Embodiment 1
[0047] This embodiment provides a face recognition terminal, and the face recognition terminal may be a mobile phone, an access control system, or a computer connected to monitoring.
[0048] Through the face recognition terminal, the user can identify the identity of the avatar in the target image, or judge whether the avatar is a legal person, etc.
[0049] The face recognition terminal includes an acquisition module, a generation module, a recognition module, a processing module, a comparison module, a judgment module, a projection module, a calculation module and a coverage module.
[0050] The obtaining module is used to obtain the 3D model of the avatar.
[0051] The generation module is used to obtain three-dimensional feature points on the 3D model.
[0052] The three-dimensional feature points include feature points on the ear contour, nose feature points, eye feature points, mouth feature points, head contour feature points and hairline contour feature points.

Embodiment 2
[0079] This embodiment is basically the same as Embodiment 1, the only difference is:
[0080] The target feature points are three-dimensional feature points, and the face recognition terminal further includes an execution module,
[0081] The execution module is used to connect the 3D model and the three-dimensional feature points of the target image in pairs to obtain the connection line;
[0082] The comparison module is used to compare the length ratio and angle formed by adjacent connecting lines of the 3D model with the length ratios and angles formed by corresponding adjacent connecting lines in the target image to obtain the similarity value.
[0083] see figure 2 , the face recognition method of this embodiment replaces step 104 of Embodiment 1 with:
