基于轮廓曲线拟合的人体下肢分割及其测量技术

Segmentation and Measurement of Lower Limbs Based on Curve Fitting of Profile

针对当前人体分割方法适应人群窄和尺寸测量不准确的缺点,提出基于轮廓曲线拟合的人体下肢分割及其测量方法。对人体臀部轮廓进行迭代曲线拟合圆以提取臀部特征,根据腿间分叉点实施下肢分割,依照国家人体尺寸标准对下肢10多个关键尺寸进行测量。实验结果表明,该分割和测量方法能增强实验对象的普适性,提高尺寸测量的准确率。

In view of the shortcomings that the current segmentation of body is less adapt to the crowd and the measurement of body sizes is imprecise,the segmentation method of lower limbs is proposed based on curve fitting of the profile.Firstly,the characteristics extraction of body hip are through iterating curve fitting about hip circle and the segmentation of lower limbs depends on the bifurcation point between legs.Then more than ten sizes of lower limbs are extracted according to the national standards of body sizes.The experimental results show that the method enhances the universality of the subjects and the accuracy of measurement.
