The invention relates to the technical field of medical image intelligent analysis, and provides a medical image anatomical feature automatic identification and model reconstruction method comprisingthe following steps: S1, inputting a two-dimensional image into a segmentation network for prediction, and outputting a prediction result graph corresponding to the two-dimensional image; S2, performing morphological analysis on each anatomical structure segmented from the prediction result graph, and extracting positions and contour lines of key points; S3, reading the contour line and comparingthe contour line with the shape model: when the projection contour simulated by the shape model is close to the contour line, the current shape model is the reconstruction of the real anatomical structure; S4, executing the steps S1-S3 by using at least two two-dimensional images at different visual angles, so as to reconstruct the three-dimensional model of the anatomical structure. According tothe technical scheme, the a
