The unmanned aerial vehicle 20 is provided with an imaging device 30, and the composition processing device 10 can control the unmanned aerial vehicle 20 to automatically drive the imaging device 30 to move according to the difference between the preset target profile and the selected target profile.

Next, referring to fig. 3, fig. 3 shows a schematic flow chart of a composition processing method, where the method may be applied to a composition processing device, where the composition processing device may be communicatively connected to an unmanned aerial vehicle, the unmanned aerial vehicle may be equipped with an imaging device, and may collect images along the way during the movement of the unmanned aerial vehicle, and the composition device may include a display (such as a touch screen) that may provide a display interface. The display can be fixedly arranged on the patterning device or can be detachably arranged on the patterning device. The connection mode of the composition device and the display comprises wired connection or wireless connection. The method comprises the following steps:

in step S101, a screen acquired by an imaging device mounted in the unmanned plane is displayed on a display interface.

In step S102, a selected target contour and a preset target contour are displayed in the display interface, where the selected target contour is a contour of a target object selected in the screen, and the preset target contour has the same shape as the selected target contour and is located at a fixed position on the display interface.

In step S103, according to the difference between the preset target profile and the selected target profile, the unmanned aerial vehicle is controlled to automatically drive the imaging device to move, so that the profile of the target object in the image acquired by the imaging device coincides with the preset target profile.

In this embodiment, the unmanned aerial vehicle does not need to be manually operated by a user, the unmanned aerial vehicle can automatically drive the imaging device to move under the control of the composition device, and in the process that the unmanned aerial vehicle automatically drives the imaging device to move, whether the picture acquired by the imaging device reaches the accurate expected composition can be determined through the superposition degree between the selected target contour and the preset target contour displayed in the display interface, and the picture acquired by the imaging device is determined to reach the accurate expected composition under the condition that the contour of the target object coincides with the preset target contour.

In some embodiments, the composition processing device may receive the frame acquired by the imaging device, and further display the frame acquired by the imaging device on a display interface, so that a user may determine whether the frame meets a user requirement (such as achieving a composition desired by the user).

Illustratively, the composition processing device is preset with a composition mode, and the composition mode can be started in response to a user instruction; in one example, for example, a composition control is provided in the display interface, and the user can operate (such as clicking, long pressing, sliding, etc.) the composition control according to actual needs, so that the composition processing device responds to the triggering operation of the composition control and enters the composition mode.

After entering the composition mode, a user can select a target object to be composed from the picture according to actual needs, and then the display interface can display the outline of the target object (hereinafter referred to as a selected target outline) at the position of the target object. In this embodiment, the selected target outline determined by the shape outline of the target object is displayed on the display interface, and compared with a simple display method of a rectangular frame including the target object, the precise composition effect with extremely small deviation degree can be realized.

In some embodiments, the target object may include at least one of: a target character, a target object, a target graphic, a selected point, a selected line, or a selected area.

For example, the target person or the target object may be obtained by image recognition of the picture by the composition processing apparatus, for example, the composition processing apparatus may prestore reference data of the target person or the target object, the composition processing apparatus may obtain identification data of each object by image recognition of the picture, and the identification data of a plurality of objects may be compared with the reference data of the target person or the target object, thereby determining the target person or the target object and further confirming the target person or the target object by the user. The target person or the target object may be selected by the user directly in the screen, for example, the target object or the target object may be selected by a frame selection operation in the screen. The composition processing means may then determine the selected target contour from the shape contour of the target person or the target object.

By way of example, the target graphic may include a symmetrical graphic and/or a graphic of a designated structure including, but not limited to, a quadrilateral, a heart, a flower, a pentagram, an irregular polygon, or the like. In one example, the target graphic is selected based on a selection frame in the screen, for example, a user may perform a frame selection operation within a certain display range of the screen, and the composition processing apparatus may display the selection frame based on the frame selection operation, and then the graphic in the selection frame is the currently selected target graphic. In another example, to save user operations, the composition processing apparatus may perform shape recognition on the screen to obtain at least one candidate graphic, and may further display the at least one candidate graphic for selection and confirmation by the user, so as to obtain the target graphic selected from the at least one candidate image. The patterning device may then determine the selected target profile based on the shape profile of the target pattern.

For example, the selected point, selected line, and/or selected area may be selected around an object displayed in the screen. Such as a river, road, etc., around which the selected points, selected lines, and/or selected areas may be selected. For example, the user may select a point around the object displayed on the screen, or trace a line segment (selected line) or a closed curve (selected area) according to the actual need. In order to improve the display effect, if the target object is a selected point, the selected target outline displayed in the display interface comprises the display effect of the selected point after thickening; if the target object is a selected line, the selected target outline displayed in the display interface includes: the selected line and the extension line thereof are convenient for a user to know the position of the selected line, and on the other hand, the difference (such as position difference and/or angle difference and the like) between the selected target profile and the preset target profile is also convenient to determine; if the target object is a selected area, the selected target outline displayed in the display interface includes: the closed curve surrounding the selected area is not limited in shape, and it is understood that the selected area may be circular or square.

It can be understood that, in the process of selecting the target object, if the selected object does not meet the requirement, the user can reselect or adjust the selected object so that the composition processing apparatus obtains the final selected target object; for example, the first selected graph does not meet the requirement, and the target graph can be reselected; for example, the selected line or the position of the point does not meet the requirement, and the position of the selected point or the position of the line can be adjusted; also, for example, the size of the selected area may be adjusted to not meet the demand.

After the target object is selected, a preset target contour can be obtained according to the selected target contour corresponding to the target object, and the preset target contour is displayed at a fixed position on the display interface. The preset target contour and the selected target contour have the same shape, but the display size, the display position or the display angle, etc. of the preset target contour and the selected target contour may be the same or different. Wherein the fixed position is a desired composition position of the target object.

In an exemplary embodiment, the screen is displayed in full screen in the display interface; the fixed location may include at least one of: the center point of the display interface, the intersection point of the transverse N-bisector and the longitudinal M-bisector of the display interface, a closed curve, a diagonal line or the transverse N-bisector and/or the longitudinal M-bisector in the display interface; wherein N, M are integers greater than 1. For example, when n=2, the horizontal bisector of the display interface is represented; when m=3, the vertical three-bisector of the display interface is represented. It may be understood that the fixed position may be preset, or may be obtained by a user performing user-defined setting on the composition processing device according to an actual requirement, for example, the user may determine a closed curve or a point at any position of the display interface according to an actual requirement, and then the composition processing device may determine the position where the closed curve or the point is located as the fixed position.

In one example, in order for a user to know a fixed location in a display interface, where to explicitly preset a target profile to display, indication information of the fixed location may be displayed in the display interface, and the indication information may be a line or a point displayed in the display interface indicating the fixed location. For example, referring to fig. 4, in fig. 4, a plurality of fixed positions are indicated by points and lines in the display interface, a A, C, G, I point is an intersection point of a transverse bisector and a longitudinal bisector, B, D, F, H is an intersection point of a transverse bisector and a longitudinal bisector, and E is a center point of a picture, where the preset target profile may be located at one of the fixed positions in A, B, C, D, E, F, G, H, I according to an actual application scenario, or may be located on one of the transverse bisector and the longitudinal bisector.

In another exemplary embodiment, when the screen is not displayed full screen in the display interface, the fixed position may include at least one of: the central point of the display area where the picture is located, the intersection point of the transverse N bisector and the longitudinal M bisector of the display area where the picture is located, the closed curve, the diagonal, or the transverse N bisector and/or the longitudinal M bisector of the display area where the picture is located; wherein N, M are integers greater than 1. For example, when n=2, the horizontal bisector of the display area where the picture is located is indicated; when m=3, the vertical three-bisector of the display area where the picture is located is indicated.

Wherein the patterning device may be provided with a patterning mode. In one example, a plurality of composition modes can be provided, one composition mode corresponds to one fixed position, the fixed positions included in different composition modes are different, and a user can select different composition modes according to actual needs; in another example, a composition mode may be set, where the composition mode includes a plurality of fixed positions, and a user may select one of the fixed positions to perform composition according to actual needs.

In some embodiments, the preset target profile may be obtained from the selected target profile via at least one of: rotate, move or zoom. The difference between the preset target profile and the selected target profile comprises at least one of the following parameter differences: angle difference, position difference, or display size difference.

In an example, the position of the target object is a desired composition position, that is, a fixed position in the display interface, if the display angle of the target object on the fixed position is not satisfied by a user, a preset target contour may be obtained by rotating a selected target contour corresponding to the target object, where the display positions of the preset target contour and the selected target contour are the same, but the display angles are different, and the composition processing device may control the unmanned aerial vehicle to automatically drive the imaging device to move according to the angle difference between the preset target contour and the selected target contour, so that the contour of the target object in the image acquired by the imaging device coincides with the preset target contour.

In one example, the position of the target object is a desired composition position, that is, a fixed position in the display interface, if the user is not satisfied with the display size of the target object on the fixed position, the preset target contour may be obtained by scaling the selected target contour corresponding to the target object, and then the composition processing device may control the unmanned aerial vehicle to automatically drive the imaging device to move according to the size difference between the preset target contour and the selected target contour, so that the contour of the target object in the image acquired by the imaging device coincides with the preset target contour.

In one example, the position of the target object is not a fixed position in the display interface, and the user is not satisfied with the display position of the target object, then a preset target contour displayed on the fixed position may be obtained by moving a selected target contour corresponding to the target object, where the display positions of the preset target contour and the selected target contour are different, and then the composition processing device may control the unmanned aerial vehicle to automatically drive the imaging device to move according to the position difference between the preset target contour and the selected target contour, so that the contour of the target object in the image acquired by the imaging device coincides with the preset target contour.

Of course, at least two operations may be performed on the selected target contour to obtain the preset target contour according to the actual situation, for example, a moving operation and a zooming operation may be performed on the selected target contour to obtain the preset target contour, a rotating operation and a zooming operation may be performed on the selected target contour to obtain the preset target contour, or a moving operation, a rotating operation and a zooming operation may be performed on the selected target contour to obtain the preset target contour, which is not limited in this embodiment.

In an exemplary embodiment, in a case that there are a plurality of fixed positions, the composition processing device may acquire a selected target contour according to a shape contour of the target object after acquiring the selected target object, and superimpose and display the selected target contour on a position where the target object is located, where the selected target contour and the screen are displayed in different layers of the display interface, and the user may drag the selected target contour, if the composition processing device detects that the selected target contour is dragged to the vicinity of the fixed position, a preset target contour may be acquired, such as copying the selected target contour to obtain the preset target contour, and the preset target contour is displayed at the fixed position. In this embodiment, the user may select a fixed position where the composition is desired according to the actual needs, so as to meet the personalized needs of the user.

As a possible implementation manner, if the selected target profile is detected to be dragged to the vicinity of the fixed position for convenience of user operation, the obtained preset target profile can be automatically absorbed to the fixed position without other operations by the user, which is beneficial to reducing operation steps of the user.

When the user drags the selected target outline away from the position of the target object, the selected target outline may still be displayed at the position of the target object, that is, the selected target outline at the position of the target object and the target outline dragged by the user are displayed in the display interface, and the colors of the selected target outline and the target outline may be different, or one of the two outlines is depicted by a solid line and the other is depicted by a dashed line, so as to facilitate the distinction of the user.

In another exemplary embodiment, in the case that there is only one fixed position, the composition processing apparatus may acquire the selected target profile according to the shape profile of the target object after acquiring the selected target object, and if it is detected that the position of the target object is not the fixed position, may copy the selected target profile to obtain a preset target profile, and directly display the preset target profile on the fixed position, and may further perform a rotation process or a scaling process on the preset target profile.

For convenience of user distinction between the selected target profile and the preset target profile, the display colors of the selected target profile and the preset target profile may be different, such as one being a red line and the other being a green line; and/or one of the selected target profile and the preset target profile is a solid line, and the other is a dashed line.

In some scenes, in order to achieve a fully symmetrical fine composition effect, the preset target contour may be symmetrically displayed with the fixed position as a center point, and when the contour of the target object in the image acquired by the imaging device coincides with the preset target contour, a fully symmetrical display effect of the target object on the fixed position may be achieved, so that the requirements of certain high-requirement photographic scenes may be met.

In an example, when the position of the target object is not a fixed position in the display interface, in order to provide a reference for a user, the indication information (lines or points) of the fixed position may also be displayed in a superimposed manner in the image of the imaging device, for example, as shown in fig. 5A, and the indication information of the fixed position, for example, the composition points and/or the composition lines as shown in fig. 4, may be displayed in a superimposed manner in the image acquired by the imaging device, so as to provide a reference for the user. Under the condition that a plurality of fixed positions exist, a user can select the fixed position expected by the composition according to the actual application scene.

For example, in fig. 5A, assuming that the selected target object is an attic building in a screen, the screen is displayed in full screen on a display interface, and the fixed position determined by the user is the center of the display interface, as shown in fig. 5B, the selected target contour 100 may be displayed at the position where the target object is located, and a preset target contour 200 may be displayed at the center of the display interface, where the preset target contour 200 is obtained by moving the selected target contour 100, for example, if it is detected that the user drags the selected target contour 100 to the vicinity of the center point E, the composition processing apparatus may copy the selected target contour 100 to obtain the preset target contour 200, and automatically adsorb the copied preset target contour 200 to the center point E. Of course, if only one fixed position is assumed to be the center of the display interface, the preset target outline 200 may be directly displayed at the center point of the display interface, and no indication information of the fixed position is displayed. Of course, in addition to moving the selected target profile 100, a rotation or scaling operation may be performed on the selected target profile 100.

In another example, as shown in fig. 6, the target object is a selected line, the selected line is selected around the highway, and considering that the line selected by the user may be short, an extension line is displayed in addition to the selected line, and the selected target contour displayed in the display interface includes: the selected line and the extension line thereof are convenient for a user to know the position of the selected line, and on the other hand, the position difference and/or the angle difference between the selected target profile and the preset target profile are also convenient to determine. Assuming that the fixed position is a position where a diagonal line of the display interface is located, as shown in fig. 6, the selected target profile 100 and the preset target profile 200 may be displayed on the display interface, and in order to distinguish the two, the selected target profile 100 is a solid line, and the preset target profile 200 is a dotted line.

In some embodiments, after the preset target contour and the selected target contour are acquired, the composition processing device may control the unmanned aerial vehicle to automatically drive the imaging device to move according to a difference between the preset target contour and the selected target contour, so that the contour of the target object in the picture acquired by the imaging device coincides with the preset target contour. In the process that the unmanned aerial vehicle drives the imaging device to move, a user can see that the target object in the real-time picture acquired by the imaging device is gradually close to a preset target contour at a fixed position until the contour of the target object coincides with the preset target contour, so that an automatic fine composition effect is realized.

In some possible implementations, the composition processing device may send a control instruction to the unmanned aerial vehicle according to a difference between the preset target profile and the selected target profile, so as to control the unmanned aerial vehicle to automatically drive the imaging device to move.

In an example, for example, on the basis of the embodiment shown in fig. 5A and fig. 5B, the composition processing device may control the unmanned aerial vehicle to automatically drive the imaging device to move according to the difference between the preset target profile and the selected target profile, so as to obtain an effect that the profile of the target object in the image acquired by the imaging device shown in fig. 5C coincides with the preset target profile.

In some embodiments, it is contemplated that the preset target profile may be obtained from the selected target profile via at least one of: and rotating, moving or zooming, wherein one or more corresponding points are arranged between the preset target contour and the selected target contour, and at least one parameter difference between the preset target contour and the selected target contour can be determined according to the position relation between the one or more corresponding points. The positional relationship between the one or more corresponding points includes a two-dimensional positional relationship and/or a three-dimensional positional relationship between the one or more corresponding points, where the two-dimensional positional relationship refers to a positional relationship between display positions of the one or more corresponding points on a display interface (two-dimensional space), and the three-dimensional positional relationship refers to a positional relationship between three-dimensional spatial position coordinates corresponding to the one or more corresponding points.

Illustratively, the one or more corresponding points include points located within the preset target profile and within the selected target profile, respectively, and/or points located on the preset target profile and on the selected target profile, respectively.

For example, when the preset target profile is obtained by moving the selected target profile, the corresponding points may include a center point in the preset target profile and a center point in the selected target profile, and a position difference between the preset target profile and the selected target profile may be determined according to a position relationship between the center point in the preset target profile and the center point in the selected target profile; of course, the position difference between the two may be determined by other corresponding points, which are not limited in this embodiment, for example, the vertex of the preset target contour and the vertex of the selected target contour, or the midpoint of a certain side of the preset target contour and the midpoint of a certain side point corresponding to the selected target contour, or the like.

For example, when the preset target profile is obtained by rotating the selected target profile, the corresponding points may include a plurality of points respectively located on the preset target profile and the selected target profile, and the angular difference between the preset target profile and the selected target profile may be determined according to the positional relationship of the plurality of points respectively located on the preset target profile and the selected target profile.

For example, when the preset target contour is obtained by scaling the selected target contour, the corresponding points may be a plurality of points for constructing the preset target contour and a plurality of points for constructing the selected target contour, and a display size difference between the preset target contour and the selected target contour may be determined according to a positional relationship therebetween.

In an exemplary embodiment, the composition processing device may determine a movement direction of the unmanned aerial vehicle according to a difference between the preset target contour and the selected target contour, so that the unmanned aerial vehicle automatically drives the image capturing device to move in the movement direction until the contour of the target object in the real-time picture acquired by the imaging device coincides with the preset target contour. In this embodiment, the unmanned aerial vehicle is automatically controlled according to the difference between the preset target profile and the selected target profile, so as to achieve the purpose that the profile of the target object in the real-time picture acquired by the imaging device coincides with the preset target profile, and achieve an automatic fine patterning effect.

In some scenes, considering that under the condition that the unmanned aerial vehicle needs to move towards multiple directions, the motors need to be controlled to operate in a coordinated manner, the power consumption is relatively high, in order to reduce the power consumption of the unmanned aerial vehicle, the moving direction can comprise the translational direction of the unmanned aerial vehicle under the condition that the flying height, the direction and the acquisition angle of the imaging device are unchanged, namely, the unmanned aerial vehicle only needs to perform translational movement, and the unmanned aerial vehicle does not need to adjust the other components, so that the unmanned aerial vehicle is further saved, the expected composition is achieved with the minimum loss, the cruising ability of the unmanned aerial vehicle is improved, and only the unmanned aerial vehicle performs translational movement, the flying height, the direction and the acquisition angle of the imaging device of the unmanned aerial vehicle are unchanged, in this case, the difference (such as the difference of the sizes, the differences of the acquisition angles and the like) of the same target objects (such as scenes, characters, the target graphics, selected points, lines, areas and the like) in different images are small or the images can be ignored, and the position change of the target objects in the images is achieved under the condition that the size is unchanged.

Illustratively, the difference between the preset target profile and the selected target profile comprises at least one of the following parameter differences: angle differences, position differences, or display size differences. When the preset target profile is obtained through rotation according to the selected target profile, the unmanned aerial vehicle can be controlled to automatically drive the imaging device to move according to the angle difference between the preset target profile and the selected target profile so as to adjust the direction of the imaging device, and in the moving process of the imaging device, a user can see that the target object in a real-time picture acquired by the imaging device gradually rotates until the profile of the target object coincides with the preset target profile.

When the preset target contour is obtained through movement according to the selected target contour, the unmanned aerial vehicle can be controlled to automatically drive the imaging device to move according to the position difference between the preset target contour and the selected target contour so as to adjust the position of the target object in the picture acquired by the imaging device, and in the moving process of the imaging device, a user can see that the target object in the real-time picture acquired by the imaging device gradually moves until the contour of the target object coincides with the preset target contour.

When the preset target contour is obtained by scaling according to the selected target contour, the unmanned aerial vehicle can be controlled to automatically drive the imaging device to move according to the size display size difference between the preset target contour and the selected target contour so as to adjust the distance between the imaging device and the target object, and in the moving process of the imaging device, a user can see that the display size of the target object in a real-time picture acquired by the imaging device is gradually changed until the contour of the target object coincides with the preset target contour.

In another exemplary embodiment, in the case that the unmanned aerial vehicle is provided with a cradle head, the imaging device is connected with the cradle head, and considering that the power consumption of the whole movement of the unmanned aerial vehicle is higher, the unmanned aerial vehicle can be considered to keep the posture unchanged under the condition that the rotation limiting condition of the cradle head allows, and only the cradle head is controlled to rotate to automatically drive the imaging device to move, so that the outline of the target object in the picture acquired by the imaging device coincides with the preset target outline. For example, the adjustment amount of the pan-tilt may be determined according to the difference between the preset target profile and the selected target profile, where the adjustment amount may include a movement amount of the pan-tilt in the determined movement direction, so that the unmanned aerial vehicle maintains a constant posture, and the pan-tilt is automatically controlled to perform adjustment according to the adjustment amount, so as to drive the imaging device to move, so that the profile of the target object in the image acquired by the imaging device coincides with the preset target profile. In this embodiment, under the condition that the rotation limiting condition of the pan-tilt allows, the unmanned aerial vehicle can be considered to keep the posture unchanged, and only the pan-tilt is controlled to rotate, so that the power consumption of the unmanned aerial vehicle is reduced.

Of course, when only the cradle head can not achieve the effect of overlapping the contour of the target object with the preset target contour in the frame acquired by the imaging device, the unmanned aerial vehicle can also be adjusted to control the unmanned aerial vehicle to move, for example, a first adjustment amount of the cradle head and a second adjustment amount of the unmanned aerial vehicle can be determined according to the difference between the preset target contour and the selected target contour, the first adjustment amount comprises the movement amount of the cradle head in the determined movement direction, the second adjustment amount comprises the movement amount of the unmanned aerial vehicle in the determined movement direction, the cradle head is automatically controlled to adjust according to the first adjustment amount, and the unmanned aerial vehicle is automatically controlled to adjust according to the second adjustment amount, so that the imaging device is driven to move, and the contour of the target object in the frame acquired by the imaging device overlaps with the preset target contour.

In an exemplary embodiment, referring to FIG. 7, FIG. 7 shows a schematic flow diagram of another patterning device:

in step S31, a screen acquired by an imaging device mounted on the unmanned aerial vehicle and indication information of a fixed position, for example, a horizontal-vertical bisector, a horizontal-vertical trisection, a diagonal line, and an intersection of these lines, which is a displayed point or line, are displayed on the display interface.

In step S321, it is determined whether the user selects the target graphic from the frame, if so, step S33 is performed; if not, step S322 is performed.

In step S322, it is identified whether the target graphic exists in the screen, if so, step S33 is executed, and if not, step S321 is executed.

In step S33, a selected target contour of the target graphic is displayed.

In step S34, if it is detected that the selected target profile is dragged to the vicinity of the fixed position, a preset target profile is acquired, and the preset target profile is displayed at the fixed position. For example, the preset target profile is symmetrically placed with the fixed position as a center.

In step S35, according to the difference between the preset target profile and the selected target profile, a translation direction of the unmanned aerial vehicle under the conditions that the flying height, the direction and the acquisition angle of the imaging device are unchanged is determined, and the unmanned aerial vehicle is controlled to automatically drive the imaging device to translate towards the translation direction.

In step S36, a frame acquired by the imaging device is received and displayed.

In step S37, it is determined whether the contour of the target object in the screen coincides with the preset target contour; if so, executing step S38; if not, step S36 is performed.

In step S38, the unmanned aerial vehicle is controlled to stop moving, and a target picture in which the outline of the target object coincides with the preset target outline is displayed.
