Abstract
A rail position measurement device that measures a three-dimensional position of a rail using a measurement vehicle includes: a position posture measurement device to measure a position and a posture of the measurement vehicle; and a laser scanner that is a sensor installed on the measurement vehicle so as to be capable of irradiating at least a web and a bottom of a side surface of the rail with laser light and used for measuring the three-dimensional position of the rail.
Claims20
A rail position measurement device that measures a three-dimensional position of a rail using a measurement vehicle, the rail position measurement device comprising:
- a position posture measurement device installed on the measurement vehicle configured to measure a position and a posture of the measurement vehicle;
- a laser scanner that is a sensor installed on the measurement vehicle and configured to irradiate at least a web and a bottom of a side surface of the rail with laser light and used for measuring the three-dimensional position of the rail;
- a laser position adjustment device installed on the measurement vehicle and configured to move a position of the laser scanner in an up-down direction;
- and
- a calculator installed on the measurement vehicle and configured to calculate, based on measurement information of at least one of the laser scanner and the position posture measurement device, a position of the laser scanner such that at least the web and the bottom of the side surface of the rail are irradiated with the laser light.
A calculator that is used for a rail position measurement device that measures a three-dimensional position of a rail using a measurement vehicle, the calculator comprising:
- a position calculator to calculate a scanner position with respect to the rail from measurement information obtained by a laser scanner that is a sensor installed on the measurement vehicle so as to be capable of irradiating at least a web and a bottom of a side surface of the rail with laser light and used for measuring the three-dimensional position of the rail;
- and
- a laser position calculator to compute a movement amount or a scanner position of the laser scanner in an up-down direction on a basis of a calculation result from the position calculator and to transmit information on the movement amount or the scanner position to a laser position adjustment device capable of moving a position of the laser scanner in the up-down direction.
