Abstract

La présente invention concerne un procédé d’identification de zones roulables dans au moins une image d’un terrain, caractérisé en ce qu’il comprend l’implémentation des étapes suivantes dans une unité de traitement (4) : - apprentissage supervisé d’au moins un réseau de neurones (R2), à partir d’une base de données d’apprentissage comprenant des images d’apprentissages de terrain ayant été annotées par au moins deux opérateurs en vue d’identifier des zones roulables, - segmentation au moyen de l’au moins un réseau de neurones (R2), d’une image d’entrée (I1) pour obtenir une carte probabiliste (I3) de présence d’au moins une zone roulable dans ladite image d’entrée (I1), ladite segmentation comprenant une estimation d’une probabilité de présence d’une zone roulable dans l’image d’entrée (I1), de manière à obtenir une carte probabiliste (I3) définie par une matrice dont chaque élément correspond à une probabilité de présence d’au moins une zone roulable sur un pixel de l’image d’entrée (I1).
