Determination of workspace for motion capture using Kinect

Abstract

This paper describes the method of determining the workspace for shooting motion capture in real time. Sensor Kinect for Windows v1 and v2 were selected for motion capture, Kinect2BVH program for recording data in the format of BioVision Hierarchy and mathematical processor MATLAB for computation and data visualization. In order to identify the zone in which Kinect successfully reconstructs skeleton, we conducted an experiment in which a person moves smoothly in the captured space. Reconstruction errors are defined as sudden unnatural acceleration of movement of the limbs. The result is a distribution map of the skeletal reconstruction accuracy in the area of Kinect v1 vision. Also, calculations were made to determine the limits of angular accelerations bending joints, and as a result more accurate maps were obtained for the capture with Kinect v1 and v2. These developments are used to construct virtual reality scenes.
