Payment system with 3D face recognition and use method

Abstract

The invention provides a payment system with a 3D face recognition function and a use method. The payment system comprises a 3D face recognition module and a face recognition payment module. The 3D face recognition module is used for collecting face images of a target face and carrying out face recognition and living body recognition on the face images, and the face images comprise any one or more of an RGB face image, an infrared face image, a depth face image and a 3D face image; and the face recognition payment module is used for controlling a door lock to be unlocked when the face image is judged to be a living body face and the face image is a preset white list face, or else, giving an error prompt. The face image is collected through the 3D face, and whether the collected target face is the living body image and the preset white list face allowing unlocking or not is judged by conducting face recognition and living body recognition on the face image, so that the face recognition payment module controls the door lock to be unlocked or prompt error information, and then intelligent control of the door lock can be realized.

Description

technical field [0001] The present invention relates to a face recognition system, in particular to a payment system with 3D face recognition and a usage method. Background technique [0002] In 2014, deep learning was applied to the field of face recognition for the first time, demonstrating powerful feature learning capabilities, and increasing the recognition accuracy of LFW (Labeled Faces in the Wild) from 94% to 97%, greatly surpassing the classic face recognition method . With the development of relevant deep learning theories and the drive of large-scale face data, the accuracy rate of face recognition continues to rise, and soon breaks through the 99.8% mark, which indicates that face recognition algorithms are becoming more mature and rapidly commercially applied. landing. At present, face recognition technology is widely used in security, self-service customs clearance, medical care, education, household registration and payment and other fields. [0003] In the...

Problems solved by technology

These companies create terminal solutions according to their own needs, but do not provide public version modules, which are far from meeting the strong demand for 3D face recognition in scenarios such as door locks, access control, and UnionPay payment.

[0006] In addition, the current face recognition payment terminal uses USB to connect to the 3D camera. The stability of the USB connection is poor, and the data transmission adopts a common protocol without encryption, which is easy to be attacked by a third party and has poor security; at the same time, in the process of face recognition, depth Figure 1 Direct calculation, resulting in waste of computing resources and high power consumption of equipment
