1. An automatic myocardial segmentation method in two-dimensional echocardiography, comprising:
S01, calculating and extracting ridge information in two-dimensional echocardiography;
S02, extracting image skeleton data, and connecting fragmented skeleton data to obtain continuous skeleton data by using interpolation;
S03, screening the continuous skeleton data, and extracting two optimal paths from a top to a bottom based on a myocardial feature to obtain left and right myocardial skeletons;
S04, extracting a set of feature point candidates from the left and right myocardial skeletons, and selecting a pair of key matching feature points from the set of feature point candidates as anchor points based on the myocardial feature;
S05, entering anchor point data and left and right myocardial skeleton data in a mathematical model of heart chambers to fit a morphology of heart chambers and obtain an initial myocardial contour; and
S06, constructing a myocardial feature energy equation, inputting into the myocardial feature energy equation with the initial myocardial contour, and obtaining an optimal myocardial contour by iteratively minimizing the myocardial feature energy equation.
