[0047] Figure 2 This is a schematic structural diagram of a high-efficiency detection system for ultraviolet corona discharge on transmission line insulators proposed in one embodiment of the present invention.

[0048] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be the common meanings understood by people with ordinary skills in the field to which the invention belongs. The words "including" and similar words used in this article mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0050] like Figure 1 As shown, an embodiment of the present invention provides a method for efficiently detecting ultraviolet corona discharge of transmission line insulators, the method comprising steps S101 to S104, wherein:

[0051] Step S101: obtaining an ultraviolet image of a target insulator to be inspected, segmenting the ultraviolet image to be inspected according to a preset pixel gradient, and obtaining a set of regions to be inspected according to the segmentation result, wherein the set of regions to be inspected includes at least one region to be inspected;

[0052] It should be noted that the preset pixel gradient includes several ones, and its main purpose is to quickly segment the ultraviolet image. In this embodiment, the preset pixel gradient is not a single threshold, but a hierarchical parameter set composed of multiple gradient thresholds.

[0053] In addition, in the specific segmentation process, a time-series ultraviolet image of the target insulator is obtained, wherein the time-series ultraviolet image includes a plurality of ultraviolet images to be detected at consecutive moments, and each ultraviolet image to be detected is grayscaled to obtain a grayscale image corresponding to each ultraviolet image to be detected;

[0054] The preset pixel gradient includes multiple preset pixel ranges. Any pixel point in the grayscale image is selected as the starting point, and the surrounding neighborhood pixels are traversed step by step from the starting point. At least one area to be detected corresponding to each preset pixel range is obtained according to the traversal result. The expression is as follows:

[0055] R k ={O i (x i ,y i ), i = 1, 2, ..., m|T k ≤O i (x i ,y i ) <T k+1}

[0056] Among them, R k represents the area to be detected corresponding to the k-th preset pixel range, O i (x i ,y i ) represents the pixel value of the i-th pixel, x i 、y i Represent the horizontal and vertical coordinates of the i-th pixel, respectively, and m represents the area to be detected R k The total number of pixels, T k represents the lower limit value of the kth preset pixel range or the upper limit value of the k-1th preset pixel range, T k+1 Represents the upper limit of the kth preset pixel range or the lower limit of the k+1th preset pixel range. It should be noted that since pixels in the same preset pixel range may exist in discrete space, this step gradually traverses from the starting point to the surrounding neighborhood pixels, taking into account spatial consistency. The pixels in all the areas to be detected are adjacent. At the same time, there may be multiple areas to be detected within the same preset pixel range.

[0057] Furthermore, in some embodiments, the grayscale processing of the ultraviolet image to be detected is performed according to the following formula:

[0058] O i (x i ,y i )=0.299R i (x i ,y i )+0.587G i (x i ,y i )+0.114B i (x i ,y i )

[0059] Among them, R i (x i ,y i ), G i (x i ,y i ), B i (x i ,y i ) represent the R value, G value, and B value of the i-th pixel in the ultraviolet image to be detected.

[0060] Step S102: traversing all the areas to be detected in the area set to be detected to determine whether there is a discharge area in the area set to be detected;

[0061] In order to accurately identify the discharge area, in this step, the mean variance of each area to be detected is obtained, and it is determined whether the mean variance is greater than a preset variance threshold;

[0062] If the mean variance is greater than a preset variance threshold, it is determined that a discharge area exists in the area to be detected.

[0063] In some embodiments, the mean variance of each area to be detected is obtained according to the following formula:

[0064]

[0065] Among them, σ k is the mean variance of the kth region to be detected, is the average pixel value of the kth area to be detected.

[0066] Step S103: if there are discharge areas in the area to be detected, extract the first feature, the second feature, and the third feature of the discharge areas;

[0067] It should be pointed out that in this step, the first feature is the discharge area of ​​the area to be detected where the discharge area exists, the second feature is the discharge intensity of the area to be detected where the discharge area exists, and the third feature is the discharge morphology complexity of the area to be detected where the discharge area exists. The discharge morphology complexity refers to the ratio of the area to the perimeter of the discharge area.

[0068] Step S104: fusing the first feature, the second feature, and the third feature to obtain a fused feature, and evaluating the discharge degree of the corresponding discharge area according to the fused feature.

[0069] It should be noted that the fusion feature is obtained according to the following formula:

[0070] F k =α1S k +α2Q k +α3X k

[0071] Among them, F k Indicates the fusion features of the kth region to be detected where there is a discharge area, S k Indicates the discharge area of ​​the kth detection area where there is a discharge area, Q k is the discharge intensity of the kth area to be detected where there is a discharge area, X k is the discharge morphology complexity of the kth area to be detected where there is a discharge area, and α1, α2, and α3 all represent weight coefficients.

[0072] In the process of evaluating the discharge degree, first, historical discharge areas with known discharge degrees are obtained, and historical fusion features of the historical discharge areas are extracted respectively; then, the historical fusion features are labeled according to the known discharge degree, and the labeling result is a discharge degree value. The labeled historical fusion features are input into a preset initial discharge degree detection model for training to obtain a final discharge degree detection model; then, the fusion features are input into the final discharge degree detection model to obtain the discharge degree value of each area to be detected where there is a discharge area; and according to the discharge degree value, the corresponding discharge level is retrieved from the preset database. It should be noted that the preset database contains multiple discharge degree ranges and discharge levels corresponding to each discharge degree range. After obtaining the discharge degree value, it is determined in which discharge degree range the discharge degree value falls, and the corresponding discharge level can be determined.

[0073] The present invention quickly identifies the discharge area, then extracts features such as the discharge area, discharge intensity and discharge morphology complexity of the discharge area, and fuses these features to obtain fused features, which can more comprehensively reflect the characteristics of the discharge area. The fused features are then used to obtain an evaluation result, which can improve the accuracy and reliability of the discharge degree evaluation and provide a stronger guarantee for the safe and stable operation of the power grid. Specifically, first, an ultraviolet image of the target insulator to be detected is obtained and segmented according to a preset pixel gradient, and then the ultraviolet image is quickly segmented into multiple areas to be detected. Then, the set of areas to be detected is traversed to identify the areas to be detected where the discharge area exists. After the discharge area is identified, multiple features are extracted from the discharge area, and the obtained multiple features are fused. Finally, the discharge degree is obtained according to the fused features representing the comprehensive characteristics of the discharge area.

[0075] An image segmentation module 10 is configured to obtain an ultraviolet image of a target insulator to be inspected, segment the ultraviolet image according to a preset pixel gradient, and obtain a set of regions to be inspected based on the segmentation results, wherein the set of regions to be inspected includes at least one region to be inspected;
