Location-Aware System Based on a Dynamic 3D Model to Help in Live Broadcasting of Sport Events

摘要

Broadcasting sport events in live is a challenging task because obtaining the best views requires taking into account many dynamic factors, such as: the location and movement of interesting objects, all the views provided by cameras in the scenario (some of them wireless, mobile, or attached to moving objects), possible occlusions, etc. Therefore, a technical director needs to manage a great amount of continuously changing information to quickly select the camera whose view should be broadcasted. In this paper, we present a location-aware system that helps technical directors in the broadcasting task, using a 3D model updated continuously with real-time location data retrieved from the scenario. They can indicate in run-time their interest in certain moving objects and the system is in charge of selecting the cameras that provide the kind of views required.
