基于自动测体的围度曲线拟合模型

Human body circumference curve fitting model based on automatic measurement

通过拍摄人体正面和侧面的图像,提取其轮廓线形用于服装三维人体尺寸的自动测量技术。该技术成本低,转换后二维尺寸的计算简单快速,适合产品的商业化。(一般的计算方法是对人体围度进行样本分析,利用拟合方法获得不同号型样本的围度曲线函数模型,通过围度曲线的二维信息估计尺寸。)主要基于自动人体测量需要,在选取号型随机样本的试验基础上,使用指数曲线、对数曲线、二次曲线和三次曲线拟合其中胸围曲线,建立对应的围度函数模型并对其在误差和线形方面展开详细的分析与比较,论证这些模型的合理性与不足之处,为建立更适用的围度尺寸函数模型提供参考。

The body contour extracted from the images of front and side body taken by digital camera is used in technology of automatic 3-D body measurement.This technology suits with business because of its low technical cost,simple and fast computing process.（The generic method is to estimate the size by analyzing the circumference of examples and getting the model constrained by the circumference＇s width and thickness which is a function with curve fitting.） This paper discusses the models about the deviation and curve＇s shape.The models are fitted by exponential,logarithm,quadratic polynomial and cubic polynomial functions.The models＇ rationality and disadvantages are demonstrated,providing a reference to make more appropriate models for measuring body circumference.
