Abstract

The invention provides a 3D four-dimensional hand image data recognition method and device. The method comprises the steps that the acquisition of the four-dimensional data of a hand is completed by using a camera matrix, and a four-dimensional model of the hand features is constructed according to a plurality of hand feature images, so as to realize the collection of the four-dimensional data ofthe hand features of a person; the identity information of a character is used as an identification mark to form a database comprising a plurality of pieces of four-dimensional data of the hand features; the four-dimensional data of the hand features stored in the database is searched through the identity information of a target character, and using the identity information of the target person tofind the four-dimensional data of the hand features stored in the database, and a sky-point point cloud comparison method is used for recognizing the identity of the target character. The invention also provides a 3D four-dimensional hand image data recognition device. The device comprises a hand feature information collection device, a hand feature four-dimensional data storage device, and a target character identity recognition device. The sky-point point cloud comparison method based on the spatial domain direct matching is used for the fitting of features points, thereby achieving the quick fitting comparison of the feature points of the hand, and achieving the quick authentication and recognition of an identity.

Description

technical field [0001] The present invention relates to the technical field of biological feature recognition, in particular to a 3D four-dimensional hand image data recognition method and device Background technique [0002] Biological characteristics are the inherent physiological or behavioral characteristics of living things, such as fingerprints and palm prints. 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 characteristics of one or several hands. Some cri...
