Abstract

Procédé d’aide à la détection d’éléments, dispositif et plateforme associés La présente invention concerne un procédé d’aide à la détection d’éléments dans un environnement, le procédé comprenant à chaque instant les étapes de : - acquisition d’une première image de l’environnement ayant une première résolution et un premier champ de vision, - détection d’éléments imagés sur la première image, - classification de chaque élément détecté pour obtenir une classification initiale de l‘élément, - acquisition d’au moins une deuxième image d’au moins l’un des éléments détectés ayant une deuxième résolution et un deuxième champ de vision, la deuxième résolution étant supérieure à la première résolution, le deuxième champ de vision étant plus restreint que le premier champ de vision, et - réévaluation pour chaque élément détecté imagé sur la deuxième image, de la classification de l‘élément en fonction de la deuxième image pour obtenir une classification réévaluée de l‘élément. Figure pour l'abrégé : 1Method for assisting the detection of elements, associated device and platform The present invention relates to a method for assisting the detection of elements in an environment, the method comprising at each instant the steps of: - acquisition of a first image of the environment having a first resolution and a first field of view, - detection of elements imaged on the first image, - classification of each element detected to obtain an initial classification of the element, - acquisition of at least one second image of at least one of the detected elements having a second resolution and a second field of view, the second resolution being greater than the first resolution, the second field of view being more restricted than the first field of view, and - reevaluating for each detected item imaged on the second image, classifying the item based on the second image to obtain a reevaluated classification of the item.
