Problems solved by technology

[0003] The current biometric data all use flat 2D data. Taking the biometrics of the hand as an example, the 2D method is mainly used to identify the characteristics of one or several hands. Some criminals use the 2D pictures collected by the hands , imitating 2D hand features, cheating part of the recognition system, and bringing great security risks to personal information security; taking the biometric features of the head and face as an example, the application of data related to the head and face stays in simple pictures In terms of application, the head and face data can only be processed from a specific angle, and there will be some differences in the recognition process of individual facial expressions (such as: smiling or blinking), which brings certain difficulties to information recognition

Abstract

The present invention provides a method and a system for biological feature four-dimensional data identification based on shooting of visible light. The method comprises the steps of: performing collection through a camera to obtain multiple biological feature images of a living body in given time, and constructing a biological feature four-dimensional model according to the multiple biological feature images to achieve collection of the biological feature four-dimensional data of the living body; taking identity information of the living body as identification signs to form a database comprising the biological feature four-dimensional data; and employing the identity information of the living body to find the biological feature four-dimensional data stored in the database, and performingcorresponding point cloud comparison to identify the identity of the target living body. The present invention further provides a system for biological feature four-dimensional data identification based on shooting of visible light. The method and the system for biological feature four-dimensional data identification based on shooting of visible light improve the collection and identification efficiency of the biological feature information, employ the collected biological feature information to completely recover the features of the biological features on the space so as to provide infinite possibility for application such as identity identification.

Description

technical field [0001] The invention relates to the technical field of biometric feature recognition, in particular to a biometric four-dimensional 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 all use flat 2D data. Taking the biometric characteristics of the hand as an example, the 2D method is mainly used to identify the charac...
