SYSTEM AND METHOD FOR UTILIZING AN INFRA-RED SENSOR BY A MOVING TRAIN

摘要

A method and system for identification of obstacles near railways and for providing alarm to an operator of a train if obstacles constitute threat to the train are disclosed. The system comprise IR sensor disposed at the front of the train facing the direction of travel. The IR sensor receives images of the rails in front of the train. The system comprises pre-stored vibration profile of the train's engine that is used to eliminate influence of the engine's vibrations on the accuracy of the received images. Presence of rails in the received frames is detected based on inherent differences of temperature between the rails and the substrate in the rails' background, such as the railway sleepers and the materials underneath it.

主权项

1. A method for railway obstacle identification, the method comprising:
receiving infrared (IR) images from at least one IR sensor installed on an engine of a train the at least one IR sensor facing the direction of travel; obtaining a vibration profile; filtering effects of vibrations from the IR images based on the vibration profile; deciding, based on pre-prepared rules and parameters, whether the IR images contain image of an obstacle and whether that obstacle forms a threat on the train's travel; and providing an alarm signal if the IR images contain image of an obstacle.
