Abstract:
(EN) Provided are a railway equipment monitoring device and railway equipment monitoring system capable of suppressing influence from changes in external environmental conditions and displaying the state of a pantograph so as to be easy for observer monitoring personnel to see. This railway equipment monitoring device 1 comprises: a stereo camera 11 that comprises two cameras (11a, 11b) and is for capturing images of a pantograph 9 that is a subject, a camera rotation and holding unit 12 for rotatably holding the stereo camera 11, and a control and calculation unit 10 for making the stereo camera 11 shift to each prescribed rotation angle, generating a distance image of the pantograph 9 from the captured images obtained at each rotation angle, and determining the angle by which the camera rotation and holding unit 12 is to rotate the stereo camera 11 on the basis of the distance image of the pantograph.
(FR) La présente invention concerne un dispositif de surveillance d’équipement ferroviaire et un système de surveillance d’équipement ferroviaire permettant de supprimer l’influence de changements des conditions environnementales externes et de présenter l’état d’un pantographe de façon à être facile à visualiser par le personnel de surveillance observateur. Ce dispositif de surveillance d’équipement ferroviaire 1 comprend : une caméra stéréo 11 qui comprend deux caméras (11a, 11b) et est destinée à capturer des images d’un pantographe 9 qui est un sujet, une unité de rotation et de maintien de caméra 12 pour maintenir en rotation la caméra stéréo 11, et une unité de commande et de calcul 10 pour amener la caméra stéréo 11 à se déplacer à chaque angle de rotation prescrit, générer une image de distance du pantographe 9 à partir des images capturées obtenues à chaque angle de rotation, et déterminer l’angle auquel l’unité de rotation et de maintien de caméra 12 doit faire tourner la caméra stéréo 11 sur la base de l’image de distance du pantographe.
(JA) 外部環境条件の変化による影響を抑制し、パンタグラフの状態を監視員に見え易く表示し得る鉄道設備モニタリング装置及び鉄道設備モニタリングシステムを提供する。鉄道設備モニタリング装置1は、2つのカメラ(11a,11b)から構成され、対象物体であるパンタグラフ9を撮像するステレオカメラ11と、ステレオカメラ11を回転可能に保持するカメラ回転保持部12と、ステレオカメラ11を所定の回転角度毎に変化させ、各回転角度にて得られる撮像画像からパンタグラフ9の距離画像を生成し、パンタグラフの距離画像に基づきカメラ回転保持部12によるステレオカメラ11の回転角度を決定する制御演算部10と、を備える。
