Problems solved by technology

However, when the invention is installed, it is easy to leave a matching gap between the installation parts, and the assembly will introduce errors, which will affect the measurement results. At the same time, the test equipment is too large to be easy to move, and the installation and debugging are complicated.

Abstract

The invention belongs to the technical field of railway safety transportation, and relates to a use method of a portable modular self-correcting rail three-dimensional detection system. When the system is in use, the system is quickly assembled on site, and a manual operator is wirelessly connected with two detection units to complete the overall initialization of equipment; a marker of a calibration rod is scanned to obtain a 3D image, the 3D image is compared with factory calibration reference 3D images on the left and right sides to judge whether the 3D image is in an error range or not, the reading of a horizontal detection sensor is further read if no fault is detected, and a three-dimensional space coordinate system of the unit is self-corrected; the overall coordinate system is corrected according to the calibration rod, a coordinate system taking the geodetic horizontal plane as a reference is established through delivery calibration information of the horizontal detection sensor, and the 3D image of a railway track is integrally scanned; feature information including a rail, a rail top surface and a rail edge is identified, and feature information including a rail distance, a rail height, a rail extension angle and a rail profile is calculated; and the detection units acquire GPS positioning information and acquire walking information of a walking encoder.

Description

Technical field: [0001] The invention belongs to the technical field of railway safety transportation, and relates to a system and method for automatic rail correction, in particular to a method for using a portable modular self-correction rail three-dimensional detection system, which can realize rapid assembly and detection. Background technique: [0002] Railway transportation is one of the main modes of transportation in our country. The performance status of the rail directly affects the safety of railway traffic. The measurement of the geometric parameters of the rail is one of the important bases for verifying the performance parameters of the rail. At present, the most commonly used detection method on railways is manual measuring tool detection, which requires manual operation of different measuring tools, and the test results are directly affected by the level of operators, which is easy to introduce manual interference. The relatively large volume of automatic t...
