Embodiment 1

[0035] like figure 1 As shown, it is an intelligent lock proposed in the embodiment of the present invention, which includes a battery and a circuit board powered by the battery. The circuit board is provided with a controller 11 and fingerprint identification modules connected to the controller 11 respectively. 12. Touch screen 13, LCD screen 14, Bluetooth module 15, voice module 16, card reader module 17, status indicator light 18, three-axis detection module 25, face recognition module 19, palm vein recognition module 20, debugging port 21, A door lock drive module 22 , a power management module 23 and a battery voltage detection module 24 . Specifically, the battery adopts a 5V lithium battery, the circuit board adopts a PCB circuit board, the controller 11 adopts an STM32 single-chip microcomputer, a fingerprint recognition module 12, a touch screen 13, a liquid crystal display 14, a Bluetooth module 15, a voice module 16, a card reader module 17, a status Indicator ligh...

Embodiment 2

[0037] like Figure 2 to Figure 5 As shown, in the embodiment of the present invention, a proposed method for optimizing the palm vein recognition of a smart lock applied to a smart lock includes the following steps:

[0038] Step S1, collect the palm vein pattern through the palm vein recognition module 20, and define the palm vein area frame based on the collected palm vein pattern;

[0039] Step S2, regularly generate a two-dimensional array through the scanning lines generated by the grating, and the two-dimensional array has a plurality of rectangular grating frames;

[0040] Step S3. The palm vein area frame in step S1 is overlapped with the two-dimensional array in step S2 and screened, so as to quickly discard the grating frame in the palm vein area that the palm vein has not passed through, and keep the palm vein area in the palm vein area. A raster box through which veins pass, thus forming a feature-preserving box;

[0041] Step S4, optimizing each feature retenti...

Abstract

The invention discloses an intelligent lock, which includes a battery and a circuit board powered by the battery; the invention also discloses a method for optimizing palm vein identification of an intelligent lock applied to an intelligent lock, which includes the following steps: Palm vein graphics and define the palm vein area frame; generate a two-dimensional array through grating rules and have multiple grating frames; overlap the palm vein area frame with the two-dimensional array and retain the grating frame that the palm vein passes through to form a feature preservation frame ; Optimize each feature retention frame one by one; generate a sub-two-dimensional array in the feature retention frame and divide the feature retention frame into multiple sub-feature retention frames, and form a feature refinement frame based on the optimization algorithm; refine each feature The palm vein area box of the box is returned to the palm vein recognition module. The invention has the following advantages and effects: the speed of palm vein identification can be improved, and quick response can be realized.

Description

technical field [0001] The invention relates to the technical field of intelligent locks, in particular to an intelligent lock and a palm vein identification optimization method applied to the intelligent lock. Background technique [0002] Smart locks refer to locks that are more intelligent in terms of user identification, security, and management than traditional mechanical locks; among them, smart locks are the executive components for locking doors in the access control system. [0003] For convenience and practicality, the existing smart locks generally add a palm vein recognition function to facilitate users to quickly unlock; however, the existing smart locks still have the disadvantages of slow response speed and long recognition process in the process of palm vein recognition. Contents of the invention [0004] The object of the present invention is to provide an intelligent lock and an optimization method for palm vein identification applied to the intelligent l...
