Background
The track geometry detection system is arranged on a track inspection vehicle or a high-speed comprehensive detection train and is used for detecting the geometric dimension deviation of a track, including geometric irregularity items such as track gauge, track direction, height, level, triangular pits and the like. The geometric state of the railway line is comprehensively mastered through the detection of the track, and engineering personnel are guided to carry out maintenance work in a targeted manner. The rail guide rail maintenance tool is an important tool for ensuring safe, stable and comfortable driving of a railway system and maintaining and repairing the guide rail.
The current latest track geometry detection technology adopts a laser image processing technology to measure the track gauge and the high-low displacement component, adopts an inertia datum principle to measure a track datum, and obtains the real geometric irregularity parameters of the track through the calculation of a mathematical model. The track gauge parameters are acquired by a track geometry detection system through a machine vision measurement mode by using a laser and a camera.
The guarantee of the quantity value tracing is a precondition for internationally mutually acknowledging the measurement results.

The most important technical means for realizing the quantity value tracing is calibration and verification. A set of track geometry detection system needs to be calibrated to realize the quantity value tracing.

Calibration of the gauge is to determine the relationship between the quantity provided by the gauge calibrator and the indication detected by the detection system. This information is used to determine the evaluation of the track geometry detection system.
At present, a method for verifying a track gauge includes, as shown in fig. 1, attaching a magnet gauge 4 with a certain thickness value to a steel rail, measuring a track gauge at the magnet gauge 4 by using a track gauge measuring device 5, and considering that a track gauge detecting device is accurate when the track gauge measuring device 5 detects that the track gauge value is reduced from a corresponding thickness value of an approaching magnet before the magnet gauge 4 is not attached. The existing verification method has the following defects:
1. whether a laser in the track gauge detection equipment is vertically installed with a track or not cannot be verified, and calibration content is lacked.
2. The prior art has higher requirement on the magnet gauge block 4, and has abrasion on the magnet gauge block 4 in the process of being adsorbed on a steel rail for many times and being taken down, and the measured value is less than the thickness of the magnet gauge block 4 in the next measurement, but no specific value exists.
3. The magnet gauge block is attached to a gauge point (the gauge point is a position 16mm below the top surface of the steel rail) which needs to be selected by an experienced technician.
