Research On The Beauty Of Young Women’s Breasts Based On Reverse Engineering Technology

This thesis explored breast beauty based on two kinds of research methods of objective measurement and subjective evaluation, with150young women in Shanghai aged20to25as the research object, and eventually built the quantitative index of breast beauty and a chest model of75B.This thesis firstly randomly chose150young women aged20to25in Shanghai, the breast data was analyzed through3D scanning and Martin measurement and Polyworks. There were45partial figure characteristics related to the breast. By applying the statistic software SPSS, eight factors were extracted as height indexes, widen indexes, girth indexes, depth indexes, volume indexes, position indexes, chubbiness, gathering to describe the beauty breast. With the ratio of breast height to height (reflecting the relationship between the location of the breast), and the ratio of BP point spacing to shoulder width (reflecting the breast gathering degree), and the ratio of breast depth to bust depth,(reflecting the breast chubbiness level), the breast morphology was divided into27categories.Based on investigation and analysis of a total of250questionnaires that were got in Shanghai, main conclusions had obtained:More than half of women were dissatisfied with their breast shape.Through10experts and7promotion specialist and56common consumer visit, and practice experience, fitting on experience, and so on, the paper got the information about describing the beauty breast, mainly including that the body is symmetry; the comparison between bust-waist is V type; the size of breast is appropriate, the shape of breast is rounded and chubbiness, not flagging. The two side of breast are symmetrical; the position of breast is in the central of the upper part.The thesis got3times subjective breast evaluation through96underwear relevant person, choosing28samples of beautiful breast. From the quantitative point, the breast data was analyzed based on width, thickness and circumference, height, volume data. The young women’s beauty breasts have same characteristic:the ratio of bust height to whole body height was0.71; the ratio of bust width to shoulder width is0.69, breast depth is2.5cm; he FNP to BP point distance is 20cm and the BP spacing is18.7cm; the triangle (FNP to BP to BP)are isosceles triangle, the top angle less than60°and close to equilateral triangle; and there are some other data quantitative standard about width, thickness ratio.After the subjective evaluation, the six75B breast model was divided into34layers; every layer was divided into30points. The data was structured and disposed of average and symmetrical finally established a3D modeling by Polyworks. And then a test was taken to check the modeling is beautiful or not. The result shown that, after the subjective evaluation and average processing reconstruction, the modeling was more suitable to the public aesthetics, the beautiful degree greatly improved.
