Image recognition method and device for acupuncture needle and electronic equipment

The invention discloses an acupuncture needle image recognition method and device and electronic equipment, and belongs to the technical field of image recognition. Comprising the following steps: slicing a received to-be-detected picture, and segmenting the to-be-detected picture into a plurality of sub-pictures; inputting the plurality of sub-pictures into a Yolov5 model to extract a feature map; carrying out feature map fusion on the adjacent feature maps based on a deep and shallow feature fusion module GBFC; detecting the fused feature map and obtaining a candidate box; performing similarity matching operation on the candidate frames through a CFR (Class Feature Regularization) module; performing NMS operation de-duplication on the candidate frames after similarity matching to obtain an acupuncture needle recognition result; according to the method, aiming at the problems that the input picture is too large in size, the acupuncture needles are slender, and the acupuncture needles are densely distributed,
