Abstract

The invention provides an image detection method and device for railroad plug nails. The method comprises the following steps: acquiring railroad images; dividing each current railroad image into a plurality of sub-regions, generating a brightness local binary pattern (LBP) feature histogram and a darkness LBP feature histogram of each sub-region according to a smoothing regional self-adaptive local ternary pattern (LTP) algorithm in the sub-region, and splicing the brightness LBP feature histogram and the darkness LBP feature histogram to obtain a feature histogram of the sub-region; splicing the feature histograms of all the sub-regions of the current railroad image, so as to obtain the image feature of the current railroad image; determining whether the current railroad image contains a plug nail image or not according to the matching rate between the image feature of the current railroad image and the image feature of the plug nail image. The image detection method and device have the advantage that plug nail images can be detected from a large quantity of railroad images automatically, so as to solve the problem of low efficiency of manual plug nail image screening, that is, the plug nail inspection efficiency can be improved.

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 plug nails. Background technique [0002] The plug is a kind of electrical trackside equipment located at the waist of the rail. It is one of the key equipment to provide track occupancy signals, which directly affects the transmission of railway signals and thus affects driving safety. In actual production and life, it is necessary to conduct patrol inspections on the plug nails to ensure the safe operation of the railway. [0003] The traditional inspection method of plug nails is manual on-track inspection. Since the on-track inspection is affected by various external factors and the inspection time is short, there are at least the following problems in the manual on-track inspection of plug nails: the detection time is short ; Troubleshooting time is short; the risk is high; it is obviously affected by external environmental...
