In the field of mixed reality, virtualization of real outdoor scenes is widely investigated for a number of applications such as telepresence and walk-through systems. An omnidirectional multi-camera system is more useful for virtualizing outdoor scenes than a single camera system, because the multi-camera system can easily capture high-resolution omnidirectional images. However, the exact calibration of the system is necessary to virtualize the real world accurately. In this paper, we describe a method for generating a high-resolution panoramic movie by calibrating an omnidirectional multicamera system geometrically and photometrically. In experiments, a spherical panoramic video has been successfully computed to show the validity of the proposed calibration method. Finally, we show a prototype of telepresence system using an immersive display.
