Embodiment Construction

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the embodiments of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, the connection can be used for both fixing and circuit communication.

[0026] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", ...

Abstract

The invention provides a 3D face identity authentication method and an apparatus. The method comprises the following steps of acquiring a depth image sequence and a two-dimensional image sequence containing a target face; calculating a 3D texture image of the target face; using the 3D texture image to project a two-dimensional image of the target face; extracting characteristic information in thetwo-dimensional image of the target face; and carrying out similarity comparison on the characteristic information in the two-dimensional image of the target face and characteristic information in a two-dimensional image of a reference face. In the method, 3D information and projection are combined to acquire a complete two-dimensional image of the target face so as to increase identification precision; simultaneously the method comprises steps of human eye sight detection, in vivo detection and data updating so that a user experience is improved, a false identification rate is reduced, and face changes and other problems can be solved.

Description

technical field [0001] The invention belongs to the technical field of computers, and more specifically relates to a 3D face identity authentication method and device. Background technique [0002] The human body has many unique features, such as face, fingerprints, iris, ears, etc. These features are collectively referred to as biometrics. Biometric identification is widely used in many fields such as security, home furnishing, and smart hardware. At present, relatively mature biometric identification such as fingerprint identification and iris identification have been widely used in terminals such as mobile phones and computers. For features such as faces, although related research has been very in-depth, the recognition of features such as faces is still not popular, mainly because of the limitations of existing recognition methods that lead to low recognition rates and recognition stability. These limitations mainly include being affected by the intensity of ambient lig...
