Reproduction of Motion for Immersive Mixed Environments

摘要

A sense of presence is one of the important virtual experiences. Over the past few years a considerable number of studies have been made on how to immerse in a virtual space. In this paper, we propose an immersive mixed environment system that has users experience the advanced immersion with motion information. The application of proposed system takes up the image sequence which people cross a suspension bridge. We reproduce the motion of the suspension bridge by means of walking, wind and so on. The image sequence is the omnidirectional images recorded by an omnidirectional vision sensor. To detect the motion information from omnidirectional images, optical flow is used. The motion-base system is moved by the motion information detected by optical flow, and the image sequence is projected on four huge screens (front, right, left, and bottom). The system can reproduce the real motion of the bridge with the motion and the image.
