Abstract

The purpose of the present disclosure is to provide a method and device for biopsy, electronic equipment and a storage medium, so as to solve the problem of inaccurate face recognition biopsy in the related art. The method includes: obtaining a 3D point cloud data matrix of the face of the subject to be checked through a 3D camera module, wherein the 3D point cloud data matrix includes 3D coordinate information and image parameter information of each sampling point on the face of the subject to be checked; The three-dimensional point cloud matrix is ​​input into a pre-trained space transformation model to obtain a corrected three-dimensional point cloud data matrix, wherein the space transformation model passes the coordinate distribution characteristics of the sample three-dimensional point cloud data matrix that is not in a preset pose, and The sample three-dimensional point cloud data matrix is ​​obtained by manual correction to the coordinate distribution characteristics training when it is in the preset pose; according to the corrected three-dimensional point cloud data matrix and the pre-trained living body detection model, determine the Whether the object to be checked is a living body.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular, relates to a method and device for biopsy, electronic equipment, and a storage medium. Background technique [0002] With the development of technology and the improvement of data processing efficiency, the authentication methods of legal identities are changing with each passing day. In the related art, a scheme of legal user identity verification by collecting biometric features of the person to be verified is proposed, and these biometric features may be fingerprint features, or human facial features, etc. [0003] The human face is born with other biological characteristics (fingerprint, iris, etc.) of the human body, and its uniqueness and good characteristics that are not easy to be copied provide the necessary premise for identification. Compared with other types of biometrics, face recognition is non-contact, which means that the device can obtain face...
