青年女体三维扫描数据的特征围度计算方法
|
摘要
为检验通过人体特征部位宽度和厚度的关系预测其围度数值的可行性,以330名20~26岁的青年女体作为样本进行研究。基于三维人体扫描数据,用Imageware软件获取胸围、下胸围、腰围、腹围和臀围5个人体特征围度部位的水平截面,测量水平截面的宽度、厚度并计算其比值;引入特征系数将特征部位分成6类,并分类对特征围度与其宽度、厚度进行相关分析来验证进行二元线性回归方程设计的可行性;逐类建立特征围度的回归方程并进行验证分析。结果显示,该方法预测的围度值与三维扫描测量的数值误差在±2 cm以内,平均误差在±0.7 cm以内。
In order to test the feasibility of predicting the circumference of the body by the width and thickness of the body's characteristic position,330 young women aged 20 to 26 years old were taken as samples for study. Based on 3-D body scanning data,the horizontal section of chest circumference and lower chest circumference,waist circumference,abdominal circumference and hip circumference of five body feature parts were obtained by Imageware software. The width and thickness of the horizontal section were measured and the ratio was calculated. Characteristic coefficient was introuced to divide the characteristic parts into six categories,and the correlation analysis on the characteristics of girth and its width and thickness was done to verify the feasibility of the two linear regression equation design.Regression equation of characteristics of girth was established and validated by categories. Test results show that measurements predicted by the method has an error of ± 2 cm with numbers measured by 3-D scanning measuring and the average error is within 0. 7 cm.
