本文介绍了ASPOGAMO，一个视觉跟踪系统，确定足球运动员的坐标和轨迹的摄像机视图的基础上，电视广播。为此，ASPOGAMO解决了一个复杂的概率估计问题，该问题由三个子问题组成，这些子问题以微妙的方式相互作用：摄像机方向和缩放因子的估计，玩家路线的跟踪和平滑，以及遮挡后被跟踪玩家的消歧。本文集中在系统方面，使其适合在无约束条件下操作，并在（几乎）实时。我们报告在RoboCup 2006年的公开演示中获得的结果，我们进行了广泛的实验与真实的数据，从现场报道的2006年世界杯在德国的比赛。
This paper describes ASPOGAMO, a visual tracking system that determines the coordinates and trajectories of football players in camera view based on TV broadcasts. To do so, ASPOGAMO solves a complex probabilistic estimation problem that consists of three subproblems that interact in subtle ways: the estimation of the camera direction and zoom factor, the tracking and smoothing of player routes, and the disambiguation of tracked players after occlusions. The paper concentrates on system aspects that make it suitable for operating under unconstrained conditions and in (almost) realtime. We report on results obtained in a public demonstration at RoboCup 2006 where we conducted extensive experiments with real data from live coverage of World Cup 2006 games in Germany.
