Body Size Classification Of Young Women Based On The Difference Between Front And Back Of Body

With the development of society, people’s clothing aesthetic consciousness also will continue to improve, people on their own body and dress comfort, aesthetics also have higher requirements. At present, China’s garment enterprises by implementing the clothing sizes is mainly according to the formulated by the state GB/T1335.2- 2008GB/T133 garment size designation for to production and costume design, the main basis of chest and waist the dimensions of difference to divide the size. This only consider the thoracolumbar overall dimensions data of somatotype method and real body shape is contrary. Body shape is the body’s fat, thin, tall, short and surface curve of the comprehensive embodiment, shape differences not only reflected in the size difference in overall dimensions of human thoracolumbar and even clothing sizes for the same two people, also can contain different body. Before and after the specific form is inconsistent with the complexity of the structure of the human body, waist hip transverse section before and after the morphological differences also exist. Classification is an important foundation of clothing structure, which is directly related to the fit and comfort of the garment.This paper aims to analyze the cross-sectional shape of human body by observing the cross-section of human bust waist hips stroke were divided into two parts, and on this basis, the human body is divided into front and back, in the shape of the nations existing classification criteria, combined with cross-sectional differences before and after the classification will further subdivide GB and make classification more accord with the real body shape, expanding the coverage of somatotyping, improve the accuracy of classification and accuracy, to establish a more scientific and detailed classification standard sizes, for garment enterprises to provide more scientific and standard specification, design more in line with the clothing structure and the version of the human body, and ultimately improve the clothes fit and beautiful, promote innovation and the development of garment industry.This paper selects 121 age in 18- 26 years old female college students as the experimental object, using non-contact 3D body scanner acquisition of human body dimension data and cross-sectional images, extraction sample most reflect the size characteristics of the chest, waist, hips cross-section and the size of the data, through the observation analysis shape of the cross section of the cross section curve is divided into before and after the two parts and calculate waist hip before and after peri degree size data. According to the correlation analysis to establish the chest before and after confining effect on the size of the different degree of maximum to determine the cross-sectional shape divided according to the relationship between the before and after the bust size. Finally in national standard based on combined with cross-sectional shape, of GB were further subdivided. Through mathematical analysis, the average cross section of each size of the point, and even points into the line, and finally get the average of the chest, waist, hip cross section shape. And then the body classification standard to establish "China body classification + before and after standard cross section difference type classification standard. Finally, summarize and analyze the characteristics of the various body and the characteristics of the various body, in the perspective of the female aesthetic, the use of the principle of visual illusion to the various size of the corresponding clothing design and research and conduct a series of clothing design practice.The research innovation of this subject is mainly reflected in 3 aspects:(1) the human body is divided into two parts before and after, in China’s current shape classification standard for further subdivision done: according to the difference of human thoracic and lumbar hip transverse section before and after the trunk of the human body is divided into before and after the two parts, on the basis of China’s current shape classification standard, according to the shape of human thoracic and lumbar hip cross-sectional differences before and after further refinement, make the body more in line with the real human body, fit the human body tends to diversification, personalization trend, somatotype coverage available to more people, to enhance the universality and accuracy(2) to establish China current shape classification and cross section of the body types of standards, to the clothing enterprises in the future to provide more scientific clothing size standard, enable mass production of garment structure is more fit for human, making garment enterprises subdivided shapes in a classification standard production line in accordance with the classification of body shape of clothing samples, for the clothing structure design provides more scientific reference basis, thus producing a fit with the type of garment, enhance the clothes fit and comfort.To grasp the basis of research and design(3) on the cross section and shape of the in-depth study for the clothing designer provides a new perspective to the clothing structure design has the important guiding significance, the subject of the cross section of the curve shape, make designers more in-depth knowledge and understanding of the human body, the body and the clothing modelling, the shape of the designers in the fashion design, and from the human point of view, we improved apparel and clothing technology, make the clothing to meet the practical function and closely combined with human body structure characteristics, the cover body defects, prominent human advantages, make human body beauty best show.
