One of the common usages of a captured human body motion in automotive application is creating swept volumes of the body surfaces based on the trajectories of its motion. Recent development of depth sensors enables fast and natural motion capture without attaching markers on subjects’ bodies. Microsoft Kinect is one of widely used depth sensors. It can track a whole body motion and output a skeleton model.

A new method is developed to create the swept volumes from the motion captured by Kinect using an open source graphic system. The skeleton motion is recorded in a file format that is flexible to retain the skeleton’s structure and acceptable to various graphic systems. The motion is then bound with a surface manikin model in the graphic system, where the swept volumes are generated. This method is more flexible and portable than utilizing a commercial digital manikin, and potentially provides more accurate result.
