Abstract

The invention discloses a method for detecting geometry morphology of a railway track. The method includes setting total-station instruments on a railway line by the aid of known control points of the railway line; placing track geometrical morphology detecting equipment on steel rails of a railway; measuring spatial three-dimensional coordinates of centers of prisms and geometrical position data of the track geometrical morphology detecting equipment by the aid of the total-station instruments; and acquiring geometrical morphology data of the railway track where the track geometrical morphology detecting equipment is located according to spatial coordinate data and the geometrical position data. The method for detecting the geometrical morphology of the railway track has the advantages that the measurement accuracy is high, and required railway track geometrical morphology detectors are simple in structure and can be mounted conveniently and quickly.

Description

technical field [0001] The invention relates to a railway track detection method, in particular to a railway track geometric form measurement method integrating railway track internal geometric form measurement (relative measurement) and external geometric form measurement (absolute measurement). Background technique [0002] Most of the existing track detectors can only be used to measure the internal geometry of the track, which cannot meet the measurement requirements of high-speed railways for track irregularity management, and the scope of application is limited. [0003] The existing domestic similar products that can be used for high-speed railway track detection have poor measurement accuracy and are not stable enough to meet the needs of high-speed railway maintenance and management, and the scope of application is limited. Contents of the invention [0004] Aiming at the problems existing in the prior art, the present invention provides a method for detecting the...
