Panoramic Movie-Rendering Method with Superimposed Computer Graphics for Immersive Walk-Through System

Abstract

This paper describes a technique for developing an immersive walk-through system that implements a rendering method for superimposing computer graphics onto a panoramic movie in an immersive walk-through system. The system is composed of a locomotion interface and an immersive spherical display. In this study, we analyze the camera path from the movie to stabilize the orientation of the camera for rendering an immersive image. Further, the system superimposes computer graphics (CG) onto the image according to the system coordinates from the movie. We implemented the proposed rendering method to realize a free viewpoint image with the movie and the CG by moving the viewpoint.
