Obstacle-free range determination for rail track maintenance vehicles
Maire, Frederic D. & Bigdeli, Abbas (2010) Obstacle-free range determination for rail track maintenance vehicles. In 11th International Conference on Control, Automation, Robotics and Vision (ICARCV 2010), 7-10 Decembre 2010, Grand Copthorne Waterfront Hotel, Singapore.
Maintenance trains travel in convoy. In Australia, only the first train of the convoy pays attention to the track sig- nalization (the other convoy vehicles simply follow the preceding vehicle). Because of human errors, collisions can happen between the maintenance vehicles. Although an anti-collision system based on a laser distance meter is already in operation, the existing system has a limited range due to the curvature of the tracks. In this paper, we introduce an anti-collision system based on vision. The two main ideas are, (1) to warp the camera image into an image where the rails are parallel through a projective transform, and (2) to track the two rail curves simultaneously by evaluating small parallel segments. The performance of the system is demonstrated on an image dataset.
