment.With the large sizing survey by contact measurement system, this paper studies principles of women's body shape in terms of geographic region, age group and 3-D bra construction. The results have been applied to the clothing industry, especially for the manufacture of standard dress form conforming to Chinese women's body shape in the underwear sectors.
