Abstract

L'invention concerne un procédé pour afficher sur un appareil de visualisation des places de stationnement libres et de préférence également occupées, procédé selon lequel plusieurs caméras fournissent des indices de représentation de places de stationnement. Les coordonnées géographiques des places de stationnement se trouvant dans la portée visuelle de la caméra sont mémorisées dans une unité de reconnaissance, cette dernière associant à chaque place de stationnement un statut d'occupation, en fonction des indices de représentation, ledit statut d'occupation indiquant si une place de stationnement est libre ou non, l'unité de reconnaissance fournit ledit statut d'occupation assorti des coordonnées géographiques correspondantes à une unité d'émission et ladite unité d'émission envoie le statut d'occupation assorti des coordonnées géographiques correspondantes à l'appareil de visualisation.
