It allows determining such events in a real-time and semi-automatic context, thanks to a not-invasive It allows determining such events in a real time and semi automatic context, thanks to a not invasive technique, compatible with the usual course of the matches. technique, compatible with the usual course of the matches. Background Background The invention refers to soccer matches, in which some specifically developed technologies can support The invention refers to soccer matches, in which some specifically developed technologies can support match management for an objective evaluation of the dynamic events that occur during matches match management for an objective evaluation of the dynamic events that occur during matches themselves, in a completely non invasive and precise way. themselves, in a completely non-invasive and precise way. Technology Technology The system uses high frame-rate cameras, that acquire up to 1000 images per second, in order to capture The system uses high frame rate cameras, that acquire up to 1000 images per second, in order to capture highly dynamic events. Software modules have been developed to detect the position of the moving highly dynamic events. Software modules have been developed to detect the position of the moving objects; the results are usable by means of a multimedia console. objects; the results are usable by means of a multimedia console. Advantages and Applicatons Advantages and Applications The system allows to overcome the limit of the human visual system that suffer from perspective errors, The system allows to overcome the limit of the human visual system that suffer from perspective errors, low temporal resolution and occlusions. Allowing an unlimited field of view, it avoids perspective errors as low temporal resolution and occlusions. Allowing an unlimited field of view, it avoids perspective errors as several points of view are used. Furthermore, reaction time is negligible. several points of view are used. Furthermore, reaction time is negligible. The system is not invasive for the field structures. The system is not invasive for the field structures.
