Disclosed are a method for estimating the moving direction of a front vehicle using radar and an apparatus thereof. The method for estimating the moving direction of a front vehicle using radar comprises the steps of: (a) acquiring a radar detection result and then signal-processing the radar detection result to acquire front vehicle information; (b) converting the front vehicle information into point cloud data in a 2D space; (c) converting the point cloud data into an image by preprocessing the point cloud data; and (d) outputting progress direction and angle information of a front vehicle by applying the converted image to a trained deep learning model.
L'invention divulgue un procédé d'estimation de la direction de déplacement d'un véhicule avant à l'aide d'un radar et un appareil associé. Le procédé d'estimation de la direction de déplacement d'un véhicule avant à l'aide d'un radar comprend les étapes consistant à : (a) acquérir un résultat de détection radar puis traiter par signal le résultat de détection radar pour acquérir des informations de véhicule avant ; (b) convertir les informations de véhicule avant en données de nuage de points dans un espace 2D ; (c) convertir les données de nuage de points en une image par prétraitement des données de nuage de points ; et (d) délivrer des informations de direction de progression et d'angle d'un véhicule avant par application de l'image convertie à un modèle d'apprentissage profond entraîné.
