By means of this measuring unit all game points can be monitored or calculated. Due to the mobility of the measuring unit along the edge of the field, it is particularly possible to detect offside positions during a football match.
  • no cameras are provided on a framework of a gate. According to a further technology, it is known to provide so-called beam gratings or a light barrier pattern on the post or on the slat of a goal, so that the passage through a goal line level can be recognized by a ball.

  • WO 2011/006989 A1 shows an apparatus and a method for detecting game events in the immediate vicinity of a goal, whereby a goal can be recognized during a football game. Above a framework of a gate and slightly offset behind a goal line level, a camera is installed by means of which it can be detected whether a game body has completely crossed the goal line level. However, no cameras are provided which are located directly on or within a framework of the gate and may additionally monitor either the goal line level and / or an area adjacent to the goal.
  • the detection of a gate is possible not only by means of a camera but also by means of a sensor technology, according to which there is a transmitter or the like in the ball. Accordingly, when crossing a goal line level, a signal is sent from the ball to at least one receiver attached to a post or slat of the goal, thereby detecting a goal.

In a further dependency of the exact position or trajectory of the game body relative to the goal, it is possible in this context to select from the first group of cameras a targeted camera which guarantees the best viewing angle on the game body or has the smallest distance to the game body that accordingly only the pictures of this selected camera of the first group are used for the desired TV pictures.

Abstract

L'invention concerne un système et un procédé de détection de but, comprenant un premier groupe (A) d'une pluralité de caméras qui sont disposées au moins en partie sur ou dans un encadrement d'un but (3) et qui génèrent des images d'une zone voisine du but, un deuxième groupe (B) d'une pluralité de caméras (B1-B7) qui sont disposées chacune à distance du but (3), en particulier en dehors d'un terrain de jeu, et qui permettent de surveiller un plan de ligne de but délimité par l'encadrement du but, et au moins un module calculateur (13) avec lequel les caméras du premier groupe (A) et du deuxième groupe (B) sont en liaison de signal et par lequel elles peuvent être commandées. Le module calculateur (13) peut traiter au moins les données d'images des caméras (B1‑B7) du deuxième groupe (B) et, sur la base de ces données d'images, générer un signal de décision de but lorsqu'un accessoire de jeu venant de la direction du terrain de jeu a complètement franchi le plan de ligne de but et que, en ce qui concerne le traitement des données d'images des caméras (B1‑B7) du deuxième groupe (B), une tolérance d'erreur passe en dessous d'une valeur prédéfinie, le fonctionnement d'au moins une caméra du premier groupe (A) pouvant être commandé en fonction des données d'images des caméras (B1-B7) du deuxième groupe (B).
