Embodiment 1

[0050] see Figure 1-4 The present invention provides a technical solution: a facial recognition smart lock, comprising: a smart lock body 10 , an image acquisition unit 30 , an FPGA chip 40 , a wireless communication module 80 and a PC terminal 60 .

[0051] In this embodiment, specifically, the smart lock body 10 is a structure of the prior art, and details are not described here.

[0052] In this embodiment, specifically, the FPGA chip 40 can implement image processing algorithms in hardware, and its parallel operation mode can process a large number of data streams at high speed, which is very suitable for processing image data. (Field Programmable Gate Array) is the main chip. Specifically, a soft core can be used inside the FPGA chip to implement a customizable processor CPU structure. In addition, the entire hardware circuit of the device can also add image processing hardware circuits and external auxiliary modules written according to image processing algorithms.

Embodiment 2

[0084] see Figure 5 , the present invention provides a technical solution: a working mode of a facial recognition smart lock, comprising the following steps:

[0085] S1. Whether the door lock is connected to the PC terminal and the security processing system through the wireless communication module, if the judgment result is yes, that is, the smart door lock is connected to the PC terminal 60 and the security processing system 70, and the user is operating the door lock remotely, then enter the interconnection mode ;

[0086] S2. Obtain a frame of image from the high-definition camera, and then perform noise reduction processing through the image noise reduction circuit to improve the recognizability of the image;

[0087] S3, according to the face recognition algorithm, extract the face feature value in the obtained image, and compare the value with the feature threshold value preset inside the storage module;

[0088] S4, judging whether the collected image matches the ...

Abstract

The invention discloses a facial recognition intelligent lock. The lock comprises an intelligent lock body, wherein a door lock motor and an image acquisition unit are fixedly installed in the intelligent lock body, and the image acquisition unit comprises a high-definition camera, an image noise reduction circuit, an FPGA chip, a wireless communication module and a PC terminal; according to the intelligent lock, through the installed wireless communication module, in actual use, when the same face continuously tries to unlock for five times, the FPGA chip wirelessly transmits the acquired face image to the PC terminal and the security processing system, so a user can know the face image at the first time, the security personnel can receive the face image through the security processing system, the face image can be compared with a security face database, the real identity of the suspected object can be found in the first time, tracking of the suspected object by the security personnel is facilitated, and a good anti-theft function can be achieved.

Description

technical field [0001] The invention relates to the technical field of smart locks, in particular to a facial recognition smart lock. Background technique [0002] Smart door locks refer to locks that are improved on the basis of traditional mechanical locks, and are more intelligent and simplified in terms of user safety, identification, and management. Smart door locks are the executive components of door locking in access control systems. With the development of smart home appliances, some smart locks are insecure and inconvenient because they are all contact unlocking methods, and can no longer meet people's requirements for the intelligent level of smart homes. Among related technologies, door locks that can perform face recognition have begun to Appear. [0003] However, the functions of the traditional facial recognition smart locks on the market are relatively simple, and it is very inconvenient to use. When the traditional facial recognition smart locks are used, t...
