An optical triangulation system using television cameras measures lineside structures to ensure adequate clearances for railway rolling stock. The measuring system is mounted on a railway vehicle and uses white light illumination. Operation is possible at speeds of up to 100 km/h which allows complete routes to be measured in a single shift. Results are referenced with respect to the railway track and are recorded on digital magnetic tape.
