Substation bird identification method and system based on video and audio identification

The invention discloses a transformer substation bird recognition method and system based on video and audio recognition, and the method comprises the steps: carrying out the key feature point detection of collected video data of birds around a transformer substation through a FAST algorithm, marking the detected key feature points through a BRIEF algorithm, and carrying out the recognition of the birds around the transformer substation through a BRIEF algorithm; the method comprises the following steps: obtaining bird video data marked with key feature points, carrying out partition processing on a bird video data picture, identifying large change areas needing to be determined again, and cutting the large change areas by utilizing a rectangular frame to serve as an independent image; mosaic data enhancement is carried out on the bird image data of the large change area cut by the rectangular frame; image data conforming to bird characteristics are screened out from the bird image data subjected to data enha
