Insulator pollution flashover position identification method based on voiceprint and infrared thermal imaging

The invention discloses an insulator pollution flashover position recognition method based on voiceprint and infrared thermal imaging, and the method comprises the steps: obtaining an insulator audio in a to-be-recognized region, carrying out the voiceprint feature extraction of the insulator audio, and obtaining the voiceprint feature of an insulator to be recognized; calculating the cosine similarity between the voiceprint feature of the insulator to be recognized and the insulator pollution flashover comparison voiceprint feature, and when the cosine similarity is greater than a similarity threshold, determining that the insulator audio is an insulator pollution flashover audio, and determining that the insulator pollution flashover exists in the region; collecting infrared thermal images of the insulators in the area to obtain the temperature of the insulators and the temperatures at the two ends of the insulators, marking the insulators of which the temperature exceeds the temperatures at the two ends of
