衣服着装動作シミュレーション

Abstract

In this study, we tried to simulate human bodily movements to put on clothing, and succeeded to simulate the movement. This is a combination of mechanical clothing simulation and measurement of bodily movement.In the clothing simulation, cloth is assumed to be continuous elastic body and mechanically formulated. The equilibrium state of cloth is calculated by minimization of accumulated energy based on the strains and forces determined by deformation of cloth. Though to put on clothing is dynamic movements, the static calculation was iterated in the simulation because the movements here were very slow.A vest was targeted because of its simple structure. A clothing model of a vest was constructed from paper patterns of component parts. The bodily movements to put on clothing were measured by a motion capture system. A virtual human model was moved according to the measured data of the movements.First, shape of a vest in stable state hanging in the air was calculated, human body model was started to move, then the shape of the vest in stable state was calculated in every step of the movements. By the above calculation, the movements to put on clothing were reproduced with the simulation.
