Automation of Human Body Model Data Measurement Using Kinect in Motion Capture System

A motion capture system requires a collection of human body model data which reflect body features of a user. The existing motion capture systems utilize human body model data with fixed body proportions; or require manual input of human body model data, which is unwieldy. This paper proposes how to measure the length of body joints using the Kinect's depth sensor, and how to put the measured value into a motion capture system automatically. Experiments during the study have shown that human body model data drawn out from the method proposed in this paper is almost matching to actual body length.
