The present invention discloses a method for recognizing C-arm X-ray images. The method is characterized by detecting the dividing line between the thoracic and lumbar vertebrae through a U-Net model, automatically detecting the vertebrae in the spinal image using a YOLOV3 model, and identifying the thoracic and lumbar vertebrae. Finally, the C-arm X-ray image and the initial grayscale image are registered through a SIFT algorithm to identify a final C-arm X-ray recognition image. The method has the advantage of achieving good results in image recognition tasks by sorting based on region segmentation results after image detection. In order to solve the problem of lack of image field of view, an image registration method can be used since a full spinal X-ray film is provided before surgery. The feature-based image registration method is based on the matching relationship between salient points and landmarks in the image to perform registration. The method has high recognition efficiency and low error rate, and can be widely used in the field of medical image processing.
