Large-scale Virtualized Reality

In this paper, we present our project for realizing Virtualized Reality in a large-scale space such as a soccer stadium, concert hall, etc. . We have developed an extended system of CMU 3D room [3] in an efficient way so that 4D digitization of a large-scale space can practically realized. We place 16 progressive scan cameras around a large space (e.g. 70m 50m with 25m height). The videos from those cameras are digitized into PCs that are connected via Ethernet. A camera calibration technique for a large-scale space that is accurate enough to apply CV-based algorithms is developed. We also present a method to omit the calibration process with an idea of “Projective Grid Space”. The recent results and future works are presented for demonstrating the significance of the project as a CV-based practical application.
