An obstacle detecting device according to an embodiment of the present invention is provided with an acquiring unit, a rail detecting unit, a monitored area setting unit, an obstacle detecting unit, and an output unit. The acquiring unit acquires a visible light image obtained by capturing an image in the direction of travel of a railway vehicle by means of an image capturing unit of the railway vehicle, and a distance image which makes it possible to identify the distance to an object present within an image capturing range of the image capturing unit. The rail detecting unit detects a rail on which the railway vehicle is traveling, from the visible light image. The monitored area setting unit sets a three-dimensional monitored area which is defined, with respect to the visible light image, by the vehicle gauge of the railway vehicle or the construction gauge, with the rail as a reference. The obstacle detecting unit detects an obstacle which is present within the monitored area and which would interfere with the travel of the railway vehicle, on the basis of range information making it possible to identify the range of distances to the monitored area based on the visible light image, and on the basis of the distance image. The output unit outputs the obstacle detection results.

    实施方式的障碍物检测装置具备取得部、轨道检测部、监测区域设定部、障碍物检测部以及输出部。取得部取得可见光图像及距离图像,该可见光图像是由铁道车辆所具有的拍摄部对铁道车辆的行进方向进行拍摄而得到的,该距离图像能够确定到在拍摄部的拍摄范围存在的物体为止的距离。轨道检测部从可见光图像中检测铁道车辆行驶的轨道。监测区域设定部以轨道为基准,对可见光图像设定由铁道车辆的车辆界限或建筑界限规定的立体的监测区域。障碍物检测部根据基于可见光图像的能够确定到监测区域为止的距离的值域的值域信息和距离图像,检测存在于监测区域内且成为铁路车辆的行驶的障碍的障碍物。输出部输出障碍物的检测结果。
