Embodiment Construction

[0030] According to the attached Figure 1 ~ Figure 3 , give a preferred embodiment of the present invention, and give a detailed description, so that the functions and characteristics of the present invention can be better understood.

[0031] see figure 1 and figure 2 , a kind of unlocking method based on face recognition that the present invention implements, comprises steps:

[0032] S1: A main processor 6 controls a transmission mechanism 5 to rotate an image acquisition module 4 to an initial angular position. In this embodiment, the initial angular position is 45° upward from the horizontal direction.

[0033] S2: When a human body sensing module 3 senses that someone enters a preset sensing area, it sends a trigger signal to the main processor 6 .

[0034] S3: The main processor 6 controls the image acquisition module 4 to acquire and acquire image information according to the trigger signal.

[0035] S4: The main processor 6 judges whether the image information c...

Abstract

The invention provides a face recognition-based unlocking method and a door lock, wherein the door lock comprises a door lock body, a locking and unlocking control mechanism, a human body induction module, an image acquisition module, a transmission mechanism and a main processor, wherein the locking and unlocking control mechanism is used for controlling the door lock body to be unlocked or locked, the image acquisition module is in transmission connection with the transmission mechanism, and the locking and unlocking control mechanism, the transmission mechanism, the image acquisition module and the human body induction module are respectively in communication connection with the main processor. The face recognition-based unlocking method and door lock provided by the invention can track a human face and automatically adjust a camera to an appropriate angle, and have the advantages of large effective range, high intelligence degree, high recognition speed and high accuracy in face recognition.

Description

technical field [0001] The invention relates to the field of door locks, in particular to an unlocking method based on face recognition and a door lock. Background technique [0002] Face recognition belongs to the field of biometrics. Applying it to the field of smart door locks can change people's traditional habit of carrying keys to open the door. The opening of the door is controlled by face recognition, which greatly avoids people forgetting to bring the key to open the door. inconvenient. In addition, there is a risk of loss and theft of mechanical keys, and face recognition has higher security as identity verification. Moreover, compared with fingerprint recognition, face recognition has the advantages of non-contact and more convenience, and is easier to be accepted by users, but there are some shortcomings when face recognition is used in door locks. For example, door locks are generally installed on the door, and their height has been fixed during installation. ...
