A Method To Identify Defensive Assignments In Team-Based Invasion Sports Using Spatiotemporal Trajectories |

---|---|---|
Several works in GIScience propose approaches to identify general motion patterns through the analysis of objects' trajectories. However, they are not suitable to identify functional relationships in scenarios where domain-dependent motion behaviors exist. In this work, we explore the identification of a particular pattern found in team-based invasion sports. We propose a method to identify defensive assignments between players of opposite teams based on the analysis of their trajectories. A defensive assignment happens when a defensive player blocks or hinders the progress of an opponent player inside his/her field. The defensive assignment can be classified as a behavioral pattern because it combines other behavioral patterns, such as pursuit, evasion, attack and defense. The identification of the assignments takes into account the following aspects of the players' trajectories: proximity, position, speed and direction. The assessments pointed out that the method provides promising results, achieving 84% of success rate when compared with the analysis of a human specialist. |
