Abstract

The invention provides a steel rail light strip distribution detection device and method, and relates to the field of rail traffic. According to the steel rail light strip distribution detection device and method, a space steel rail profile curve and distribution of a light strip on the space steel rail profile curve are obtained on the basis of a first steel rail image, a second steel rail image and light strip regions of the first and second steel rail images; the space steel rail profile curve and the distribution of the light strip on the space steel rail profile curve are mapped to a prestored standard steel rail profile curve model, and mapped light strip distribution data is extracted; in this way, the obtained light strip distribution data precision is high, so that the reliability and reference of the light strip distribution data for steel rail maintenance and fault diagnosis are quite high.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a device and method for detecting the distribution of rail light bands. Background technique [0002] Rails are the main components of railway rails. Its function is to guide the wheels of the rolling stock to move forward, bear the huge pressure of the wheels, and transmit them to the sleepers. The rails must provide the wheels with a continuous, smooth and least drag rolling surface. In the electrified railway or automatic block section, the rail can also be used as a rail circuit. The rail light band is a band-shaped area distributed along the longitudinal direction of the rail formed by the long-term dynamic contact, extrusion, friction, etc. of the wheel-rail. Due to the surface contact, the surface of the rail has a metallic luster, which forms a visual contrast with the uncontacted area. "Bright color", so it is called a light band. The light belt is actually formed by the ...
