Abstract[English]
The present application relates to a method for determining an object in the surroundings of a vehicle based on an ultrasonic signal. The method comprises obtaining an ultrasonic sample set based on ultrasonic data collected during vehicle movement, wherein each ultrasonic sample in the ultrasonic sample set comprises sample point plane coordinates and sample point ultrasonic signal features; performing a gridding process on the ultrasonic sample set based on the sample point plane coordinates of each ultrasonic sample and at least a portion of the ultrasonic signal features of the sample point; and clustering the gridded ultrasonic sample set based on the gridded sample point plane coordinates of each ultrasonic sample and the at least portion of the ultrasonic signal features of the sample point to obtain one or more sample clusters, wherein each sample cluster corresponds to an object in the surroundings of the vehicle.[French]
La présente invention concerne un procédé de détermination d'un objet dans l'environnement d'un véhicule sur la base d'un signal ultrasonore. Le procédé consiste à obtenir un ensemble d'échantillons ultrasonores sur la base de données ultrasonores collectées pendant un mouvement de véhicule, chaque échantillon ultrasonore dans l'ensemble d'échantillons ultrasonores comprenant des coordonnées planaires de point d'échantillon et des caractéristiques de signal ultrasonore de point d'échantillon ; réaliser un processus de maillage sur l'ensemble d'échantillons ultrasonores sur la base des coordonnées planaires de point d'échantillon de chaque échantillon ultrasonore et d'au moins une partie des caractéristiques de signal ultrasonore du point d'échantillon ; et regrouper l'ensemble d'échantillons ultrasonores maillés sur la base des coordonnées planaires maillées de point d'échantillon de chaque échantillon ultrasonore et de l'au moins une partie des caractéristiques de signal ultrasonore du point d'échantillon pour obtenir un ou plusieurs groupes d'échantillons, chaque groupe d'échantillons correspondant à un objet dans l'environnement du véhicule.
