Abrégé
(EN) The present disclosure relates to a state detection method and device for signal indicator, a driving control method and device, the state detection method for signal indicator includes: detecting the target area in the target image, and determining the first feature value of the pixel point in the target area, wherein the target area includes at least one signal indicator with different display states; performing clustering processing on the pixel point in the target area based on the first feature value to obtain multiple clusters for the pixel point; determining the display state of the signal indicator based on the obtained multiple clusters.
(FR) La présente invention concerne un procédé et un dispositif de détection d'état pour un indicateur de signal, un procédé et un dispositif de commande de conduite, le procédé de détection d'état pour un indicateur de signal comprenant les étapes consistant à : détecter la zone cible dans l'image cible et déterminer la première valeur de caractéristique du point de pixel dans la zone cible, la zone cible comprenant au moins un indicateur de signal ayant différents états d'affichage ; effectuer un traitement de groupement sur le point de pixel dans la zone cible sur la base de la première valeur de caractéristique pour obtenir de multiples groupes pour le point de pixel ; déterminer l'état d'affichage de l'indicateur de signal sur la base des multiples groupes obtenus.
