Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

When using a mobile terminal such as a mobile phone to take photos on a daily basis, the built-in attitude sensor, such as a gyroscope and/or an acceleration sensor, is often used to detect whether the mobile phone is in landscape or portrait mode, so as to determine whether the photographing mode is landscape mode or portrait mode. The orientation in which to generate the photo.

The inventors found that since the attitude sensor 500 of the mobile terminal can only detect the included angle in the direction of gravity, it cannot effectively detect the included angle in the horizontal direction, that is to say, it can only detect the pitch angle A of the mobile terminal as shown in Figure 1a and Figure 1b change and the change of roll angle B shown in Figure 2a and Figure 2b, but it is impossible to detect the change of yaw angle C of the mobile terminal as shown in Figure 3, such as only detecting that one end of the mobile terminal is higher than the other end, but not Detect angle changes when the mobile terminal is in a horizontal state. Therefore, when the user uses the mobile terminal to take photos horizontally, it is impossible to determine whether the mobile terminal should be in landscape or portrait orientation, which will easily lead to wrong orientation of the photos taken and affect user experience. For example, the user shoots an object in the horizontal state of the mobile phone as shown in Figure 4, and the user wants to shoot the object in a horizontal screen, but since it is impossible to determine whether to shoot in a horizontal screen or a vertical screen in a horizontal state, the mobile terminal may process the shooting mode It is a vertical screen shooting mode, and the obtained photos may be processed as photos taken in a vertical screen.

The inventor found through research that when a user takes a photo with the rear camera of a mobile terminal, the user usually faces the display screen, observes the picture preview on the screen, then adjusts the viewfinder and then clicks the camera button to take a photo. Therefore, the embodiments of the present application provide a shooting method, device, mobile terminal, and storage medium, which can determine the positional relationship between target objects such as faces and the mobile terminal according to the user's usage habits of the mobile terminal, and determine the user's desired location. Whether to shoot in landscape or portrait mode, accurately determine the shooting mode so that the direction of the generated photo is consistent with the viewing direction of the mobile terminal. That is, when viewing in landscape or portrait mode, the direction of the photo taken is consistent with the preview direction of the mobile phone. For example, the photo taken by the user in landscape mode can be displayed to the user after being rotated 90 degrees when viewing in portrait mode, so that the photo The direction in which the target object is presented to the user is consistent with the direction in which the user frames the view when shooting.

The client can be run on the mobile terminal. For example, in this application, the client running on the mobile terminal may be a camera. The photographing method and device provided in the embodiments of the present application will be described below mainly from the client side of the mobile terminal, in conjunction with the accompanying drawings and through specific embodiments. The mobile terminal may be a mobile phone, a tablet computer or other smart devices, and this application mainly uses a mobile phone as an example for illustration.

first embodiment

Referring to FIG. 5 , the first embodiment of the present application provides a shooting method. The shooting method is used to take pictures in the current shooting mode when shooting after moving the terminal according to the current shooting mode of the target object. In a specific embodiment, the shooting method is applied to the shooting device shown in FIG. 13 and the mobile terminal 500 corresponding to the shooting device 400 ( FIG. 14 , FIG. 15 , and FIG. 16 ), and the mobile terminal is provided with a camera 510 . The above-mentioned photographing method may specifically include the following steps:

Step S110: Obtain an image of the target object through the camera.

When the mobile terminal is in the shooting mode of taking pictures or videos with the camera turned on, in order to determine whether the mobile terminal should be in the landscape shooting mode or the portrait shooting mode, it can be judged according to the image of the target object that the camera can obtain. attitude to determine the shooting mode.

Specifically, an image of the target object may be acquired through a camera as the image of the target object. What kind of object the target object is specifically is not limited, and may be any image that can be acquired by the camera, or a symmetrical image that can be acquired by the camera.

Step S120: According to the positional relationship between the target object in the target object image and the mobile terminal, determine whether the current shooting mode is a landscape mode or a portrait mode.

The positional relationship between the target object and the mobile terminal in the target object image can reflect the relationship between the target object itself and the mobile terminal, thereby reflecting the current shooting posture of the mobile terminal. Therefore, the target object in the target object image can be The positional relationship with the mobile terminal determines the current shooting mode of the mobile terminal. The determined current shooting mode may be a landscape mode or a portrait mode.

Step S130: If a shooting instruction is received, use the determined current shooting mode to shoot.

If it is determined that the current shooting mode is landscape mode, after receiving the shooting instruction, shoot in landscape shooting mode; if it is determined that the current shooting mode is portrait shooting mode, then shoot in vertical screen mode after receiving the shooting command to shoot.

It can be understood that after the current shooting mode is determined, if no shooting instruction has been received, when the posture of the mobile phone changes, if the re-determined current shooting mode is different, when the shooting instruction is received, the shooting will be performed in the latest determined shooting mode .

In the embodiment of the present application, the current shooting mode can be determined according to the positional relationship between the target object and the mobile terminal in the target object image, so that when a shooting instruction is received, shooting is carried out according to the current shooting mode, effectively dealing with situations that cannot be determined by the attitude sensor. The mobile terminal corresponds to the horizontal screen state or the vertical screen state, so as to improve the user's photo taking experience.

second embodiment

An embodiment of the present application provides a shooting method, which mainly uses a human face as a target object to determine a current shooting mode. Since when the mobile terminal is in a non-horizontal state, the posture sensor can be used to determine whether the screen is in landscape or portrait mode. Therefore, this embodiment of the present application can be mainly used to determine the current shooting mode of the mobile terminal in the horizontal state. Specifically, please refer to Figure 6, the method includes:

Step S210: judging whether the mobile terminal is currently in a horizontal state or a vertical state according to the posture of the mobile terminal. If it is in the horizontal state, execute step S220; if it is in the vertical state, execute step S250.

When the camera is turned on, the attitude of the mobile terminal can be determined. Specifically, the attitude sensor of the mobile terminal can be used for determination. The specific attitude sensors are not limited in this embodiment of the application, such as accelerometers and/or gyroscopes Wait.

It can be understood that the horizontal state of the mobile terminal is not necessarily limited to the strictly horizontal state, but any state that has a certain angle with the horizontal plane can be defined as the horizontal state. The angle between the mobile terminal and the horizontal plane may be a pitch angle as shown in FIG. 1 , or a roll angle as shown in FIG. 2 .

Specifically, determining whether the mobile terminal is in a horizontal state or a vertical state may be to determine whether the angle between the display screen of the mobile terminal and the vertical direction is within a preset angle range; if so, then determine that the posture of the mobile terminal is in a horizontal state, If not, it is determined that the posture of the mobile terminal is in a vertical state. In other words, determine the angle between the display screen and the horizontal plane, and determine whether the mobile terminal is in a horizontal state according to the angle. For example, when the value of angle A in Figure 1 is within a preset range, it is determined that the mobile terminal is in a horizontal state. Wherein, the included angle between the display screen and the vertical direction may be an angle D as shown in FIG. The range can be between 60 degrees and 120 degrees.

Step S220: Obtain an image of the target object through the camera.

Because when the user uses the mobile phone camera to take pictures, in order to check the shooting effect, the user usually faces the display screen, observes the picture preview on the screen, and then adjusts the viewfinder. After the viewfinder is determined, click the camera button to take a photo. When shooting, there is a positional relationship between the user's face and the mobile terminal. Therefore, the user's face can be used as the target object, and the user's face image can be captured through the front camera of the mobile terminal as the target object image. The faces in the subject image determine the current capture mode.

Step S230: According to the positional relationship between the target object in the target object image and the mobile terminal, determine whether the current shooting mode is a landscape mode or a portrait mode.

When a user takes a picture through a mobile terminal, if the user's face is more inclined towards the landscape orientation, the user is more likely to be shooting in the landscape orientation; High, therefore, it can be determined whether the shooting mode is landscape mode or portrait mode according to the bias of the face in the image of the target object. Wherein, generally, the vertical screen direction is defined as the direction of the connection line aa' between the top a and the bottom a' of the mobile terminal as shown in Figure 7, that is, the direction from the top a to the bottom a' or the direction of the bottom a ' to the direction of the top a; the horizontal screen direction is defined as the direction of the connecting line bb' connecting the two side ends from the top to the bottom, as shown in FIG. 8 . Certainly, the horizontal screen direction and the vertical screen direction are not limited, and the directions corresponding to the horizontal screen shooting and the vertical screen shooting in the mobile terminal shall prevail.

When determining the shooting mode according to the face, it can be judged whether the face is in the landscape orientation or in the portrait orientation; if it is in the landscape direction, determine that the current shooting mode is landscape mode; if it is in the portrait orientation, determine that the current shooting mode is Portrait mode.

Among them, when judging whether the face is more inclined to the landscape orientation or the portrait orientation, the judgment can be made according to the facial features of the face. For example, the feature lines in the face are acquired according to the five sense features of the face; according to the relationship between the feature lines and the mobile terminal, it is determined whether the face is in a landscape orientation or a portrait orientation. For example, the face orientation is determined according to the angle between the feature line and the horizontal or vertical screen direction.

As a specific implementation manner, the determined feature line may be the central axis of the human face, that is, the dividing line between the left face and the right face of the human face, as shown in the central axis T of the human face in FIG. 9 . The method of determining the central axis is not limited in the embodiment of the present application. For example, the center of a human face can be determined according to facial features such as the hairline, eyebrow center, lower edge of the nose alar or chin tip in the collected facial images. axis.

Then, the face orientation is determined according to the positional relationship between the central axis and the mobile terminal. For example, the included angle between the central axis and the horizontal screen direction can be calculated as the first included angle E, and the included angle between the central axis and the vertical screen direction can be calculated as the second included angle E', as shown in FIG. 10 . If the first included angle is greater than the second included angle, it is determined that the human face is in a portrait orientation; if the second included angle is greater than the second included angle, it is determined that the human face is in a landscape orientation. If the first included angle is equal to the second included angle, it can be judged to be biased towards the horizontal screen direction, or it can be judged to be biased toward the vertical screen direction, or it can be judged to be the deflection determined before the first included angle is equal to the second included angle. In this application It is not limited in the embodiment, and can be set as required. Of course, when judging the orientation of the face according to the central axis, if the first included angle is greater than 45 degrees, it can be determined that the face is biased toward the portrait orientation, and if it is less than 45 degrees, it can be determined that the face is deflected to the landscape orientation.

Certainly, the determined feature line may also be other, for example, it may be a line perpendicular to the central axis. As another specific implementation manner, the determined feature line may be a connection line between two eyes of a face image, such as connection T' in FIG. 11 . Wherein, obtaining the connection line between the two eyes of the human face may be, first obtaining the positions of the two eyes in the human face image, and then determining the continuity between the two eyes according to the characteristics of the human eyes. When determining the face orientation according to the connection line between the two eyes, the angle between the connection line between the two eyes and the horizontal screen direction can be calculated as the third angle F, and the connection line between the two eyes and the vertical direction can be calculated as the third angle F. The included angle in the screen direction is the fourth included angle F', as shown in FIG. 11 . If the third included angle is greater than the fourth included angle, it is determined that the human face is biased in a landscape direction; if the fourth included angle is greater than the third included angle, it is determined that the human face is biased in a vertical screen direction. In addition, if the third included angle is equal to the fourth included angle, it may be determined that the orientation is in the landscape orientation, or it may be determined that the orientation is in the portrait orientation, or it may be determined as the orientation determined before the third included angle is equal to the fourth included angle.

Optionally, in this embodiment of the present application, the face recognition part may also include 3D structured light face recognition, and the axis direction of the face can also be accurately recognized by using 3D structured light.

Step S240: When a shooting instruction is received, use the determined current shooting mode to shoot.

When receiving a shooting instruction, if the current shooting mode is landscape mode, take a landscape photo, and the mobile terminal is a landscape preview, and the direction of the photo taken at this time is the same as that of the landscape preview; if the current shooting mode is portrait mode, Then take a vertical screen photo, and the mobile terminal is a vertical screen preview, and the direction of the photo taken at this time is the same as that of the vertical screen preview.

Step S250: Determine the current shooting mode according to the posture of the mobile terminal.

If the mobile terminal is in a vertical state, the shooting mode can be determined according to the posture of the mobile terminal determined by the posture sensor. For example, when the top or bottom end is higher than the other ends, it is determined to be a portrait shooting mode; when one side end is higher than the other ends, it is determined to be a landscape shooting mode.

To sum up, in the embodiment of this application, it can be determined according to the posture of the mobile terminal whether the mobile terminal is in a horizontal state or a vertical state. If it is in a horizontal state, it can be determined according to the positional relationship between the photographer's face and the mobile terminal. Determine whether the current shooting mode is landscape mode or portrait mode. Therefore, when shooting horizontally, the direction of taking photos can be set according to the user's actual preview direction, and there will be no problem that the direction of the photo taken by the user is rotated by 90° from the direction of the user's desired photo. It will not bring unnecessary trouble to the user to use the photos, and it is convenient for the user to use.

third embodiment

The embodiment of the present application provides a specific implementation process when shooting by the aforementioned shooting method. In the embodiment of this application, determine the coordinate system of the mobile phone, assuming that the mobile phone is placed in its default direction as shown in Figure 7, the X axis of the mobile phone coordinate system is horizontally pointing to the right, the Y axis is vertically upward, and the Z axis is pointing Outside the front of the screen, that is, the back of the screen is a negative value of Z.

When the user uses the mobile phone and the mobile phone moves or rotates, the coordinate axes in the mobile phone coordinate system will not change, that is, they follow the mobile phone. After the mobile phone sends motion or rotation, the change angle of each coordinate axis can be determined when the mobile phone coordinate system is relative to the default direction. Figure 12 shows the center of gravity of the mobile phone detected by the built-in gyroscope of the mobile phone and the predetermined X, Y, Z axes. Angle schematic diagram, define the corresponding angles of X, Y and Z axes as Rx, Ry, Rz respectively. When the user opens the rear camera preview, the built-in attitude sensor of the mobile phone detects the angles Rx, Ry, and Rz of the Z axis where the center of gravity deviates from the default direction, and the angles Rx, Ry, and Rz that are close to the X axis and the Y axis. Set A as the angle margin. The size of A is not limited and can be adjusted according to the actual debugging effect. For example, the value of A may be between 0°-30°. When |Rz-90°|>90°-A is detected, it is determined that the mobile phone is in a vertical state, and if |Ry-90°|> |Rx-90°|, it is determined that the mobile phone is placed vertically, and the photo generated by taking pictures The orientation is the same as that of the portrait preview; if |Ry-90°|<=|Rx-90°|, it is judged that the mobile phone is placed in landscape orientation, and the direction of the photo generated by taking a photo is the same as that of the landscape preview. When |Rz-90°|<=90°-A is detected, it is determined that the mobile phone is placed horizontally. At this time, the mobile phone turns on the front camera to collect face recognition images.

Face recognition can determine the central axis of the face mainly based on facial features such as the hairline, brow center, lower edge of the nose, and tip of the chin in the collected face images. Then compare the angle between the central axis of the face and the X and Y axes of the mobile phone. When it is determined that the angle between the central axis and the X axis is greater than the angle between the central axis and the Y axis, it is determined that the mobile phone is in a horizontal position and a vertical screen preview, and the direction of the photo taken at this time is the same as that of the vertical screen preview. Conversely, when it is determined that the angle between the central axis and the Y axis is not smaller than the angle between the central axis and the X axis, it is determined that the mobile phone is a horizontal landscape preview, and the direction of the photo taken at this time is the same as that of the landscape preview.

In the embodiment of the present application, when the attitude sensor such as the built-in acceleration/gyroscope sensor detects that the shooting position of the mobile phone is horizontally downward shooting, the face image can be collected through the front camera, and the angle between the face and the longitudinal axis of the mobile phone screen can be judged. Then adjust the direction of the mobile phone to take the photo, so that the direction of the mobile phone to take the photo is consistent with the direction of the preview of the mobile phone.
