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. ...

AI Technical Summary

Problems solved by technology

For example, door locks are generally installed on the door, and their height has been fixed during installation. For users of different heights, it may cause difficulties in capturing face images, low recognition accuracy, and insufficient recognition speed, especially for children who are alone after school. When you go home, you need to use your face to log in conveniently and quickly

In addition, most of the current camera adjustments are manual adjustments, which are inconvenient to use and difficult to accurately adjust the camera to the desired angle. The user experience is poor, and it affects the accuracy of face recognition.
