To provide a ground traffic signal recognition device which improves the recognition accuracy of signal indication contents of a ground traffic signal and enhances safety for railways.SOLUTION: The ground traffic signal recognition device includes: a train position detection device that detects a position of a train; a ground traffic signal information storage device that stores installation positions of ground traffic signals along a track on which the train travels and information about the ground traffic signals; a photographing device that photographs an image ahead of the train; and a signal indication recognition device that recognizes signal indications of the ground traffic signals and inputs information about a preceding train of the train received from outside. The signal indication recognition device recognizes the signal indications of the ground traffic signals present in an advancing direction of the train by using the position of the train output by the train position detection device, the installation positions and information of the ground traffic signals output by the ground traffic signal information storage device, and information about the preceding train as auxiliary information that assists in the recognition of the images photographed by the photographing device and the signal indications of the ground traffic signals.SELECTED DRAWING: Figure 1
【課題】地上信号機の信号現示内容の認識精度を向上させ、鉄道向けにより安全性を高めた地上信号機認識装置を提供する。【解決手段】地上信号機認識装置として、列車の位置を検出する列車位置検出装置と、列車が走行する線路沿いの地上信号機の設置位置及び当該地上信号機に関する情報を格納する地上信号機情報記憶装置と、列車の前方の画像を撮影する撮影装置と、地上信号機の信号現示を認識すると共に外部から受信した前記列車の先行列車の情報を入力とする信号現示認識装置とを備え、信号現示認識装置は、列車位置検出装置が出力する列車の位置、地上信号機情報記憶装置が出力する地上信号機の設置位置と情報、撮影装置が撮影した画像及び地上信号機の信号現示の認識を補助する補助情報として先行列車の情報を使用して、列車の進行方向に存在する地上信号機の信号現示を認識する。【選択図】図1
