Live mixed-reality 3D video in soccer stadium

Abstract

This paper proposes a method to realize a 3D video display system that can capture video from multiple cameras, reconstruct 3D models and transmit 3D video data in real time. We represent a target object with a simplified 3D model consisting of a single plane and a 2D texture extracted from multiple cameras. This 3D model is simple enough to be transmitted via a network. We have developed a prototype system that can capture multiple videos, reconstruct 3D models, transmit the models via a network, and display 3D video in real time. A 3D video of a typical soccer scene that includes a dozen players was processed at 26 frames per second.
