Problems solved by technology

[0002] Existing screen unlocking systems for mobile phones and other terminals can use 2D images for face recognition to determine the corresponding identity when performing identity verification. This method cannot distinguish between photos and real people, and 2D images carry less feature information of faces. Therefore, there is a problem of large recognition errors when unlocking the screen through face recognition for identity verification.

Abstract

The present invention discloses a screen unlocking method, apparatus and device, and a computer readable storage medium. The method comprises the steps of: employing an atomization detector under outside triggering to detect whether a lens of a depth camera device is atomized or not, if yes, starting a heating device to heat the lens, or else, employing the depth camera device to collect 3D information of a face in a corresponding area; and after the 3D information of the face in the corresponding area is collected, determining whether pre-stored 3D information has information being consistentto the collected 3D information or not, if yes, performing unlocking operation of a screen of a corresponding terminal, or else, outputting prompting information that the collected 3D information hasno unlocking authority. The face recognition precision is greatly increased when the screen is unlocked. Besides, influences of human factors and weather factor are reduced through determination of atomization, the determination accuracy is improved, and the working efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of screen unlocking, and more specifically, to a screen unlocking method, device, equipment, and computer-readable storage medium. Background technique [0002] Existing screen unlocking systems for mobile phones and other terminals can use 2D images for face recognition to determine the corresponding identity when performing identity verification. This method cannot distinguish between photos and real people, and 2D images carry less feature information of faces. Therefore, there is a problem of large recognition errors when unlocking the screen by means of face recognition for identity verification. [0003] To sum up, how to provide a technical solution for screen unlocking with high face recognition accuracy is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] The object of the present invention is to provide a screen unlocking method, device, equip...
