Embodiment Construction

[0021] The specific implementation of the industry electricity demand forecasting method and system of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] refer to figure 1 , figure 1 Shown is a flowchart of an insulator defect detection method based on image processing according to an embodiment.

[0023] The insulator defect detection method based on image processing comprises the following steps:

[0024] S101, converting the image containing the insulator from the RGB color space to the HSI color space, segmenting the hue and saturation channels respectively to obtain a single-channel image of the hue component and the saturation component, and then intersecting the single-channel images obtained by the segmentation, Extract the insulator profile image;

[0025] S102, performing morphological erosion, dilation, and region growing operations on the insulator profile image with an ellipse as a structural element,...

Abstract

The invention relates to an image-processing-based insulator defect detection method and system. An image including an insulator is transformed from an RGB color space into an HIS color space, segmentation is carried out to obtain single-channel images of a tone component and a saturability component; intersection taking is carried out to extract an insulator contour, and morphological corrosion, dilation operation, regional growth, and connection region marking are carried out on an operator using an oval as a structural element in the insulator contour image; according to areas of all connection regions, a non-insulator image is rejected from the image obtained after the regional growth operation to obtain a pseudo standard binary image; and an image obtained by a closed operation is compared with the pseudo standard binary image and an insulator defect is determined based on the comparison result. The detection method is easy to implement; the operation becomes simple; and the operation speed increases.

Description

technical field [0001] The invention relates to the technical field of power equipment monitoring, in particular to an insulator defect detection method and system based on image processing. Background technique [0002] Insulators are special insulation controls that can play an important role in overhead transmission lines. Insulators on high-voltage power lines are multiple disk-shaped insulators attached to one end of the wire connection tower, usually made of glass or ceramics. Insulators are damaged due to various electromechanical stresses caused by changes in the environment and electrical load conditions, which will damage the service life and operating life of the entire line. Therefore, the insulator detection of transmission lines is a very important task for power maintenance personnel. [0003] Conventional transmission line insulator inspection methods mostly require maintenance personnel to go to the site to observe and identify whether the insulator is dama...
