Insulation blanket micro-defect identification device

Abstract

The invention discloses an insulation blanket micro-defect identification device, comprising: an image acquisition unit which is used for acquiring an image of an insulation blanket; an illumination unit which is used for providing illumination when the image acquisition unit performs image acquisition; an image processing unit which is used for firstly filtering the acquired image, then binaryzing the image, finally marking connected regions with abrupt gray level change in the image through Blob analysis, and extracting the characteristics of the regions, so as to mark the positions of defects existing in the sampled insulation blanket and the pixel sizes of the defects; and an image output unit which is used for outputting and displaying the insulation blanket image marked with the defect positions and the pixel sizes. Based on a machine vision technology, the defects of the insulation blanket are automatically detected with machine eyes instead of human eyes, and the defects which cannot be detected by the human eyes and a two-electrode method at present are overcome.

Description

technical field [0001] The invention relates to the technical field of live-line operation and maintenance of distribution networks, in particular to an image recognition-based micro-defect recognition technology for insulating blankets. Background technique [0002] With the continuous progress of my country's electric power industry and the continuous expansion of the scale of distribution network construction, the live operation of distribution network has been widely used in my country's distribution network live operation. The shielding of the charged body and the ground can effectively avoid the occurrence of ground electric shock accidents. After the insulation shielding tool arrives at the scene, it is usually placed on the canvas. First, the inspector will conduct a visual inspection of the insulation shielding tool, and then use the insulation detector to detect it. After the inspection is complete, it can be used; Working insulation masking tools, hard tools can b...

Problems solved by technology

After the insulation shielding tool arrives at the scene, it is usually placed on the canvas. First, the inspector will visually inspect the insulation shielding tool, and then use the insulation detector to test it. After the inspection is complete, it can be used; Working insulation masking tools, hard tools can be detected by insulation detectors, but soft insulating tools cannot be detected, such as insulating clothing, insulating blankets, etc., and these tools are the most commonly used insulating tools for distribution network non-stop work , is also an important tool to ensure personal safety
