Description

Technical Field

[0001] The utility model relates to the technical field of vein recognition collectors, in particular to a non-contact palm vein recognition mobile collector. Background Art

[0002] A non-contact palm vein recognition mobile collector is an electronic device that works on the principle of palm vein recognition technology. It is mainly used in access control machines, attendance, meal ordering, express delivery, access management, consumption and other fields. It can obtain the image of the palm vein by irradiating the palm with near-infrared light without contact, and extract and compare features through a series of algorithms to achieve identity authentication. Palm vein recognition is a type of vein recognition and belongs to biometric technology. It is based on the strong absorption of infrared rays by the capillaries in the palm of the human body. After irradiating the palm with near-infrared light, the palm pattern shows darker lines at the subcutaneous veins. The images of the veins of the fingers, palms, and back of the hand are obtained through an infrared CCD camera, and the digital images of the veins are stored in the computer system, and the characteristic values ​​are stored.

[0003] In the continuous use of existing non-contact palm vein recognition devices, the dust accumulated on the lens over a long period of time often becomes an invisible killer of recognition accuracy, which may lead to increased recognition errors and even seriously affect the accuracy of recognition. At the same time, the display screen is also susceptible to dust invasion and is easy to leave fingerprints and various biological residues of the user, which not only affects the neat appearance of the device, but also poses a potential threat to the health of the user during the human-computer interaction process. Therefore, daily maintenance and cleaning of non-contact palm vein recognition devices is particularly important.

[0004] Therefore, there is an urgent need to provide a contactless palm vein recognition mobile collector to solve the above problems. Utility Model Content
