The embodiment of the application provides a face recognition method, a face recognition device, a storage medium and an electronic device.
Referring to fig. 1, fig. 1 is a schematic view of an application scenario of a face recognition method according to an embodiment of the present application. The scene may include an electronic device 1, where the electronic device may be a smart phone, a tablet computer, a desktop computer, a notebook computer, or a palm computer, and the electronic device 1 has a storage unit and is equipped with a microprocessor to have an operation capability. The electronic device 1 may also be a device having an image capturing function, such as an entrance guard or a console. The electronic device 1 is exemplified by a mobile phone, and the mobile phone 1 may have a front camera 11, and the front camera 11 may take a picture and may take a video. The front-facing camera 11 can acquire an external image and determine face image information according to the image information, and the mobile phone 1 can perform one or more times of face recognition according to the face image information acquired by the front-facing camera 11.
The front-facing camera 11 can monitor the external image in real time in the process of acquiring the external image, that is, the front-facing camera 11 automatically detects and acquires the external image until the face image is acquired, and the face image includes face image information. It should be noted that the front-facing camera 11 may also obtain a face image after determining that face recognition is needed, for example: through the mode of voice calling, the user sends out the voice information of face recognition, and the electronic equipment 1 starts the front camera 11 to acquire the face image after receiving the voice information of face recognition sent out by the user. For another example: through a key touch mode, a user triggers a designated physical key of the electronic device 1, and the electronic device 1 receives a user trigger signal to control the camera 11 to acquire a face image.
In order to increase the unlocking security of the mobile phone 1, the following describes in detail the mobile phone 1 performs face recognition twice to realize unlocking.
In some embodiments, the mobile phone 1 may acquire and determine the first face image through the front camera 11 thereof, and the first face image has the first face image information. The information with the first face image may include feature elements of the face image, such as: eyes, nose, mouth, teeth, ears, wrinkles, etc. In some embodiments, the first facial image information may include eyes, nose, mouth, ears, etc., and may not include teeth.
After the electronic device 1 acquires the first face image information, the first face image information may be matched with first preset face image information one by one, or compared with the first preset face image information. The first preset face image information may be obtained from an image feature element library, which may be obtained through a pre-learning training. Wherein the first preset facial image information may include eyes, nose, mouth, ears, etc.
In some embodiments, if the first face image information matches the first preset face image information, the first face recognition is completed, and the second face recognition may be entered. And if the first face image information is not matched with the first preset face image information, the first face recognition is failed, the face recognition is finished, and the electronic equipment 1 is kept in a screen locking state.
In some embodiments, after the electronic device 1 completes the first face recognition, the electronic device 1 enters the second face recognition, and in the process of performing the second face recognition, the electronic device 1 acquires a second face image through the front camera 11, where the second face image may include second face image information. The second facial image information may include a plurality of facial feature elements. In some embodiments, the second facial image information is different from the first facial image information. For example, the first face image information does not include teeth, and the second face image information includes teeth.
In some embodiments, if the electronic device 1 acquires the second face image within the preset time period, the electronic device 1 may perform the second face recognition according to the acquired second face image information. Specifically, the electronic device 1 may match or compare the second face image information with second preset face image information. The second preset face image information may be obtained from an image feature element library, which may be obtained through a pre-learning training. Wherein the second preset facial image information may include eyes, nose, mouth, ears, teeth, etc.
In some embodiments, if the second face image information matches with the second preset face image information, the second face recognition is completed, and the electronic device 1 may be unlocked and enter the interface. If the second face image information is not matched with the second preset face image information, the second face recognition fails, the electronic device 1 can be controlled to be in the screen locking state, and meanwhile, a preset application of the electronic device 1, such as a camera of the electronic device 1, can be started. It can be understood that when the second face recognition fails, the camera of the electronic device 1 may be controlled to start, and the camera may be the front camera 11 or the rear camera. When the face recognition fails for the second time, other applications of the electronic device 1, such as a clock application or other preset applications, may also be started. Wherein the preset application can be set according to user habits.
It can be understood that, in the embodiment of the application, different image information is adopted for face recognition twice, so that the safety of face unlocking can be improved. Meanwhile, when the user uses the face recognition electronic device, the face of the user is often aligned with the front camera 11, but the user does not unlock the electronic device, for example: only to facilitate viewing time and to facilitate taking pictures. Therefore, the user can quickly enter the designated application, so that the user can operate the electronic device without entering the main interface of the electronic device 1, and the user experience is improved.
The details will be described below.
In the embodiment of the present application, the description will be made from the perspective of a face recognition device, which may be specifically integrated in an electronic device having an arithmetic capability, such as a tablet, a PC, a mobile phone, and the like, which has a storage unit and is equipped with a microprocessor.

In some embodiments, the face recognition method may further include: and if the frequency of carrying out secondary face recognition according to the second face image information is greater than the preset frequency, sending prompt information to prompt the distinguishing characteristics of the second preset face image information and the first preset face image information. It can be understood that, for some users, secondary face recognition unlocking is required, and if the number of times of use is small or the user forgets the features of the secondary face recognition due to other reasons, in this way, the electronic device may send a prompt message to prompt the user about which important features are to be exposed. Such as: the second preset facial image information is different from the first preset facial image information in teeth. If the user makes an error for a plurality of times or continuously for a plurality of times, for example, three times, the electronic device 1 automatically sends out a prompt message "teeth are exposed".
