Abstract

The invention discloses a method and device for detecting brake shoe earring faults of railroad trains. The method for detecting brake shoe earring faults of railroad trains comprises the following steps of: obtaining a wheel axis coordinate of a railroad train from an image of the railroad train; obtaining a segment related to a brake shoe earring from the image of the railroad train; and constructing a brake shoe earring positioning and recognition model by adoption of a method combining deep learning and a support vector machine; and detecting the segment related to the brake shoe earring according to the brake shoe earring positioning and recognition model so as to detect brake shoe earring faults of the railroad train. According to the method and device disclosed by the invention, the technical problem that the existing method is not high in brake shoe earring fault detection correctness is solved, and the technical effect of improving the brake shoe earring fault detection correctness is realized.

Description

technical field [0001] The invention belongs to the field of computer vision and image recognition, in particular to a method and device for detecting faults of brake shoe brazing rings of railway trains. Background technique [0002] In order to ensure the safety of railway trains, it is usually necessary to carry out fault detection on railway trains. The brake shoe brazing ring is a part of the basic braking device of the train, and the fault of the brake shoe brazing ring will affect the braking of the train. [0003] In the prior art, experienced train inspectors usually inspect brake shoe brazing rings for faults, such as loss, position offset, covering, etc. However, the efficiency of manual inspection is low. In order to improve the brake shoe brazing ring In order to improve the detection efficiency of faults, an automatic identification method for truck brake shoe faults has appeared. The above method first uses image segmentation to determine the characteristic ar...
