Abstract
Un système pour inspecter les traverses dune voie ferrée inclut un générateur de lumière, un récepteur optique et un processeur. Le générateur de lumière est orienté pour projeter un faisceau lumineux sur la voie ferrée tout en se déplaçant le long de la voie ferrée dans la direction du train. Le récepteur optique est orienté pour recevoir au moins une partie du faisceau lumineux qui réfléchit de la voie ferrée et est configuré pour générer des données dimage représentatives dun profil dau moins une partie de la voie ferrée. Le processeur est configuré pour analyser les données dimage en appliquant un ou plusieurs algorithmes configurés pour trouver les délimitations dune traverse dune voie ferrée et déterminer une ou plusieurs mesures de létat associées à la traverse de la voie ferrée.
