Abstract
This study proposed a method to construct an anatomy-based variational modeling of a Digital Hand model, which can be used to efficiently generate various individual hand models with different dimensions for virtual ergonomic assessments. The skin surface of a generic hand model was hierarchically partitioned into 15 segments according to the hand surface anatomy. Then it was deformed by scaling and aligning the segments so that it satisfied individual hand dimensions. Moreover, the hand models of different hand postures with markers were reconstructed using a multi-view 3D model reconstruction technique. The extracted positions of markers were used to estimate the individual bone-link structure. The proposed method was validated through comparing the generated hand skin model which fitted the hand dimensions of a subject with his MRI-measured hand surface, and comparing the generated bone-link structure, which fitted joint motion of the subject, with the reconstructed hand models based on a multi-view 3D reconstruction technique.
