It can be seen that, in the embodiment of the invention, the mobile terminal firstly collects the face image; secondly, executing a first operation and a second operation in parallel, wherein the first operation is to detect whether the face image is a real face image, and the second operation is to match the face image with a preset face template; and finally, when the face image is successfully matched with the preset face template and the face image is a real face image, executing unlocking operation.

In one possible example, in terms of performing the first operation and the second operation in parallel, the processor 110 is specifically configured to: and executing the first operation at a first time node, executing the second operation at a second time node, wherein the time length required for executing the first operation is a first reference time length, the time length required for executing the second operation is a second reference time length, and the time difference between the first time node and the second time node is smaller than the time difference between the first reference time length and the second reference time length.

In a possible example, in the aspect that when it is detected that the face image is successfully matched with the preset face template and the face image is a real face image, the processor 110 is specifically configured to: and when the face image is successfully matched with the preset face template and the face image is a real face image, executing a third operation and a fourth operation in parallel, wherein the third operation is to remove the screen locking interface and load a system desktop, and the fourth operation is to light the touch display screen.
In a possible example, in the aspect that when it is detected that the face image is successfully matched with the preset face template and the face image is a real face image, the processor 110 is specifically configured to: when the face image is successfully matched with the preset face template, removing a screen locking interface; and the system is used for executing a third operation and a fourth operation in parallel when the face image is detected to be a real face image, wherein the third operation is to light up the touch display screen, and the fourth operation is to load a system desktop.
Referring to fig. 2, fig. 2 is a schematic flowchart of an unlocking control method according to an embodiment of the present invention, which is applied to a mobile terminal, and as shown in the figure, the unlocking control method includes:
s201, the mobile terminal collects a face image;
in a possible example, before the mobile terminal acquires a face image, the method further includes:
detecting an event to be unlocked;
and opening a front camera to capture a human face image.
The event to be unlocked may be, for example, a desktop event to be unlocked, an application event to be unlocked, a file event to be unlocked, or the like, which is not limited herein. The event to be unlocked by the desktop refers to an event to be unlocked for locking the desktop, the event to be unlocked by the application refers to an event to be unlocked for a specific operation of the application, such as application starting, application deleting and the like, and the event to be unlocked by the file refers to an event to be unlocked for the file, such as an event to be unlocked for a target file.
The event to be unlocked detected by the mobile terminal may be a detected event to be unlocked in a screen-off state, or a detected event to be unlocked in a screen-on state, where the trigger condition for detecting the event to be unlocked may be triggered by a touch operation, a pressing operation, a voice operation, and the like of a user, for example, for a mobile terminal in a screen-off standby state, the trigger condition may be not limited, and the trigger condition may be triggered by long pressing of a touch display screen.
S202, the mobile terminal executes a first operation and a second operation in parallel, wherein the first operation is to detect whether the face image is a real face image, and the second operation is to match the face image with a preset face template;
for example, the infrared sensor is used to detect whether the temperature distribution of the face conforms to the temperature distribution of the real face, or the face image is a three-dimensional face image, and the like, which is not limited herein.
The parallel execution of the first operation and the second operation may be a dual-process parallel operation of an operating system, or may also be a dual-process parallel operation of one process, or may also be a parallel operation of two CPUs of a dual-core system, which is not limited herein.
And S203, when the mobile terminal detects that the face image is successfully matched with the preset face template and the face image is a real face image, executing unlocking operation.
When the second operation matching fails, the mobile terminal interrupts the execution of the first operation, and power consumption of the mobile terminal is reduced.
When the matching degree of the face image and the preset face template is greater than a preset threshold, the face image and the preset face template are successfully matched, and the preset threshold may preset different preset thresholds according to different to-be-unlocked events, which is not limited herein.
The implementation manner of the mobile terminal executing the unlocking operation may be to switch the current state of the mobile terminal to an unlocking state, where the current state includes a screen locking state, a disabled state, and the like, and is not limited here.
The preset face template is a face data template, and the face data template refers to a set of corresponding relations between positions of feature points of a face of a registered user and feature values of the feature points (the feature values may be capacitances, inductances, voltages, currents, relative values, and the like).
It can be seen that, in the embodiment of the invention, the mobile terminal firstly collects the face image; secondly, executing a first operation and a second operation in parallel, wherein the first operation is to match the face image with a preset face template, and the second operation is to detect whether the face image is a real face image; and finally, when the face image is successfully matched with the preset face template and the face image is a real face image, executing unlocking operation. Therefore, the mobile terminal improves the safety of face unlocking of the mobile terminal by judging whether the face image is a real face image, and the first operation and the second operation are executed in parallel instead of in series, so that the time consumption is reduced, and the speed of unlocking control of the mobile terminal is improved.
In one possible example, the performing the first operation and the second operation in parallel includes:
and executing the first operation at a first time node, executing the second operation at a second time node, wherein the time length required for executing the first operation is a first reference time length, the time length required for executing the second operation is a second reference time length, and the time difference between the first time node and the second time node is smaller than the time difference between the first reference time length and the second reference time length.
Wherein the first reference duration is greater than the second reference duration.
The first time node and the second time node may be the same time node or different time nodes.
For example, the first reference time duration is 250ms, the second reference time duration is 120ms, the time difference between the first reference time duration and the second reference time duration is 130ms, and when the first time node is 32 minutes and 15 seconds and 20 milliseconds at 5 pm, the second time node may be any time node between 32 minutes and 15 seconds at 5 pm and 20 milliseconds at 32 minutes and 15 seconds at 5 pm and 150 milliseconds at 32 minutes and 15 seconds at 5 pm.
It can be seen that, in this example, the mobile terminal executes the first operation and the second operation in parallel at different time nodes, but not at the same time node, so that the first operation and the second operation may be executed in parallel, and the started time node may also be flexibly controlled, so that the mobile terminal may have additional flexible time to process higher-level events, which is beneficial to improving flexibility of the mobile terminal unlocking operation.
In one possible example, the performing the first operation at the first time node and the performing the second operation at the second time node includes:
allocating a first system resource to the first operation when the first time node executes the first operation;
and when the second time node executes the second operation, allocating a second system resource to the second operation, wherein the second system resource is smaller than the first system resource.
The first system resource and the second system resource may be determined according to an optimal allocation record in historical system resource allocation records, where the optimal allocation record may be a record with the fastest execution speed of the first operation and the second operation, or may be a preset mapping relationship between reference durations required by different operations and resource amounts of the required system resources, the mapping relationship is queried by using the first reference duration as a query identifier to determine the first system resource, and the mapping relationship is queried by using the second reference duration as a query identifier to determine the second system resource.
It can be seen that, in this example, the mobile terminal allocates different system resources according to different operation requirements, instead of blindly enabling the first operation and the second operation to use the same system resource, which is beneficial to reducing power consumption of the mobile terminal and improving accuracy of resource allocation.
In a possible example, the executing an unlocking operation when it is detected that the face image is successfully matched with the preset face template and the face image is a real face image includes:
and when the face image is successfully matched with the preset face template and the face image is a real face image, executing a third operation and a fourth operation in parallel, wherein the third operation is to remove the screen locking interface and load a system desktop, and the fourth operation is to light the touch display screen.
The event to be unlocked is a screen-off unlocking event.
The third operation is executed at a third time node, the fourth operation is executed at a fourth time node, the time length required for executing the third operation is a third reference time length, the time length required for executing the fourth operation is a fourth reference time length, and the time difference between the third time node and the fourth time node is smaller than the time difference between the third reference time length and the fourth reference time length.
The third time node and the fourth time node may be the same time node or different time nodes.
Therefore, in this example, the mobile terminal executes the third operation and the fourth operation in parallel on the basis of the parallel first operation and the parallel second operation, and performs double parallel operations, so as to further improve the unlocking processing speed of the mobile terminal.
In a possible example, the executing an unlocking operation when it is detected that the face image is successfully matched with the preset face template and the face image is a real face image includes:
when the face image is successfully matched with the preset face template, removing a screen locking interface;
and when the face image is detected to be a real face image, executing a third operation and a fourth operation in parallel, wherein the third operation is to light the touch display screen, and the fourth operation is to load a system desktop.
The event to be unlocked is a screen-off unlocking event.
It can be seen that, in this example, the mobile terminal executes the third operation and the fourth operation in parallel on the basis of the parallel first operation and the parallel second operation, and performs double parallel operations, so as to further increase the speed of the unlocking processing of the mobile terminal, and when the second operation succeeds before the first operation, the second operation makes full use of the extra time to execute other steps in the unlocking operation, instead of just waiting for the completion of the first operation, which is beneficial to improving the rationality of the execution of the unlocking operation of the mobile terminal, and when it is determined that the face image is successfully matched and is a real face image, the operation of lighting the touch display screen is performed, which is beneficial to reducing the power consumption of the mobile terminal.
