Abstract

The invention provides a 3D human face quick identity authentication method and apparatus. The method comprises the following steps of S1, obtaining a depth image and a two-dimensional image comprising a current user face; S2, obtaining the depth image and the two-dimensional image of the current user face; S3, performing identity authentication primary screening on the current user face to obtaincandidate reference data sets; S4, extracting feature information of the current user face, and determining a pose orientation vector of the current user face; and S5, performing identity authentication. The functions of input, detection, identification and the like of a face identity are realized by utilizing the depth image and the two-dimensional image, and the primary screening of the reference data sets is performed in combination with the depth image and the two-dimensional image, so that the identification efficiency is improved, the influence of an external complex environment is avoided, and absolute front face of a user is not required.

Description

technical field [0001] The invention belongs to the technical field of computers, and more specifically relates to a method and device for fast identity authentication with a 3D face. Background technique [0002] In the 21st century, with the rapid development of computer science and technology, artificial intelligence, especially biometric identification technology, has made a qualitative leap. In particular, the application of personal identity authentication technology is almost ubiquitous now, and the recognition technology based on fingerprint, iris, face and other human biometrics has huge market demand in many fields, such as access control system, video surveillance, airport security check, smart Space, natural human-computer interaction, etc. Although identity authentication based on fingerprints and irises has higher accuracy and reliability than face recognition technology, due to the unique and most recognizable features of the face for each person, as well as ...
