To provide an obstacle detection device for a railway capable of defining a correct inside/outside determination frame even if an object, which easily reflects electric waves or light, exists in the vicinity of a ground marker.SOLUTION: An obstacle detection device for a railway determines presence/absence of an obstacle in inside/outside determination frames with use of a camera and a sensor by installing ground markers on both sides of a railway track and using the ground markers as the inside/outside determination frames. The ground marker 6 has a recognition surface 62a including a combination of reflection (a reflection plate 61) and absorption (a switching plate 62) or transmission of electromagnetic waves. Installation of the ground markers on both sides of the railway track facilitates discrimination of an object easily reflecting the electric waves and light, which exist in the vicinity of the ground markers, from the ground markers, thereby making it possible to define the inside/outside determination frames correctly.SELECTED DRAWING: Figure 3
【課題】地上マーカー付近に電波や光を反射しやすい物体が存在しても、正しい内外判定枠を定義できる鉄道用障害物検知装置を提供する。【解決手段】鉄道用障害物検知装置は、鉄道軌道の両側に地上マーカーを設置し、当該地上マーカーを内外判定枠とすることで、カメラとセンサで内外判定枠内の支障の有無を判定する。そして、地上マーカー6は、電磁波の反射(反射板61)と吸収(切替板62)又は透過とを組み合わせた認識面62aを有することを特徴とする。この地上マーカーを鉄道軌道の両側に設置することで、地上マーカー付近に存在する電波や光を反射しやすい物体と地上マーカーとの識別が容易になり、正しい内外判定枠を定義できる。【選択図】図3
