Inner Structure Estimation of Human Body Model for Simulation of Interaction with Clothing

Abstract

A human body model for clothing simulation should reflect inner mechanical characteristics, because shape of clothing is defined by mechanical interactions between clothing and human body. A technique that estimates unknown inner structure of human body is proposed, as it is not easy to measure inner structure of each person. Isomorphic mesh that we proposed was utilized to have one-to-one correspondence between points on different human body surfaces. Mesh structure of isomorphic mesh is identical for any human body surface, and any point on a human body surface can be corresponded to a point on another human body surface. Unknown inner structure of a human body was estimated by deforming mass-spring model of human body according to correspondence of surface shapes. From the results, possibility of the estimation was suggested. Improvement of accuracy of the estimation is expected by setting of proper parameters of the mass-spring model with results of measurement of inner structures of human bodies.
