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 method and a device for biological feature 3D data collection based on a visible light camera. The method comprises the steps of: employing a camera matrix formed by aplurality of visible light cameras to perform collection of biological feature information, and obtaining multiple biological feature images; processing the biological feature images, and extractingfeature points of the biological feature images; based on the extracted feature points in the biological feature images, generating feature point cloud data of the biological feature features; and constructing a 3D model of the biological features according to the feature point cloud data to achieve collection of the biological feature 3D data. Through adoption of the camera matrix control technology, the method and the device perform collection of the biological feature information to observably improve the collection efficiency of the biological feature information; and moreover, the methodand the device can employ the collected feature information of the biological features on a space to completely restore the features of the biological features on the space so as to provide infinite possibility for follow-up application of the biological feature data.

Description

technical field [0001] The invention relates to the technical field of biological feature recognition, in particular to a method and device for collecting biological feature 3D data based on a visible light camera. 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 a...
