[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 invention provides a biometric 3D data acquisition method and device based on a visible light camera. The method includes: using a camera matrix composed of multiple visible light cameras to collect biometric information to obtain multiple biometric images; processing the multiple biometric images to extract respective feature points in the multiple biometric images; The feature points in the multiple biometric images are used to generate the feature point cloud data of the biometric feature; the 3D model of the biometric feature is constructed according to the feature point cloud data to realize the collection of the 3D biometric data. The present invention adopts the camera matrix control technology to collect the biological feature information, which can significantly improve the collection efficiency of the biological feature information; and, the embodiment of the present invention utilizes the collected feature information of the biological feature in space to completely restore the spatial feature of the biological feature The various characteristics provide unlimited possibilities for the subsequent application of biometric 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...
