Obstacle detection system

摘要

A system (10) for alerting a controller of a track-led vehicle of the presence of an obstacle in a track of the vehicle. At least one sensor including a video camera (12) is mounted on the vehicle such that its orientation is automatically adjusted relative to the vehicle for sensing a field of view of the track in front of the vehicle so as to produce successive video images thereof each representative of a respective section of track ahead of the vehicle, and an obstacle detection device (14) coupled to the video camera (12) processes successive video images produced thereby so as to produce an obstacle detect signal consequent thereto. An obstacle avoidance unit (16) mounted in the vehicle is coupled to the obstacle detection device and is responsive to the obstacle detect signal for producing an obstacle avoidance signal. <IMAGE> <IMAGE>
