Document Type and Number:
WIPO Patent Application WO/2022/158681
Kind Code:
A1
Abstract:
Disclosed are a door control device for controlling locking and unlocking of a door on the basis of face recognition, and a method for operating same. The present invention acquires a face image of a user through a camera mounted on a door, passes the acquired face image through a convolutional neural network to acquire an output vector, makes comparison between feature vectors of the faces of a plurality of users who are pre-specified as being permitted to enter and the output vector to identify a first feature vector having a maximum similarity to the output vector from among the feature vectors for the face images of the plurality of users, and then unlocks a locking device mounted on the door to allow the user to easily unlock the door only through face recognition when it is confirmed that an error between the first feature vector and the output vector is less than a preset reference value.
