TRACK GAUGE MEASUREMENT DEVICE AND TRACK GAUGE MEASUREMENT METHOD
PROBLEM TO BE SOLVED: To provide a track gauge measurement device with which it is possible to efficiently measure a track gauge with excellent reproducibility and with high accuracy, together with the absolute coordinates of a measured place.SOLUTION: The track gauge measurement device comprises: a receiver for receiving a signal from a satellite constituting a Global Navigation Satellite System (GNSS); a laser scanner which, while scanning a laser beam laterally, radiates the laser beam toward a rail, and receives the laser beam reflected by and returned from the rail; and an arithmetic unit for calculating the position and inclination of the rail using the position acquired on the basis of the signal from the satellite and the distance and bearing from the laser scanner to the rail that is obtained on the basis of the laser scanner, extracting a group of laser points used in measuring the track gauge of the rail from the position and inclination of the rail, and measuring the track gauge.SELECTED DRAWING: Figure 2
