矢状面曲线形态是研究人体纵截面体型的前提和基础,也是提高服装合体性的关键。基于青年女性三维人体测量,利用逆向工程技术采集点云数据,并抽取表面轮廓曲线。用最小二乘法对采集到的数据进行拟合,得到青年女性正矢状面、过胸高点矢状面、过后背最凸点矢状面、过肩端点矢状面轮廓曲线的多项式插值拟合方程,曲线拟合优度R2达到0.96以上。为进一步量化分析矢状面曲线形态,研究人体纵截面体型和进行体型分类奠定基础。
Sagittal plane curve shape is the premise and foundation of studying longitudinal section shape of human body, and also a key for garment fitness. In this paper, based on 3D human body measurement of young women, cloud data were collected by reverse engineering technology, and the surface contour curve was extracted. Least square method was used to fit the data collected, and gain polynomial interpolation fitting equations of profile curve of the middle sagittal plane, the sagittal plane across bust point, the sagittal plane across the back and the sagittal plane across shoulder point. The goodness of curve fitting R2 is above 0. 96. It lays a foundation for further quantitative analysis of sagittal curve form, studying the longitudinal section shape of human body and classifying the body type.
