Abstract

L'invention concerne un procédé de détection de mouvements d'objets sur une aire de stationnement pour véhicules par traitement de prises de vue issues d'au moins une caméra. Pour détecter les mouvements d'un objet, au moins deux prises de vue issues de la caméra sont comparées, les différences entre les prises de vue étant analysées. Si l'achèvement d'un mouvement d'un objet est détecté, la position de l'objet est enregistrée dans une mémoire.
