Title
(EN) SYSTEM AND METHOD FOR AUTOMATIC MONITORING OF PAVEMENT CONDITION
(FR) SYSTÈME ET PROCÉDÉ DE SURVEILLANCE AUTOMATIQUE D'ÉTAT DE CHAUSSÉE
Abstract
(EN) Various embodiments are provided herein for a system and method for automatic monitoring of pavement condition. In at least some embodiments provided herein, there is provided a method for assessing a condition of a pavement segment, the method comprising: analyzing, using a trained machine learning model, an image of the pavement segment; generating, by the machine learning model, an output comprising one or more identified first pavement distresses in the pavement segment; analyzing accelerometer data associated with the pavement segment; based on the analyzing, determining one or more identified second pavement distresses in the pavement segment; and based on the one or more identified first and second pavement defects, determining pavement condition data associated with the pavement segment.
(FR) Divers modes de réalisation de l'invention concernent un système et un procédé de surveillance automatique de l'état d'une chaussée. Dans au moins certains modes de réalisation, la présente invention concerne, l'invention concerne un procédé d'évaluation d'un état d'un segment de chaussée, le procédé comprenant : l'analyse, à l'aide d'un modèle d'apprentissage machine entraîné, d'une image du segment de chaussée ; la génération, par le modèle d'apprentissage machine, d'une sortie comprenant un ou plusieurs premiers défauts de chaussée identifiés dans le segment de chaussée ; l'analyse des données d'accéléromètre associées au segment de chaussée ; sur la base de l'analyse, la détermination d'un ou de plusieurs seconds défauts de chaussée identifiés dans le segment de chaussée ; et sur la base du ou des premier et second défauts de chaussée identifiés, la détermination des données d'état de chaussée associées au segment de chaussée.
