A vision framework for the localization of soccer players and ball on the pitch using Handycams

The current performance requirements in soccer make imperative the use of new technologies for game observation and analysis, such that detailed information about the teams’ actions is provided. This paper summarizes a framework to collect the soccer players and ball positions using one or more Full HD Handycams, placed no more than 20cm apart in the stands, as well as how this framework connects to the FootData project. The system was based on four main modules: the detection and delimitation of the soccer pitch, the ball and the players detection and assignment to their teams, the tracking of players and ball and finally the computation of their localization (in meters) in the pitch.
