Embodiment 1

[0033] figure 1 It shows the implementation flow of an insulator defect detection method provided by an embodiment of the present invention, and the process is described in detail as follows:

[0034] In step S101, an image of an insulator to be detected is acquired as an image to be detected.

[0035] In this embodiment, the method of acquiring the image of the insulator to be tested can be taken by a drone, or can be acquired by a fixed camera installed near the insulator to be tested.

[0036] In step S102, the target area is obtained according to the image to be detected.

[0037] In step S103, the target area is adaptively segmented to obtain a preset number of segmented images to be detected.

[0038] In step S104, according to the block image to be detected, a comprehensive feature vector of the block image to be detected is obtained.

[0039] In step S105, it is determined whether there is a defect in the block image to be detected according to the comprehensive fea...

Abstract

The invention is applicable to the technical field of defect detection and provides a method, system and terminal device for detecting defects of an insulator. The method comprises acquiring images ofan insulator to be detected as images to be detected, acquiring a target area according to the images to be detected, carrying out self-adaptive partitioning on the target area to obtain a preset number of block images to be detected, acquiring comprehensive feature vectors of the block images to be detected according to the block images to be detected, and determining whether the block images tobe detected have defects according to the comprehensive feature vectors of the block images to be detected and a pre-stored template image model. The method, system and terminal device realize the automatic detection of the insulator and improve the detection efficiency. Through the comparison between the block images to be detected and the pre-stored template image model, the detection precisionis improved and an effective early warning for the safety hazard of the power device is realized.

Description

technical field [0001] The invention belongs to the technical field of defect detection, and in particular relates to an insulator defect detection method, system and terminal equipment. Background technique [0002] With the production and operation of my country's main 500kV high-voltage transmission lines, the monitoring and maintenance of transmission lines under the new situation has become very urgent and necessary. Among them, the defect detection of insulators, which are used to hold a conductor and insulate it from other conductors, is an important part of transmission line maintenance. During the long-term operation of insulators, due to various reasons, cracks, breaks, and contamination may occur, causing a series of equipment accidents. Therefore, it is necessary to frequently check the appearance of the porcelain bottle of the insulator. [0003] In the prior art, the voltage distribution method or image recognition method based on neural network is usually us...
