Problems solved by technology

However, since the iris camera is a monochrome camera based on visible light or infrared rays, the collected human eye images (including iris images) are displayed in monochrome, and compared to the images collected by ordinary RGB cameras, the images presented are impressive. I feel horrible. For some mobile devices (such as smart phones a

Embodiment Construction

[0047] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0048]Before introducing the present invention, first explain the terms in the present invention. The present invention defines the camera in the prior art according to the color characteristics of the images captured by the camera. Commonly used cameras. The images it captures are RGB images. The so-called iris camera, that is, the camera used for iris recognition in the prior art, usually uses visible light or infrar...

Abstract

The invention discloses an image rendering apparatus and a method based on an RGB camera and an iris camera. The apparatus comprises a RGB camera, an iris camera, an image matching module and a display. The RGB camera is used for capturing the RGB image of a person to be identified. The iris camera is used for capturing a monochromatic image of the person to be identified. The image matching module is used for adjusting the size and the position of the RGB image according to the size and the position of the monochromatic image to generate a preview image. The display is used for displaying the preview image thereon. The invention replaces a monochromatic preview image for prompting a user to adjust the photographing position in the prior art with an RGB preview image. This, on one hand, prevents the security risks caused by the exposure of a monochromatic image with iris characteristic data to a display interface, and on the other hand, brings the user better use experience.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image presentation device and method based on an RGB camera and an iris camera. Background technique [0002] The iris is a ring-shaped part located between the black pupil and the white sclera of the eye. It generally presents a radial structure from the inside to the outside. It is composed of quite complex fibrous tissues, including many interlaced spots and filaments. , corona, stripes, crypts and other detailed features, these features are determined in a random combination before birth, and once formed remain unchanged for life. The highly unique, stable and unchangeable characteristics of the iris make the iris can be used for identification. [0003] Iris recognition is to determine the identity of people by comparing the similarity between iris image features. Among all biometric technologies including fingerprints, iris recognition is the most conv...
