Abstract
DISPOSITIF DE DETECTION DE RELIEFS A LA SURFACE DU SOL POUR DISPOSITIF ROULANT ELECTRIQUE ET DISPOSITIF ROULANT ELECTRIQUE ASSOCIE Un aspect de l’invention concerne un dispositif de détection de reliefs à la surface du sol pour dispositif roulant électrique, comportant au moins un télémètre laser (100) comprenant : au moins un émetteur de faisceaux laser (101) configuré pour émettre une pluralité de faisceaux laser (FL1) en direction du sol ; un capteur (102) configuré pour imager chaque faisceau laser rétrodiffusé (FR1) ; un filtre interférentiel (103) configuré pour ne laisser passer qu’un intervalle réduit de longueurs d’onde ; un objectif (104) configuré pour focaliser sur le capteur (102) les faisceaux laser rétrodiffusés (FR1) ; un calculateur (107) configuré pour détecter les reliefs à la surface du sol par triangulation laser ; la longueur d’onde de chaque faisceau laser (FL1) étant choisie en fonction de l’angle d’émission (θ) du faisceau laser (FL1) pour que chaque faisceau laser rétrodiffusé (FR1) passe à travers le filtre interférentiel (103).
