Abstract: In this paper, the women’s convex belly is taken as research subject. An approach combining the measured pressure values on the designated points when one wears the model-body underpants, considering the satisfaction for the body comfort, which applies NURBS deformation algorithm to realizing the personalized digital correction for the convex belly is proposed. Hamming distance is utilized to compare the corrected belly curve with the standard one, and then the most optimal corrected one would be selected. Experimental results show that this digital correction method can reproduce the correctional curve about convex belly putting on the model-body underpants more accurately and truthfully on the condition of guaranteeing the person’s comfort, which attains a comfortable as well as beautiful effect, and thus provides an important reference for the customers’ decisions in the course of virtual shopping.

Key words: convex belly, comfort, Non-Uniform Rational B-Splines（NURBS）, shape digital correction

摘要： 以女性凸肚体为研究对象，在保证人体穿着舒适度的前提下，采用NURBS曲线变形算法对腹部体型进行个性化数字修正。将修正后曲线用Hausdorff距离的误差评判方法与标准人体曲线对比，选出最优的束裤修正曲线。研究表明，该方法不仅能满足人体穿着舒适度，而且能更准确真实地再现凸肚体试穿束裤后的体型修正曲线，达到既舒适又美观的效果，从而为虚拟试衣决策提供重要的参考依据。
