ITAST (Iranian Textile Association of Science and Technology) Journal of Textiles and Polymers 2322-5203 9 1 2021 01 01 Study on Breast Shape Changing in Various Body Positions Using Depth Camera13 Study on Breast Shape Changing in Various Body Positions Using Depth Camera 13 26 126731 EN Journal Article 2021 02 20 In this research, 3D scan based on depth camera<br />is used to measure, and analyze the breast shape changes<br />in various body positions. 3D breast shapes of women are<br />extracted from data obtained from a depth camera. A<br />measurement method is developed based on cross section<br />lines to get the 2D breast pattern. 3D breast shape and 2D<br />breast patterns in five body positions are determined and<br />compared to each other. To calculate the difference, 3D<br />breast form and volume, also area and form of 2D breast<br />pattern are measured. The results show that the breast<br />form and volume in various body positions is not the same.<br />Women have the highest volume and area of breast in the<br />position ‘posture of 45 elbow-bend and arms to the back’<br />subsequent the position ‘posture of 45 elbow-bend and<br />arms to the front’, ‘lower arm beside the body ‘ and ‘raise<br />arm overhead and holding on the brow’, respectively. Also<br />in the position ‘holding arm overhead’ the lowest volume<br />of breast for women is observed. The difference of breast<br />volume in the largest and smallest shape is about 23%. The<br />combination of measuring breast volume and form at the<br />same time can provide effective information for bra cup <br />design. http://www.itast.ir/article_126731_0a36cc7cafe5e68b74fb4303922d75da.pdf
