Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

The handheld cloud platform can carry and carry shooting equipment, and this handheld cloud platform can include cloud platform and base, and this cloud platform and base are connected, and this cloud platform is used for bearing shooting equipment, and this base specifically can be the handle. The shooting device may specifically be a device or apparatus having a shooting function, such as a camera or a video camera.

In general, the handheld pan/tilt head is equipped with two motors, as shown in fig. 1, a motor 1 is used for controlling the shooting device to zoom, and a motor 2 is used for controlling the shooting device to follow the focus. In addition, the motor 1 is connected with the focus following wheel 1, and the motor 2 is connected with the focus following wheel 2. Follow focus wheel 1 pivoted in-process and drive motor 1 and rotate, motor 1 is connected with the ring that zooms of this shooting equipment, thereby this motor 1 can drive this ring that zooms and rotate and make this shooting equipment zoom. In a similar way, the motor 2 is connected with the focus ring of the shooting device, and the motor 2 can drive the focus ring to rotate so that the shooting device can focus. That is to say, in order to control this shooting equipment to zoom and follow focus, this handheld cloud platform is provided with two motors usually, and the load of motor is great to the load that leads to this handheld cloud platform is heavier, and just there is the load sense when this handheld cloud platform of user handheld, the handheld cloud platform of user's control of not being convenient for.

In order to solve the above problem, an embodiment of the present invention provides a control method of a photographing apparatus. As shown in fig. 2, in this embodiment, the shooting device is mounted on a handheld tripod head 11, the handheld tripod head 11 is mounted with a motor, the motor can be connected to a zoom ring of the shooting device, for example, the motor can be connected to the zoom ring of the shooting device in an engaging manner, the motor drives the zoom ring to rotate when rotating so as to control the shooting device to zoom, and the handheld tripod head is connected to the shooting device through a control line. The control line is for example a shutter release. The type of shutter release is not limited herein, and the shutter release may be, for example, a Universal Serial Bus (USB).

In addition, the handheld cloud deck further comprises a control device, and the control device can be specifically a device capable of controlling the shooting equipment to follow focus, such as a focus following controller and a shutter controller.

It is understood that zooming refers to changing the focal length of a lens to change the angle of view of shooting, that is, generally to zoom a subject closer or farther. The focus tracking is to make the subject image clearly by changing the focus, and usually to make the subject image clearly on the negative by adjusting the distance between the lens and the negative.

In addition, as shown in fig. 2, the handheld cloud deck 11 may further communicate with a control terminal 12, where the control terminal may specifically be a remote controller, a smart phone, a tablet computer, and the like. The control terminal can be installed with an Application program (APP) for controlling the handheld cradle head. The present embodiment does not limit the communication method between the handheld cradle head and the control terminal, and may be, for example, a wireless communication method or a wired communication method.

Fig. 3 is a flowchart of a control method of a shooting device according to an embodiment of the present invention. As shown in fig. 3, the method in this embodiment may include:

and S301, acquiring a focus following control instruction.

The execution subject of the method of the present embodiment may be the control device as described above. Specifically, the control device can generate a focus following control instruction, or the control device can receive the focus following control instruction sent by the control terminal through the communication interface or the wireless communication module of the handheld cradle head. The focus following control instruction is used for controlling the shooting device to carry out focus following.

Step S302, the focus following control instruction is sent to the shooting device through the control line, and the focus following control instruction is used for controlling the shooting device to carry out focus following.

After the control device obtains the focus following control instruction, the control device can send the focus following control instruction to the shooting device through a control line. And after the shooting equipment receives the focus following control instruction, controlling the lens to follow the focus.

Optionally, the handheld cloud platform is connected with the focus wheel. As shown in fig. 2, the handheld tripod head 11 is further connected to a focus following wheel, which may be an external accessory of the handheld tripod head. In other embodiments, the tracking wheel may also be integrated into the handheld pan/tilt head.

In this embodiment, the tracking wheel may be electrically connected to the motor or to the control device. Optionally, when the operating condition of following the burnt wheel is control when following the focus, follow the burnt wheel with controlling means in the handheld cloud platform is electric to be connected, when the operating condition of following the burnt wheel is control and zooms, follow the burnt wheel with the motor electricity is connected.

In one possible implementation, as shown in fig. 4, the focus wheel is electrically connected to the handheld cradle head through a metal contact 41, and the metal contact 41 is electrically connected to a control device in the handheld cradle head. The control device can be electrically connected with the motor and the shooting equipment respectively in a wired mode. Specifically, when the working state of the focus following wheel is to control zooming, the rotation of the focus following wheel triggers the control device to generate a zooming control instruction, and further, the control device can send the zooming control instruction to the motor in a wired manner, so that the motor rotates. The motor can drive the zooming ring of the shooting equipment to rotate together in the rotating process, so that the shooting equipment is controlled to zoom. When the working state of the focus following wheel is to control focus following, the rotation of the focus following wheel triggers the control device to generate a focus following control instruction, and further, the control device can send the focus following control instruction to the shooting equipment in a wired mode, so that the shooting equipment is controlled to carry out focus following.

Specifically, the control device in the handheld cloud deck can be respectively connected with the shooting equipment and the motor through control lines. The shooting device and the motor can respectively correspond to different identification information IDs, and the working state of the focus wheel can be switched through a mode switching key on the focus wheel, or the working state of the focus wheel can be switched through a mode switching instruction sent by the control terminal 12. Further, the control means may generate a follow-up control instruction based on the mode switching instruction and transmit it to the photographing device having the corresponding identification information, or generate an instruction to control the rotation of the motor and transmit it to the motor having the corresponding identification information.

In another possible implementation manner, the focus following wheel and the motor may be respectively provided with a wireless communication module, and when the focus following wheel is connected to the motor, the focus following wheel and the motor may be wirelessly connected, for example, as shown in fig. 2, when the working state of the focus following wheel is to control zooming, the focus following wheel may generate a zooming control instruction when rotating, and send the zooming control instruction to the motor in a wireless manner, and the motor rotates according to the zooming control instruction and drives a zooming ring of the shooting device to rotate, thereby controlling the shooting device to zoom. When the focus following wheel is connected with the control device, the focus following wheel and the control device can be in wireless connection or in wired connection. The manner of connecting the focus following wheel and the control device by wire is specifically shown in fig. 4, and the manner of connecting the focus following wheel and the control device by wireless is taken as an example for illustrative explanation. Specifically, when the working state of the focus following wheel is to control focus following, the focus following wheel can generate a focus following control instruction during rotation, and the focus following control instruction is sent to the control device in a wireless manner, and the control device further controls the shooting device to carry out focus following according to the focus following control instruction. Or, when the working state of the focus following wheel is to control focus following, the focus following wheel can send the rotation speed of the focus following wheel to the control device in real time or periodically when the focus following wheel rotates, and the control device can generate a focus following control instruction according to the rotation speed of the focus following wheel and control the shooting device to carry out focus following according to the focus following control instruction.

It can be seen that the operating state of the focus wheel is different when the focus wheel is electrically connected to the motor or the control device. For example, when the focus wheel is electrically connected to a motor, the photographing apparatus may perform zooming in a state in which the focus wheel operates to control zooming. When the focus following wheel is electrically connected with the control device, the shooting device can carry out focus following, and in the state, the working state of the focus following wheel is the control focus following.

That is, the tracking wheel may switch from controlling focus to controlling zoom, or from controlling zoom to controlling focus. The specific switching modes may be as follows:

in one possible mode, the focus following wheel is provided with a mode switching key, and the mode switching key is used for controlling the working state of the focus following wheel to switch between focus following control and zoom control.

For example, as shown in fig. 2, a mode switch button may be disposed on the focus wheel, when the mode switch button is turned on, the focus wheel is electrically connected to the motor, and the operating state of the focus wheel is to control zooming. When the mode switching key is closed, the focus following wheel is electrically connected with the control device, and the working state of the focus following wheel is to control focus following. Or when the mode switching key is closed, the focus following wheel is electrically connected with the motor, and the working state of the focus following wheel is to control zooming. When the mode switching key is turned on, the focus following wheel is electrically connected with the control device, and the working state of the focus following wheel is to control focus following. That is, the mode switch button has at least two states, so that one state of the mode switch button can correspond to an operating state of the focusing wheel.

Taking fig. 4 as an example, if the mode switching button on the focus wheel is in the a state, the operation state of the focus wheel is to control zooming. When the mode switching key on the focus following wheel is in the B state, the working state of the focus following wheel is to control focus following. Specifically, when the mode switching key is changed from the state a to the state B, the control device may be triggered to generate a mode switching instruction, and when the focus following wheel rotates, the control device may be triggered to generate a focus following control instruction to control the shooting device to follow focus. Similarly, when the mode switching key is changed from the state B to the state a, the control device may be triggered to generate a mode switching instruction, and the subsequent focus following wheel triggers the control device to generate a zoom control instruction when rotating, so as to control the motor to rotate to drive the zoom ring of the shooting device to rotate.

In another possible mode, the working state of the focusing wheel is controlled to be switched between the focus control and the zoom control according to a mode switching instruction sent by a control terminal.

For example, the handheld cloud deck may further comprise a communication device, and the communication device is used for communicating with the control terminal. When a user needs to convert the working state of the focus following wheel into control focus following by controlling zoom or convert the control focus following into control zoom, the user can send a mode switching instruction to the handheld cloud deck through the control terminal, and the mode switching instruction can include the target working state of the focus following wheel determined by the user. After the handheld cloud platform receives the mode switching instruction, the target working state in the mode switching instruction and the current working state of the focus following wheel are controlled to be electrically connected with the motor or the control device. For example, the target operating state in the mode switching instruction is to control zooming, and the current operating state of the focus following wheel is to control focus following, that is, the focus following wheel is currently electrically connected to the control device, and then the handheld pan/tilt head controls the focus following wheel to be switched to be electrically connected to the motor.

This embodiment is connected with the ring that zooms of shooting equipment through the motor of handheld cloud platform, make this motor drive this ring that zooms at the pivoted in-process and rotate and zoom with this shooting equipment of control, in addition, this handheld cloud platform sends the mode control that follows focus control command to shooting equipment through the control line and follows focus, that is to say, this handheld cloud platform accessible drive-by-wire mode control should shoot equipment and follow focus, and do not need another motor to drive the following focus ring rotation that should shoot equipment and follow focus with this shooting equipment of control, thereby make this handheld cloud platform just can control this shooting equipment under the condition that only needs a motor and zoom and follow focus, the load of this handheld cloud platform has been reduced, be convenient for this handheld cloud platform of user control.

On the basis of the above embodiment, the number of the focus following wheels is at least two, one of the focus following wheels is used for controlling the shooting device to zoom, and the other one of the focus following wheels is used for controlling the shooting device to focus.

As shown in fig. 5, two focus following wheels, for example, focus following wheel 1 and focus following wheel 2, may be connected to the handheld tripod head, wherein focus following wheel 1 is electrically connected to the motor, and focus following wheel 2 is electrically connected to the control device. Correspondingly, the focus following wheel 1 and the focus following wheel 2 can rotate simultaneously or not. When the focus following wheel 1 rotates but the focus following wheel 2 does not rotate, the rotation of the motor can drive the zoom ring to rotate so that the shooting equipment zooms. When the focus following wheel 1 does not rotate and the focus following wheel 2 rotates, the control device can convert the rotation speed of the focus following wheel 2 into a focus following control instruction, and send the focus following control instruction to the shooting device through a control line, so that the shooting device can carry out focus following. It is understood that when the focus following wheel 1 and the focus following wheel 2 are rotated simultaneously, the photographing apparatus can perform zooming and focus following simultaneously.

Alternatively, as shown in fig. 6, the control device in the handheld tripod head can be electrically connected with the two follow-focus wheels through metal contacts. For example, the focus following wheel 1 is used to control the photographing apparatus to zoom, and the focus following wheel 2 is used to control the photographing apparatus to follow focus. Accordingly, when the focus wheel 1 rotates and the focus wheel 2 does not rotate, the control device generates only a zoom control instruction, thereby controlling the photographing apparatus to zoom. When the focus following wheel 1 does not rotate and the focus following wheel 2 rotates, the control device generates only a focus following control command, thereby controlling the photographing apparatus to perform focus following. When the focus following wheel 1 and the focus following wheel 2 rotate simultaneously, the control device can simultaneously generate a zoom control instruction and a focus following control instruction, so as to control the shooting device to zoom and focus following simultaneously.

In addition, in other embodiments, the number of the focus following wheels connected to the handheld tripod head is not limited to two, and may be more than two, for example.

This embodiment is connected with two at least follow focus wheels through this handheld cloud platform for one of them follows focus wheel and is used for control shoot equipment zooms, and one follows focus wheel and is used for control shoot equipment follow focus, can make this shoot equipment zoom simultaneously and follow focus through the rotation of these two follow focus wheels, and need not switch back and forth this follow focus wheel between motor and this controlling means, thereby improved the convenience that this handheld cloud platform of user control.

The embodiment of the invention provides a control method of shooting equipment. Fig. 7 is a flowchart of a control method of a photographing apparatus according to another embodiment of the present invention. As shown in fig. 7, based on the foregoing embodiment, the acquiring the focus following control instruction may include:

and S501, acquiring the rotation speed of the focus following wheel.

In this embodiment, the user may rotate the focus wheel such that the focus wheel rotates. Or, this control terminal can send the control command of controlling this with the burnt wheel rotation to this handheld cloud platform, is controlled this with the burnt wheel rotation by this handheld cloud platform. In the process of rotating the focus following wheel, the focus following wheel can send the rotating speed of the focus following wheel to the control device of the handheld cloud deck in real time or periodically. Accordingly, the control device receives the rotation speed sent by the focusing wheel in real time or periodically.

Step S502, determining the current focus following parameter of the shooting device according to the rotation speed of the focus following wheel, wherein the focus following parameter is used for representing the corresponding relation between the rotation angle of the focus following wheel and the distance of the focus movement of the shooting device, and the rotation speed of the focus following wheel is positively correlated with the current focus following parameter of the shooting device.

In this embodiment, the control device may adjust the current focus following parameter of the photographing apparatus according to the rotation speed of the focus following wheel. That is, the current focus following parameter of the photographing apparatus may be changed as the rotation speed of the focus following wheel is changed.

Specifically, the focus following parameter of the shooting device is used for representing the corresponding relation between the rotation angle of the focus following wheel and the distance of the focus movement of the shooting device. In general, the larger the rotation angle of the focusing wheel, the larger the distance that the focus of the photographing apparatus moves, that is, the larger the rotation angle of the focusing wheel, the more obvious the focusing effect of the photographing apparatus.

In this embodiment, the greater the rotation speed of the focus wheel, the greater the current focus tracking parameter of the photographing apparatus. That is, the faster the tracking wheel rotates, the greater the distance the focus of the photographing apparatus moves when the tracking wheel rotates by the same angle. Similarly, the slower the focus wheel rotates, the smaller the distance the focus of the photographing apparatus moves when the focus wheel rotates by the same angle.

For example, the rotational speed of the tracking wheel is 1rad/s at time t0, and the rotational speed of the tracking wheel is increased to 3rad/s at time t 1. The distance that the focus of the photographing apparatus moves when the tracking wheel rotates by an angle, e.g., theta, at a speed of 3rad/s is greater than the distance that the focus of the photographing apparatus moves when the tracking wheel rotates by the same angle theta at a speed of 1 rad/s. For example, when the tracking wheel rotates at a rotational speed of 1rad/s, the focal point of the photographing apparatus moves by a distance of 1 cm when the tracking wheel rotates by 1 degree. When the focusing wheel rotates at the rotating speed of 3rad/s, the distance of the focus of the shooting device moving when the focusing wheel rotates 1 degree is 3 cm.

Optionally, the focus following parameter of the shooting device includes a focus following gear. The focus following gear is used for representing the distance of the focus of the shooting device when the focus following wheel rotates by a unit angle. For example, the focus tracking position is used to indicate the distance that the focus of the photographing apparatus moves when the focus tracking wheel rotates by 1 degree. The focus tracking position and the distance of the focal point movement of the shooting device are not necessarily in an equal relationship, but may also be in a proportional coefficient relationship, for example, the distance of the focal point movement may be the focus tracking position multiplied by a preset coefficient.

When the rotation speed of the focus following wheel is higher, the focus following gear of the shooting device is higher. That is, the faster the tracking wheel rotates, the greater the distance the focus of the photographing apparatus moves when the tracking wheel rotates 1 degree.

And S503, generating the focus following control instruction according to the current focus following parameters of the shooting equipment.

Furthermore, the control device can convert the rotation speed of the focus following wheel into a focus following control instruction of the shooting device according to the type information of the shooting device and the current focus following parameter of the shooting device, and sends the focus following control instruction to the shooting device through the control line, so that the shooting device can control the lens of the shooting device to follow the focus according to the focus following control instruction, and the drive-by-wire focus following of the shooting device is realized.

Optionally, the generating the focus following control instruction according to the current focus following parameter of the shooting device includes: acquiring the rotation angle of the focus following wheel; and generating a focus following control instruction according to the current focus following parameter of the shooting equipment, the rotation angle of the focus following wheel and the type information of the shooting equipment.

In this embodiment, the focus following wheel can periodically send the rotation speed of the focus following wheel to the control device of the handheld tripod head in the rotation process. For example, the tracking wheel may transmit a rotational speed every 10 milliseconds. The control device can determine the rotation angle of the focus following wheel according to the rotation speed and the transmission period transmitted by the focus following wheel. Assuming that the rotation angle of the focus following wheel is 2 degrees and the current rotation speed of the focus following wheel is 3rad/s, it can be determined that the distance that the focus of the shooting device needs to move is 6 cm according to the current focus following gear of the shooting device and the rotation angle of the focus following wheel.

Or, in other embodiments, an angle sensor may be further disposed on the focus following wheel, the angle sensor being configured to detect a rotation angle of the focus following wheel, and accordingly, the control device obtains the rotation angle of the focus following wheel through the angle sensor.

It is understood that the focus following step values of different types of photographing devices are different, and the focus following step value is understood as the distance that the focus of the photographing device can move every time the control means sends a focus following control command to the photographing device. For example, for the first type of photographing apparatus, the control means may move the focus of the photographing apparatus by a distance of 1 cm for every one follow-up control instruction transmitted to the photographing apparatus. For the second type of photographing apparatus, the control means may move the focus of the photographing apparatus by a distance of 2 cm for every focus following control instruction transmitted to the photographing apparatus. Assuming that the first type of shooting device is mounted on the handheld pan/tilt head, when the distance that the focus of the shooting device needs to move is 6 centimeters, the control device needs to send 6 focus following control instructions to the shooting device. Accordingly, for example, the control device sends 6 focus following control instructions to the shooting device, and the shooting device controls the lens of the shooting device to perform focus following according to the 6 focus following control instructions, so that the focus of the shooting device moves by 6 centimeters.

In this embodiment, the rotation speed of the focus following wheel is obtained, and the current focus following parameter of the shooting device is determined according to the rotation speed of the focus following wheel, so that the rotation speed of the focus following wheel is positively correlated with the current focus following parameter of the shooting device, that is, the faster the focus following wheel rotates, the larger the distance that the focus of the shooting device moves when the focus of the shooting device rotates by the same angle is, and therefore when the focus of the shooting device changes greatly, if it is detected that the speed that the focus following wheel rotates by a user is higher, the distance that the focus of the shooting device moves when the focus of the shooting device rotates by the same angle is increased, and therefore, the purpose of tracking the focus following wheel and the hand is achieved.

The embodiment of the invention provides a control method of shooting equipment. On the basis of the above embodiment, the handheld pan/tilt further includes a communication device, the communication device is used for receiving information sent by the control terminal, and the communication device includes a communication interface or a wireless communication module.

For example, the communication interface may be a wired communication interface, which is not limited to the type of wired communication interface, and may be a serial communication interface, for example. The Wireless communication module may be a Wireless Fidelity (WiFi) communication module, a bluetooth module, or the like. This handheld cloud platform accessible this communication interface carries out wired communication with this control terminal, perhaps, this handheld cloud platform accessible this wireless communication module carries out radio communication with this control terminal. Specifically, the handheld cloud deck can receive the information sent by the control terminal through the communication interface or the wireless communication module.

Optionally, the acquiring the focus following control instruction includes: and receiving the focus following control instruction sent by the control terminal through the communication device.

For example, the control terminal is installed with an APP, the APP is provided with a user interface, and a user can operate on the user interface, for example, the user can click a button or a key on the user interface for controlling the shooting device to follow up. Correspondingly, the control terminal generates a focus following control instruction according to the operation of the user and sends the focus following control instruction to the handheld cradle head. Correspondingly, the handheld cloud platform can receive the focus following control instruction sent by the control terminal through the communication interface or the wireless communication module.

Optionally, the method further includes: receiving a photographing instruction or a video recording instruction sent by the control terminal through the communication device; and sending the photographing instruction or the video recording instruction to the photographing equipment through the control line, wherein the photographing instruction is used for controlling the photographing equipment to photograph, and the video recording instruction is used for controlling the photographing equipment to record video.

In addition, a key or a button for controlling the shooting equipment to shoot or record the video can be displayed on the user interface, when the user operates the key or the button, the control terminal generates a shooting instruction or a video instruction and sends the shooting instruction or the video instruction to the handheld holder. Correspondingly, the handheld cloud deck receives the photographing instruction or the video recording instruction sent by the control terminal through the communication interface or the wireless communication module. Further, the control device in the handheld cloud deck can send the photographing instruction or the video recording instruction to the photographing equipment through a control line, so that the photographing equipment can photograph according to the photographing instruction, or the photographing equipment records video according to the video recording instruction.

Optionally, the method further includes: receiving the setting information sent by the control terminal through the communication device; sending the setting information to the shooting device through the control line, wherein the setting information is used for setting state parameters of the shooting device, and the state parameters of the shooting device include at least one of the following: exposure parameters of the shooting equipment and focus following parameters of the shooting equipment.

In this embodiment, the control terminal may further set a status parameter of the shooting device, for example, the control terminal may set parameters such as an exposure parameter, a focus following parameter, and a zoom parameter of the shooting device.
