Abstract

Système d’identification des panneaux de signalisation routière, comprenant : - au moins un dispositif de détection radar (1) ou lidar, - des dispositifs d'affichage incluant une pluralité de panneaux (2) de signalisation routière, chaque panneau ayant au moins une face d’affichage, chaque dispositif d'affichage comprenant un ou plusieurs dièdres ou trièdres (3) sur la face d’affichage, chacun de ces dièdres ou trièdres présentant un écho radar ou lidar de surface équivalente supérieure à un seuil prédéterminé, au vu du dispositif de détection radar ou lidar, - Au moins une caméra vidéo (7), Caractérisé en ce que la caméra vidéo utilise le résultat du dispositif de détection radar ou lidar pour circonscrire l'analyse d'images vidéo sur les positions où un panneau de signalisation ou un dispositif d'affichage a été identifié par le dispositif de détection radar. Figure pour l’abrégé : Fig. 3System for identifying road signs, comprising: - at least one radar (1) or lidar detection device, - display devices including a plurality of road signs (2), each panel having at least one display face, each display device comprising one or more dihedrons or trihedrons (3) on the display face, each of these dihedrons or trihedrons having a radar or lidar echo of equivalent area greater than a predetermined threshold, in view of the radar or lidar detection device, - At least one video camera (7), Characterized in that the video camera uses the result of the radar or lidar detection device to limit the analysis of video images on the positions where a panel signaling device or a display device has been identified by the radar detection device.
