Abstract

The present invention provides a method and device for detecting images of railway plug nails, wherein the method includes: acquiring a track image; for each acquired track image, dividing the current track image into a plurality of sub-regions, in each sub-region, adopting smooth interval self-adaptive The local ternary pattern LTP algorithm of the sub-region generates the lightness local binary pattern LBP feature histogram and the sub-region's darkness LBP feature histogram, and stitches the lightness LBP feature histogram and the darkness LBP feature histogram to obtain the sub-region's feature histogram ; Splicing the feature histograms of all sub-regions of the current track image to obtain the image features of the current track image; according to the matching degree between the image features of the current track image and the image features of the plug image, determine whether the current track image contains the plug image. The invention can automatically detect plugging images from a large number of track images, alleviate the problem of low efficiency of manual screening of plugging images, thereby improving the efficiency of plugging inspection.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for detecting images of railway plugs. Background technique [0002] The plug is a kind of electrical trackside equipment located at the rail waist. It is one of the key equipments to provide the track occupancy signal, which directly affects the transmission of railway signals and thus affects the driving safety. In actual production and life, it is necessary to inspect the plugs to ensure the safe driving of railways. [0003] The traditional inspection method for plugs is manual inspection. Because the inspection is affected by various external factors, and the inspection time is short, the manual inspection of the plugs has at least the following problems: short detection time ; Short troubleshooting time; High risk; Obvious influence by external environmental factors. In order to deal with the above problem of manual inspection of plugs on the road, the ...
