Abstract

Motion capture systems provide an efficient and interactive solution for extracting information related to a human skeleton, which is often exploited to animate virtual characters. When the character can- not be assimilated to an anthropometric shape, the task to map mo- tion capture data onto the armature to be animated could be extremely challenging. This paper presents a novel methodology for the automatic mapping of a human skeleton onto virtual character armatures. By ex- tending the concept of graph similarity, joints and bones of the tracked human skeleton are mapped onto an arbitrary shaped armature. A pro- totype implementation has been developed by using the Microsoft Kinect as body tracking device. Preliminary results show that the proposed so- lution can already be used to animate truly different characters such as a Pixar-like lamp, a fish or a dog.
