Embodiment Construction
[0006] This nonlinear three-dimensional face modeling method includes the following steps: (1) select three-dimensional samples and two-dimensional samples respectively from the existing face database as the training sample set; in the training phase, the two-dimensional training samples Set and the three-dimensional training sample set are paired according to the identity information, so that the samples in the two sets of sample sets correspond to each other according to the identity information; (2) Based on the two sets of corresponding sample sets, the respective projection matrices are trained, so that the sample projections of different dimensions (3) In the reconstruction stage, first normalize the two-dimensional samples of the two-dimensional training sample set (the scale alignment is performed according to the distance between the eyes, and the displacement alignment is performed according to the position of the tip of the nose, and normalized to a sample size of 19...
