Embodiment 1

[0053] see figure 1 , is a schematic flowchart of a three-dimensional face modeling method based on multi-angle two-dimensional face pictures provided by an embodiment of the present invention, including steps S10 to S13:

[0054] S10, identifying face areas in a plurality of face images from different shooting angles, and extracting key feature information points of the face in the face areas;

[0055] Specifically, the face is first photographed at different angles within a relatively short period of time, so as to ensure that the obtained multiple face images with different shooting angles have the consistency of the face. Wherein, the plurality of obtained face images preferably at least include a face image of a front face, a face image of a left face, and a face image of a right face. After obtaining a plurality of face images of different shooting angles, the face area detection is performed on the plurality of face images, to identify the face areas in the plurality o...

Embodiment 3

[0096] An embodiment of the present invention provides a three-dimensional face modeling device based on a multi-angle two-dimensional face picture, including a processor, a memory, and a computer program stored in the memory and configured to be executed by the processor, When the processor executes the computer program, it implements the three-dimensional face modeling method based on multi-angle two-dimensional face pictures according to the first embodiment of the invention.

[0097] In the prior art, there are generally two ways to recognize a 3D face: one is to recognize by extracting local features of a 3D face, and the other is to recognize by extracting a global feature of a 3D face. Among them, the global feature refers to the feature that can effectively represent the overall contour of the face, and the global feature is very sensitive to the complex background. Different from the global feature, the local feature reflects some attributes of the face, it focuses on...

Description

technical field [0001] The present invention relates to the technical field of face recognition, in particular to a three-dimensional face modeling and recognition method and device based on multi-angle two-dimensional faces. Background technique [0002] At present, the methods used for face recognition are generally two-dimensional face recognition, but two-dimensional face recognition has the disadvantage that the recognition accuracy is not ideal because it is easily affected by makeup and lighting. In order to solve this shortcoming and improve the accuracy of face recognition, the current method is to perform face recognition through 3D face recognition technology, that is, to carry out 3D modeling of the face, and then recognize the 3D face model. . Moreover, the construction of a three-dimensional face model is the core and key of the face recognition method based on the three-dimensional face model. At present, the method for constructing a 3D face model is mainly...
