Abstract
An obstacle detection device to be installed on a train includes: a sensor that monitors a monitoring region and outputs a monitoring result; an obstacle detection unit that determines presence or absence of an obstacle on a route on the basis of the monitoring result, and outputs a detection result; a monitoring distance determination unit that uses the detection result to determine a monitoring distance from the train to a reference; and a monitoring region determination unit that determines a monitoring region by using the monitoring distance, in which, when changing the monitoring distance, the monitoring distance determination unit acquires the monitoring region, and changes the monitoring distance such that a part of a monitored first monitoring region overlaps with a part of a second monitoring region based on the changed monitoring distance, in order not to generate a region not monitored.
