Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for face recognition according to a first embodiment of the present invention, where the method is applied to a mobile terminal, and includes:
step S11: and in the process of carrying out face recognition on the mobile terminal, if the mobile terminal is detected to be in a target motion state, canceling the face recognition, and if not, continuing to carry out the face recognition.
The process of the mobile terminal for face recognition comprises the following stages: the method comprises a starting stage, a face collecting stage, a matching analysis stage and a result outputting stage. At any stage of the mobile terminal in the process of face recognition, the motion state of the mobile terminal can be detected in real time through devices such as an acceleration sensor, a gravity sensor or a gyroscope in the mobile terminal, for example: direction, angle, speed, etc. of the mobile terminal motion. And according to the motion state of the mobile terminal detected in real time and the target motion state set according to actual requirements, taking the target motion state as a standard for judging whether the facial recognition needs to be cancelled or not, so as to cancel the facial recognition or continue the facial recognition.
The embodiment of the invention can cancel or continue facial recognition according to different requirements of users in the process of facial recognition of the mobile terminal, not only can timely cancel facial recognition when facial recognition is triggered by mistake, but also can meet the requirement of sudden and temporary facial recognition cancellation of users, is more convenient and faster, and improves user experience.
In some preferred embodiments of the present invention, the target motion state is a turning toward a target direction, and a turning angle is greater than or equal to a target angle.
Optionally, when it is detected that the mobile terminal is turned towards a target direction, obtaining an angle at which the mobile terminal is turned towards the target direction; canceling facial recognition when the turned angle is greater than or equal to the target angle; and when the turning angle is smaller than the target angle, continuing to perform face recognition.
In the face acquisition stage, when the mobile terminal is detected to turn over towards the target direction and the turning angle is larger than or equal to the target angle, the front camera of the mobile terminal cannot detect the complete face of the user, so that the fact that the user needs to cancel face recognition and further cancel face recognition is indicated.
The target direction can be a direction forming an angle with a plane where the mobile terminal is located, or any other set direction, and the target angle can be set according to actual requirements. The mobile terminal can be turned around a target axis (for example, one edge of the mobile terminal) when turned.
For example, referring to fig. 2, the mobile terminal 21 is located right in front of the face 22 of the user, the target direction is the direction indicated by the arrow in fig. 2, the target angle is 30 °, when the mobile terminal is detected to turn around the axis in the direction indicated by the arrow, the turning angle of the mobile terminal is obtained, when the turning angle is greater than or equal to 30 °, the front camera of the mobile terminal cannot detect the complete face of the user, the face recognition is cancelled, and when the turning angle is less than 30 °, the face recognition is continued.
Optionally, the target angle is 180 °.
When the mobile terminal is turned over by 180 degrees, the face of the user faces the face opposite to the display screen of the mobile terminal, the face of the user cannot be detected by the front camera of the mobile terminal, face recognition is cancelled, and otherwise, face recognition is continued.
In the starting stage, the matching analysis stage or the result output stage, when the mobile terminal is detected to turn towards the target direction and the turning angle is larger than or equal to the target angle, the face recognition can be cancelled.
In other preferred embodiments of the present invention, the target motion state is a shake state. That is, when it is detected that the mobile terminal is shaken, the face recognition is cancelled, otherwise, the face recognition is continued.
In the face acquisition stage, when the mobile terminal is detected to be shaken, the front camera of the mobile terminal cannot clearly detect the complete face of the user, which indicates that the user needs to cancel face recognition, and further cancel face recognition. In the starting stage, the matching analysis stage or the result output stage, when the mobile terminal is detected to be shaken, the face recognition can be cancelled.
In some preferred embodiments of the present invention, before step S11, the method further comprises: and in the case that the condition that the triggering condition for triggering the mobile terminal to start the face recognition is met is detected, the face recognition is started.
Optionally, the trigger condition is that a target physical key (e.g., 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.
The target application can be a financing application and a shopping application installed on the mobile terminal, and the target function can be a login and payment function. Such as: a user transfers accounts to friends by using a mobile phone banking application, and when the fact that a transfer confirmation key is clicked is detected, facial recognition is started, so that the authority of the user can be conveniently and quickly verified. For another example: a user confirms receipt using a shopping application and initiates facial recognition when a "confirm receipt" button is detected. Of course, the target application and the target function can be specifically set according to actual requirements, and the method is more flexible and convenient.
Although the user has psychological expectation of triggering face recognition when triggering a target function of a target application, and is not easy to cause unexpected false triggering, after the face recognition is started, when the user suddenly wants to cancel the face recognition, the face recognition method in the embodiment of the invention can more conveniently cancel the face recognition, and further improves the user experience.
Optionally, the triggering condition is that when the mobile terminal is in a screen locking state, an operation for lighting a display screen of the mobile terminal is detected, and a target touch operation is not detected.
Wherein the detected operation for lighting up the display screen of the mobile terminal may be at least one of: the method comprises the following steps of carrying out wrist-lifting unlocking operation, pressing a screen locking/unlocking key, pressing a power key and carrying out touch operation of double-clicking a display screen. The wrist-lifting unlocking operation is an operation of lifting the wrist of the mobile terminal by a user, and whether the wrist-lifting unlocking operation exists or not can be judged by detecting the inclined angle of the mobile terminal.
The target touch operation may be set according to actual requirements, for example: the target touch operation may be a pressing operation of pressing a display area on the display screen, or a sliding operation of drawing a target pattern on the display screen, or a clicking operation of clicking a target key displayed on the display screen.
The target key may be a cancel key for indicating that facial recognition is not performed, or a key for triggering a target function of the target application, such as: and a pause key displayed on the screen locking interface and used for triggering the music player to pause playing music.
Referring to fig. 3, in a specific application scenario, a mobile terminal is in a screen lock state, and when an operation for lighting a display screen of the mobile terminal is detected, the display screen is lighted; when the target touch operation is detected, the screen locking state is kept, and the face recognition is not started, so that the requirement that a user only wants to light the display screen without starting the face recognition to unlock is met, and the user can conveniently check time or push messages on a screen locking interface; otherwise, facial recognition is initiated. Assuming that the time required by the mobile terminal for the face recognition process is 3s, within the 3s, if the mobile terminal is detected to turn towards the target direction, acquiring the turning angle of the mobile terminal towards the target direction; when the turning angle is larger than or equal to the target angle, the face recognition is cancelled; and when the turning angle is smaller than the target angle, continuing to perform facial recognition so as to unlock the mobile terminal.
In the first of the three common unlocking modes in the prior art, after a display screen is lightened, facial recognition is started, the mobile terminal is unlocked and enters a standby state without being left on a screen locking interface, and a user cannot use the function of the screen locking interface, so that inconvenience is brought to the user; secondly, when the mobile terminal in the screen locking state is unlocked, the face recognition is not carried out on the screen locking interface, and the face recognition is started in other modes (such as sliding upwards on a display screen), so that the operation is complicated; thirdly, when the display screen is lighted up, the face recognition is started to unlock, but the operation still stays in the screen locking interface, the real unlocking can be realized only by operating one step, and the operation is very complicated. The embodiment of the invention not only provides various ways for triggering the face recognition operation, but also cancels the face recognition after the face recognition is started, thereby meeting different requirements of users, such as: only the display screen is desired to be lit without initiating facial recognition for unlocking; lightening a display screen and unlocking the mobile terminal; after the facial recognition is started, the facial recognition needs to be cancelled, and the like, so that the operation is simple, convenient and fast.
In the embodiment of the present invention, the time required for the mobile terminal to perform the face recognition process may be set as required, for example, 3s or 5 s. The time required for the face recognition process is the time required from the start of face recognition to the end of face recognition, namely the time required for starting face recognition, and is added with the time for collecting the facial features of the user, the time for comparing the facial features with the stored facial features and the time for outputting the comparison result. In the process of the face recognition, the face recognition can be cancelled according to needs so as to meet different requirements of users.
