Performance analysis in invasion games like soccer, basketball, handball, rugby and field hockey requires objective recording and examination of behavioural events of one or more players during training or competition. The primary goal of performance analysis is to provide information to coaches and players about player and/or team performance in order to plan subsequent practices to improve performance or to support preparation for the next match. Performance analysis is most often used to create a permanent record of actions of players within a match through hand-based or computerized systems, often using video technology. Sophisticated data sets offer opportunities for analysing spatio-temporal patterns and network structures. However, these analyses have certain limitations, especially from a tactical point of view. For example, spatial information of the actions of players, if present at all, lacks accuracy and, due to a single camera viewpoint, only on-the-ball actions of individual players are monitored systematically.
