Abstract
(EN)
The present invention provides a data collection system comprising: a camera; a location module; a plurality of sensors; and a first processor communicatively coupled to the camera and the location module, the first processor programmed to: obtain a plurality of frames from the camera; obtain a plurality of locations from the location module; obtain a plurality of data measurements from the plurality of sensors; apply a previously trained first neural network model for identifying problematic road segments to frames captured by the camera; and if the first neural network model indicates that a frame is a problematic road segment, save the frame in association with a location provided by the location module.

La présente invention concerne un système de collecte de données comprenant : une caméra ; un module de localisation ; une pluralité de capteurs ; et un premier processeur couplé en communication à la caméra et au module de localisation, le premier processeur étant programmé pour : obtenir une pluralité de trames à partir de la caméra ; obtenir une pluralité d’emplacements à partir du module de localisation ; obtenir une pluralité de mesures de données à partir de la pluralité de capteurs ; appliquer un premier modèle de réseau neuronal précédemment entraîné pour identifier des segments de route problématiques aux trames capturées par la caméra ; et si le premier modèle de réseau neuronal indique qu’une trame est un segment de route problématique, enregistrer la trame en association avec un emplacement fourni par le module de localisation.
