Image rendering apparatus and method based on an RGB camera and iris camera

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...

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 and tablets) that pursue a sense of user experience, the horrible preview image will bring users an unfriendly display experience

In addition, when the iris image is collected, the iris image collected by the iris camera is directly exposed to the display as the user's preview image, which is likely to cause a security risk of iris data leakage
