Embodiment 1

[0044] This embodiment provides an identity recognition terminal, and the identity recognition terminal may be a mobile phone, an access control system, or a computer connected to monitoring.

[0045] Through the identification terminal, the user can identify the identity of the avatar in the target image, or judge whether the avatar is a legal person or not.

[0046] The identity recognition terminal includes an acquisition module, a generation module, a processing module, a comparison module, a judgment module, a projection module and a calculation module.

[0047] The acquiring module is used to acquire the 3D model of the profile of the avatar.

[0048] The generation module is used to obtain three-dimensional feature points on the 3D model.

[0049] The three-dimensional feature points include feature points on the ear outline, nose feature points, eye feature points, mouth feature points and head outline feature points.

[0050] The processing module is used to acquire...

Embodiment 2

[0072] This embodiment is basically the same as Embodiment 1, the only difference is:

[0073] The target feature points are three-dimensional feature points, and the identity recognition terminal further includes an execution module.

[0074] 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;

[0075] The length ratio and angle formed by the adjacent connecting lines of the 3D model are compared with the length ratios and angles formed by corresponding adjacent connecting lines in the target image to obtain the similarity value.

[0076] see figure 2 , the identification method of this embodiment replaces step 103 of Embodiment 1 with:

Abstract

The invention discloses an identity recognition method and terminal based on 3D imaging. The identity recognition method comprises: acquiring a 3D model of the side of a portrait; acquiring a three-dimensional feature point on the 3D model; acquiring a target feature point corresponding to the position of the three-dimensional feature point from the portrait in a target image; comparing the three-dimensional feature point with the target feature point so as to obtain the similarity value of the portrait in the target image; and determining the identity of the portrait in the target image according to the similarity value. The identity recognition method and terminal can accurately recognize the identity in the image, can recognize various types of images, and have a wide recognition range,and various identity recognition application environments.

Description

technical field [0001] The invention relates to an identification method and terminal based on 3D imaging. Background technique [0002] Face recognition is a biometric technology for identification based on human facial feature information. A series of related technologies that use a video camera or camera to collect images or video streams containing human faces, automatically detect and track human faces in the images, and then perform facial recognition on the detected faces, usually also called portrait recognition and facial recognition. [0003] The research on the face recognition system began in the 1960s. After the 1980s, it was improved with the development of computer technology and optical imaging technology, and it really entered the primary application stage in the late 1990s. Technology implementation is the main focus; the key to the success of the face recognition system is whether it has a cutting-edge core algorithm, and the recognition result has a prac...
