Networking type 3D face intelligent lock

Abstract

The invention discloses a networking type 3D human face intelligent lock. The intelligent lock comprises a 3D intelligent lock server and a plurality of 3D intelligent lock clients, wherein the 3D intelligent lock server collects a 2D infrared image and a 3D depth image of a human face, extracts 2D and 3D human face feature data respectively, and sends the human face feature data to the 3D intelligent lock clients for local storage through a wired or wireless network; and the 3D intelligent lock client acquires a 2D infrared image and a 3D depth image of a human face in real time, extracts corresponding 2D and 3D human face feature data, compares the 2D and 3D human face feature data with the stored 2D and 3D human face feature data, and executes an unlocking action if the comparison succeeds. By adopting a networking scheme, one server can correspond to a plurality of clients, so a plurality of clients can be conveniently operated, and management is convenient; in addition, 2D face recognition is used for assisting 3D face recognition, the calculation amount can be reduced, calculation resources are reduced, and recognition accuracy is improved.

Description

technical field [0001] The disclosure belongs to the fields of image processing, computer vision and artificial intelligence, and specifically relates to a 3D face intelligent lock. Background technique [0002] With the development of science and technology and the emergence of the intelligent era, artificial intelligence technology has entered people's lives, and smart locks are a typical example of the application of artificial intelligence technology. Compared with traditional locks, smart locks are very convenient and fast. People are no longer limited to keys, but can easily unlock them by relying on fingerprints, face information, etc., which can be said to be very convenient and fast. Since the smart lock uses identification technology, it only responds to our human body information. Therefore, the human body information used as the "key" to unlock the lock is unique, and the security is guaranteed to a certain extent. As an entry-level product of smart home, smart ...

AI Technical Summary

Problems solved by technology

This technology has certain advantages in the field of smart home, but it also has certain disadvantages. For example, if each person enters information on the corresponding door lock to obtain known features for subsequent identification and comparison, the operation process is cumbersome and inconvenient.

In addition, 2D face recognition has disadvantages in face anti-counterfeiting, and it may be deceived by images such as photos

[0004] Existing 3D face smart locks are usually not connected to the Internet, and only recognize and unlock locally, resulting in inconvenient management, and 3D face recognition is basically point cloud data, which requires a lot of calculations due to the complexity of point cloud data resource
