Design and Implementation of Panoramic Movie System by Using Commodity 3D Graphics Hardware

摘要

In this paper, we introduce a new deign approach of panoramic movie system. The system, named as PanoVi by authors, captures 360-degree surround movie from a view-point by using four wide-angle video cameras, and then the video streams are encoded as a single stream of standard video format. At the viewing side, geometric correction and image mosaicking are performed in real-time by using commodity 3D graphics accelerator hardware equipped with most personal computers. By mapping the mosaic on the inside wall in 3D space, the viewing system renders partial view of arbitrary direction as a virtual environment. This approach is suitable for real-time transmission of panoramic movie because this system uses standard video format in transmission layers. We developed a prototype system based on Windows and DirectX8 environments. We confirmed full-rate interactive panoramic movie playback on commodity Pentium4 based PCs
