Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

At present, the electronic equipment is in a screen locking state, and optionally, a camera on the electronic equipment can acquire images in a camera visible range in real time, if the acquired images contain face information, the acquired face information can be matched with the face information which is input in advance, and if the acquired face information is matched with the face information which is input in advance, the display screen of the electronic equipment is unlocked. Cameras with face information collection function for unlocking operation function in the electronic equipment are all unidirectional at present, for example, a front camera of a straight-plate smart phone is provided with face information collection function for unlocking operation function; however, the rear camera of the straight-panel smart phone does not have the function of collecting face information for unlocking operation. If the rear camera of the straight-plate smart phone faces the face of the user, face unlocking operation cannot be performed, and the face unlocking is inconvenient.

Or, only one group of cameras with the function of acquiring face information for unlocking operation is provided in the current electronic equipment, and if the group of cameras are shielded, the face unlocking operation cannot be realized, so that the face unlocking is inconvenient.

In order to solve the above-mentioned problems, the embodiment of the application provides a face unlocking method, which can be applied to an electronic device, wherein the electronic device can include multiple groups of cameras, and at least two groups of cameras have the function of collecting face information for unlocking operation. For example, the electronic device may be: smart phones, or notebook computers, or PAD, etc.

Referring to fig. 1, a flowchart of an implementation manner of a face unlocking method according to an embodiment of the present application is shown, where the method includes:

step S101: and obtaining a trigger instruction.

Optionally, when the electronic device is detected to be in the state to be unlocked, a trigger instruction is generated, and optionally, the state to be unlocked includes: a screen locking state and a screen brightening state.

Step S102: and calling at least one group of cameras in the at least two groups of cameras based on the triggering instruction so as to acquire face information.

Optionally, the electronic device includes at least two groups of cameras with functions of acquiring face information for unlocking operation.

Alternatively, a group of cameras may include one or more cameras.

It can be understood that the invoked group of cameras can collect images within the range of the FOV (the range covered by the lens of the camera) and transmit the images to the face recognition module contained in the electronic device; the face recognition module firstly detects whether the acquired image contains a face or not, and if the acquired image contains the face, the face recognition module obtains face information from the acquired image.

Optionally, among multiple groups of cameras included in the electronic device, at least two groups of cameras are located in different areas of the electronic device, and the embodiment of the application provides, but is not limited to, the following setting positions of at least two groups of cameras.

First, electronic equipment includes first body, at least two sets of cameras set up in first body, the camera lens of first group camera in at least two sets of cameras exposes through first collection windowing, the camera lens of second group camera in at least two sets of cameras exposes through the second collection windowing, first collection windowing is located the first surface of first body, the second collection windowing is located the second surface of first body, first surface with the second surface is on the back of the body.

The surfaces of the camera lens are different in the arrangement of the windowed collection, and the directions of the incident light rays corresponding to the images which can be collected by the camera lens are different, for example, the directions of the incident light rays corresponding to the images which can be collected by the first group of camera and the second group of camera are opposite due to the fact that the first surface and the second surface are opposite.

Taking the electronic device as a straight-panel smart phone as an example, a first implementation manner is illustrated, as shown in fig. 2a to fig. 2c, which are schematic diagrams of one implementation manner of the electronic device provided in the embodiments of the present application.

As shown in fig. 2a, a first acquisition window 21 corresponding to the first group of cameras is located on a first surface 22 of the first body; as shown in fig. 2b, a second acquisition window 23 corresponding to the second group of cameras is located on the second surface 24 of the first body. As shown in fig. 2c, the first surface 22 and the second surface 24 are opposite.

Optionally, the display area of the display screen of the electronic device may be exposed through the display window of the first surface 22 of the first body (assuming that the first surface is the front side of the electronic device, the first group of cameras is the front camera, and the display area exposed by the display window of the first surface is the main display screen), and optionally, the display area of the display screen of the electronic device may be exposed through the display window of the second surface 24 (assuming that the second surface is the back side of the electronic device, the second group of cameras is the rear camera, and the display area displayed by the display window of the second surface is the auxiliary display screen); or the display area of the display screen of the electronic device is not revealed by the display windowing of the second surface 24.

In summary, since the first group of cameras and the second group of cameras all have the function of collecting face information for unlocking operation, the user can utilize the first group of cameras or the second group of cameras to perform face unlocking operation. Taking the smart phone shown in fig. 2a to 2c as an example, the face of the user can be unlocked whether facing the first surface or the second surface of the smart phone, and compared with the face of the user only facing the first surface, the face unlocking can be realized, the operation is more convenient.

Optionally, if the second surface has no auxiliary display screen, the face information collected by the second group of cameras passes verification, so that the main display screen on the first surface can be unlocked. Optionally, if the second surface has a secondary display screen, if the face information acquired by the second group of cameras passes verification, only the secondary display screen on the second surface can be unlocked; if the face information acquired by the first group of cameras passes verification, only the main display screen on the first surface can be unlocked; or if the second surface is provided with the auxiliary display screen, the auxiliary display screen of the second surface and the main display screen of the second surface can be unlocked if the face information acquired by the second group of cameras passes verification; or if the face information acquired by the first group of cameras passes the verification, the main display screen on the first surface and the auxiliary display screen on the second surface can be unlocked.

The second type of electronic equipment comprises a first body and a second body, wherein the first body is connected with the second body through a rotating shaft, so that the first body is turned over relative to the second body;

the at least two groups of cameras are arranged in the first body, the lenses of the first group of cameras in the at least two groups of cameras are exposed through a first acquisition window, the lenses of the second group of cameras in the at least two groups of cameras are exposed through a second acquisition window, the first collecting window is positioned on the first surface of the first body, the second collecting window is positioned on the second surface of the first body, and the first surface and the second surface are opposite.

Taking a smart phone as an example, the second implementation is illustrated.

Fig. 3a to 3c are schematic diagrams of another implementation of the electronic device according to the embodiment of the present application.

The first body 31 and the second body 32 are connected by a rotation shaft 33, and alternatively, the first body 31 may be turned over relative to the second body 32 based on the rotation shaft 33.

Alternatively, the first body 31 may be flipped relative to the second body 32 based on the rotation axis 33, including but not limited to: the first body 31 may be folded with respect to the second body 32 based on the rotation shaft 33 (e.g., a flip phone), or the first body 31 may be horizontally rotated with respect to the second body 32 based on the rotation shaft 33.

Alternatively, the first body 31 may be movable relative to the second body based on a guide rail, for example, a dual slider phone.

Fig. 3a and 3c illustrate an example in which the first body 31 may be bent with respect to the second body 32 based on the rotation shaft 33.

As shown in fig. 3a (a schematic view of the electronic device in a bent state), a first acquisition window 34 corresponding to the first group of cameras is located on the first surface 311 of the first body 31; as shown in fig. 3b or fig. 3c (a schematic view of the electronic device in an unfolded state), the second collection window 35 corresponding to the second group of cameras is located on the second surface 312 of the first body 31, and the first surface 311 is opposite to the second surface 312 (the first surface 311 is opposite to the second surface 312, and the first surface 22 and the second surface 24 may be opposite to each other in fig. 2 c).

Optionally, the display area of the secondary display screen of the electronic device is exposed through the display window of the first surface 311 of the first body 31, that is, the first surface 311 of the first body may be provided with the secondary display screen 3111, or the first surface 311 of the first body may not be provided with the secondary display screen.

Alternatively, the secondary display 3111 may be a borderless display or a framed display.

Optionally, the first surface 321 of the second body 32 of the electronic device has a display area 3211 (optionally, the first surface 321 of the second body 32 does not have a display area), and/or the second surface 312 of the first body has a display area 3121 (optionally, the second surface 312 of the first body does not have a display area).

Alternatively, if the first surface 321 of the second body 32 of the electronic device has the display area 3211, and the second surface 312 of the first body has the display area 3121, after the electronic device is in the unfolded state, the display area 3121 on the second surface 312 of the first body 31 and the display area 3211 of the first surface 321 of the second body 32 may be combined into one main display screen.

Optionally, the main display of the electronic device may be a flexible display, where the front projection of the main display in the unfolded state includes the second body 32, the rotating shaft, and at least part of the first body 31, where the main display can flexibly deform along with the overturning of the first body 31 relative to the second body 32. Taking fig. 3b or fig. 3c as an example, the display area 3121 on the second surface 312 of the first body 31 and the display area 3211 on the first surface 321 of the second body 32 are an integral display area, and are not display areas formed by splicing the display area 3121 and the display area 3211, that is, the display area 3121 and the display area 3211 are both partial display areas of the main display screen.

The dashed line in fig. 3b is used to indicate the position of the rotating shaft 33, and the dashed line is used to show the relative positions of the first body 31 and the second body 32. In practical applications, the electronic device is in an unfolded state, the rotating shaft 33 is not displayed, and optionally, the main display is a complete flexible display, and the rotating shaft included in the main display has no seam (as shown in fig. 3 c).

Alternatively, the main display screen may be a borderless screen (only the "bang area" where the second acquisition window 35 corresponding to the lens of the second group of cameras is located is not a display screen), or the main display screen may be a bordered screen.

Orthographic projection refers to the parallel projection line perpendicular to the projection plane, and may be as shown in fig. 3 d.

The front projection may be a front projection perpendicular to the main display screen when the electronic device shown in fig. 3b or fig. 3c is in the unfolded state.

Alternatively, the primary display screen may not be a borderless screen.

Alternatively, the first surface 311 of the first body may have control keys for operating the secondary display 3111, or may not have control keys for operating the secondary display 3111.

Alternatively, the second collecting window 35 may be located at any position on the second surface of the first body, and fig. 3c is only an example of one of the positions, and does not limit the position of the second collecting window 35.

In summary, since the first group of cameras and the second group of cameras all have the function of collecting face information for unlocking operation, the user can utilize the first group of cameras or the second group of cameras to perform face unlocking operation. Taking the smart phone shown in fig. 3a to 3c as an example, when the electronic device is in a bending state (for example, shown in fig. 3 a), face unlocking can be achieved by using the first group of cameras; when the electronic device is in an unfolded state (e.g., as shown in fig. 3b or as shown in fig. 3 c), face unlocking may be achieved using the second set of cameras. Compared with the prior art that only the second group of cameras can be used for realizing face unlocking, when the electronic equipment is in a bending state, the second group of cameras are blocked, and face unlocking cannot be realized, so that the electronic equipment is more convenient and faster.

Alternatively, if the face information collected by the first set of cameras passes the verification, the secondary display 3111 of the first surface 31 may be unlocked. Optionally, if the face information collected by the second group of cameras passes the verification, the main display screen can be unlocked; optionally, if the face information collected by the second group of cameras passes the verification, the main display screen and the auxiliary display screen 3111 may be unlocked; alternatively, if the face information collected by the first group of cameras passes the verification, the secondary display 3111 and the primary display may be unlocked.

The third type of electronic equipment comprises a first body and a second body, wherein the first body is connected with the second body through a rotating shaft, so that the first body is turned over relative to the second body; the first body comprises a first surface and a third surface, and the second body comprises a second surface and a fourth surface; the first surface is opposite to the third surface, and the second surface is opposite to the fourth surface.

The camera comprises at least two groups of cameras, wherein a first group of cameras in the at least two groups of cameras are arranged in a first body, a second group of cameras in the at least two groups of cameras are arranged in a second body, lenses of the first group of cameras are exposed through a first collecting window, lenses of the second group of cameras are exposed through a second collecting window, the first collecting window is positioned on the first surface of the first body, and the second collecting window is positioned on the second surface of the second body.

When the electronic equipment is in a bending state, the second surface is positioned on one side of the first surface, which is close to the third surface.

Taking the electronic device as a smart phone as an example, a third implementation manner is illustrated, as shown in fig. 4a to fig. 4c, which are schematic diagrams of yet another implementation manner of the electronic device according to the embodiments of the present application.

The first body 41 and the second body 42 are connected by a rotation shaft 43, and alternatively, the first body 41 may be turned over relative to the second body 42 based on the rotation shaft 43.

Alternatively, the first body 41 may be flipped relative to the second body 42 based on the rotation axis 43, including but not limited to: the first body 41 may be folded with respect to the second body 42 based on the rotation shaft 43 (e.g., a flip phone), or the first body 41 may be horizontally rotated with respect to the second body 42 based on the rotation shaft 43.

Alternatively, the first body 41 may be movable relative to the second body 42 based on a guide, for example, a dual slider phone.

Fig. 4a to 4c illustrate that the first body 41 may be bent with respect to the second body 42 based on the rotation shaft 43.

As shown in fig. 4a (a schematic view of the electronic device in a bent state), a first acquisition window 44 corresponding to the first group of cameras is located on the first surface 411 of the first body 41; as shown in fig. 4b or fig. 4c (a schematic view of the electronic device in an unfolded state), the second collection window 45 corresponding to the second group of cameras is located on the second surface 421 of the second body 42; in the bent state of the electronic device, the second surface 421 is located on a side of the first surface 411 near the third surface 412.

Optionally, the display area of the secondary display screen of the electronic device is exposed through a display window of the first surface of the first body, that is, the first surface 411 of the first body may be provided with a secondary display screen 4111 (optionally, the first surface 411 of the first body is not provided with a secondary display screen), and/or the second surface 421 of the second body 42 is provided with a display area 4211. And/or the third surface 412 of the first body is provided with a display area 4121 (optionally, the third surface 412 of the first body is not provided with a display area).

Alternatively, the secondary display 4111 may be a borderless display or a framed display.

Alternatively, if the first surface 411 of the first body has the secondary display 4111, and the second surface 421 of the second body 42 has the display area 4211, after the electronic device is in the unfolded state, the display area 4121 on the third surface 412 of the first body 41 and the display area 4211 on the second surface 421 of the second body 42 may be combined into the primary display of the electronic device.

Optionally, the main display of the electronic device may be a flexible display, where the front projection of the main display in the unfolded state includes the second body 42, the rotating shaft, and at least part of the first body 41, where the main display can flexibly deform as the first body 41 turns over relative to the second body 42. Taking fig. 4b or fig. 4c as an example, the display area 4121 on the second surface 412 of the first body 41 and the display area 4211 on the second surface 421 of the second body 42 are an integral display area, and are not display areas formed by splicing the display area 4121 and the display area 4211, that is, the display area 4121 and the display area 4211 are both partial display areas of the main display screen.

The dashed line in fig. 4b is used to indicate the position of the rotating shaft 43, and the dashed line is used to illustrate the relative positions of the first body 41 and the second body 42. In practical applications, the electronic device does not display the rotating shaft 43 when in the unfolded state, and optionally, the main display is a complete flexible display, and the main display includes no seam at the rotating shaft (as shown in fig. 4 c).

Alternatively, the main display screen may be a borderless screen (only in the "bang region" where the second acquisition window 45 corresponding to the lens of the second group of cameras is located is not a display screen).

Alternatively, the second collecting window 45 may be located at any position on the second surface of the second body, and fig. 4c is only an example of one of the positions, and does not limit the position of the second collecting window 45.

The front projection may be a front projection perpendicular to the main display screen when the electronic device shown in fig. 3b is in the unfolded state.

Alternatively, the primary display screen may not be a borderless screen.

Optionally, the first surface 411 of the first body may have a control key for operating the secondary display 4111, or may not have a control key for operating the secondary display 4111.

In summary, since the first group of cameras and the second group of cameras all have the function of collecting face information for unlocking operation, the user can utilize the first group of cameras or the second group of cameras to perform face unlocking operation. Taking the smart phone shown in fig. 4a to 4c as an example, when the electronic device is in a bending state (for example, the second group of cameras are blocked as shown in fig. 4 a), the face unlocking can be realized by using the first group of cameras; when the electronic device is in an unfolded state (e.g., as shown in fig. 4b or fig. 4c, the second set of cameras is not occluded), face unlocking may be achieved using the second set of cameras. Compared with the prior art that only the second group of cameras can be used for realizing face unlocking, when the electronic equipment is in a bending state, the second group of cameras are blocked, and face unlocking cannot be realized, so that the electronic equipment is more convenient and faster.

Alternatively, if the face information collected by the first group of cameras passes the verification, only the secondary display screen 4111 of the first surface 41 may be unlocked. Optionally, if the face information collected by the second group of cameras passes the verification, only the main display screen may be unlocked; optionally, if the face information collected by the second group of cameras passes the verification, the main display screen and the auxiliary display screen 4111 may be unlocked; optionally, if the face information collected by the first group of cameras passes the verification, the main display screen and the auxiliary display screen can be unlocked.

Fourth, the electronic device comprises a first body, a second body and a third body, wherein the first body is connected with the second body through a first rotating shaft, the third body is connected with the second body through a second rotating shaft, so that the first body overturns relative to the second body based on the first rotating shaft, and the second body overturns relative to the second body based on the second rotating shaft; the first body comprises a first surface and a second surface, the second body comprises a third surface and a fourth surface, and the third body comprises a fifth surface and a sixth surface; the first surface is opposite to the second surface, the third surface is opposite to the fourth surface, and the fifth surface is opposite to the sixth surface.

The camera comprises at least two groups of cameras, wherein a first group of cameras in the at least two groups of cameras are arranged in a first body, a second group of cameras in the at least two groups of cameras are arranged in a second body, lenses of the first group of cameras are exposed through a first collecting window, lenses of the second group of cameras are exposed through a second collecting window, the first collecting window is positioned on the first surface of the first body, and the second collecting window is positioned on the third surface of the second body.

Optionally, the display area of the secondary display screen of the electronic device may be exposed by a display window of the first surface of the first body, that is, the first surface 511 of the first body 51 may be provided with the secondary display screen 5111 (optionally, the first surface 511 of the first body 51 is not provided with the secondary display screen), and/or the third surface 521 of the second body 52 may be provided with the display area 5211, and/or the second surface 512 of the first body 51 may be provided with the display area (optionally, the second surface 512 of the first body is not provided with the display area, optionally, the operation key with the operation display area 5211), and/or the sixth surface 532 of the third body 53 may be provided with the display area (optionally, the sixth surface 532 of the third body 53 is not provided with the display area, optionally, the operation key with the operation display area 5211).

Alternatively, the secondary display 5111 may be a borderless display or a framed display.

Optionally, the fifth surface 531 of the third body 53 has a display area, or the fifth surface 531 of the third body 53 does not have a display area (optionally, has operation keys for operating the display 5111).

Alternatively, if the second surface 512 of the first body 51 has a display area, the sixth surface 532 of the third body 53 has a display area, and the third surface of the second body 52 has a display area, then the display area of the second surface 512 of the first body 51, the display area of the sixth surface 532 of the third body 53, and the display area of the third surface of the second body 52 may constitute a main display screen of the electronic device.

Optionally, the main display of the electronic device may be a flexible display, and orthographic projection of the main display in the unfolded state includes: the second body, the first shaft, the second shaft, at least part of the first body, and at least part of the third body. The main display screen can flexibly deform along with the overturning of the first body relative to the second body, and can flexibly deform along with the overturning of the third body relative to the second body. Taking fig. 5b or fig. 5c as an example, the display area of the second surface 512 of the first body 51, the display area of the sixth surface 532 of the third body 53, and the display area of the third surface of the second body 52 are all the whole display area, and are not the display areas formed by stitching three display areas, that is, the display area of the second surface 512 of the first body 51, the display area of the sixth surface 532 of the third body 53, and the display area of the third surface of the second body 52 are all part of the display area of the main display screen.

The dashed lines in fig. 5b are used to indicate the positions of the first rotating shaft and the second rotating shaft, and the dashed lines are used to show the relative positions of the first body, the second body and the third body. In practical application, when the electronic device is in an unfolded state, the first rotating shaft and the second rotating shaft are not displayed in the main display screen, and optionally, the main display screen is a complete flexible display screen, and the rotating shaft included in the main display screen is seamless (as shown in fig. 5 c).

Alternatively, the main display screen may be a borderless screen (only in the "bang region" where the second acquisition window corresponding to the lens of the second group of cameras is not a display screen).

Alternatively, the primary display screen may not be a borderless screen.

Alternatively, the second collecting window 57 may be located at any position on the second surface of the second body, and fig. 5c is only an example of one position, and does not limit the position of the second collecting window 57.

In summary, since the first group of cameras and the second group of cameras all have the function of collecting face information for unlocking operation, the user can utilize the first group of cameras or the second group of cameras to perform face unlocking operation. Taking the smart phone shown in fig. 5a to 5c as an example, when the electronic device is in a bending state (for example, the second group of cameras are blocked as shown in fig. 5 a), face unlocking can be realized by using the first group of cameras; when the electronic device is in an unfolded state (e.g., as shown in fig. 5b or 5c, the second set of cameras is not occluded), face unlocking may be achieved using the second set of cameras. Compared with the prior art that only the second group of cameras can be used for realizing face unlocking, when the electronic equipment is in a bending state, the second group of cameras are blocked, and face unlocking cannot be realized, so that the electronic equipment is more convenient and faster.

Optionally, the second set of cameras may be disposed in the third body, and the second acquisition window is located on the sixth surface. When the electronic equipment is in a bending state, the sixth surface is positioned on one side of the third surface far away from the fourth surface.

Optionally, if the face information collected by the first group of cameras passes verification, only the secondary display screen may be unlocked; optionally, if the face information collected by the second group of cameras passes the verification, only the main display screen may be unlocked; optionally, if the face information collected by the second group of cameras passes verification, the main display screen and the auxiliary display screen can be unlocked; optionally, if the face information collected by the first group of cameras passes the verification, the main display screen and the auxiliary display screen may be unlocked.

The four ways described above are merely examples of embodiments of the electronic device, and do not limit the structure of the electronic device.

Step S103: and executing unlocking operation based on the acquired face information.

Optionally, based on the collected face information, performing the unlocking operation includes:

matching the acquired face information with a face model input in advance, and unlocking the screen if the acquired face information is matched with the face model; if the face information is not matched, the face information acquired at the time is ignored, or the face information is acquired again.

The face unlocking method provided by the embodiment of the application obtains the triggering instruction; invoking at least one group of cameras in at least two groups of cameras based on the triggering instruction so as to acquire face information; and executing unlocking operation based on the acquired face information. Because at least two groups of cameras in the plurality of groups of cameras included in the electronic equipment have the function of acquiring face information for unlocking operation, any one group of cameras or a plurality of groups of cameras in the at least two groups of cameras can be called to acquire the face information when the face is unlocked; in the embodiment of the application, if one group of cameras are blocked, a group of non-blocked cameras can be utilized; if the face is only in the range covered by any group of cameras, the face does not need to be moved to the range covered by a certain group of cameras, and the method is more convenient.

In an alternative embodiment, invoking at least one of the at least two sets of cameras includes: and calling a target group camera in the at least two groups of cameras based on the equipment form of the electronic equipment with the at least two groups of cameras.

Optionally, the target set of cameras includes one or more sets of cameras.

Alternatively, the device modality of the electronic device may include, but is not limited to: the pose location of the electronic device, and/or the physical form of the electronic device.

Alternatively, the gesture position of the electronic device may be derived from a gyroscope, and/or an accelerometer, and/or a compass in the electronic device.

Optionally, the gesture position of the electronic device may include: pitch angle and/or rotation angle of the electronic device.

Taking an electronic device as a smart phone as an example, alternatively, a coordinate system as shown in fig. 6 may be established.

Optionally, the physical form of the electronic device includes: the electronic device is in an unfolded state (e.g., the state of the electronic device shown in fig. 3b, or fig. 4b, or fig. 5 b), or the electronic device is in a folded state (e.g., the state of the electronic device shown in fig. 3a, or fig. 4a, or fig. 5 b).

The above-mentioned "invoking the target group camera of the at least two groups of cameras" implementation manner based on the device configuration of the electronic device having the at least two groups of cameras is various, and the embodiments of the present application provide, but are not limited to, the following.

First, based on the gesture position of the electronic device, invoking a target group camera of the at least two groups of cameras.

Alternatively, if the electronic device is an electronic device that cannot be bent, such as a straight-panel smart phone as shown in fig. 2a, the first set of cameras on the first surface 22 is invoked if the gesture position of the electronic device indicates the positive direction of the first surface 12 of the electronic device toward the XOY plane.

It will be appreciated that when the user is holding the electronic device, if the gesture position of the electronic device indicates the positive direction of the first surface 12 of the electronic device facing the XOY plane, then the face of the user faces the first surface of the electronic device, and the face of the user may be within the coverage of the lens of the first group of cameras, so that the first group of cameras is invoked.

Alternatively, if the pose position of the electronic device characterizes a negative direction of the first surface 22 of the electronic device toward the XOY plane, a second set of cameras on the second surface 24 is invoked.

It will be appreciated that when the user is holding the electronic device, if the gesture position of the electronic device indicates the negative direction of the first surface 12 of the electronic device facing the XOY plane, then the face of the user faces the second surface of the electronic device, and the face of the user may be within the coverage of the lens of the second set of cameras, so the second set of cameras is invoked.

It will be appreciated that the user may be looking down at the electronic device, and if the pose position of the electronic device characterizes the negative direction of the first surface 12 of the electronic device towards the XOY plane, then the face of the user is oriented towards the first surface of the electronic device, and the face of the user may be within the coverage of the lens of the first set of cameras; if the gesture position of the electronic device characterizes the positive direction of the first surface 12 of the electronic device towards the XOY plane, then the face of the user is towards the second surface of the electronic device, and the face of the user may be within the coverage of the lenses of the second set of cameras, to avoid this, optionally the first set of cameras and the second set of cameras may be invoked simultaneously.

And secondly, calling a target group camera in the at least two groups of cameras based on the physical form of the electronic equipment.

If the electronic equipment is in a first equipment form, calling a first group of cameras; the first equipment is in a bending state, and the first group of cameras are cameras with the electronic equipment in the bending state and are not shielded to collect and open windows.

Taking fig. 3a, fig. 4a, or fig. 5a as an example, when the electronic device is in a bending state, the first acquisition windows of the first group of cameras are not blocked, and the second acquisition windows of the second group of cameras are blocked.

It can be appreciated that, because the second of second group camera gathers the windowing and is sheltered from, if the user needs to utilize the second group camera to realize face unblock, still need to become electronic equipment from bending state to expansion state, lead to inconvenient, in this application embodiment, can be in the bending state at electronic equipment, utilize not sheltered from the first group camera that gathers the windowing and realize face unblock, it is more convenient.

If the electronic equipment is in a second equipment form, a second group of cameras are called, wherein the second equipment form is an unfolding state, and the second group of cameras are cameras with the electronic equipment in the bending state and shielded, acquired and windowed; or if the electronic device is in the second device form, simultaneously calling the second group of cameras and the first group of cameras.

Taking fig. 3b or fig. 3c or fig. 4b or fig. 4c or fig. 5b or fig. 5c as an example, when the electronic device is in the unfolded state, the first acquisition windows of the first group of cameras are not blocked, and the second acquisition windows of the second group of cameras are not blocked.

It can be understood that if the electronic device is in the unfolded state, the user needs to use the main display screen generally, and at this time, the probability that the face of the user faces the second group of cameras is very high, and at this time, the second acquisition window of the second group of cameras is not blocked, so that the second group of cameras is called.

It will be appreciated that if the electronic device is in the unfolded state, it is also possible that the user is facing the first set of cameras, so the first set of cameras and the second set of cameras may be invoked simultaneously.

It can be understood that the electronic device can enter different permission modes after the collected face information passes verification under different device forms.

The different permission modes are caused by different equipment forms of the electronic equipment, for example, if the collected face information passes verification in the unfolded state of the electronic equipment, the first permission mode is entered; if the collected face information passes verification under the bending state of the electronic equipment, entering a second permission mode.

Optionally, the first permission mode is higher than the second permission mode.

Optionally, the first permission mode includes: unlocking the auxiliary display screen; the second permission mode includes: and unlocking the main display screen.

Optionally, after unlocking the main display screen, all application programs in the electronic device are in a usable state; after unlocking the auxiliary display screen, the application program with the priority level lower than or equal to the preset priority level is in a usable state; application programs with priority levels higher than the preset priority level are in a disabled state.

Alternatively, different priority levels may be set for all applications installed by the electronic device.

Optionally, after unlocking the secondary display screen, one or more preset application programs are in a usable state, and other application programs are in a disabled state.

It can be understood that the unlocking operation is performed by using the face information collected by the called cameras of different groups, so that different permission modes can be entered.

Optionally, the feature objects contained in the face information that can be acquired by the cameras of different groups are different; it can be understood that the face unlocking operation is performed by using the face information containing different feature objects, and the false recognition rates are different. It can be appreciated that the lower the false recognition rate, the more secure it is for the electronic device.

The false recognition rate (FAR, false acceptance rate) refers to the fact that faces that should not be matched are regarded as matching faces, i.e. other users similar to the user's length are mistaken as the user himself.

Optionally, the feature object includes: the feature points (the feature points may include the Euclidean distance between eyes, and/or nose, and/or mouth, and/or ears), or the curvature between feature points, or the angle between feature points, and/or the face stereo information, etc.

For example, optionally, the second set of cameras may include: the 3D cameras can emit 3D structure light to the human face when the second group of cameras acquire the human face information; the 3D camera can collect a light image with depth, for example, a stereoscopic image of a face of a person can be obtained.

Optionally, the false recognition rate of face unlocking based on the face information acquired by the first group of cameras is lower than the false recognition rate of face unlocking based on the face information acquired by the second group of cameras. Or the false recognition rate of face unlocking based on the face information acquired by the first group of cameras is equal to the false recognition rate of face unlocking based on the face information acquired by the second group of cameras, or the false recognition rate of face unlocking based on the face information acquired by the first group of cameras is higher than the false recognition rate of face unlocking based on the face information acquired by the second group of cameras.

In the following, taking an example that the false recognition rate of face unlocking based on the face information acquired by the first group of cameras is higher than the false recognition rate of face unlocking based on the face information acquired by the second group of cameras, the explanation is made on the "executing unlocking operation by using the face information acquired by the called different groups of cameras, and being able to enter different permission modes".

If the face information acquired by the first group of cameras passes verification, entering a first permission mode; the first group of cameras are called when the electronic equipment is in a first equipment form, the first equipment form is a bending form, and the first group of cameras are cameras which are used for acquiring and windowing when the electronic equipment is in the bending state and are not shielded.

Optionally, if the face information collected by the first group of cameras passes verification, entering the first permission mode includes: and if the face information acquired by the first group of cameras passes the verification, controlling the auxiliary display screen to be in an unlocking state.

If the face information acquired by the second group of cameras passes verification, entering a second permission mode; the second group of cameras are called when the electronic equipment is in a second equipment form, the second equipment form is in an unfolding state, and the second group of cameras are cameras with the electronic equipment in the bending state and shielded from collecting and windowing.

Optionally, if the face information collected by the second group of cameras passes verification, entering the second permission mode includes: and if the face information acquired by the second group of cameras passes the verification, controlling the unlocking state of the main display screen.

In any of the above optional embodiments, optionally, if the face information collected by the first group of cameras passes verification, after unlocking the secondary display screen, the method is used for operating the application program with the lower priority level based on the secondary display screen; if the display area of the secondary display screen is smaller than the display area of the primary display screen, optionally, under the condition that the primary display screen is not unlocked, the user can operate the application program with the lower priority level by using the primary display screen.

In any of the above optional embodiments, optionally, if the face information collected by the first group of cameras passes verification, unlocking the secondary display screen; if the user needs to operate the application program with the higher priority level, the main display screen is unlocked based on the face information acquired by the second group of cameras, and the user can operate the application program with the higher priority level based on the main display screen.

In any of the above alternative embodiments, optionally, after the primary display is unlocked, the user may operate the application program with higher priority based on the secondary display (optionally, the secondary display has been unlocked or not unlocked)
