Background technique

With the development of mobile terminals, more and more mobile terminals support the function of facial recognition. Users only need to point their faces at the front camera of the mobile phone to identify whether the facial features are consistent with those recorded in advance. Some functions of the mobile terminal, such as: unlocking, payment, etc., are verified, and the operation is simple and the response is fast. Unlike fingerprint recognition, the process of facial recognition is non-contact. Like fingerprint recognition, there is no need to touch your finger to a fixed recognition position. Therefore, it is difficult to have a clear trigger method for facial recognition, which may easily cause false triggers or affect other functions. normal use.

For example: in the prior art, when unlocking a mobile terminal in a locked screen state, face recognition is usually started after the user lights up the display screen of the mobile terminal (or there is an operation that triggers the display screen to be turned on). However, before the face recognition function was added to the mobile terminal, the lock screen interface usually appeared when the display screen was turned on. Users could check the time, notifications, and enjoy their favorite wallpapers on the lock screen interface, and even control the playback and pause of music. . After the face recognition function is added to the mobile terminal, the face recognition will be started after the display is turned on, and the mobile terminal will be unlocked and enter the standby state without staying on the lock screen interface. At this time, the user cannot use the functions provided by the lock screen interface, such as: a user I want to pause the music, but after turning on the display screen, face recognition is activated immediately to enter the unlocked interface, so that the user cannot pause the playing music on the lock screen interface, which brings inconvenience to the user.

Therefore, how to cancel the facial recognition during the facial recognition process of the mobile terminal is a technical problem to be solved urgently at present.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Referring to FIG. 1, FIG. 1 is a schematic flowchart of a face recognition method according to Embodiment 1 of the present invention. The method is applied to a mobile terminal, including:

Step S11: During the face recognition process of the mobile terminal, if it is detected that the mobile terminal is in a moving state of the target, cancel the face recognition, otherwise, continue the face recognition.

Wherein, the process of performing facial recognition by the mobile terminal includes the following stages: a start-up stage, a face collection stage, a matching analysis stage and a result output stage. At any stage during the face recognition process of the mobile terminal, the acceleration sensor, gravity sensor or gyroscope and other devices in the mobile terminal can be used to detect the movement status of the mobile terminal in real time, such as: the direction, angle, speed, etc. of the mobile terminal movement . According to the motion status of the mobile terminal detected in real time, combined with the target motion state set according to actual needs, the target motion state is used as a criterion for judging whether to cancel facial recognition, thereby canceling facial recognition or continuing facial recognition.

The embodiment of the present invention can realize that in the process of face recognition of the mobile terminal, according to the different needs of the user, the face recognition can be canceled or continued. , Temporarily cancel the need for facial recognition, more convenient and faster, and improve user experience.

In some preferred embodiments of the present invention, the target motion state is flipping toward the target direction, and the flipping angle is greater than or equal to the target angle.

Optionally, when it is detected that the mobile terminal is flipped toward the target direction, the angle at which the mobile terminal is flipped toward the target direction is obtained; when the flipped angle is greater than or equal to the target angle, facial recognition is canceled; when When the flipped angle is smaller than the target angle, face recognition is continued.

In the face collection stage, when it is detected that the mobile terminal is flipped towards the target direction, and the flipped angle is greater than or equal to the target angle, the front camera of the mobile terminal cannot detect the complete face of the user, thus indicating that the user needs to Cancel Face ID, which in turn cancels Face ID.

Wherein, the target direction may be a direction forming an angle with the plane where the mobile terminal is located, or any other set direction, and the target angle may be set according to actual needs. When the mobile terminal is turned over, it can be turned around a target axis (for example, a side of the mobile terminal).

For example, referring to FIG. 2, the mobile terminal 21 is located directly in front of the user's face 22, the target direction is the direction shown by the arrow in FIG. 2, and the target angle is 30°. , obtain the flip angle of the mobile terminal. When the flip angle is greater than or equal to 30°, the front camera of the mobile terminal cannot detect the complete face of the user, and cancel facial recognition. When the flip angle is less than 30°, continue to perform facial recognition. identify.

Optionally, the target angle is 180°.

When it is detected that the mobile terminal is flipped 180°, at this time, the user's face is facing the side opposite to the display screen of the mobile terminal, and the front camera of the mobile terminal cannot detect the user's face, cancel facial recognition, otherwise, continue Perform facial recognition.

In the startup phase, matching analysis phase or output result phase, when it is detected that the mobile terminal is flipped towards the target direction, and the flip angle is greater than or equal to the target angle, facial recognition can also be canceled.

In other preferred embodiments of the present invention, the target motion state is a shaking state. That is to say, when it is detected that the mobile terminal is shaken, the facial recognition is canceled; otherwise, the facial recognition continues.

In the face collection stage, when it is detected that the mobile terminal is shaken, the front camera of the mobile terminal cannot clearly detect the complete face of the user, indicating that the user needs to cancel the facial recognition, and then cancel the facial recognition. In the startup stage, matching analysis stage or output result stage, when it is detected that the mobile terminal is shaken, facial recognition can also be canceled.

In some preferred embodiments of the present invention, before step S11, the method further includes: starting face recognition when it is detected that a trigger condition triggering the mobile terminal to start face recognition is met.

Optionally, the trigger condition is that a target physical key (such as a power key and/or a volume key) of the mobile terminal is pressed.

Optionally, the trigger condition is that a target function of the target application is detected to be triggered.

Wherein, the target application may be financial management and shopping applications installed on the mobile terminal, and the target function may be login and payment functions. For example: a user uses a mobile banking application to transfer money to a friend. When the "confirm transfer" button is detected to be clicked, facial recognition is activated, so that the user's authority can be verified conveniently and quickly. Another example: a user uses a shopping application to confirm receipt, and when it is detected that the "confirm receipt" button is clicked, facial recognition is activated. Of course, the target application and the target function can be specifically set according to actual needs, which is more flexible and convenient.

Although the user already has the psychological expectation of triggering facial recognition when triggering a target function of the target application, it is not easy to cause unexpected false triggers, but after starting facial recognition, when the user suddenly wants to cancel this facial recognition, the implementation of the present invention The facial recognition method in the example can cancel the facial recognition more conveniently and further improve the user experience.

Optionally, the trigger condition is that when the mobile terminal is in a screen-locked state, an operation for turning on the display screen of the mobile terminal is detected, and no target touch operation is detected.

Wherein, the detected operation for lighting up the display screen of the mobile terminal may be at least one of the following: an operation of raising the wrist to unlock, an operation of pressing the lock screen/unlock key, an operation of pressing the power key, and double-clicking the display screen touch operation. Wherein, the operation of raising the wrist to unlock is an operation in which the user holds the mobile terminal and raises the wrist, and whether there is an operation of raising the wrist to unlock can be determined by detecting the angle at which the mobile terminal is tilted.

The target touch operation can be set according to actual needs, for example: the target touch operation can be set as a press operation of pressing a display area on the display screen, or drawing a target on the display screen The sliding operation of the pattern, or the clicking operation of clicking the target button displayed on the display screen.

Wherein, the target button may be a cancel button used to indicate that facial recognition is not performed, or a button used to trigger a target function of the target application, for example: a button displayed on the lock screen interface used to trigger the music player to pause playback Pause button for music.

Please refer to FIG. 3. In a specific application scenario, a mobile terminal is in a screen-locked state. When an operation for lighting the display screen of the mobile terminal is detected, the display screen is lit; Control operation, keep the lock screen state, do not start face recognition, meet the needs of users who only want to light up the display screen without starting face recognition for unlocking, so that users can check the time or pushed messages on the lock screen interface; otherwise to activate facial recognition. Assuming that the time required for the mobile terminal to perform facial recognition is 3s, within these 3s, if it is detected that the mobile terminal is flipped to the target direction, the angle at which the mobile terminal is flipped to the target direction is obtained; when the flip When the angle of flipping is greater than or equal to the target angle, the face recognition is canceled; when the flipped angle is smaller than the target angle, face recognition is continued to unlock the mobile terminal.

Among the three common unlocking methods in the prior art, the first one is to start facial recognition after the display screen is lit, and the mobile terminal is unlocked and enters the standby state without staying on the lock screen interface, and the user cannot use the functions of the lock screen interface. Inconvenience to the user; second, when unlocking the mobile terminal in the locked screen state, face recognition is not performed on the lock screen interface, and face recognition is started by other methods (such as: sliding up on the display screen), which is cumbersome to operate ; The third way is to start facial recognition to unlock while lighting up the display screen, but it still stays on the lock screen interface, and still needs one more operation to realize the real "unlock", and the operation is also very cumbersome. However, the embodiment of the present invention not only provides a variety of ways to trigger facial recognition operations, but also cancels facial recognition after face recognition is activated, so as to meet different needs of users, such as: only want to light up the display screen without activating facial recognition Unlocking; lighting the display screen and unlocking the mobile terminal; canceling face recognition after starting face recognition, etc., the operation is simple, convenient and quick.

In the embodiment of the present invention, the time required for the facial recognition process of the mobile terminal can be set as required, for example, 3s or 5s. The time required for the facial recognition process is the time required from the start of facial recognition to the end of facial recognition, that is, the time required to start facial recognition, plus the time for collecting the user's facial features and the time for comparing with the saved facial features and the time to output the comparison result.
