Abstract
An object of the invention is to reduce a calculation performance required for an obstacle detection device while maintaining an obstacle detection range in a wide range in an obstacle detection system where external sensor data mounted in a track transport system is used. Therefore, in the invention, an obstacle detection system includes: an external sensor configured to monitor surroundings of a train; and at least two or more obstacle detection processing units configured to perform obstacle detection processing for detecting an obstacle by using sensor data acquired by the external sensor, in which the obstacle detection processing is distributed to the two or more obstacle detection processing units according to sensor information of the sensor data.
