论文摘要
给定足球比赛的单眼视频,本文提出了一个计算模型,以估算任何给定时间最可行的通行证。该方法利用进攻球员的方向(加上他们的位置)和对手的空间配置来计算同一团队球员中通过事件的可行性。定向数据是从适当投影到2D游戏字段的身体姿势估计中收集的;此外,通过定义可行性度量,提供了几何解决方案,以确定哪些参与者相互倾向于彼此。一旦分析了6000多个通过事件,结果表明,通过将方向包括作为可行性度量,可以构建强大的计算模型,达到0.7 TOP-3的准确性超过0.7。最后,研究了方向可行性措施与最近引入的预期拥有价值度量标准的组合;获得了有希望的结果,因此表明可以通过将方向作为关键特征来完善现有模型。这些模型可以帮助教练和分析师对游戏有更好的了解并改善玩家的决策过程。
Given a monocular video of a soccer match, this paper presents a computational model to estimate the most feasible pass at any given time. The method leverages offensive player's orientation (plus their location) and opponents' spatial configuration to compute the feasibility of pass events within players of the same team. Orientation data is gathered from body pose estimations that are properly projected onto the 2D game field; moreover, a geometrical solution is provided, through the definition of a feasibility measure, to determine which players are better oriented towards each other. Once analyzed more than 6000 pass events, results show that, by including orientation as a feasibility measure, a robust computational model can be built, reaching more than 0.7 Top-3 accuracy. Finally, the combination of the orientation feasibility measure with the recently introduced Expected Possession Value metric is studied; promising results are obtained, thus showing that existing models can be refined by using orientation as a key feature. These models could help both coaches and analysts to have a better understanding of the game and to improve the players' decision-making process.
