Abstract

In order to enrich the sports TV programs, there are various requests to obtain the useful information during the game for on-air graphics. Especially, for any ball game, time series 3D positional data of the ball is the one of the most important information. We developed a new on-air 3D graphics system for live sports broadcasting, it is equipped with object tracking function, to track a volleyball. The positional data of the ball is calculated in real-time, both from video analysis of PTZ cameras for broadcasting, and from PTZ sensor data. Our experiment shows that the system can produce accurate 3D ball compositing in real-time for on-air graphics.
