Abstract:
(EN) Methods and systems for calibrating a plurality of sensors are provided. The method may include capturing, by a plurality of sensors associated with a vehicle, a set of point cloud data indicative of at least one surrounding object as the vehicle travels along a trajectory. The method may also include filtering, by a processor, the set of point cloud data based on coplanarity associated with the set of point cloud data. The method may further include adjusting, by the processor, at least one calibration parameter of the plurality of sensors based on a model using the filtered set of point cloud data. The model may include a weight corresponding to the coplanarity associated with the set of point cloud data.
(FR) L'invention concerne des procédés et des systèmes d'étalonnage d'une pluralité de capteurs. Le procédé peut comprendre la capture, par une pluralité de capteurs associés à un véhicule, d'un ensemble de données de nuage de points indiquant au moins un objet environnant alors que le véhicule se déplace le long d'une trajectoire. Le procédé peut également comprendre le filtrage, par un processeur, de l'ensemble de données de nuage de points sur la base d'une coplanarité associée à l'ensemble de données de nuage de points. Le procédé peut en outre comprendre le réglage, par le processeur, d'au moins un paramètre d'étalonnage de la pluralité de capteurs sur la base d'un modèle, à l'aide de l'ensemble filtré de données de nuage de points. Le modèle peut comprendre un poids correspondant à la coplanarité associée à l'ensemble de données de nuage de points.
