Cloth X-Ray: MoCap of People Wearing Textiles

摘要

The contribution presents an approach for motion capturing (MoCap) of dressed people. A cloth draping method is embedded in a silhouette based MoCap system and an error functional is formalized to minimize image errors with respect to silhouettes, pose and kinematic chain parameters, the cloth draping components and external wind forces. We report on various experiments with two types of clothes, namely a skirt and a pair of shorts. Finally we compare the angles of the MoCap system with results from a commercially available marker based tracking system. The experiments show, that we are basically within the error range of marker based tracking systems, though body parts are occluded with cloth.
