Abstract

La présente invention concerne un procédé de surveillance de véhicule, ainsi qu'un appareil, un dispositif et un système associés. Le système comprend : un serveur, une première caméra à une entrée, une seconde caméra ayant une plage de photographie couvrant au moins une première porte de barrière, et une troisième caméra ayant une plage de photographie couvrant une pluralité d'espaces de stationnement. La première caméra détecte, dans une image acquise, un numéro de plaque d'immatriculation d'un véhicule entrant, et envoie le numéro de plaque d'immatriculation au serveur. Le serveur envoie un premier message de notification contenant le numéro de plaque d'immatriculation à la seconde caméra, détermine des informations de recommandation d'espace de stationnement selon des images acquises par la seconde caméra et la troisième caméra, et notifie au véhicule les informations de recommandation d'espace de stationnement. La seconde caméra détecte, à partir des images acquises, le véhicule situé au niveau de la première porte de barrière, et associe le numéro de plaque d'immatriculation au véhicule et suit le véhicule. La troisième caméra suit le véhicule en fonction de la matrice d'homographie entre les caméras. Si la caméra détecte que le véhicule est arrêté au niveau d'un espace de stationnement cible, un second message de notification indiquant une position de stationnement du véhicule est envoyé au serveur pour guider le stationnement du véhicule.
