Problems solved by technology

[0003] The current biometric data are all 2D data on the spatial plane. Taking the biometrics of the head and face as an example, the application of data related to the head and face stays in simple image applications, that is, it can only be viewed from a specific angle. Head and face data are processed, recognized and applied in other aspects; taking the biological characteristics of the hands as an example, the 2D method is mainly used to identify the characteristics of one or several hands. 2D pictures, imitating 2D hand features, fooled some recognition systems, and brought great security risks to personal information security

Abstract

The present invention provides a biometric 3D data recognition method based on visible light photography. Multiple biometric images of organisms are obtained through camera collection, and a 3D model of biometrics is constructed based on the multiple biometric images to realize the biometric characteristics of the organism. 3D data collection; use the identity information of the organism as the identification mark to form a database including multiple pieces of biometric 3D data; use the identity information of the target organism to find the biometric 3D data stored in the database, and compare the corresponding point clouds to identify The identity of the target organism. Also provided is a biometric 3D data recognition system based on photographing with visible light. The invention improves the collection and identification efficiency of biological feature information, utilizes the collected biological feature information in space, completely restores various spatial features of biological features, and provides infinite possibilities for applications such as identification.

Description

technical field [0001] The invention relates to the technical field of biometric feature recognition, in particular to a biometric 3D data recognition method and system based on visible light photography. Background technique [0002] Biological characteristics are the inherent physiological or behavioral characteristics of living things, such as fingerprints, palm prints, irises or human faces. Biological characteristics have certain uniqueness and stability, that is, the difference between any two biological characteristics is relatively large, and biological characteristics generally do not change greatly over time, which makes biological characteristics very suitable for application In scenarios such as identity authentication or authentication information in the identification system. [0003] The current biometric data are all 2D data on the spatial plane. Taking the biometrics of the head and face as an example, the application of data related to the head and face st...
