Abstract

La présente invention concerne un procédé et un système de reconnaissance de voie de circulation qui comportent les étapes suivantes : le traitement préalable d'une image avant de véhicule obtenue par un module de caméra attaché à un véhicule afin d'obtenir une image intégrale ; l'extraction d'un point de voie de circulation candidate par convolution de l'image intégrale et d'un modèle de point de voie de circulation candidate lorsqu'une équation de voie de circulation précédente n'existe pas ; la découverte d'une équation de voie de circulation primaire d'un groupe de voies de circulation candidates, qui est obtenu par conversion des coordonnées des points de voie de circulation candidate extraits en coordonnées d'un système de coordonnées à distance vraie et ensuite par regroupement, et la sélection, parmi les groupes potentiels de voie de circulation trouvés, une paire de groupes de voie de circulation candidate qui satisfait les conditions prédéterminées à titre de paire de voies de circulation initialement détectées.
