Problems solved by technology

The cable-stayed wire is easy to be ignored, and it is prone to abnormal phenomena such as bending and deformation when it is not stressed for a long time
It is difficult to find and time-consuming to manually check the cable-stayed wires in the key components of the catenary support device, such as unstressed and missing defects.

Embodiment Construction

[0027] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0028] Any feature disclosed in this specification, unless specifically stated, can be replaced by other alternative features that are equivalent or have similar purposes. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0029] The so-called edge refers to the collection of those pixels whose surrounding pixel gray levels have step changes or roof changes. Edges widely exist between objects and backgrounds, between objects and objects, and between primitives. The edge contains rich internal information (such as direction, step properties, shape, etc.), which can outline the target object and make it clear to the observer. It is one of the most interesting features of the image. Edge detection can be divided into two...

Abstract

The invention relates to the field of detection of an inclined pull line of a contact network support device and particularly to a method and a device of identifying a no-stress defect of the inclinedpull line. Aiming at problems existing in the prior art, the invention provides a method and a device of identifying the no-stress defect of the inclined pull line. The method comprises the steps ofobtaining part linear information of a panoramic picture through image processing such as edge detection, uninterested area elimination and linear detection algorithm; then performing reasoning and judgment on a straight line which corresponds to key suspension through transcendental knowledge to obtain a support lost, a flat cantilever, an inclined cantilever, a positioning pipe and a locator part straight line; then judging whether the inclined pull line is stressed; and furthermore, when the inclined pull line is unstressed, performing linear fitting on an area where the inclined pull lineis, extracting parameters which constitute the fitting as unstressed characteristics, determining the bending and according realizing no-stress defect identification.

Description

technical field [0001] The invention relates to the field of detection of cable-stayed wires of catenary support devices, in particular to a method and device for identifying unstressed defects of cable-stayed wires. Background technique [0002] The force-bearing part between the flat arm, the inclined arm and the positioning tube, such as figure 1 shown. The cable-stayed wire is easy to be ignored, and it is prone to abnormal phenomena such as bending and deformation when it is not stressed for a long time. It is difficult and time-consuming to manually check the hidden dangers of the cable-stayed wires in the key components of the catenary support device, such as unstressed and missing defects. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method and device for identifying unstressed defects of cable-stayed wires in view of the problems existing in the prior art. Through image processing processes such ...
