少数の計測寸法から作成した個人別有限要素手モデルを用いたMoCapデータに基づく接触解析

抄録

We proposed a method to create an individual finite element (FE) model and to conduct contact analysis between an object and the model based on measured motion. There are 3 steps to create the model. First, we estimate full set dimensions to deform a template polygon model from a small number of measured dimensions. Second, to create an individual polygon hand model, we deform a template model based on the full set dimensions. Third, an individual FE hand model is created by transferring nodes of a template FE hand model based on deformation of vertices in second step. To conduct contact analysis based on measured motion, we calculate joint rotation angles from a motion capture(MoCap) data and rotate each link attached to bones. We compared contact regions by real hands and created model for evaluating accuracy of the created model. Results showed that the real hands and the created model have almost same shape and we can conduct contact analysis with proposed method.
