Automatic extraction method and device for boundary plane of aortic sinus vessels and storage medium

The invention relates to an aortic sinus tube junction plane automatic extraction method and device and a storage medium, which are applied to the technical field of image processing, and the method comprises the steps: obtaining a local mask image containing an ascending aorta and a trivalve sinus, carrying out the three-dimensional reconstruction of the local mask image to obtain a three-dimensional grid model, obtaining the feature points of the local mask image, and obtaining a three-dimensional grid model; fitting a distinguishing plane according to the midpoint coordinate and the farthest point coordinate of each tangent plane; the feature points are converted into actual space coordinate points, and the space coordinate points are classified according to the distance through a clustering method; the method comprises the following steps: selecting a maximum number of classes for distinguishing two sides of a plane, randomly selecting n points from each of the selected two classes, obtaining all points o
