Biometric identification apparatus based on fusion of iris and human face and biometric identification method using apparatus

Abstract

The present invention discloses a biometric identification apparatus based on fusion of an iris and a human face. The apparatus comprises a housing with an infrared filter plate arranged on a front panel, wherein a central processing unit, a light source unit, a human face collector located behind glass and an iris collector located behind the inside plate surface of a half-transparent and half-reflecting mirror are arranged in the housing; the iris collector is erected in the housing by a rotary holder; and the human face collector, the light source unit, the iris collector and the rotary holder are electrically connected to the central processing unit. The biometric identification apparatus based on the fusion of the iris and the human face, disclosed by the present invention, effectively solves the problems that one specific biometric feature is identified by using a present biometric identification apparatus, so that the application scope is limited, adaptive changes cannot be made according to different human races, the friendliness of iris collection is poor and the like; and meanwhile, the biometric identification apparatus can locate human eyes by using an image of the human face collector, so that the iris collector can actively adapt to a human eye position, the identification efficiency is improved, and user experience is enhanced.

Description

technical field [0001] The invention relates to a biometric identification device, in particular to a biometric identification device based on fusion of iris and human face and a biometric identification method using the device. Background technique [0002] At present, biometric technology is gradually entering the era of large-scale application. Among all biometric technologies, face and iris recognition are non-contact collection and identification, safe and clean, and avoid the spread of germs. However, most of the current biometric devices only collect and identify a specific biometric feature, which limits the application range of the device. Therefore, there is a need for a biometric identification device that combines human face and iris to make up for the respective defects of the two biometric identification devices and increase the application range of the device. [0003] In addition, the iris color varies greatly between different races. Westerners and other li...

Problems solved by technology

[0004] The first technical problem to be solved by the present invention is to provide a biometric identification device based on the fusion of iris and human face; this device effectively solves the problem that the current biometric identification device only recognizes a specific biological feature, and its application range is limited. , unable to make adaptive changes according to different races, poor iris collection friendliness and other issues; at the same time, this device can locate the position of the human eye through the image of the face collector, so that the iris collector actively adapts to the position of the human eye, improving the recognition Efficiency, enhanced user experience

[0005] The second technical problem to be solved by the present invention is to provide a biometric identification method using the biometric identification device; this method can simultaneously identify the biological characteristics of the fusion of the user's face and iris, and solve the problem of differences between different races. There are large differences in iris color among different people, and the recognition rate of iris collection is low, and the face collector is used to judge the race, and the iris collector is controlled to cooperate with different light source units to light up the lighting, which expands the applicable population of the device
