Abstract

The invention discloses a human face unlocking method and device thereof, which are used for avoiding the influence of environmental factors when the human face is unlocked and further improving the unlocking speed. The method comprises the following steps: when the terminal equipment is in a locked state, obtaining ultrasonic echo information through an ultrasonic sensor; the echo information carries the geometrical information of the obstacles encountered by the ultrasonic wave; Face verification based on geometric information; after the face verification passes, perform an unlock operation.The technical proposal of the invention can avoid the influence of environmental factors when the human face is unlocked, thereby improving the unlocking speed.

Description

technical field [0001] The present disclosure relates to the technical field of face recognition, and in particular to a face unlocking method and device. Background technique [0002] With the popularization of smart devices and the rapid development of science and technology, greater challenges and possibilities have been brought to the practicality and convenience of smart devices. For example, for smart device unlocking modules, there are various unlocking methods, such as fingerprint unlocking, iris unlocking and face unlocking. However, for infrared face unlocking, it may be affected by environmental factors such as temperature and light. Therefore, how to avoid the influence of environmental factors when unlocking is a technical problem that needs to be solved. Contents of the invention [0003] In order to overcome the problems existing in the related technologies, the embodiments of the present disclosure provide a face unlocking method and device, which are use...
