Title
(EN) METHOD AND SYSTEM FOR GENERATING BIRD'S EYE VIEW BOUNDING BOX ASSOCIATED WITH OBJECT
(FR) PROCÉDÉ ET SYSTÈME DE GÉNÉRATION D'UN RECTANGLE ENGLOBANT DE VUE DE DESSUS ASSOCIÉ À UN OBJET
Abstract
(EN) A system and method for generating a bounding box for an object in proximity to a vehicle are disclosed. The method includes: receiving a three-dimensional (3D) point cloud representative of an environment; receiving a two-dimensional (2D) image of the environment; processing the 3D point cloud to identify an object cluster of 3D data points for a 3D object in the 3D point cloud; processing the 2D image to detect a 2D object in the 2D image and generate information regarding the 2D object from the 2D image; and when the 3D object and the 2D object correspond to the same object in the environment: generating a bird's eye view (BEV) bounding box for the object based on the object cluster of 3D data points and the information from the 2D image.
(FR) Un système et un procédé de génération d'un rectangle englobant pour un objet à proximité d'un véhicule sont divulgués. Le procédé consiste à : recevoir un nuage de points tridimensionnel (3D) représentant un environnement; recevoir une image bidimensionnelle (2D) image de l'environnement; traiter le nuage de points 3D pour identifier une grappe d'objets de points de données 3D pour un objet 3D dans le nuage de points 3D; traiter l'image 2D pour détecter un objet 2D dans l'image 2D et générer des informations concernant l'objet 2D à partir de l'image 2D; et, lorsque l'objet 3D et l'objet 2D correspondent au même objet dans l'environnement, générer un rectangle englobant de vue de dessus (BEV) pour l'objet sur la base de la grappe d'objets de points de données 3D et des informations à partir de l'image 2D.
