3D face recognition door refers to the millimeter 3D face model built by 3D camera for users. The features of face are detected and tracked by living body detection and face recognition algorithm, and compared with the 3D face information stored in the door lock. After face verification, the door is unlocked, and high-precision identity authentication and non-inductive unlocking are realized.

Compared with 2D face locks, 3D face locks are not easily affected by posture, expression and other factors, and are not affected by light environment. At the same time, it can prevent photos, videos, headgear and other attacks, and the recognition performance is more stable, which can realize high-precision 3D safe face recognition. 3D face recognition door lock is the most secure door lock in the current smart door lock.

The applications of 3D structured light mainly include face unlocking and secure payment, such as: 2065438+June 2008 19, OPPO's future flagship Find.

X adopts 3D structured light technology provided by Obi-Guangzhou, which can realize many scenes such as secure payment, 3D reconstruction, AR and games.

2065438+In July 2009, a number of 3D door locks using structured light technology were released at Guangzhou Construction Expo. For example, the 3D face recognition door locks released by door lock manufacturers such as Kaidishi and Zhijiaren all adopt Obi- medium light structured light technology, which can realize 3D face brushing and non-inductive unlocking.
