Problems solved by technology
[0003] Obtaining high-quality eye images is the first step to realize iris recognition. Existing iris collection equipment is mainly based on monocular collection, and two collections are required to complete the collection of binocular iris. The operation is cumbersome and the user experience is poor.
At the same time, the existing binocular acquisition equipment has a fixed distance between the two iris collectors, which cannot adapt to changes in the interpupillary distance of different users in real time. The human-computer interaction is not good enough, and it cannot give users enough prompts. Users need to adjust repeatedly. The collection of binocular irises can only be realized in one's own position, which takes a long time, has a poor experience, and the collection accuracy is not high

Embodiment Construction
[0036] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0037] Such as Figures 1 to 4 As shown, a binocular iris registration device, the device includes a housing 1 and a central processing module 11 arranged in the housing 1; the front panel of the housing 1 is provided with a first gap, An infrared filter plate 2 is installed at the first gap; a second gap is provided on the infrared filter plate 2, and a half mirror 3 is installed at the second gap; the infrared filter plate 2 and the half mirror The mirrors 3 are center-coincidentally arranged.
[0038] A mounting frame 12 is arranged in the housing 1, and two iris collectors 4 arranged side by side are arranged on the mounting frame 12 through a displacement drive motor 5, and the two iris collectors 4 can be driven by a displacement motor. 5. Move to the left and right sides on the mounting frame 12.

The invention discloses a binocular iris registration device. The binocular iris registration device comprises a shell and a central processing module arranged in the shell. A first notch is formed in a front panel of the shell, and an infrared light filter plate is mounted at the first notch. A second notch is formed in the infrared light filter plate, and a semi-transparent semi-reflective mirror is mounted at the second notch. Two iris collectors are arranged on the inner left side and the inner right side of the shell side by side and can move in the shell transversely. The binocular iris registration device has the advantages that through cooperation of binocular ranging and distance promoting lights of the iris collectors, a user can find the right position quickly, so that collection efficiency is improved; motors are used for driving the iris collectors to adapt to pupil distances of different persons, and the iris collectors can align to double eyes of each person in real time, so that quality of collected images is improved, collection success rate is increased greatly, and user experience is improved.
Description
technical field [0001] The invention relates to an iris registration device, in particular to a binocular iris registration device and a method for collecting iris by using the device. Background technique [0002] As the most advanced biometric technology, iris biometrics is gradually becoming a leader in the field of biometrics. It has many advantages such as accuracy, non-contact, and anti-counterfeiting, leaving other biometrics far behind. [0003] Obtaining high-quality eye images is the first step to realize iris recognition. Existing iris acquisition equipment mainly uses monocular iris acquisition, and two acquisitions are required to complete binocular iris acquisition. The operation is cumbersome and the user experience is poor. At the same time, the existing binocular acquisition equipment has a fixed distance between the two iris collectors, which cannot adapt to changes in the interpupillary distance of different users in real time. The human-computer interacti...
