Embodiment 1

[0047] This embodiment provides a finger vein entry method, which is applied to the smart lock 1 , based on the smart lock 1 to realize the entry of finger vein templates, and the method can be specifically implemented by the main controller 11 provided on the smart lock 1 .

[0048] Please refer to figure 1 , figure 2 with image 3, the specific steps of the finger vein entry method include:

[0049] S10. Receive a finger vein entry request, and display a finger vein entry animation guide through the smart terminal.

[0050] In this embodiment, the user can send a finger vein entry request to the main controller 11 through the external smart terminal APP, and after the smart terminal APP sends the finger vein entry request, it will display a finger vein entry animation guide. The external smart terminal can be a mobile phone, Tablet or other electronic devices run APP applications such as smart lock management on the smart terminal, the main controller 11 establishes a co...

Embodiment 2

[0085] Please also see again figure 2 with image 3 , this embodiment discloses a finger vein entry system for implementing the finger vein entry method in Embodiment 1, which is set in the smart lock 1 and includes a main controller 11, a finger vein collector 13, an infrared light source 16 and The first touch sensor 14 and the second touch sensor 15 at both ends of the finger vein collection area 100 .

[0086] In this embodiment, the finger vein collection area 100 is used to place a finger. Preferably, the vein collection area 100 is provided with a groove for placing a finger and matching the shape of the finger; the first touch sensor 14 and the second touch sensor 15 are along the The direction of finger extension is set, which are respectively located at the front end and the rear end of the groove. Fingers can be inserted from the front or back of the groove, which is convenient for users to use their left or right hands to identify finger veins, increases the fle...

Embodiment 3

[0110] see Figure 8 , Embodiment 3 of the present invention provides a finger vein recording device, Figure 8 It is a schematic structural diagram of a finger vein recording device provided in Embodiment 3 of the present invention, and the finger vein recording device includes at least a memory 301 and a processor 302 .

[0111] Wherein, the memory 301 is used for storing the finger vein entry program. In some embodiments, the processor 302 may be a central processing unit (Central Processing Unit, CPU), a controller, a microcontroller, a microprocessor or other data processing chips, or other chips for running programs stored in the memory 301 or For any computing device that processes data, the running program code may be to execute a finger vein entry program and the like.

[0112] Optionally, the finger vein entry device may also include a user interface, which may include a display (Display), an input unit such as a keyboard (Keyboard), and optional user interfaces ma...

Abstract

The invention discloses a finger vein input method, which comprises the following steps of: receiving a finger vein input request, and displaying finger vein input dynamic graph guidance through an intelligent terminal; receiving a first sensing signal fed back by a first touch sensor arranged at one end of the finger vein acquisition area; receiving a second sensing signal fed back by a second touch sensor arranged at the other end of the finger vein acquisition area; when the first sensing signal and the second sensing signal are received, controlling a finger vein collector to collect a finger vein image of a current finger in a finger vein collection area and generating a characteristic value; and obtaining a corresponding finger vein input template based on the feature value generated by the finger vein image. Meanwhile, the invention further provides a finger vein input system and device and a storage medium. According to the technical scheme provided by the invention, the flexibility of deployment of the finger vein acquisition position is improved, the reliability of finger vein acquisition is improved, the problems of difficult finger vein input and high verification failure rate are avoided, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of finger vein entry, in particular to a finger vein entry method, system, device and storage medium. Background technique [0002] Finger veins use near-infrared rays to penetrate fingers to obtain vein pattern images for personal identification. It is a biometric technology with high precision and high speed. However, when performing finger vein input, a fixed finger collection position and collection direction are usually used. When using finger veins, fingers can only be inserted from one direction to realize finger vein recognition, which limits the realization of finger veins in products, such as pushing and pulling For smart locks on type doors, the finger vein recognition module is set inside the push-pull part. The structure of finger vein collection is only convenient for users to extend the fingers of one hand (left hand or right hand) from one direction for verification, so it is very important f...
