The following method, apparatus, electronic device or computer-readable storage medium in the embodiments of the present application may be applied to any scenario that requires auxiliary shooting, and the embodiments of the present application do not limit specific application scenarios, and any scheme that uses the auxiliary shooting method and apparatus provided in the embodiments of the present application is within the scope of the present application.
It is noted that, before the present application is proposed, as technology develops, the phenomenon of taking a picture using a smart device has become very common. The common shooting mode mainly comprises two conditions of single self-shooting and multi-person shooting. In the process of one-man self-timer shooting, a photographer needs to adjust the position relation between the intelligent device and the face for multiple times, and a good shooting effect can be obtained. In the process of shooting by multiple persons, due to different position relations between multiple shooting targets and the camera, the near persons are easy to shoot large round faces and large chin, and the far persons are easy to shoot small faces.
Although the photographed image can be subjected to image correction, if the original image is not good in photographing effect, a perfect photographed image cannot be obtained after image correction, so that the simple photographing and the good photographing effect are common pursuits.
In view of the foregoing problems, embodiments of the present application provide an auxiliary shooting method, an auxiliary shooting apparatus, an electronic device, and a computer-readable storage medium, so as to implement at least one of the following: the method comprises the steps of prompting adjustment of a shooting position for a user shooting through the terminal equipment or correcting a shooting target with an imperfect shooting position to obtain a perfect shooting image.
For the convenience of understanding of the present application, detailed descriptions of an auxiliary shooting method, an auxiliary shooting device, an electronic device, and a storage medium provided in the embodiments of the present application are provided below.
Referring to fig. 1, in an auxiliary shooting method provided in the embodiment of the present application, the auxiliary shooting method shown in fig. 1 may be executed in a terminal device, and as shown in fig. 1, the auxiliary shooting method specifically includes:
s101: identifying a target shooting object in a shooting interface of the terminal equipment;
s102: determining the relative position between a target shooting object and the terminal equipment;
s103: determining a target shooting mode of a target shooting object at the determined relative position;
s104: and shooting the target shooting object based on the determined target shooting mode.
The above exemplary steps provided by the embodiments of the present application are described below by taking the application of the above method to a terminal device as an example.
In step S101, the terminal device refers to an electronic device that is held by the photographer and used for shooting, and may be an electronic device having a shooting function, such as a mobile phone, a tablet computer, a Personal Digital Assistant (PDA), a video camera, or a game machine.
In this embodiment, the shooting interface refers to a shooting preview interface displayed on a screen of the terminal device after the terminal device starts a shooting function, for example, after a camera is started, and a captured preview screen is displayed in the shooting interface.
The target photographic subject may include, but is not limited to, a person, an animal, and an object appearing in the photographic interface, and for example, in the case where the target photographic subject is a person or an animal, at least a face image of the target photographic subject may be included in the photographic interface.
Illustratively, the terminal device may have a front camera and a rear camera, and the preview screen displayed in the shooting interface may be a screen captured by the front camera or a screen captured by the rear camera.
Specifically, the photographer starts a shooting function of the terminal device, aims the lens at a target shooting object to be shot, and the terminal device recognizes the target shooting object from the shooting interface.
In step S102, for example, the relative position between the target photographic subject and the terminal device may be a straight-line distance from a target area (such as a center point of a face) of the target photographic subject to a center point of a camera of the terminal device.
In the embodiment of the present application, the target area of the target photographic object may be identified from the preview image of the photographic interface, and here, the target area of the target photographic object may be identified from the preview image through various image identification methods, which is not limited in the present application. For example, a contour of the target photographic subject may be recognized from the preview image, and a center point of the recognized contour may be determined as the target area. For example, the target area may be a center point of a contour of the object in the case where the target object is an object, the recognized contour may be a face contour in the case where the target object is a person or an animal, and the target area may be a center point of a face.
For example, the terminal device of the present application may include a depth camera, and the depth camera captures depth data of a target photographic subject, so as to determine a relative position between the target photographic subject and the terminal device.
As an example, in the embodiment of the present application, the camera used for capturing the preview screen displayed in the shooting interface may be the depth camera described above, or may be another camera configured in the terminal device besides the depth camera.
For the case that the terminal device is configured with a depth camera and a normal camera, the normal camera may be started, and a preview picture captured by the normal camera is displayed in a shooting interface, and at the same time, a shooting direction of the normal camera is determined (here, it may also be determined whether the normal camera belongs to a front camera or a rear camera), whether the shooting direction of the depth camera is consistent with the shooting direction of the normal camera is determined, if the shooting directions of the depth camera and the normal camera are consistent (for example, both belong to a front arrangement mode or both belong to a rear arrangement mode), the depth camera is started to determine a relative position between a target shooting object and the terminal device, and if the shooting directions of the depth camera and the normal camera are not consistent (for example, both the front arrangement mode and the rear arrangement mode are respectively adopted), the auxiliary shooting method is not executed.
In a preferred embodiment, two depth cameras may be provided, one of which is arranged in a front position to capture images in front of the terminal device and the other of which is arranged in a rear position to capture images behind the terminal device. Therefore, the auxiliary shooting method can be executed when any one of the front-end camera and the rear-end camera is started.
In step S103, the target shooting mode at least includes a shooting orientation adjustment shooting mode and a portrait adjustment shooting mode, for example, the shooting orientation adjustment shooting mode is used to adjust the shooting orientation of the terminal device, and the portrait adjustment shooting mode is used to adjust the portrait of the target shooting object in the shooting interface. The shooting direction adjusting shooting mode can comprise an automatic adjusting mode and a manual adjusting mode, and under the manual adjusting mode, a photographer can be informed of prompt information so as to adjust the shooting direction of the terminal equipment; the portrait adjustment shooting mode is to correct the preview image of the target shooting object presented in the shooting interface. However, any of the above-described imaging methods is realized when the relative position between the target imaging object and the terminal device is determined.
Further, the target shooting style for the target shooting object may be determined in the following manner.
In the first case, the portrait adjusting shooting mode is selected by triggering the portrait adjusting control.
For example, a portrait adjusting control may be displayed on the shooting interface, in which case, in response to a triggering operation of the portrait adjusting control on the shooting interface, the portrait adjusting shooting mode for the target shooting object is determined as the target shooting mode.
For example, the portrait adjusting control may be a portrait beautifying button displayed in the shooting interface, and when the portrait beautifying button is selected, the portrait adjusting shooting mode is selected as the target shooting mode.
In the second case, the shooting azimuth adjustment shooting mode is selected by the trigger operation of the device adjustment control.
For example, a device adjustment control may be further displayed on the shooting interface, and in this case, in response to a trigger operation on the device adjustment control on the shooting interface, the shooting orientation adjustment shooting mode for the terminal device is determined as the target shooting mode.
For example, the device adjustment control may be a focus button displayed in the shooting interface, and when the focus button is selected, the shooting orientation adjustment shooting mode is selected as the target shooting mode.
It should be understood that the present application is not limited thereto, and may also respond to a focusing operation performed on the shooting interface, which may include a click focusing operation performed on the shooting interface for a certain target shooting subject, at which time the shooting orientation adjustment shooting mode is selected as the target shooting mode.
In the third case, the target shooting mode is determined according to the number of target shooting objects in the shooting interface.
For example, if the number of target subjects in the imaging interface is one, the imaging bearing adjustment imaging method is selected as the target imaging method, and if the number of target subjects in the imaging interface is plural, the portrait adjustment imaging method is selected as the target imaging method.
In step S104, the target photographic subject is photographed based on the target photographic manner determined in step S103 to generate a photographic image containing the target photographic subject.
For example, a current shooting orientation of the terminal device at the determined relative position may be determined, and a deviation between the current shooting orientation of the terminal device and a target shooting orientation at the determined relative position may be determined; and shooting the target shooting object according to the deviation. Here, the current shooting orientation of the terminal device may be adjusted or the display size of the target photographic subject within the shooting interface may be adjusted according to the above-described deviation to perform shooting.
And acquiring the current shooting direction of the terminal equipment at the determined relative position and acquiring the target shooting direction of the terminal equipment at the relative position based on the relative position of the current terminal equipment and the target shooting object under the condition that the target shooting mode is the shooting direction adjustment shooting mode. And adjusting the current shooting position of the terminal equipment according to the deviation between the current shooting position and the target shooting position. For example, the prompt information may be generated according to the deviation to prompt the photographer to adjust the shooting orientation between the terminal device and the target shooting object, and when the difference between the shooting orientation and the target shooting orientation is close to zero, it indicates that the position relationship and the shooting angle between the current terminal device and the target shooting object are appropriate, and the prompt information is not sent.
Determining the current shooting direction of the terminal equipment at the determined relative position based on the relative position between each target shooting object and the terminal equipment after receiving a shooting instruction for shooting an image according to the condition that the target shooting mode is the image adjustment shooting mode; determining the deviation between the current shooting orientation of the terminal equipment and the target shooting orientation at the relative position to obtain a corresponding preset image position, calculating a difference value based on the preset image position and the image position of the current target shooting object in the shooting interface, correcting the image position of the target shooting object in the shooting interface according to the difference value, and adjusting the display size of the target shooting object in the shooting interface according to the deviation to generate a shooting image.
In the embodiment, the relative position of the target shooting object and the terminal equipment is determined by automatically identifying the target shooting image in the shooting interface of the terminal equipment, and in one case, corresponding prompt information is generated according to the relative position and the shooting direction of the terminal equipment and the target shooting object, so that the optimal shooting position is formed between the target shooting object and the terminal equipment for image shooting; in another situation, the display size of the target shooting object in the shooting interface is calculated and corrected according to the relative position and the shooting direction of the terminal equipment and the target shooting object, so that each portrait in the shot image presents a better angle and effect no matter when a single person or a plurality of persons shoot, a good original image base can be provided for repairing the image, the image repairing step can be even omitted, and the requirement that people seek beautification by using intelligent equipment to shoot the portrait is met.
Further, the terminal device comprises a depth camera, and the relative position is determined by the depth camera. The depth camera here can output a normal planar shot image and also output depth information (i.e., a relative position in the present application) of a shot object, and the image information output by the depth camera includes three-dimensional position and size information, so that the terminal device can obtain three-dimensional stereo data of a corresponding shooting background and the shot object in the shot image.
Illustratively, the depth camera herein may be a structured light depth camera, a binocular stereo depth camera, and a time of flight depth camera. Structured light depth cameras are preferred here, which are suitable for being arranged on small terminal devices and with which the terminal device is configured to be relatively cost-effective.
Next, a process of photographing a target photographic subject in a case where the target photographic mode is a photographing orientation adjustment photographic mode will be described with reference to fig. 2.
Fig. 2 is a flowchart of a step of adjusting a shooting mode to shoot a target shooting object based on a shooting orientation according to an embodiment of the present application. As shown in fig. 2, specifically includes:
s201: determining the current shooting direction of the terminal equipment at the determined relative position;
s202: determining the deviation between the current shooting position of the terminal equipment and the target shooting position at the relative position;
s203: and according to the deviation, adjusting the current shooting orientation of the terminal equipment to shoot.
In step S201, the shooting orientation here includes, but is not limited to, a first angle value for characterizing a value of a pinch angle formed by the terminal device and the line and the vertical direction of the target photographic subject, and a second angle value for characterizing a value of a pinch angle formed by the terminal device and the line and the horizontal direction of the target photographic subject.

Fig. 4 is a schematic diagram of a second angle value used for characterizing an included angle value formed by a connecting line between the terminal device and the target photographic object and a horizontal direction according to an embodiment of the present application.

For example, assuming that a coordinate system is constructed with the position of the terminal device D as the origin of coordinates (e.g., the lens center of the depth camera), the coordinate position of the target object C in the constructed coordinate system can be determined by the depth camera, and the linear distance s between the terminal device and the target object can be calculated according to the coordinate position of the target object C0Here, s0The method is used for representing the relative position between the terminal equipment and the target shooting object, and can also calculate a first angle value of an included angle value formed by a connecting line and the vertical direction of the terminal equipment and the target shooting object

For example, a shooting data set may be constructed in advance, and a target shooting orientation corresponding to the current relative position may be determined based on the constructed shooting data set.
The target photographing orientation herein may include a first target angle value for representing a pinch angle value formed by the optimal photographing orientation with a line and a vertical direction of the target photographing object and a second target angle value for representing a pinch angle value formed by the optimal photographing orientation with the line and a horizontal direction of the target photographing object. That is, a first target angle value formed by a connecting line and a vertical direction of the terminal device and the target photographic object at the determined relative position

In fig. 6, C is a target position corresponding to the second target angle in the top view direction.

Fig. 7 is a flowchart of a step of adjusting a current shooting orientation of a terminal device according to an embodiment of the present application. As shown in fig. 7, in step S203, the step of adjusting the current shooting orientation of the terminal device to perform shooting according to the deviation specifically includes the following steps:
s301: determining a first deviation direction of the current shooting azimuth of the terminal equipment relative to the target shooting object in the vertical direction according to the first angle difference;
s302: determining a second deviation direction of the current shooting azimuth of the terminal equipment relative to the target shooting object in the horizontal direction according to the second angle difference;
s303: and adjusting the current shooting orientation of the terminal equipment according to the determined first deviation direction and the second deviation direction to shoot.
In step S301, a first deviation direction of the current shooting orientation of the terminal device at the determined relative position with respect to the target shooting orientation in the vertical direction is determined according to the first angle difference, and first prompt information for prompting the user to change the shooting angle of the terminal device in the vertical direction is generated according to the first deviation direction. And if the first angle difference is zero, not generating the first prompt message.
In step S302, a second deviation direction of the current shooting orientation of the terminal device in the determined relative position with respect to the target shooting orientation in the horizontal direction is determined according to the second angle difference, and second prompt information for prompting the user to change the shooting angle of the terminal device in the horizontal direction is generated according to the second deviation direction. And if the second angle difference is zero, not generating second prompt information.
In step S303, the first prompt message and/or the second prompt message generated in steps S301 and S302 are displayed in the shooting interface of the terminal device to prompt the photographer to adjust the shooting orientation of the terminal device and the target shooting object according to the prompt message.
Fig. 8 shows a schematic diagram that shows the first prompt message and/or the second prompt message displayed on the shooting interface according to the embodiment of the present application.
In this example, the first prompt information may include adjustment instruction information in a vertical direction, which is a direction for prompting the user to adjust the terminal device, and the adjustment in accordance with the prompted direction may move the terminal device to the target shooting orientation. The second prompt information may include adjustment instruction information in a horizontal direction, where the direction indicated by the adjustment instruction information is a direction for prompting a user to adjust the terminal device, and the adjustment according to the prompted direction may move the terminal device to the target shooting orientation.
It should be understood that the present application is not limited thereto, and the above prompt information may also be information for prompting the user to adjust the orientation of the user, for example, prompting the user to turn the head or adjust the height of the body. In the above example, graphics (e.g., "← ↓ → ↓") are used as the presentation information, but the present application is not limited thereto, and the presentation information may be presented in text on the imaging interface, or the presentation information may be played back in a language.
In a preferred example, the prompt information displayed on the shooting interface may further include third prompt information, in which case, if it is detected that the relative position between the target photographic subject and the terminal device is changed during the process of changing the shooting angle of the terminal device by the user, the third prompt information is displayed on the shooting interface for prompting the user to adjust the terminal device to eliminate the change. The reason why the third prompt message is displayed is that, considering that the adjustment of the shooting orientation depends on the relative position between the terminal device and the target shooting object, if the relative position between the terminal device and the target shooting object changes during the adjustment of the shooting orientation, the first target angle value and the second target angle value at the relative positions also change accordingly, which results in that the terminal device cannot achieve the best shooting effect even if the terminal device is adjusted to the target shooting orientation. Based on this, the third prompt information can be displayed in the shooting interface, so that the user can keep the relative position between the terminal device and the target shooting object unchanged as much as possible in the process of adjusting the shooting direction of the terminal device, and the best shooting effect is achieved.
Taking the above-mentioned fig. 8 as an example, a three-dimensional prompt graphic may be displayed in the shooting interface, a first direction of the three-dimensional prompt graphic indicates a horizontal direction, a user is prompted to adjust a shooting angle of the terminal device in the horizontal direction based on prompt information in the first direction, a second direction of the three-dimensional prompt graphic indicates a vertical direction, a user is prompted to adjust a shooting angle of the terminal device in the vertical direction based on prompt information in the second direction, a third direction of the three-dimensional prompt graphic indicates a front-back direction (i.e., a direction in which the terminal device approaches the target shooting object and a direction in which the terminal device moves away from the target shooting object), and a distance between the terminal device and the target shooting object is prompted to be adjusted based on prompt information in the third direction.
In the embodiment of the application, besides the above manner of prompting the user to manually adjust the shooting orientation of the terminal device, the current shooting orientation of the terminal device can be changed by controlling the rotation of the holder connected with the camera. Here, the camera connected to the pan/tilt head is a camera for capturing a shooting interface in the terminal apparatus.
In an optional embodiment, the auxiliary shooting method may further include: and if the shooting direction adjusted by the terminal equipment is consistent with the target shooting direction, canceling the prompt message displayed on the shooting interface. Here, the first prompt information may be cancelled if the first angle value in the vertical direction coincides with the first target angle value, and the second prompt information may be cancelled if the second angle value in the horizontal direction coincides with the second target angle value.
In addition, the auxiliary shooting method may further include: if the shooting direction adjusted by the terminal equipment is consistent with the target shooting direction, the target shooting object is automatically shot in the target shooting direction, and here, shooting can be directly and automatically carried out, or shooting can be carried out in response to a shooting instruction after the shooting direction is consistent with the target shooting direction.
In a preferred example, if the shooting orientation adjusted by the terminal device is consistent with the target shooting orientation, the user is prompted in a preset prompting manner that the current shooting orientation is adjusted to the target shooting orientation, and after the preset prompting manner is set, the target shooting object is shot in the above manual or automatic manner.
As an example, the preset prompting manner may include, but is not limited to, any one of the following: the method includes the steps of emitting prompt tones (e.g., a droplet, a beep), displaying a mark (e.g., a graphic mark, a text mark) indicating adjustment to a target shooting orientation in a shooting interface, performing voice broadcast, and canceling prompt messages displayed on the shooting interface of the terminal device.
The standard for judging the consistency of the shooting orientation adjusted by the terminal device and the target shooting orientation is that the absolute value of the first angle difference and/or the second angle difference is smaller than a preset range. For example, a person skilled in the art may set the value of the preset range according to actual needs.
Fig. 9 is a flowchart of a step of adjusting a shooting mode to shoot a target shooting object based on a portrait according to an embodiment of the present application. As shown in fig. 9, the specific steps include:
s401: determining the current shooting direction of the terminal equipment at the determined relative position;
s402: determining the deviation between the current shooting position of the terminal equipment and the target shooting position at the relative position;
s403: and according to the deviation, adjusting the display size of the target shooting object in the shooting interface to shoot.
In step S401, the current shooting orientation includes a relative angle between the terminal device and the target shooting object, where the relative angle may include a first angle value used to represent a included angle value formed by a connecting line between the terminal device and the target shooting object and a vertical direction and a second angle value used to represent a included angle value formed by a connecting line between the terminal device and the target shooting object and a horizontal direction.
In step S402, the target photographing orientation includes a target photographing angle at the determined relative position, the target photographing angle including a first target angle value for representing a pinch angle value formed by the optimal photographing orientation with a line and a vertical direction of the target photographing object and a second target angle value for representing a pinch angle value formed by the optimal photographing orientation with the line and a horizontal direction of the target photographing object. Here, the manner of determining the target shooting orientation may refer to the manner of determining the target shooting orientation in step S202 of fig. 2, and details of this portion are not repeated in this application.
The deviation includes an angle difference between the relative angle at the current relative position and the target photographing angle. Here, the calculation method of the angle difference between the relative angle and the target photographing angle may refer to the calculation method of the deviation between the current photographing orientation and the target photographing orientation determined in step S202 of fig. 2 described above.
In step S403, the occupation area of the face region of the target photographic subject within the photographic interface may be adjusted according to the deviation to perform photographing.
For example, the shooting position related data may further include a correction value and/or a corresponding correction method in a preset shooting data set. The correction value may be an angle difference between the relative angle and the target photographing angle, or may be a degree value set based on different relative positions and their corresponding angle differences to characterize the adjustment of the image display size. A corresponding correction method may also be set in advance based on each correction value.
For example, the occupied area of the face region in the shooting interface may be reduced according to an absolute value or a degree value of the angle difference, and the reduction is more obvious when the absolute value or the degree value is larger.
For example, when the correction value is an angle difference between the relative angle and the target photographing angle, the face image of the target photographing object is moved by a predetermined number of pixel points in the preset direction according to the area, so as to reduce the occupied area of the face area of the target photographing object. Here, the face region may be moved inward by a certain number of pixel points in the vertical direction according to the absolute value of the angle difference in the vertical direction, and/or the face region may be moved inward by a certain number of pixel points in the horizontal direction according to the absolute value of the angle difference in the horizontal direction. The number of the moving pixels changes along with the change of the absolute value of the angle difference, the larger the absolute value is, the more the number of the moving pixels is, and the smaller the absolute value is, the less the number of the moving pixels is.
In a preferred embodiment, the auxiliary shooting method of the present application can be further applied to shooting of a plurality of shot objects.
For example, when a plurality of photographic subjects are included in the photographic interface, the target photographic subject can be determined in the following manner: in response to selection of any one of a plurality of photographic subjects within the photographic interface, the selected photographic subject is determined as a target photographic subject.
Specifically, when a plurality of shooting objects are included in the shooting interface, the mode of multi-person shooting is described, and when a photographer clicks and focuses on one shooting object in the shooting interface through the terminal device or the camera automatically focuses on one shooting object, the shooting object is used as a target shooting object. In this case, the adjustment can be performed based on the one target photographic subject in the above manner.
In another embodiment, in the case where the target photographic subject includes a plurality of persons, multi-person photographing may be performed in the following manner.
For example, the target photographing mode may include a portrait adjustment photographing mode, and the relative position may include a relative position between each target photographing object and the terminal device.
In this case, the step of photographing the target photographic subject based on the determined target photographic manner includes: for each target shooting object, determining the current shooting orientation of the terminal equipment at the relative position corresponding to the target shooting object; for each target shooting object, determining the deviation between the current shooting orientation of the terminal equipment and the target shooting orientation at the relative position; and for each target shooting object, adjusting the display size of the target shooting object in the shooting interface according to the deviation corresponding to the target shooting object.
It is to be understood that, when a plurality of target photographic subjects are provided and a plurality of target photographic subjects are photographed by the portrait adjustment photographing manner, the processes of steps S401 to S403 may be performed for each target photographic subject, that is, the correction may be performed for each target photographic subject to form a final photographed image.
Fig. 10 and 11 are schematic diagrams illustrating comparison between before and after adjustment of a display size of a target photographic object within a photographic interface based on a portrait adjustment shooting mode according to an embodiment of the present application.
As shown in fig. 10 and 11, in the present example, the number of target photographic objects is two, and the occupied area of the face region of each target photographic object within the photographic interface may be adjusted based on the relative position between each target photographic object and the terminal device to obtain a final image.
Through the method and the device, whether the image is shot by a single person or multiple persons, each portrait in the shot image can show a better shooting angle and shooting effect, a good original image base can be provided for image retouching, and image retouching steps can be even omitted, so that the shooting requirements of users are met.
