Referring to fig. 2A, fig. 2A is a schematic flowchart of an image data obtaining method according to an embodiment of the present invention, applied to a mobile terminal, where as shown in the figure, the image data obtaining method includes:
s201, the mobile terminal detects a starting request of a camera;
the method includes that a mobile terminal detects a start request of a camera in a screen-off state or in a screen-on state, the mobile terminal detects the start request of the camera, the mobile terminal detects a start request of a user for a camera application, the camera application triggers the start request of the camera to take a picture, the mobile terminal detects a screen to-be-unlocked event and performs face recognition unlocking on the start request of the camera, or the mobile terminal detects a payment unlocking event (for example, a to-be-unlocked event in a payment scene of an application such as a pay bank or a WeChat) and performs face unlocking recognition on the start request of the camera, and the like, and is not limited uniquely.
The mobile terminal comprises a face unlocking module, the face unlocking module is used for triggering the camera to acquire face image data, the face image data returned by the camera is processed, the face image data is matched with preset face image data, unlocking operation is triggered after the matching is successful, and unlocking events such as unlocking events and payment unlocking events can be triggered by the face unlocking module on a screen of the mobile terminal.
The start request of the camera may be a start request of a front camera, a start request of a rear camera, or a start request of two cameras, which is not limited herein.
S202, the mobile terminal selects a preset control in a preset control set according to the type of the starting request, wherein the preset control set comprises a native control and the preset control;
the type of the starting request can be classified according to an event targeted by the starting request, for example, the starting request is classified into a photographing type, an unlocking type, a payment type and the like, wherein the photographing type needs to perform interface drawing of image data and corresponds to a preview interface control in the native control, the unlocking type and the payment type do not need to perform interface drawing of the image data and correspond to a non-preview interface control in the native control or the preset control; or the type of the start request may be classified according to whether interface drawing display of the data acquired by the camera is required, for example, the data is classified into a first type requiring interface drawing and a second type not requiring interface drawing, and the like, which is not limited herein.
The native control comprises two photo controls which are commonly used by the current mobile terminal, as shown in fig. 2B, one is a control with a preview interface, the control is used for starting the camera to indicate that the camera needs to return data to an application or a module which sends the control for image data processing after acquiring image data, and the control comprises an interface to be drawn and indicates that the camera needs to draw the interface and upload the interface to a desktop for display after acquiring the image data; and the other control is a control without a preview interface, the use of the control to start the camera indicates that the camera also needs to return data to an application or a module sending the control for image data processing after acquiring image data, and the control also comprises an interface to be drawn, and indicates that the camera needs to draw the interface after acquiring the image data, but the interface does not need to be displayed on the interface of the mobile terminal. Therefore, in the native control, no matter there is a control with a preview interface or a control without a preview interface, copying and interacting of data between a camera application and an image rendering service corresponding to the camera and a calculation rendering operation of the central processing unit are required in the operations of rendering, uploading and displaying of image data, so that when an interface rendering operation is not required, the use of the control without the preview interface causes system resource waste and excessive consumption of electric quantity.
For example, as shown in fig. 2B, when the mobile terminal detects a start request of a camera, an application a triggering the start request sends a native control to the camera or controls a camera-type application of the camera, where the native control indicates that image data needs to be returned to an original application interface and provides an interface to be drawn, and therefore the camera or the camera-type application acquires the image data after receiving the native control, returns the image data to the application a for image data processing, performs interface drawing according to the image data, and uploads the image data to a desktop for display.
The preset control is a user-defined control required by the application, as shown in fig. 2C, the preset control indicates that the camera only needs to transmit the acquired image data to an application or a module which triggers the start of the camera, and an interface to be drawn is not provided, so that the camera application corresponding to the camera does not need to perform interface drawing and display operation on the acquired data.
For example, as shown in fig. 2C, when the mobile terminal detects a start request of a camera, an application a triggering the start request sends a preset control to the camera or controls a camera type application of the camera, where the preset control only indicates that image data needs to be returned to an original application interface, and therefore, the camera or the camera type application acquires the image data after receiving the preset control and returns the image data to the application a for image data processing.
And S203, the mobile terminal acquires the face image data according to the preset control and executes face unlocking operation according to the face image data.
The specific implementation manner of the mobile terminal acquiring the face image data according to the preview control may be various, for example, the image data in the preview interface may be acquired according to the current focal length, and then the image data is screened and identified to obtain the required face image data, or the required face image data may be acquired by blurring focusing or determining the distance from the camera in the process of acquiring the image data, and the like, which is not limited herein.
For example, the specific implementation manner of performing the face unlocking operation according to the face image data is various, and the specific implementation manner is not limited herein, and the face image recognition unlocking operation may be performed according to data of all pixel points of the face image, or may be performed according to unique feature data (such as scars, moles, and the like) of users in data of pixel points in a partial image of the face image.
It can be seen that, in the embodiment of the present invention, the mobile terminal first detects a start request of the camera; secondly, selecting a preset control in a preset control set according to the type of the starting request, wherein the preset control set comprises a native control and the preset control; and finally, acquiring the face image data according to the preset control, and executing face unlocking operation according to the face image data. Therefore, when the mobile terminal detects a starting request of the camera, the type of the starting request is determined through scene recognition, the preset control added besides the native control is selected according to the type of the starting request, the defects caused by the fact that the native control is used completely are avoided, the diversity of data acquisition of the mobile terminal is improved, in addition, only the face unlocking operation is executed on the acquired face image data according to the preset control, and the electric quantity consumption and the resource occupation caused by the fact that the native control previews the interface drawing operation when the camera is used are reduced.
In a possible example, the selecting a preset control in a preset control set according to the type of the start request includes:
determining the type of the starting request according to the starting request;
and when the operation corresponding to the starting request does not comprise the drawing operation aiming at the camera preview interface according to the type, selecting the preset control in the preset control set.
When the type is the payment type, the unlocking type or the second type, the operation corresponding to the starting request does not include a drawing operation for the camera preview interface.
The mobile terminal may preset a corresponding relationship between the type of the start request and whether the mobile terminal includes a drawing operation for the camera preview interface, and determine whether the operation corresponding to the type includes the drawing operation for the camera preview interface according to the corresponding relationship.
As can be seen, in this example, the mobile terminal first determines the type of the start request, and selects the preset control when it is determined according to the type of the start request that the operation corresponding to the type does not include the drawing operation for the camera preview interface, which is beneficial to accurately selecting the corresponding space by the mobile terminal and improves the accuracy of data processing.
In one possible example, after detecting the start request of the camera, the method further includes:
determining the type of the starting request according to the starting request;
when the operation corresponding to the starting request is judged to comprise drawing operation aiming at the camera preview interface according to the type, selecting the native control in the preset control set;
and acquiring image data of the camera preview interface, and executing the processing operation of the image data and the interface drawing operation of the image data in parallel according to the native control.
After the native control is determined, it may be determined that an event corresponding to the start request of the camera is not a face unlocking event, and therefore, the acquired image is not only a face image, but all image data in the current camera preview interface, or image data acquired according to the operation of the user.
As can be seen, in this example, when the mobile terminal determines that the corresponding operation includes a drawing operation for the camera preview interface according to the type of the start request, the mobile terminal selects the native control, and determines that the acquired image data is image data in the preview interface instead of face data according to the native control, which is beneficial to improving accuracy of data acquisition and increasing speed of data acquisition.
In one possible example, the determining the type of the initiation request according to the initiation request includes:
acquiring an event to be executed which triggers the starting request;
and determining the type of the starting request according to the event to be executed.
The event to be executed may be the above-mentioned event to be unlocked for payment, event to be unlocked for screen, event to be shot by camera, or the like, which is not limited herein.
For example, the mobile terminal detects that the event to be executed is a payment event to be unlocked, the face unlocking module executing the payment event to be unlocked triggers the starting request of the camera, and the type of the starting request can be determined according to the payment event to be unlocked.
The mobile terminal may be configured to preset, by a technician before shipment, a mapping relationship between the event to be executed and the type of the start request, and determine the type of the start request according to the mapping relationship.
Therefore, in this example, the mobile terminal first acquires the event to be executed that triggers the start request, and determines the type of the start request according to the event to be executed, which is beneficial to improving the convenience of data acquisition of the mobile terminal and improving the efficiency of data acquisition.
In this possible example, the determining the type of the initiation request according to the event to be executed includes:
and querying a preset mapping relation between the event to be executed and the type by using the event to be executed as a query identifier, and determining the type of the starting request corresponding to the event to be executed, wherein the type of the starting request comprises a first type and a second type, the operation corresponding to the first type comprises a drawing operation aiming at the camera preview interface, and the operation corresponding to the second type does not comprise the drawing operation aiming at the camera preview interface.
Therefore, in this example, the mobile terminal divides the type of the start request into the first type and the second type according to whether the preview interface of the camera needs to be drawn, instead of dividing the type into a plurality of types according to the purpose of the event to be executed, so that the classification of the types is simplified, the convenience of the mobile terminal in selecting the control is improved, and the processing efficiency of the mobile terminal is improved.
In one possible example, the acquiring the facial image data according to the preset control includes:
determining image data of the camera preview interface to be acquired as face image data according to the preset control;
identifying at least one face image in the camera preview interface;
determining a face image occupying the largest area of the camera preview interface in the at least one face image;
