Train Positioning Using Video Odometry

Siddhartha Ghosh, Robert Whittaker

Research output: Book/ReportCommissioned report


Reliable Data Systems have developed a video-based odometry system that enables trains to measure velocities and distances travelled without the need for trackside infrastructure. The Study Group was asked to investigate ways of improving the accuracy of such a system, and to suggest any improvements that might be made. The work performed in the week followed along these strands: (a) Elimination of errors in video odometry induced by pitch and height; (b) Robust calculation of (i) the train velocity and (ii) the track curvature; (c) Accurate determination of the position of a train on a track by assimilating Curvature information; (d) Determining where on UK’s railway map a train journey takes place, based purely on video odometry and (e) Drawing a track map.
