Abstract: front page image
(EN) Example methods and systems for detecting weather conditions using vehicle onboard sensors are provided. An example method includes receiving laser data collected for an environment of a vehicle, and the laser data includes a plurality of laser data points. The method also includes associating, by a computing device, laser data points of the plurality of laser data points with one or more objects in the environment, and determining given laser data points of the plurality of laser data points that are unassociated with the one or more objects in the environment as being representative of an untracked object. The method also includes based on one or more untracked objects being determined, identifying by the computing device an indication of a weather condition of the environment.
(FR) Des exemples de l'invention portent sur des procédés et sur des systèmes pour détecter des conditions météorologiques à l'aide de capteurs embarqués dans un véhicule. Un exemple de procédé met en œuvre la réception de données de laser collectées pour un environnement d'un véhicule, et les données de laser comprennent une pluralité de points de données de laser. Le procédé met également en œuvre l'association, par un dispositif informatique, de points de données de laser de la pluralité de points de données de laser à un ou plusieurs objets dans l'environnement, et la détermination de points de données de laser donnés de la pluralité de points de données de laser qui ne sont pas associés au ou aux objets dans l'environnement comme étant représentatifs d'un objet non suivi. Le procédé met également en œuvre, sur la base d'un ou de plusieurs objets non suivis qui sont déterminés, l'identification par le dispositif informatique d'une indication d'une condition météorologique de l'environnement.
