Wherein the first mode is one of a following mode and a target tracking mode, and the second mode is the other of the following mode and the target tracking mode.
For example, if the first mode is a following mode, the second mode is a target tracking mode; or, if the first mode is a target tracking mode, the second mode is a following mode.
Under the first mode of the handheld cloud deck, when the shooting device is controlled to collect video information, whether a first mode switching instruction is received or not can be detected, so that mode switching can be carried out according to the first mode switching instruction. Such as switching the following mode of the handheld pan/tilt head to a target tracking mode.
In one embodiment, the detecting whether the first mode switching instruction is received specifically includes: detecting whether a user operates a first control element on the handheld cloud deck; generating the first mode switching instruction when detecting that a user operates a first control piece on the handheld cloud deck. Wherein the first control member comprises a key, a trigger or a knob and the like.
For example, in the following mode of the handheld cradle head, when the shooting device is controlled to capture a video, and it is detected that a user operates the first control element, for example, a trigger is pulled by the user, a first mode switching instruction is generated according to the trigger of the user operating the first control element.
From this can realize one-hand operation, can trigger the target and track, for the traditional trigger mode of holding handheld cloud platform frame on one hand, can reduce the shake of cloud platform relatively, prevent the shake of picture, and then can shoot the stable picture of high accuracy to user's experience has been improved.
Wherein, when utilizing the first control piece of handheld cloud platform to follow mode and the switching of target tracking mode, optional, the shooting method based on handheld cloud platform specifically can be for: controlling the shooting device to collect image information in a first mode of the handheld cloud deck; if the first operation of a user on a first control piece of the handheld cloud deck is detected, generating a first mode switching instruction according to the first operation; and if a first mode switching instruction is detected, switching the handheld cloud deck from the first mode to a second mode, and controlling the shooting device to continue to acquire image information under the second mode of the handheld cloud deck.
The first control element of the handheld holder is subjected to a first operation, for example, the first control element is a trigger, the first operation is that a user pulls the trigger once or pulls the trigger twice continuously, and the like, but other operation modes of the trigger can be adopted. Mode switching is realized through a trigger, and therefore one-hand operation is realized.
The acquisition of the image information can be the acquisition of video information, and can also be the real-time output of live image transmission pictures.
In one embodiment, the detecting whether the first mode switching instruction is received specifically includes: detecting whether the collected video information contains a first preset action gesture; and generating the first mode switching instruction when the video information is detected to contain a first preset action gesture.
The first preset action gesture is a prestored action gesture of the user and comprises a gesture, a hand action form, a body posture or other action forms and the like. For example, the first preset action gesture is an "OK" gesture or a track of a circle drawn by a finger.
Therefore, the shooting device can not be touched, the triggering target tracking can be realized, the shaking of the picture caused by the shaking of the holder can be relatively reduced compared with the traditional triggering mode that a picture frame of the holder is held by one hand, the remote control of the holder can be realized, and then the high-precision stable picture can be shot and the user experience is improved.
In another embodiment, the detecting whether the first mode switching instruction is received specifically includes: detecting whether a user carries out first preset operation on an interactive interface of a first device or not; and generating the first mode switching instruction when detecting that a user carries out first preset operation on an interactive interface of the first device.
Wherein the first device comprises the handheld cloud deck, the shooting device or a first control device of the handheld cloud deck. The interactive interface of the first device may be a software interactive interface displayed on a display screen, or may also be a physical interactive device, such as a touch key, and the software interactive interface is taken as an example for description in this embodiment. The first control device may be a remote control device of the handheld cradle head, such as a remote controller, a smart phone, and the like. The mode switching or the selection of the target object can be quickly performed by operating the interactive interface of the first device to generate the first mode switching instruction.
The first preset operation may include a frame selection operation, a click operation, a sliding operation, a touch operation, or the like.
It is to be understood that a frame selection operation, a click operation, a slide operation, or a touch operation may be an operation on a target object displayed in the display screen. The target object is a shooting subject and comprises a person, an animal, a scene or other objects.
For example, a first mode switching instruction is detected, and the handheld tripod head is switched from the following mode to the target tracking mode according to the first mode switching instruction. And controlling the shooting device to continue to collect video information, such as continue to shoot videos, in the target tracking mode of the handheld holder. When the following mode is switched to the target tracking mode, the video information collected by the shooting device in the following mode of the handheld holder comprises a target object for tracking shooting. In this way, smooth transition of the shooting screen can be realized when the mode is switched.
It will be appreciated that the handheld pan/tilt head may also be switched from the target tracking mode to the follow-up mode. In one embodiment, controlling the shooting device to continue to collect video information specifically includes: and controlling the shooting device to continue to collect the video information along the first position. Wherein the first position is a position of the photographing apparatus when the handheld tripod head is switched from the first mode to the second mode.
For example, the first position is a position of the photographing apparatus when the handheld tripod head switches from the following mode to the target tracking mode, that is, a position of the photographing apparatus in the following mode at a switching time point. And when the target tracking mode is switched, continuously acquiring the video information by adopting the target tracking mode and still using the first position. Therefore, the sudden change of the picture of the video information can not be caused.
In one embodiment, during the collection process of the video information, whether an instruction for ending the collection of the video information is received or not can be detected; and if an instruction for finishing video information acquisition is received, controlling the shooting device to continuously acquire the video information with preset time duration in the following mode of the handheld cloud deck, and finishing the acquisition of the video information when the preset time duration is exceeded. When receiving an instruction for finishing video information acquisition, the handheld holder can be in a following mode or a target tracking mode, but the video information acquisition is finished in the following mode. Therefore, when the instruction for finishing video information acquisition is detected in the target tracking mode, the video shooting is finished in the following mode, so that sudden change of the video caused by disappearance of the target object can be prevented, and the fluency and stability of the video shooting are further improved.
The instruction for ending the video information collection can be generated by a first control element, such as detecting that a user operates the first control element, and generating the instruction for ending the video information collection. In the actual implementation process, the operation mode of triggering and generating the instruction for ending the video information acquisition is different from the operation mode of triggering and generating the first mode switching instruction.
It is understood that the instruction for ending the video information collection may also be implemented in other manners, such as detecting whether the image in the video information includes a preset action gesture.
The shooting method of the embodiment controls the shooting device to collect video information in the first mode of the handheld cloud deck; when a first mode switching instruction generated by different trigger modes is detected, the handheld cloud deck is switched from the first mode to a second mode, and the shooting device is controlled to continue to collect video information under the second mode of the handheld cloud deck, wherein the first mode is one of a following mode and a target tracking mode, and the second mode is the other mode. Therefore, smooth transition of the following mode and the target tracking mode in the shooting process is realized, the problem that the following mode and the target tracking mode cannot be used in a mixed mode in the same video shooting is solved, and the fluency and the stability of the video shooting are improved.
Referring to fig. 3, fig. 3 is a schematic flowchart illustrating steps of a shooting method based on a handheld pan/tilt according to another embodiment of the present application.
As shown in fig. 3, the handheld tripod head based photographing method includes steps S301 to S303.
S301, controlling the shooting device to collect video information in a first mode of the handheld holder, wherein the first mode is a following mode.
S302, if a first mode switching instruction is detected, switching the handheld holder from the first mode to a second mode, wherein the second mode is a target tracking mode.
And S303, controlling the shooting device to collect video information containing the target object through the handheld cradle head according to the preset composition position of the target object tracked by the handheld cradle head in the video information in the target tracking mode of the handheld cradle head.
For example, the first mode is taken as a following mode, and the second mode is taken as a target tracking mode.
And the preset composition position is the position of the target object in the video information when the handheld cloud deck is switched to the target tracking mode. Namely, the original position is kept to compose the picture of the target object, and the original position is the position of the target object in the video information when the mode is switched.
For example, as shown in fig. 3a, when the target tracking mode is switched to, the position of the target object 20 in the video information 130 is an upper left corner, and the target object is composed by keeping the original position, then the preset composition position is also the upper left corner. Namely, the currently used composition is the upper left corner of the video information acquired by the target object, and the shooting device is controlled by the handheld cradle head to acquire the video information containing the target object according to the composition.
Of course, the preset composition position is different from the position of the target object in the video information when the handheld tripod head is switched to the target tracking mode, that is, the position of the target object in the video information when the handheld tripod head is switched to the target tracking mode is changed. Such as placing the target object in the center of the screen, or placing the target object in a preset position in the screen, where the preset position is defined by the photographer.
For example, if the position of the target object 20 in the video information 130 when the target tracking mode is switched to is the upper left corner, the position of the target object in the video information when the target tracking mode is switched to is changed. As shown in fig. 3b, the target object 20 is placed in the center of the video information 130; alternatively, as shown in fig. 3c, the target object 20 is placed in the upper right corner of the video information 130.
In one embodiment, in the process of controlling the shooting device to collect video information containing the target object through the handheld cloud deck according to a preset composition position, whether a control instruction for controlling the motion of the cloud deck is received or not is detected; if a control instruction for controlling the motion of the holder is detected, controlling the motion of the holder according to the control instruction so as to change a preset composition position of the target object in the video information; and controlling the shooting device to collect video information containing the target object through the handheld cloud deck according to the changed preset composition position.
For example, in the process of controlling the shooting device to acquire video information including the target object through the handheld pan/tilt according to the preset composition position (picture center) in fig. 3b, if a control instruction for controlling the pan/tilt motion by operating the rocker by the user is detected, the pan/tilt motion is slowly controlled according to the control instruction to move the target object to the position (picture upper right corner) in fig. 3c, so as to obtain a new composition. And controlling the shooting device to collect the video information containing the target object through the handheld cloud deck according to the new composition, namely the changed preset composition position.
In the target tracking shooting, the cradle head is controlled up, down, left and right through a rocker on the handheld part to change the position of a tracked target object in a picture corresponding to video information so as to realize a new composition, and the target object is subjected to tracking shooting through the new composition (the changed preset composition position). Therefore, an interactive mode of recomposing is realized in the target tracking process, and the shooting experience of a user is further improved.
In the embodiment of the present application, three ways of generating a control command for controlling the motion of the pan/tilt head include:
in a first mode, the control instruction is generated when the user is detected to operate the second control piece on the handheld cloud deck. The second control member comprises a key, a trigger or a knob and the like. The second control part can be the same as or different from the first control part.
When the second control element is the same as the first control element, different instructions can be generated by adopting different operation modes, for example, the second control element and the first control element are both triggers, a trigger is pulled once to generate a mode switching instruction, and a trigger is pulled twice continuously to generate the control instruction.
When the second control piece is different from the first control piece, for example, the first control piece is a trigger, and the second control piece is a key, the trigger is pulled to trigger and generate a mode switching instruction, and the key is pressed to trigger and generate the control instruction.

In one embodiment, a pre-warning frame is set in the collected video information in advance, and the size of the pre-warning frame is equal to or smaller than the size of a display screen of the shooting device. Due to the fact that different composition modes are achieved, when video information containing target objects is collected, the target objects are prone to being lost. Before the video information containing the target object is collected, the early warning box is also used for preventing the target object from being lost.
The specific using process is as follows: detecting whether the target object is located in a preset early warning frame in the video information; and if the target object is located in the preset early warning frame, continuing to execute the step of controlling the shooting device to acquire video information containing the target object through the handheld cloud deck according to the changed preset composition position.
In addition, if the target object exceeds the preset early warning frame, the cradle head is controlled to move so as to move the target object into the preset early warning frame. Specifically, the cradle head is controlled to move at a preset speed so as to stably move the target object into the preset early warning frame.
In one embodiment, in order to quickly move the target object into the early warning frame, the target object is moved into the early warning frame by using the azimuth information, specifically: acquiring azimuth information of a part of the target object beyond the preset early warning frame; and controlling the holder to move according to the azimuth information so as to move the target object into the early warning frame.
For example, as shown in fig. 5, if it is detected that the target object 20 exceeds the preset warning frame 131, the target object is located on the left side of the warning frame 131, and the left side is the azimuth information. Thereby, the yaw axis can be quickly determined and adjusted according to the azimuth information so as to move the target object into the early warning frame.
The shooting method of the embodiment is embodied in that in the process of acquiring video information, if a target tracking mode is adopted, the target object can be recomposed, namely the picture position of the target object in the video information is changed, so that different shooting effects are achieved.
Referring to fig. 5, fig. 5 is a flowchart illustrating steps of a shooting method based on a handheld pan/tilt according to another embodiment of the present application.
As shown in fig. 5, the handheld tripod head based photographing method includes steps S401 to S403.
S401, controlling the shooting device to collect video information in the first mode of the handheld cloud deck.
S402, if a first mode switching instruction is detected, switching the handheld cloud deck from the first mode to a second mode, and controlling the shooting device to continue to collect video information in the second mode of the handheld cloud deck.
And S403, stopping the shooting device from collecting the video information if an instruction for canceling the second mode is received.
Illustratively, the first mode of the handheld tripod head is a following mode, and the second mode of the handheld tripod head is a target tracking mode.
Specifically, the handheld cloud deck is switched to a target tracking mode from the following mode, and the shooting device is controlled to continue to collect video information in the target tracking mode of the handheld cloud deck.
Specifically, when an instruction for canceling the second mode is received, the shooting device is stopped from collecting video information according to the instruction, and shooting is completed. Wherein generating the instruction to cancel the second mode comprises:
and generating the instruction for canceling the second mode when detecting that the user operates a third control part on the handheld cloud deck.
Wherein the third control comprises a key, a trigger, a knob, or the like. The third control element may be the same as or different from the first control element and the second control element. When the same, different instructions may be generated in different manners of operation.

And when detecting that a user performs a third preset operation on an interactive interface of a third device, generating the instruction for canceling the second mode.
Wherein the third device comprises a third control device of the handheld tripod head, the shooting device or the handheld tripod head. The third control device may be the same as or different from the first control device and the second control device. When the first preset operation is the same as the second preset operation, the third preset operation is different from the first preset operation and the second preset operation.
In one embodiment, if an instruction for canceling the second mode is received, the capturing of the video information by the capturing device is stopped, which may be ending the capturing of the video information or pausing the capturing of the video information.
In an embodiment, if an instruction for canceling the second mode is received, the capturing of the video information may not be stopped, but the handheld cradle head may be switched from the second mode to the first mode, and the capturing device is controlled to continue capturing the video information in the first mode of the handheld cradle head.
Specifically, if an instruction for canceling the second mode is received, the handheld cradle head is switched from the target tracking mode to the following mode, and the shooting device is controlled to continue to collect video information in the following mode of the handheld cradle head.
And when receiving an instruction for canceling the second mode, not immediately stopping controlling the shooting device to collect the video information, but switching the handheld tripod head from the target tracking mode to the following mode, and controlling the shooting device to continue to collect the video information in the following mode of the handheld tripod head.
In one embodiment, in the following mode of the handheld cradle head, the shooting device is controlled to continuously collect video information for a preset time, and the shooting device is controlled to stop collecting video information when the preset time is exceeded. For example, the preset time period is 2 seconds, when the handheld cradle head is switched to the following mode, the shooting device is controlled to continuously collect video information for 2 seconds, and shooting is stopped after 2 seconds. In the shooting process adopting the target tracking mode, if an instruction of canceling the target tracking mode is received, the shooting is not stopped immediately, but the shooting is stopped after the follow-up mode is adopted to continue the shooting, so that the fluency of picture shooting can be further improved.
It should be noted that the command for canceling the second mode may be a trigger generation method of the first mode switching command, but in practical applications, the trigger generation method of the first mode switching command is to be distinguished. The generation manner of the instruction for canceling the second mode also includes various manners.
The shooting method of the embodiment not only realizes smooth transition of the following mode and the target tracking mode in the shooting process, solves the problem that the following mode and the target tracking mode cannot be used in a mixed mode in the same video shooting, improves the fluency and stability of the video shooting, but also enriches the application mode of receiving the instruction for canceling the second mode.
Referring to fig. 6, fig. 6 is a flowchart illustrating steps of a shooting method based on a handheld pan/tilt according to another embodiment of the present application.
As shown in fig. 6, the handheld tripod head based photographing method includes steps S501 to S503.
S501, controlling the shooting device to collect video information in the first mode of the handheld cloud deck.
S502, if a first mode switching instruction is detected, switching the handheld cloud deck from the first mode to a second mode, and controlling the shooting device to continue to collect video information in the second mode of the handheld cloud deck.
And S503, if a second mode switching instruction is detected, controlling the handheld cloud deck or the shooting device to execute preset operation matched with the second mode switching instruction.
Illustratively, the first mode is a follow mode and the second mode is a target tracking mode. And particularly, controlling the shooting device to collect video information in a following mode of the handheld cloud deck. And if a first mode switching instruction is detected, switching the handheld cloud deck from the following mode to a target tracking mode, and controlling the shooting device to continue to collect video information in the target tracking mode of the handheld cloud deck.
However, in practical applications, the trigger generation manner of the first mode switching instruction is to be distinguished from that of the second mode switching instruction. The generation manner of the second mode switching instruction also includes various manners.
The second mode switching instruction is generated in different ways, and correspondingly, the preset operation corresponding to the second mode switching instruction is different.
For example, when the second mode switching instruction is generated in a manner that the user continuously controls a fourth control element on a fourth device, the preset operation is that the handheld tripod head enters a third mode, and the third mode is different from the first mode and the second mode. For example, the third mode is a lock mode.
Wherein the fourth device comprises the handheld cloud deck, the shooting device or a fourth control device of the handheld cloud deck.
Further, when the user releases the operation of the fourth control, the handheld pan/tilt head exits the third mode.
For example, when the second mode switching instruction is generated in a manner that the user controls the fourth control element on the fourth device at one time, the preset operation is that the handheld cradle head enters or exits the following mode; wherein the fourth device comprises the handheld cloud deck, the shooting device or a fourth control device of the handheld cloud deck.
For example, when the second mode switching instruction is generated in a manner that the user continuously controls the fourth control element on the fourth device twice, the preset operation is that the cradle head rotates to a preset position (for example, returns to the center), or the handheld cradle head exits or enters a sleep state; wherein the fourth device comprises the handheld cloud deck, the shooting device or a fourth control device of the handheld cloud deck.
For example, when the second mode switching instruction is generated in a manner that the user controls the fourth control element on the fourth device once and continuously controls the fourth control element, the preset operation is that the cradle head enters a fourth mode, and the fourth mode is different from the first mode and the second mode. For example, the fourth mode is a motion mode. Wherein the fourth device comprises the handheld cloud deck, the shooting device or a fourth control device of the handheld cloud deck. It will be appreciated that the operation of the fourth mode may be during a continuous control of the fourth control, the handheld pan/tilt head exiting the fourth mode when the user releases the operation of the fourth control. Of course, the fourth mode may be started after the fourth control element continues to control for a preset time.
For another example, when the second mode switching instruction is generated in a manner that the user continuously controls the fourth control element on the fourth device three times, the preset operation is to control the shooting device to switch between front shooting and rear shooting, or to control the pan-tilt to rotate, so that the shooting device is switched between two opposite shooting directions; wherein the fourth device comprises the handheld cloud deck, the shooting device or a fourth control device of the handheld cloud deck.
It should be noted that S502 and S503 may occur in a time sequence in a manner shown in the figure, or may occur in another time sequence, where when S503 occurs, if the continuous acquisition of the video information is not affected, the acquisition of the video information may not be interrupted, so as to implement continuous acquisition of the video information in different modes.
The shooting method of the embodiment not only realizes the smooth transition of the following mode and the target tracking mode in the shooting process, solves the problem that the following mode and the target tracking mode cannot be used simultaneously in the same video shooting, and further improves the flow and the stability of the video picture shooting; meanwhile, more mode switching modes are provided in the following mode and target tracking mode shooting processes, and therefore shooting experience of a user is improved.
On the other hand, in the prior art, when the target tracking mode is used for collecting image information, the picture position of a target object for tracking in the image information is often fixed, a user cannot complete a new picture composition in the collection process of the image information in the target tracking mode, and only an initial picture composition mode is adopted, the target object is always placed at a picture fixed position for shooting, and the picture composition requirement of the user may not be met, so that the shooting experience of the user is reduced.
Therefore, the embodiment of the invention provides a shooting method based on a handheld holder, so that in a target tracking mode, a user can adjust the position of a target object in a picture by controlling the holder to form a new composition, and image information is acquired by using the new composition.
Referring to fig. 7, fig. 7 is a flowchart illustrating steps of a shooting method based on a handheld cradle head according to an embodiment of the present application. The shooting method based on the handheld cloud deck can realize recomposition in the process of target tracking so as to improve the shooting experience of a user.
As shown in fig. 7, the handheld tripod head based photographing method includes steps S601 to S603.

And S602, if a control instruction for controlling the movement of the holder is received, controlling the movement of the holder according to the control instruction so as to change the preset composition position of the target object in the image information acquired by the shooting device.
And S603, controlling the shooting device to carry out tracking shooting on the target object according to the changed preset composition position.
Specifically, the target tracking mode is turned on, and the mode can be switched from other modes to the target tracking mode, such as the following mode to the target tracking mode. And when the handheld cloud deck is in a target tracking mode, controlling the shooting device to carry out tracking shooting on a target object.

The preset composition position can be defined according to the requirement of the user, and the original position can be maintained. Therefore, composition is realized in the target tracking shooting process, the interaction mode is increased, and the user experience is improved.
For example, the preset composition position is an initial position of the target object in the image information when the handheld tripod head enters the target tracking mode. Namely, the original position of the target object in the acquired image information is kept to compose the target object, and the preset composition position is obtained.
For another example, the preset composition position is different from an initial position of the target object in the image information when the handheld tripod head enters the target tracking mode. Different from the initial position, the target object may be placed in the center or other position of the corresponding frame of the image information, i.e. the user may define the corresponding position himself.
Further, the control instruction for controlling the motion of the pan/tilt head can control the motion of the pan/tilt head to adjust the relative motion of the shooting device, so as to change the preset composition position of the target object in the image information acquired by the shooting device.
Illustratively, the manner of generating the control instruction for controlling the motion of the pan/tilt head includes:
and generating the control instruction when detecting that a user operates a second control piece on the handheld cloud deck.
Wherein the second control member comprises a key, a trigger, a knob or the like. The second control member may be the same as or different from the first control member. When the two control elements are the same, different instructions can be generated by adopting different operation modes, for example, the second control element and the first control element are both triggers, the trigger is pulled once to generate a mode switching instruction, and the trigger is pulled twice continuously to generate the control instruction; and when the two control parts are different, for example, the first control part is a trigger, and the second control part is a key, pulling the trigger to trigger generation of a mode switching instruction, and pressing the key to trigger generation of the control instruction.
And when the image information is detected to contain a second preset action gesture, generating the control command.
The second preset action gesture is a pre-stored action gesture of the user, and comprises a gesture, a hand action form or other action forms.

And generating the control instruction when detecting that the user carries out second preset operation on the interactive interface of the second device.
Wherein the second device comprises the handheld cloud deck, the shooting device or a second control device of the handheld cloud deck. The second device may be the same as or different from the first device. The second preset operation is different from the first preset operation when the second device may be the same as the first device. For example, the first preset operation is a single click operation, and the second preset operation is a continuous click operation.
In one embodiment, a warning frame may be set in advance in the acquired image information, and the size of the warning frame is equal to or smaller than the size of the display screen of the shooting device. Due to the fact that different composition modes are achieved, when image information containing the target object is collected, the target object is prone to be lost. Before image information containing the target object is acquired according to the changed preset composition position, the early warning frame is used for preventing the target object from being lost.
The specific using process is as follows: detecting whether the target object is located in a preset early warning frame in the image information; and if the target object is located in the preset early warning frame, continuing to execute the step of controlling the shooting device to acquire the image information containing the target object through the handheld cloud deck according to the changed preset composition position.
In addition, if the target object exceeds the preset early warning frame, the cradle head is controlled to move so as to move the target object into the preset early warning frame. Specifically, the cradle head is controlled to move at a preset speed so as to stably move the target object into the preset early warning frame.
In one embodiment, in order to quickly move the target object into the early warning frame, the target object is moved into the early warning frame by using the azimuth information, specifically: acquiring azimuth information of a part of the target object beyond the preset early warning frame; and controlling the holder to move according to the azimuth information so as to move the target object into the early warning frame.
Further, in the target tracking shooting, a new composition, that is, a changed preset composition position, is realized by changing the position of the tracked target object in the picture corresponding to the image information, and the target object is subjected to tracking shooting by the new composition (the changed preset composition position). Therefore, an interactive mode of recomposing is realized in the target tracking process, and the shooting experience of a user is further improved.
In one embodiment, when the shooting device is controlled to perform tracking shooting on the target object, if an instruction for canceling the target tracking mode is received, the shooting device is stopped from acquiring image information.
