Abstract

The invention discloses a wire and cable defect detection system. The system comprises an image acquisition module, an image processing module, a defect detection module, a defect early warning moduleand an image display module, the image acquisition module is used for acquiring surface images of a to-be-detected wire and cable in an omnibearing manner. The image processing module is used for processing the acquired wire and cable images, segmenting the processed wire and cable image and obtaining wire and cable region images, the defect detection module is used for calculating a variance ofa pixel gray value in the electric wire and cable area image, and when the variance is higher than a given defect threshold, judging that defects exist on the surface of the to-be-detected electric wire and cable, enabling a defect early warning module to carry out early warning, and displaying the electric wire and cable region images obtained by segmentation on the image display module. The system has the advantages that the image processing technology is applied to detection of the surface defects of the wires and the cables, and the detection precision and the automation level of the surface defects of the wires and the cables are improved.

Description

technical field

[0001] The invention relates to the field of defect detection, in particular to a wire and cable defect detection system. Background technique

[0002] Wires and cables play a huge role in the construction of power systems, directly affecting the stability and reliable operation of power systems. In the manufacturing process of wires and cables, it is inevitable to produce a large number of defects on the surface of wires and cables. In order to ensure the quality of wires and cables, it is necessary to detect the defects on the surface of wires and cables. The traditional detection of surface defects on wires and cables mostly uses manual inspection. However, the manual detection method has disadvantages such as strong subjectivity, high cost, easy to cause visual fatigue, and low detection efficiency and accuracy.

[0003] In view of the above defects, the present invention provides a wire and cable defect detection system, which applies image processing t...

Embodiment Construction

[0028] The present invention is further described in conjunction with the following examples.

[0029] see figure 1 , a wire and cable defect detection system in this embodiment includes an image acquisition module, an image processing module, a defect detection module, a defect early warning module, and an image display module, and the image acquisition module is used to comprehensively collect the wire and cable to be detected The surface image, the image processing module is used to denoise the collected wire and cable image, and perform target segmentation on the denoised wire and cable image to obtain the wire and cable area image in the wire and cable image, and the defect The detection module is used to calculate the variance of the pixel gray value in the image of the wire and cable area, and compare the calculated variance with a given defect threshold. When the variance is higher than the given defect threshold, it is determined that the If there is a defect on the ...
