Abstract

L'invention concerne un procédé de tracé d'un itinéraire parcouru par un véhicule ferroviaire. Au moyen d'une caméra disposée sur le véhicule ferroviaire, des images d'un itinéraire parcouru par le véhicule ferroviaire sont capturées. En fonction des images de caméra, l'itinéraire parcouru est analysé à partir du véhicule ferroviaire par rapport à des points d'itinéraire pertinents. Au moyen d'une unité radio mobile disposée sur le véhicule ferroviaire, la position du véhicule ferroviaire est déterminée en continu. À partir du véhicule ferroviaire, les points d'itinéraire pertinents sont reliés à des positions associées et à des données cartographiques disponibles afin de former un tracé d'itinéraire.
