Abstract

The invention provides a machine vision technology-based intelligent light bar acquisition system and a method for obtaining outer contours of railway tracks. The intelligent light bar acquisition system comprises a detection trolley, a UPS power module, an image acquisition module, a control system and a software system. The intelligent light bar acquisition system and the method can be used fordetecting conventional detection parameters of tracks; automatic acquisition and automatic control are imported, so that the working intensity can be greatly reduced; through a sliding block, a laseradjustment bracket is adjusted to slide leftwards and rightwards, so that two sides of the tracks can be directly detected; an encoder is capable of correctly detecting a movement distance of the trolley, recording a detection distance and a detection position, and controlling the movement and stop of the trolley according to the detection distance, so as to realize automatic control of the trolley; when the trolley stops, the image acquisition module acquires a target image and a background image; an image processing method adopts a difference method, so that the adaptation, to complicated environment, of the detection trolley is improved; and by adoption of ARDUINO UNO, the control system has the characteristics of being correct in control, high in speed and low in cost.

Description

technical field [0001] The invention relates to the field of track detection, in particular to an intelligent light strip acquisition system based on machine vision technology and a method for acquiring the outer contour of a railway track by using the system. Background technique [0002] The track is an important part of the railway system and the top priority of daily inspection and maintenance. Once a fault occurs, it will seriously affect the safe operation of the railway. In order to ensure the safe and reliable operation of the track, daily inspection and maintenance are very important. At present, domestic railway inspection is mainly manual inspection, which has the characteristics of low efficiency, high labor intensity and mechanical wear. The detection method based on machine vision is a new type of non-contact detection method, which has the characteristics of high precision and good visualization. The present invention mainly relates to laser detection. [0...
