Innovative remote video monitoring of railway track displacements
This paper reports the initial development and testing of an innovative technique for measuring rail displacements that combines remote video monitoring with particle image velocimetry (PIV). A webcam combined with a small telescope is used to monitor rail movements. Results from a laboratory trial, in which the movements of a hydraulic actuator were monitored, demonstrate that the system can measure peak-to-peak displacements of the actuator to within 0.1mm from 15m away. Results from a section of railway track near Crewe are also reported.

Abstract

This paper reports the initial development and testing of an innovative technique for measuring rail displacements that combines remote video monitoring with particle image velocimetry (PIV). A webcam combined with a small telescope is used to monitor rail movements. Results from a laboratory trial, in which the movements of a hydraulic actuator were monitored, demonstrate that the system can measure peak-to-peak displacements of the actuator to within 0.1mm from 15m away. Results from a section of railway track near Crewe are also reported.
