Department of Engineering, ICT and Technologies for Energy and Transport Patent Title A system to auƚŽŵĂƟĐĂůůy detect sport eǀents. Ref. CNR 1731 Assignee(s): CNR CNR InsƟƚute: ISSIA Main Inventor: Arcangelo Distante Countries: EP, US, JP Priority date: 03/03/2006 Abstract This inǀeŶƟŽn aims to introduce new technologies able to detect in real Ɵme Goal/No Goal ĞǀĞŶƚƐ during soccer matches and point out them to the referee or linesman. The system does not require neither modiĮcĂƟŽn of the ball or Įxed installĂƟon in the playing-Įeld components (posts͕ crossbar͕ etc) nor suspension of the match. It auƚŽŵĂƟĐĂlly detect Goal/no Goal eǀents and can support the Įnal decision upon said eǀents by match management. Background The inǀeŶƟon refers to soccer matches͕ in which some ƐƉĞĐŝĮĐĂůůLJ ĚĞǀĞůŽƉĞĚ ƚĞĐŚŶŽůŽŐŝĞƐ ĐŽŶ ƐƵƉƉŽƌƚ match management for an objĞĐƟǀe eǀaluĂƟon of the dynamic eǀents that occur during matches themselǀes͕ in a completely non-inǀasiǀe͕ auƚŽŵĂƟĐ and precise way. Technology The system uses 4 digital high performance cameras (capable to process and record up to 200 images per second) placed on the infrastructure of the stadium with the ŽƉƟcal axes parallel to the post plane.

The goal eǀent is communicated by radio͕ in reĂůͲƟŵe͕ to the referee with no game interrƵƉƟŽn. Advantages and ApplicaƟŽŶs The system allows to oǀercome the limit of the human ǀisual system that suīĞƌ from perspeĐƟǀe errors͕ low temporal resŽůƵƟŽn and occlusions. The proposed systems͕ instead͕ considering the muůƟƉůe ǀiews of the same scene and the special ůŽĐĂƟŽn of the high resŽůƵƟon digital cameras͕ guarantees no perspeĐƟǀĞ errors͕ high temporal resŽůƵƟŽn and occlusion ĂǀŽŝĚĂnce. The system is not inǀasiǀe for the ĮĞůĚ structures. Development stage The system has been deǀeloped as a prototype and has been installed into the Udine stadium for real ǀalidĂƟon and for the approǀal by FIFA. 53
