Summary:The invention discloses a face shape distinguishing method based on a three-dimensional face model, and the method comprises the steps: (1) collecting a face image sample, carrying out the preprocessing of the face image sample, and carrying out the marking of a face shape; (2) performing three-dimensional modeling on the labeled face picture to generate a three-dimensional model file; (3) determining face key points of the two-dimensional face picture; (4) reading a three-dimensional model file, and mapping key points on the two-dimensional face image into a three-dimensional model; (5) calculating an average face length-width ratio, a lower jaw-face width ratio and a lower jaw angle corresponding to each face form according to key point positions in the three-dimensional model, and storing the average face length-width ratio, the lower jaw-face width ratio and the lower jaw angle as basic data of each face form; and (6) selecting a face image to be tested, preprocessing the face image, repeating the above s
