胸围截面轮廓点获取方法优化

Optimization of the Bust Section Contour Point Acquisition Method

为更好地表达胸立体尺寸,建立胸围通用测量法与轮廓点依次测量法的转换模型,以胸围截面轮廓点的获取方法为主要研究对象,分别采用"胸围轮廓点一次测量法"和"胸围轮廓点依次测量法"获取胸围尺寸数据,通过Excel软件分析两种方法的测量精确度、稳定性和实际可操作性;通过SPSS软件分析两组数据间的差异性和相关性,建立转换模型,并对模型进行验证。结果显示:(1)方法 2得到的数据组离散程度较小,较方法 1稳定,但实际可操作性弱于方法 1;(2)方法 1和方法 2得到的数据组间具有显著相关性且存在极显著差异;(3)对方法 1和方法 2建立回归模型,经验证确定最优回归模型为y=-91. 424+3. 101x-0. 012x^2。

In order to better express the chest 3D size,this paper established the conversion model between bust universal measurement method and the contour point of the measurement method.The method of obtaining the outline of the bust section was taken as the main research object.The bust size data were obtained by two measurement methods:"bust contour point measurement"and"bust contour point measurement method".The accuracy,stability and practical operabi-lity of the two methods were analyzed by Excel software.The variability and correlation between the two sets of data were analyzed by SPSS software.And the conversion model was established and validated.The results showed that:①the data group obtained by the method 2 had a small dispersion and the data was more stable than the method 1.But its actual operability was weaker than the method 1.②There was a significant correlation between the data sets obtained by methods 1 and 2.And the difference was significantly obvious.③The regression model was established for the method 1 and method 2,and the optimal regression model was y=-91.424+3.101x-0.012x^2.
