Motion simulation of the hip joint using an optimized markers configuration

Yahia-Cherif, L. and Molet, T. and Magnenat-Thalmann., N.


Abstract: This paper presents a methodology that combines MRI and motion capture systems (Mocap) to simulate and visualize the hip joint motion with an optimized markers configuration. MR images are used to capture the subject’s anatomy as well as the trajectories of the skin markers that are attached to the subject. The anatomical models of the subject are reconstructed and the markers trajectories are computed from the images. The best markers configuration is selected based on the criteria of markers displacements due to skin artifacts. The optimized configuration is used for recording external movements with the Mocap system. The resulting animation is mapped onto the virtual body of the subject including internal bones and the joint motion is visualized.
