example 1

[0033] Example 1: Demodulate the phase information corresponding to the deformed position pixel in the structured light image, convert the phase information into height information, and obtain the three-dimensional model of the user's face corresponding to the structured light image according to the height information. Of course, it can also be combined with contour recognition technology based on The three-dimensional model of the user's face recognizes the contour of the user's face, and obtains the three-dimensional model according to the contour.

example 2

[0034] Example 2: Using relevant contour recognition technology to identify the position information of the user's face in the overall structured light image, demodulate the phase information of the pixel corresponding to the face in the structured light image, convert the phase information into height information, and build based on the height information A three-dimensional model of the user's face.

[0035] S103: Extract corresponding facial feature information from the three-dimensional model.

[0036] Among them, the facial feature information may include the length and thickness of the eyebrows; the shape of the face; the size of the eyes, whether to wear glasses, the height of the bridge of the nose, the position of the facial features, etc.

[0037] S104: Match the facial feature information with the sample feature information in the preset facial three-dimensional model library, and if the matching is successful, it is determined that the user identity verification is succes...

Abstract

The invention discloses an identity verification method and apparatus, and a terminal device. The method comprises the following steps: projecting structure light on the face of a user, and obtaining a structure light image of the face of the user; generating a three-dimensional model corresponding to the face of the user according to the structure light image; extracting corresponding facial feature information from the three-dimensional model; and matching the facial feature information with sample feature information in a preset facial three-dimensional model library, and determining that the user identity verification is successful in the case of matching success. According to the identity verification method and apparatus in the embodiment of the invention, the structure light is projected on the face of the user, the structure light image of the face of the user is obtained, the three-dimensional model corresponding to the face of the user is generated according to the structure light image, the corresponding facial feature information is extracted from the three-dimensional model, the facial feature information is matched with the sample feature information in the preset facial three-dimensional model library, and it is determined that the user identity verification is successful in the case of matching success, so that the identity verification accuracy is improved, and the identity verification mode is richer.

Description

Technical field [0001] The present invention relates to the field of information processing technology, in particular to an identity verification method, device and terminal equipment. Background technique [0002] With the rapid development of Internet technology, the use of biometrics to authenticate users has gradually penetrated into people's daily lives. Among them, biological characteristics refer to the only physiological characteristics or behaviors that can be measured or automatically identified and verified, such as fingerprints, palm shape, retina, iris, voiceprint, etc. In related technologies, two-dimensional image recognition based on facial features has emerged to implement applications such as door unlocking or mobile payment. [0003] However, in real life, the use of planar two-dimensional images for recognition has fewer features and cannot accurately describe real facial features. Therefore, the above-mentioned identity verification method takes a long time to...
