Design and implementation of a virtual-real interaction system

Abstract

We design and implement a virtual-real interaction system using the optical motion capture device. First, we construct immersive interaction environment, such as setting OptiTrack parameter, calibrating cameras and transferring data, which play an important role in building environment. Second, we research virtual-real interaction technology based on optical motion capture device. And we acquire the motion data of human and rigid body, transferring them to the virtual scene. So we can accurately rotate and translate the corresponding virtual objects in real time. Finally, we design and implement natural immersive virtual-real interaction system. The experiment result shows that our system can preferably implement virtual-real interaction such as human and rigid body with markers, human and virtual objects.
