Embodiment 1

[0041] A method for identifying abnormal wire diameters can be applied to a server to identify wires with broken strands.

[0042] A method for identifying an abnormal wire diameter provided by an embodiment of the present invention will be described in detail below in conjunction with specific implementation methods, as shown in figure 1 As shown, the specific steps are as follows:

[0043] Step 100: Preprocess the current background image (image to be recognized), and analyze and judge to obtain the background image and the partition of the target wire in the current background image. The specific operations include:

[0044] Perform a weighted average calculation on the gray value of all pixels in the standard background image (normal image without wire defects) to obtain the weighted average value of the gray value of the standard background image; at the same time, determine that the gray value in the standard background image is greater than the first gray value The ima...

Abstract

The invention discloses a wire diameter anomaly identification method and device, electronic equipment and a computer readable storage medium. The method comprises the steps of preprocessing a currentbackground image to obtain a background image of a target wire and a partition where the target wire is located; performing threshold segmentation to obtain a first image, and recording the number ofeach partition; performing connected domain filtering on the first image; performing interval device interference removal and similar object interference removal on the first image to obtain a secondimage; in the second image, taking a point of which the gray value is greater than the gray value of the black wire in the target wire as a seed point, and then performing regional growth by taking the seed point as a starting point to obtain a black connected domain of each wire; and extracting the edge of the black connected domain, performing wire edge checking calculation on the two oppositelong edges, performing linearity checking calculation judgment, and when the linearity of the two long edges is greater than a standard threshold, determining that the wire diameter is abnormal. According to the invention, targeted and efficient diameter anomaly analysis and identification processing can be carried out.

Description

technical field [0001] The invention relates to the technical field of wire identification, in particular to a method, device, electronic equipment and computer-readable storage medium for identifying abnormal wire diameters. Background technique [0002] At present, high-voltage transmission lines generally use steel-cored aluminum stranded wires, and steel-cored aluminum stranded wires are prone to partial strand breakage at low temperatures. on the wire. If it cannot be found and repaired in time, the power of the transmission line will increase sharply, and the wire may break, affecting personal safety and causing huge losses. [0003] There are many identification methods for abnormal wire diameters in the market, but they are all unified processing schemes; for example: the Chinese patent with the publication number CN108318773A and the publication date of July 24, 2018 - a method for detecting broken strands of transmission wires and system, the method for detecting...
