Department of Engineering, ICT and Technologies for Energy and Transport Patent Title Method and system for event deteĐƟon and monitoring in a speciĮc area in sport Įeld. Ref. CNR 1876 Assignee(s): CNR - FIGC CNR InsƟƚute: ISSIA Main Inventor: Arcangelo Distante Countries: IT Priority date: 01/10/2007 Abstract This inveŶƟŽn refers to an intelligent vision-based system ǁŚŝĐŚ is able to acquire, record and process image sequences in order to detect ĐƌŝƟĐĂů events in a speciĮc area; in ƉĂƌƟĐƵůĂƌ, the system is useful for monitoring the “penalty area” during a soccer match. It ĂůůŽǁs determining such events in a ƌĞĂůͲƟŵe and semi-auƚŽŵĂƟĐ context, thanks to a not-invasive technique, ĐŽŵƉĂƟďůĞ ǁŝƚh the usual course of the matches. Background The inveŶƟon refers to soccer matches, in ǁhich some speciĮcally developed technologies con support match management for an objĞĐƟve evaluaƟon of the dynamic events that occur during matches themselves, in a completely non-invasive and precise ǁĂy. Technology The system uses high frame-rate cameras, that acquire up to 1000 images per second, in order to capture highly dynamic events. ^ŽŌǁĂƌĞ modules have been developed to detect the posŝƟon of each moving objects and their ŝŶƚĞƌĂĐƟŽn; the results are usable by means of a ŵƵůƟŵĞĚŝa console. Advantages and ApplicaƟŽŶs The system ĂůůŽǁƐ to overcome the limit of the human visual system that suīĞƌ from perspeĐƟve errors, loǁ temporal resŽůƵƟŽn and occlusions. AůůŽǁŝŶŐ an unlimited ĮĞůĚ of ǀŝĞǁ͕ it avoids persƉĞĐƟve errors as several points of vŝĞǁ are used. Furthermore, ƌĞĂĐƟŽn Ɵŵe is negligible. The system is not invasive for the Įeld structures. Development stage The system has been developed as a prototype and has been installed into the Udine stadium for real vĂůŝĚĂƟŽn. 55
