Image registration method and system for surgical navigation of femoral neck fracture

The invention relates to an image registration method and system for femoral neck fracture surgical navigation, electronic equipment and a computer readable storage medium, and belongs to the technical field of medical image registration in orthopedic surgical navigation. The method comprises the steps that before an operation, thighbone image data and an operation path planned by a doctor are obtained through CT image equipment, and a thighbone three-dimensional image with the operation path is generated; x-ray images shot by an X-ray machine at different angles are obtained in the operation, and feature points on the X-ray images are extracted; setting DRR virtual scene projection parameters according to the structure of the X-ray machine, projecting the femur three-dimensional image with the operation path to generate a plurality of DRR images, and extracting feature points on the DRR images; and based on the similarity between the feature points on the X-ray image and the feature points on the DRR image,
