Embodiment Construction
[0068] Now in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail. It should be noted that the use of step numbers (letters or numbers) in the present invention to refer to some specific method steps is only for the purpose of convenience and brevity in description, rather than limiting these method steps with letters or numbers order of. Those skilled in the art can understand that the sequence of relevant method steps should be determined by the technology itself and should not be unduly limited due to the existence of step numbers.
[0069] Such as figure 1 As shown, it is a flow chart of a method for detecting abnormally heated electrical equipment according to an embodiment of the present invention.

The invention provides an abnormal heating power equipment detection method and device and a readable storage medium, and the method comprises the following steps: carrying out the edge detection of an infrared image and a visible light image of power equipment, and obtaining an infrared edge image and a visible light edge image; performing feature point detection on the infrared edge image and the visible light edge image through a KAZE algorithm, and calculating transformation parameters of a transformation model between the infrared edge image and the visible light edge image according to matching feature point pairs obtained by matching infrared feature points and visible light feature points obtained by feature point detection; determining a non-matching region in the visible light edge image according to the transformation parameter; and determining an abnormal heating area in the visible light image according to the mask image obtained by performing threshold segmentation on theinfrared image and the non-matching area, and determining the power equipment corresponding to the abnormal heating area as abnormal heating power equipment. According to the invention, the accuracyof detecting the power equipment with abnormal heating is improved.
Description
technical field [0001] The invention relates to the technical field of abnormality detection of electric power equipment, in particular to a method, a device and a readable storage medium for detecting abnormally hot electric power equipment. Background technique [0002] The construction and maintenance of the power grid provide the impetus and guarantee for the country to enhance its comprehensive national strength and the rapid development of society. Power equipment is an important part of the power grid, and its stable operation is an important guarantee for the safe use of electricity by the people. When the power equipment is working normally, the conductor of the power equipment will generate a certain amount of heat due to the flow of current, which will make the temperature of the power equipment within a certain range. When the power equipment fails or ages, there will be abnormal heating in some areas. If this happens for a long time, it will endanger the safe o...
