[0061] as attached figure 1 As shown, a face relief geometric modeling method of the present invention takes a single face image as input, performs three-dimensional geometry automatic reconstruction in the grid domain, and generates a face relief model according to the thickness and mapping angle specified by the user, Including the following steps:
[0062] S1. Locate the key feature points of the face on the input single face image, and obtain the feature points of the face image;
[0063] S2. Constructing an initial 3D face based on the BFM parameterized face model;
[0064] S3. Optimizing the shape of the initial 3D face based on the Bi-Laplacian constraint point displacement method to generate a 3D face after shape optimization;
[0065] S4. Based on the connection between the light intensity of the face image and the geometric normal of the 3D face, the height field optimization is performed on the 3D face after the shape optimization, and the highly optimized 3D face...
