Abstract

An automatic travelling track detector based on machine vision comprises a vehicle body, a traveling wheel contacting with the top surface of a rail is arranged on the lower side of the vehicle body,a driving motor is connected to the traveling wheel, and a guiding detection device is arranged on the lower side of the vehicle body. The car body is also provided with an ultrasonic probe wheel contacting with the rail top surface, a laser ranging sensor for detecting the rail height and the rail spacing, and a roughness meter for detecting the rail top surface roughness. The upper side of the vehicle body is provided with an industrial CCD camera for collecting image information of the rail and the surrounding environment of the rail; A control terminal is also installed on the vehicle body, and the control terminal can transmit the data collected by the pressure sensor, ultrasonic probe wheel, laser ranging sensor, roughness meter and industrial CCD camera to the remote server throughthe wireless communication module in the control terminal. By means of the guide detecting device, not only a guide function can be provided for the vehicle body, but also the smoothness of both sidesof the rail can be detected.

Description

technical field [0001] The invention relates to track detection technology, in particular to a machine vision-based automatic walking track detector. Background technique [0002] Most of the current track inspection instruments use the operation mode of manpower. With the continuous advancement of my country's railway construction, the built lines are getting longer and longer, and the amount of maintenance required is also increasing. The measurement speed of the track inspection instrument driven by manpower cannot be increased. , the labor intensity is high, and the uneven speed of human implementation affects the quality of measurement data. [0003] A self-propelled track detector (application publication number CN 107585172 A) disclosed in Chinese patent literature includes a car body, on which there are tight wheels in contact with the inner side of the rail and a walking wheel in contact with the top surface of the rail. wheel, and a driving motor is connected to th...
