Problems solved by technology

[0003] At present, most of them use a single fixed-focus camera to collect iris feature data. A single fixed-focus camera can only collect a specific angle, or the camera needs to be adjusted to collect iris features at different angles. It is inconvenient and cumbersome to use in practice, so it needs to be solved urgently. a technical problem

Abstract

The present invention provides a 3D four-dimensional data collection system and method based on a visible light camera matrix. The system comprises: a support structure, an arc bearing structure arranged on the support structure, a plurality of cameras arranged on the arc bearing structure and forming a camera matrix, and a data processing unit connected with the cameras. The cameras are configured to perform collection of iris feature information to obtain multiple iris images and transmit the multiple iris images to the data processing unit; and the data processing unit is configured to perform processing of the iris images. The collection method comprises the steps of: obtaining iris images through cameras; transmitting the iris images obtained by the cameras to a central processing device for processing and calculation; and generating iris 3D four-dimensional data of a collection object. According to the embodiment of the invention, the multi-camera control technology is employed to perform collection of the iris feature information so as to observably improve the collection efficiency of the iris feature information.

Description

technical field [0001] The invention relates to the technical field of biological feature collection, in particular to an iris 3D four-dimensional data collection system and method based on a visible light camera matrix. 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 authentication information in identification systems. [0003] At present, most of them use a single fixed-focus camera to collect iris feature data. A single fixed-focus camera can only collect a specific angle, or the camera needs to be adjusted to collect iris features at different angles. It is inconve...
