Title
(EN) METHOD FOR READING INFORMATION RELATED TO VERTICAL TRAFFIC SIGNS, RELATED DEVICE, AND USE THEREOF
(FR) PROCEDE DE RELEVE D'INFORMATIONS RELATIVES A DES PANNEAUX DE SIGNALISATION VERTICALE, DISPOSITIF ASSOCIE ET APPLICATION
Abstract
(EN)
The present invention mainly relates to a method for reading, from a moving vehicle, information related to a vertical traffic sign, characterized in that it includes at least the steps of detecting said sign (5), locating the sign (5) in relation to said vehicle (1), estimating the variation in the position of the sign (5) in relation to the moving vehicle (1), and acquiring the image of the rear surface of the sign (5) when, after the estimation of the previous step, the location of said sign (5) is estimated to be in the display window of an image acquisition apparatus (8) arranged on the vehicle (1), thus rendering the approval mark on the rear surface of the sign readable. The invention also relates to a device for implementing said method and to the use of said method for mapping the age of vertical traffic signs.
(FR)
La présente invention concerne principalement un procédé de relevé d'informations relatives à un panneau de signalisation verticale depuis un véhicule en mouvement, caractérisé en ce qu'il comprend au moins les étapes de détection du dit panneau (5), de localisation du panneau (5) relativement au dit véhicule (1), d'estimation de l'évolution de la position du panneau (5) relativement au véhicule en mouvement (1), d'acquisition de l'image de la face arrière du panneau (5) lorsque, d'après l'estimation de l'étape précédente, le dit panneau (5) est estimé se trouver dans la fenêtre de visualisation d'un appareil d'acquisition d'image (8) disposé sur le véhicule (1), ce dont il résulte que la marque d'homologation de la face arrière du panneau est susceptible d'être relevée. L'invention porte également sur un dispositif de mise en œuvre de ce procédé et sur l'application de ce procédé pour établir une cartographie de l'âge des panneaux de signalisation verticale.
