| Summary: | Enormous amounts of money and other resources are poured into professional soccer today. Teams will do anything to get a competitive advantage, including investing heavily in new technology for player development and analysis. In this thesis, we investigate and implement an instant analytical system that captures sports notational data and combines it with high-quality virtual view video from the Bagadus system, removing the manual labor of traditional video analysis. We present a multi-platform mobile application and a playback system, which together act as a state-of-the-art analytical tool providing soccer experts with the means of capturing annotations and immediately play back zoomable and pannable video on stadium big screens, computers and mobile devices. By controlling remote playback and drawing on video through the app, sports professionals can provide instant, video-backed analysis of interesting situations on the pitch to players, analysts or even spectators. We investigate how to best design, implement and combine these components into a Instant Replay Analytical Subsystem for the Bagadus project to create an automated way of viewing and controlling video based on annotations. We describe how the system is optimized in terms of performance, to achieve real-time video control and drawing; scalability, by minimizing network data and memory usage; and usability, through a user tested interface optimized for accuracy and speed for notational data capture, as well as user customization based on roles and easy filtering of annotations. The system has been tested and adapted through real life scenarios at Alfheim Stadium for Tromsø Idrettslag (TIL) and at Ullevaal Stadion for the Norway national football team. |
