Problems solved by technology

[0003] However, these devices are limited to the setting of the position where obstacles are likely to occur in the advancing path of the railway vehicle, and it is difficult to cover the entire advancing path of the railway vehicle.
In addition, these devices require the cooperation of ground equipment and vehicle equipment to detect obstacles, so there is a concern that the system will become more complex and bulky

no. 1 Embodiment approach

[0026] figure 1 It is a figure which shows an example of the schematic structure of the railway vehicle of 1st Embodiment. Such as figure 1 As shown, the railway vehicle RV of this embodiment includes a sensor 10 , a running obstacle detection device 20 , a recording device 30 and a display device 40 . The sensor 10 is an example of an imaging unit provided so as to be able to image the traveling direction of the railway vehicle RV. In the present embodiment, the sensor 10 is provided so as to be able to image an imaging range including the rail R existing in the traveling direction of the rail vehicle RV. The running obstacle detection device 20 is an example of an obstacle detection device that detects an obstacle that hinders the running of the rail vehicle RV. The recording device 30 stores detection results of obstacles detected by the traveling obstacle detection device 20 . The display device 40 displays various information such as an image captured by the sensor 10...

no. 2 Embodiment approach

[0068] The present embodiment is an example in which a monitoring area is enlarged in a predetermined section in a traveling section in which a railway vehicle travels. In the following description, the description of the same configuration as that of the first embodiment will be omitted.

[0069] Figure 9 It is a figure which shows an example of the functional structure of the running obstacle detection device with which the railway vehicle of 2nd Embodiment is equipped. Such as Figure 9 As shown, in the present embodiment, the railway vehicle RV includes the position measurement device 60 in addition to the sensor 10 , the running obstacle detection device 90 , the display device 40 , and the recording device 30 . The position measurement device 60 is a position measurement unit that measures the running position of the rail vehicle RV. Here, the position measuring device 60 uses a speed generator (TG) and a satellite positioning system (GNSS). The traveling obstacle d...

Abstract

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.

Description

technical field [0001] Embodiments of the present invention relate to an obstacle detection device. Background technique [0002] When running railway vehicles such as trains and trains, in order to ensure the safety of the railway vehicles, it is necessary to check whether there are obstacles on the road ahead. In the section where obstacles are likely to occur on the way forward of the railway vehicle due to passengers or luggage falling from the platform of the station, cars and bicycles at the crossing, etc., there are platform guardrails and crossing barriers to prevent obstacles from entering. , pressure-sensitive pads that detect the presence of obstacles, image recognition devices that recognize images of obstacles, etc. Station platform drop detection devices, optical or loop coil types that detect the presence of obstacles in crossings, etc. crossing obstacle detection device, etc. In addition, in a section where obstacles are likely to occur on the roadway of th...
