Track comprehensive detection platform based on machine vision

Abstract

The invention provides a track comprehensive detection platform based on machine vision. The track comprehensive detection platform based on machine vision comprises a laser perpendicularity adjustment module, a laser data collecting module, a structure light detection module, a motor module and a carrying cart, wherein the laser perpendicularity adjustment module is used for collecting laser detection data and can adjust the perpendicularity position, relative to the axis of a track, of a light knife emitted by a laser device; the laser data collecting module is used for collecting profile data, obtained by cutting the track by laser, through a camera, and can adjust the positions of the camera and a laser emitter relative to the track; the structure light detection module detects the track based on structure light and can adjust a structure light detector at multiple freedom degrees; the motor module is used for driving the structure light detection module to move along a lead screw;and the carrying cart is used for carrying all the modules to move along the track and realize track detection, and the cart is fixedly connected with a push rod. The track comprehensive detection platform based on machine vision can detect various parameters of the railway track.

Description

technical field [0001] The invention relates to a railway track detection device, in particular to a comprehensive railway track detection platform based on machine vision (laser and structured light). Background technique [0002] With the rapid development of the railway industry, the detection of the track has become the most important thing to ensure the safety of the railway. Traditional railway track detection methods can no longer meet the increasingly difficult detection tasks. It is difficult to guarantee the accuracy and efficiency of the detection of parameters such as the lowering value, wear, height difference, and gauge of the rail if manual detection is used. With the continuous improvement of detection methods and technologies, the use of optical measurement to detect rails has become an increasingly important development direction. This mainly involves laser and 3D structured light detection. [0003] The principle of the three-dimensional structured ligh...

AI Technical Summary

Problems solved by technology

But at the same time, limited by the actual detection environment, structured light detection is greatly affected by surrounding light factors, easily blocked, and the complete format of the acquisition is limited

The requirements for the detection environment are high, and the adaptability needs to be improved urgently
