Intelligent lock and intelligent unlocking method

Abstract

The invention relates to the technical field of intelligent locks, in particular to an intelligent lock and an intelligent unlocking method, and the intelligent lock comprises a camera unit which is used for obtaining face image information of a user, wherein the face image information comprises at least one of a face depth image, a face RGB image and a face infrared image; a control unit which isused for acquiring a facial image feature vector of the user according to the facial image information, matching the facial image feature vector with an unlocking feature vector in a preset facial image feature library, and sending an unlocking signal when the matching degree is greater than or equal to a preset first threshold value; an electronic lock unit which is used for unlocking based on the unlocking signal, wherein the unlocking feature vector is a registered user face image feature vector. By adopting the camera unit with higher recognition accuracy, the safety, intelligence and accuracy of the intelligent lock device are effectively improved.

Description

technical field [0001] The present application relates to the technical field of smart locks, in particular to a smart lock and a smart unlocking method. Background technique [0002] With the increasing development of smart electronic device technology, various smart locks are widely used in various electronic devices such as smart watches, mobile phones, safes, smart door locks and tablet computers.

[0003] However, traditional smart locks based on fingerprint recognition require fingers to touch the corresponding scanning recognition unit so that the smart recognition lock can obtain the user's fingerprint, and there are cases where the finger is injured or the fingerprint is worn and cannot be recognized, which has low security, unhygienic contact and single function. In addition, the traditional smart lock based on face recognition has the disadvantages of low security performance and being easily deceived by photos to generate false identification, and its application range is narrow
