Problems solved by technology

[0003] At present, a single camera is used to identify iris feature data. A single camera can only collect a specific angle, or the camera needs to be adjusted to collect iris features from different angles to identify the target person. It is inconvenient and cumbersome to use in practice. Therefore, it is urgent to solve this problem. technical problem

Abstract

The invention provides a 3D four-dimensional iris image data identification device. Based on human body feature information in combination with eye direction information of an iris image data acquisition object, eye positions are determined, then eye iris image data of the collected object is accurately and completely acquired by an infrared depth camera to perform 3D four-dimensional reconstruction of human iris biological features, the iris image data is efficiently collected, and the sharpness and integrity of the eye iris image data are ensured to improve the efficiency of 3D reconstruction. The identification device identifies four-dimensional data by identifying target identity information without the need to compare iris data of a target person with massive data in a database one byone, so that the efficiency of comparison identification is improved, and the speed of identity identification is greatly improved; a spatial domain direct matching sky-point cloud comparison identification method is adopted for feature point fitting, and the fast fitting comparison of iris feature points is achieved to further achieve fast identity authentication identification.

Description

technical field [0001] The invention relates to the technical field of image reconstruction and recognition, in particular to a 3D four-dimensional iris image data recognition device. Background technique [0002] As a biological characteristic, iris is one of the inherent physiological or behavioral characteristics of living things, it has certain uniqueness and stability, that is, the difference between certain iris characteristics of any two creatures is relatively large, and iris characteristics generally do not occur over time This makes the iris feature very suitable for applications in scenarios such as identity authentication or identification of authentication information in collection devices. [0003] At present, a single camera is used to identify iris feature data. A single camera can only collect a specific angle, or the camera needs to be adjusted to collect iris features from different angles to identify the target person. It is inconvenient and cumbersome to...
