The following method embodiments can be executed by a handheld gimbal or a follow focus motor according to one or more embodiments of the present disclosure. The following uses the implementation of a handheld gimbal as an example for description.

FIG. 4 is a flowchart of a shooting control method provided by an embodiment of the disclosure. As shown in FIG. 4, the method of this embodiment can be applied to a shooting control system, which includes a handheld gimbal and a follow focus motor. The handheld gimbal includes a bearing base and a handheld portion for carrying the shooting equipment. Please refer to the examples shown in FIGS. 1 to 3 above. Wherein, the handheld portion includes a first interaction device, and the follow focus motor is meshed with the follow focus ring of the lens of the shooting equipment. The execution subject of the method in this embodiment may be a handheld gimbal, and the method in this embodiment may include the following steps:

S401. Detect that the user performs a first focus confirmation operation on the first interactive device when the shooting target is in focus in the shooting image of the shooting equipment, and the distance between the shooting target and the shooting equipment is the first distance.

In one embodiment, the shooting equipment can obtain a live view image of the shooting target and display the live view image on a display screen (such as a touch display screen). When the distance between the shooting target and the shooting equipment is the first distance and when the user judges that the shooting target is in focus in the shooting image of the shooting equipment by observing the live view screen, that is, the user judges that the shooting target is clearly imaged in the shooting image of the shooting equipment by watching the live view screen, the user performs a focus confirmation operation on the first interactive device, here referred to as the first focus confirmation operation, to confirm that the current shooting target is in focus in the shooting image of the shooting equipment. Correspondingly, the handheld gimbal can detect the first focus confirmation operation of the user on the first interaction device (such as a touch display screen). Wherein, when the user's first focusing confirmation operation on the first interaction device is detected, the distance between the shooting target and the shooting equipment is the first distance.

S402. In response to the first focusing confirmation operation, record the first measured distance between the shooting equipment and the shooting target and the first measured rotation position of the follow focus motor collected by the distance sensor.

In one embodiment, in response to the detected first focusing confirmation operation, the measured distance between the shooting equipment and the shooting target collected by the distance sensor is recorded, here referred to as the first measured distance, and the measured rotation position of the follow focus motor, which is called the first measured rotation position here, is also recorded.

The first measured distance is the distance collected by the distance sensor when the distance between the shooting target and the shooting equipment is the first distance. The first measured rotation position is the rotation position of the follow focus motor measured when the distance between the shooting target and the shooting equipment is the first distance.

S403: Detect that the user performs a second focus confirmation operation on the first interactive device when the shooting target is in focus in the shooting image of the shooting equipment, and the distance between the shooting target and the shooting equipment is the second distance.

In one embodiment, when the distance between the shooting target and the shooting equipment is the second distance and when the user judges that the shooting target is in focus in the shooting image of the shooting equipment by watching the live view, that is, the user judges that the shooting target is clearly imaged in the shooting image of the shooting equipment by watching the live view screen, the user performs a focus confirmation operation on the first interactive device, here referred to as the second focus confirmation operation, to confirm that the current shooting target is in focus in the shooting image of the shooting equipment. Correspondingly, the handheld gimbal can detect the second focus confirmation operation of the user on the first interactive device (such as a touch display screen). Wherein, when the second focusing confirmation operation of the first interaction device by the user is detected, the distance between the shooting target and the shooting equipment is the second distance.

S404. In response to the second focusing confirmation operation, record the second measured distance between the shooting equipment and the shooting target and the second measured rotation position of the follow focus motor collected by the distance sensor.

In one embodiment, in response to the detected second focus confirmation operation, the measured distance between the shooting equipment and the shooting target collected by the distance sensor, here referred to as the second measured distance, is recorded. Furthermore, the measured rotation position of the follow focus motor, here referred to as the second measured rotation position, is also recorded.

The second measured distance is the distance collected by the distance sensor when the distance between the shooting target and the shooting equipment is the second distance. The second measured rotation position is the rotation position of the follow focus motor measured when the distance between the shooting target and the shooting equipment is the second distance.

S405: Acquire a real-time measured distance between the shooting equipment and the shooting target collected by the distance sensor.

In one embodiment, after acquiring the measured distance between the shooting equipment and the shooting target and the measured rotation position of the follow focus motor collected by the distance sensor at different distances between the shooting target and the shooting equipment, the real-time measured distance between the shooting equipment and the shooting target collected by the distance sensor is acquired.

For example, it is detected that the user starts the follow focus shooting confirmation operation of the first interactive device, and in response to the start of the follow focus shooting confirmation operation, the real-time measured distance between the shooting equipment and the shooting target collected by the distance sensor is acquired.

S406. Control the follow focus motor to drive the lens to focus based on the first measured distance, the first measured rotation position, the second measured distance, the second measured rotation position, and the real-time measured distance, so that the shooting target is in focus in the shooting image of the shooting equipment.

In one embodiment, based on the first measured distance, the first measured rotation position, the second measured distance, the second measured rotation position, and the real-time measured distance, the follow focus motor is controlled to drive the lens to focus so that the shooting target is in focus in the shooting image of the shooting equipment. For example, according to the first measured distance, the first measured rotation position, the second measured distance, and the second measured rotation position, the corresponding relationship between the measured distance between the shooting equipment and the shooting target and the rotation position of the follow focus motor when the shooting target is in focus in the shooting image of the shooting equipment can be obtained. Then, according to the corresponding relationship and the real-time measured distance, the rotation position of the follow focus motor when the shooting target is in focus in the shooting image of the shooting equipment under the real-time measured distance can be determined. Then, the position of the follow focus motor is rotated to the determined rotation position. As such, the follow focus motor drives the lens to focus, so that the shooting target is in focus in the shooting image of the shooting equipment.

Optionally, the shooting method can not only controls the follow focus motor to drive the lens to focus, but can also control the shooting equipment to shoot images so as to obtain an image of the shooting target in focus. Optionally, the shooting method may not only controls the follow focus motor to drive the lens to focus, but may also control the shooting equipment to record video so as to obtain a video where the shooting target is always in focus.

The shooting control method of this embodiment can obtain the measured distance between the shooting target and the shooting equipment and the measured rotation position of the follow focus motor collected by the distance sensor by detecting the user's focus confirmation operation on the first interactive device when the shooting target is at different distances from the shooting equipment. Then, the real-time measured distance between the shooting target and the shooting equipment collected by the distance sensor can be obtained. According to the real-time measured distance, and the measured distances and the measured rotation positions of the follow focus motor when the shooting target is at different distances from the shooting equipment collected by the distance sensor, the follow focus motor can be controlled to drive the lens to focus so as to make the shooting target is in focus in the shooting image of the shooting equipment. As such, according to the real-time distance between the shooting target and the shooting equipment, automatic follow focus shooting can be realized, which can simplify the user's operation and/or improve the user's experience.

In some embodiments, the handheld portion of the handheld gimbal can further include a second interactive device, and the user can perform operations on the second interactive device such as focusing adjustment operations. Correspondingly, when the shooting equipment is at a first distance from the shooting target, the user can perform a focus adjustment operation on the second interactive device, herein referred to as a first focus adjustment operation. The first focusing adjustment operation can be used to adjust the shooting target to be in focus in the shooting image. Correspondingly, the handheld gimbal can detect the user's first focus adjustment operation on the second interactive device, and can control the follow focus motor to drive the lens to focus according to the first focus adjustment operation so as to adjust the shooting target to be in focus in the shooting image of the shooting equipment. Then, when the shooting target is in focus in the shooting image of the shooting equipment, the user can perform the above-mentioned first focus confirmation operation on the first interactive device.

Optionally, when the shooting equipment is at a second distance from the shooting target, the user can perform a focus adjustment operation on the second interactive device, which is referred to herein as a second focus adjustment operation. The second focusing adjustment operation can be used to adjust the shooting target to be in focus in the shooting image. Correspondingly, the handheld gimbal can detect the second focus adjustment operation of the user on the second interactive device, and control the follow focus motor to drive the lens to focus according to the second focus adjustment operation so as to adjust the shooting target to be in focus in the shooting image of the shooting equipment. Then, when the shooting target is in focus in the shooting image of the shooting equipment, the user can perform the above-mentioned second focus confirmation operation on the first interactive device.

Therefore, in these embodiments, the user can perform a focus adjustment operation on the second interaction device, so that when the shooting equipment is at different distances from the shooting target, the shooting target can be adjusted to be in focus in the shooting image of the shooting equipment.

In one embodiment, the aforementioned second interaction device can include a focus wheel, such as the focus wheel 103 in FIG. 2. Correspondingly, when the user needs to adjust the shooting target to the in-focus state in the shooting image of the shooting equipment, the user can perform a rotation operation on the focus wheel 103. The rotation of the focus wheel 103 drives the follow focus motor 500 to rotate, and the rotation of the follow focus motor 500 drives the lens to focus.

When the shooting equipment is at a first distance from the shooting target, the user can perform a rotating operation on the focus wheel 103, which is referred to herein as the first rotation operation. Correspondingly, the handheld gimbal 100 detects the user's first rotation operation on the focus wheel 103, and controls the follow focus motor 500 to drive the lens to focus according to the detected first rotation operation so as to adjust the shooting target to an in-focus state in the shooting image of the shooting equipment 200.

Optionally, when the shooting equipment 200 is at a second distance from the shooting target, the user can perform a rotating operation on the focus wheel 103, which is referred to herein as a second rotation operation. Correspondingly, the handheld gimbal 100 detects the user's second rotation operation on the focus wheel 103 and, according to the detected second rotation operation, controls the follow focus motor 500 to drive the lens to focus so as to adjust the shooting target to an in-focus state in the shooting image of the shooting equipment 200.

Therefore, in this embodiment, the user performs rotating operations on the focus wheel 103, so that when the shooting equipment 200 and the shooting target are at different distances, the shooting target can be adjusted to the in-focus state in the shooting image of the shooting equipment 200.

In one embodiment, the first interaction device is a touch display screen. The handheld gimbal 100 in this embodiment can also control the touch display screen to display first distance prompt information. The first distance prompt information is used to instruct the user to focus the shooting equipment to a shooting target about a first reference distance away from the shooting equipment. For example, as shown in FIG. 5A, the first reference distance is 1 meter, and the first distance prompt information can be used to instruct the user to focus the lens of the shooting equipment to a target object at about 1 meter away. Among them, the distance sensor can collect the measured distance between the shooting equipment and the shooting target. Optionally, the handheld gimbal can also control the touch display screen to display the measured distance collected by the distance sensor, such as 2 meters in FIG. 5A. The handheld gimbal can determine the deviation between the first reference distance and the measured distance collected by the distance sensor, and determine whether the deviation is greater than a preset deviation threshold. If the deviation between the first reference distance and the measured distance collected by the distance sensor is greater than the preset deviation threshold, the touch display screen can be controlled to display first distance adjustment information prompting the user to adjust the distance between the shooting equipment and the shooting target according to the deviation. For example, as shown in FIG. 5A, the first distance adjustment information may prompt the user to move the focus object (shooting target) closer, and the user may move the shooting equipment closer to the shooting target according to the first distance adjustment information. If the deviation between the first reference distance and the measured distance collected by the distance sensor is less than or equal to the preset deviation threshold, can mean that the shooting equipment is at about a first reference distance away from the shooting target. At this time, the shooting equipment is at the first distance away from the shooting target.

In one embodiment, the first interaction device is a touch display screen. The handheld gimbal in this embodiment can also control the touch display screen to display second distance prompt information, which can be used to instruct the user to focus the shooting equipment to a shooting target at about a second reference distance away from the shooting equipment. For example, the second reference distance is 5 meters. As shown in FIG. 6A and FIG. 6B, the second distance prompt information can be used to instruct the user to focus the lens of the shooting equipment to a target object at about 5 meters away. Among them, the distance sensor can collect the measured distance between the shooting equipment and the shooting target. Optionally, the handheld gimbal can also control the touch display screen to display the measured distance collected by the distance sensor. The handheld gimbal can determine the deviation between the second reference distance and the measured distance collected by the distance sensor, and determine whether the deviation is greater than a preset deviation threshold. If the deviation between the second reference distance and the measured distance collected by the distance sensor is greater than the preset deviation threshold, the touch screen can be controlled to display the second distance adjustment information prompting the user to adjust the distance between the shooting equipment and the shooting target according to the deviation. If the deviation between the second reference distance and the measured distance collected by the distance sensor is less than or equal to the preset deviation threshold, this can mean that the shooting equipment is at about a second reference distance from the shooting target. At this time, the shooting equipment is at the second distance from the shooting target.

Therefore, this embodiment can display the distance prompt information for instructing the user to focus the lens of the shooting equipment to the shooting target at about different reference distances through the touch display screen, and detect the measured distance between the shooting equipment and the shooting target through the distance sensor. According to the measured distance and the reference distance, the touch display screen displays the distance adjustment information prompting the user to adjust the distance between the shooting equipment and the shooting target, so that the user can adjust the distance between the shooting equipment and the shooting target according to the distance adjustment information to ensure the distance between the shooting equipment and the shooting target is close to the above-mentioned reference distance. This can allow the user to perform a focus confirmation operation when the distance is close to the reference distance.

In one embodiment, the first interaction device is a touch display screen. A possible implementation of the above S401 is: controlling the touch display screen to display the first focus confirmation icon, and then detecting that the user performs the first focus confirmation operation on the first focus confirmation icon when the shooting target is in the focus state in the shooting image of the shooting equipment.

As shown in FIG. 5D, the first focus confirmation icon is the “confirm focused” icon displayed in FIG. 5D. If the user observes the shooting screen of the shooting equipment and determines that the shooting target is in focus in the shooting image of the shooting equipment, the user can perform the first focus confirmation operation on the first focus confirmation icon. That is, the user can perform a click operation on the “confirm focused” icon shown in FIG. 5D. Correspondingly, the handheld gimbal detects the user's click operation on the “confirm focused” icon displayed on the touch screen.

A possible implementation of the above S403 is: controlling the touch display screen to display the second focus confirmation icon, and then detecting that the user performs a second focus confirmation operation on the second focus confirmation icon when the shooting target is in a focus state in the shooting image of the shooting equipment.

As shown in FIG. 6B, the second focus confirmation icon is the “confirm focused” icon displayed in FIG. 6B. If the user observes the shooting screen of the shooting equipment and determines that the shooting target is in focus in the shooting image of the shooting equipment, the user can perform the second focus confirmation operation on the second focus confirmation icon. That is, the user can perform a click operation on the “confirm focused” icon shown in FIG. 6B. Correspondingly, the handheld gimbal can detect that the user clicks on the “confirm focused” icon displayed on the touch screen.

Optionally, when the distance between the shooting equipment and the shooting target is the first distance, it also can be determined whether the time period during which the shooting equipment remains stable is less than a preset time period. If the time period during which the shooting equipment remains stable is greater than or equal to the preset time period, the first focus confirmation icon can be adjusted from the non-responsive state to the responsive state. If the time period that the shooting equipment remains stable is less than the preset time period, the touch screen can be controlled to display a prompt message for instructing the user to keep the shooting equipment stable, and at the same time, the first focus confirmation icon is set to a non-responsive state.

In one embodiment, as shown in FIG. 5B, if the deviation between the first reference distance and the measured distance between the shooting equipment and the shooting target changes from greater than the preset distance deviation threshold to less than or equal to the preset distance deviation threshold, it can indicate that the distance between the shooting equipment and the shooting target is close to the first reference distance. At this time, the distance between the shooting equipment and the shooting target is the first distance. At the same time, the touch screen can be controlled to display a prompt message for instructing to keep the shooting equipment stable, and shows that the first focus confirmation icon is at a non-responsive state. As shown in FIG. 5B, the “confirm focused” icon is a grayscale icon. The user can keep the shooting equipment stable according to the prompt information. When the handheld gimbal detects that the shooting equipment is stable, it starts to count the time period the shooting equipment remains stable, and judges whether the time period the shooting equipment remains stable is less than the preset time period. If the shooting equipment remains stable for less than the preset time period, the touch display screen can be controlled to continue to display the first focus confirmation icon as non-responsive. Optionally, the touch display screen can be controlled to display the length of time the shooting equipment remains stable. For example, a progress bar in the preset time period can be displayed for the length of time the shooting equipment remains stable, as shown in FIG. 5C. If the shooting equipment remains stable for a time period greater than or equal to the preset time period, the first focus confirmation icon displayed on the touch screen can be adjusted from a non-responsive state to a responsive state. As shown in FIG. 5D, the “confirm focused” icon is a lit icon.

Optionally, when the distance between the shooting equipment and the shooting target is the second distance, it also can be determined whether the time period during which the shooting equipment remains stable is less than a preset time period. If the time period during which the shooting equipment remains stable is greater than or equal to the preset time period, the second focus confirmation icon can be adjusted from the non-responsive state to the responsive state, as shown in FIG. 6B. If the time period the shooting equipment remains stable is less than the preset time period, the touch screen can be controlled to display a prompt message for instructing to keep the shooting equipment stable, and the second focus confirmation icon is set to a non-responsive state, as shown in FIG. 6A.

FIG. 7 is a flowchart of a shooting control method provided by an embodiment of the present disclosure. As shown in FIG. 7, the method of this embodiment can be applied to a shooting control system, which includes a handheld gimbal and a follow focus motor. The handheld gimbal includes a bearing base and a handheld portion for carrying the shooting equipment. Please refer to the examples shown in FIGS. 1 to 3 above. Among them, the handheld portion includes a touch display screen, and the follow focus motor is meshed with the follow focus ring of the lens of the shooting equipment. The execution subject of the method in this embodiment may be a handheld gimbal, and the method in this embodiment may include:

S701. Control the touch display screen to display a first focus setting interface of the lens, and detect a first setting operation of the user on the first focus setting interface.

S702. Determine a first target focus parameter of the lens according to the detected first setting operation, where the first target focus parameter represents a first rotation angle of the follow focus ring.

In this embodiment, the first focus setting interface of the lens is displayed on the touch screen controlled by the handheld gimbal. The first focus setting interface can be used to set the focus parameters of one point. Then, the user can perform a focus parameter setting operation on the first focus setting interface, which is referred to herein as a first setting operation. Correspondingly, the handheld gimbal can detect the user's first setting operation on the first focus setting interface, and then determine the target focus parameter of the lens of the shooting equipment according to the detected first setting operation, which is referred to herein as the first target focus parameter. The target focus parameter can be used to characterize the first rotation angle of the follow focus ring.

FIG. 8A shows an exemplary interface for setting the focus parameters of two points, point A and point B respectively, which represents the change of the focus parameter of point A to the focus parameter of point B. When the user clicks the setting icon of point A or the “Next Step” icon shown in FIG. 8A, the touch display screen displays the interface as shown in FIG. 8B. FIG. 8B shows the focus setting interface of point A, which is the first focus setting interface described above. The user can set the interface shown in FIG. 8B, such as sliding up and down or left and right on the focal length value icon corresponding to point A to set the focal length required by the user. The size of this focal length can represent the rotation angle of the follow focus ring. For example, when the user observes that the shooting target is in focus in the shooting image of the shooting equipment, the user stops sliding. Correspondingly, the handheld gimbal can determine the first target focal length of the lens according to the user's setting operation on the interface shown in FIG. 8B, for example, 30.

S703. Control the touch display screen to display a second focus setting interface of the lens, and detect a second setting operation of the user on the second focus setting interface.

S704. Determine a second target focus parameter of the lens according to the detected second setting operation, where the second target focus parameter represents a second rotation angle of the follow focus ring.

In this embodiment, the second focus setting interface of the lens is displayed on the touch display screen controlled by the handheld gimbal. The second focus setting interface can be used to set the focus parameter of another point, and then the user performs the focus parameter setting operation on the second focus setting interface, which is herein referred to as the second setting operation. Correspondingly, the handheld gimbal can detect the user's second setting operation on the second focus setting interface, and then determine the target focus parameter of the lens of the shooting equipment according to the detected second setting operation, which is referred to herein as the second target focus parameter. The second target focus parameter can be used to characterize the second rotation angle of the follow focus ring.

As shown in FIG. 8B, after the user completes the setting operation of point A, when the user clicks the setting icon of point B or the “Next Step” icon shown in FIG. 8B, the handheld gimbal can control the touch screen to display the interface shown in FIG. 8C. FIG. 8C shows the focus setting interface of point B, which is the second focus setting interface described above. The user can perform a setting operation on the interface shown in FIG. 8C, such as sliding up and down or left and right on the focal length value icon corresponding to point B to set the focal length required by the user. The size of this focal length can represent the rotation angle of the follow focus ring. For example, when the user observes that the shooting target is in focus in the shooting image of the shooting equipment, the user stops sliding. Correspondingly, the handheld gimbal can determine the second target focal length of the lens according to the user's setting operation on the interface shown in FIG. 8C, for example, 50.

S705: Control the follow focus motor to drive the lens to focus according to the first target focus parameter and the second target focus parameter, and control the shooting equipment to shoot the video.

In this embodiment, since the first target focus parameter represents the first rotation angle of the follow focus ring, and the second target focus parameter represents the second rotation angle of the follow focus ring, the first rotation angle of the follow focus ring is determined according to the first target focus parameter, and the second rotation angle of the follow focus ring is determined according to the second target focus parameter. Then, according to the follow focus ring from the first rotation angle to the second rotation angle, the follow focus motor can be controlled to rotate. In the process that the follow focus motor rotates and drives the follow focus ring to rotate, the lens is driven to focus. At the same time, the shooting equipment can be controlled to shoot the video, and the shooting target in the obtained video can be in focus.

In these embodiments, different focus setting interfaces are displayed through the touch display screen of the handheld gimbal, and different target focus parameters can be determined according to the user's setting operations on each of the focus setting interfaces. Then, according to each target focus parameter, such as in the process of changing from one target focus parameter to another target focus parameter, the follow focus motor can be controlled to drive the lens to focus, and the shooting equipment can be controlled to shoot video, so that the shooting target is in focus on the shooting screen of the shooting equipment. Thus, according to the focus parameters set by the user, automatic follow-focus shooting can be realized, the user's operation can be simplified, and/or the user's experience can be improved.

Based on the embodiment shown in FIG. 7, the method of this embodiment may further include: detecting a video duration setting operation of the user on the touch screen, and determining the target video duration according to the detected video duration setting operation. Correspondingly, a possible implementation of S705 is: controlling the follow focus motor to drive the lens to focus and controlling the shooting equipment to shoot the video according to the first target focus parameter, the second target focus parameter, and the target video duration. In this embodiment, the duration from the first target focus parameter to the second target focus parameter is the aforementioned target video duration. The obtained video can be a video whose duration is the target video duration during which the first target focus parameter changes to the second target focus parameter.

In one embodiment, the handheld gimbal can control the touch display screen to display the video duration setting interface. For example, as shown in FIG. 8C, when the user clicks on the “Next Step” icon in the interface shown in FIG. 8C, the handheld gimbal can control the touch screen to display the video duration setting interface. For example, FIG. 8D shows the video duration setting interface. The user can perform a setting operation on the interface shown in FIG. 8D, for example, slide up and down on the minute value icon and the second value icon on the interface to set the duration. For example, when the user stops sliding, correspondingly, the handheld gimbal can determine the video duration according to the user's setting operation on the interface shown in FIG. 8D, for example, 1 minute and 2 seconds. When the user clicks on the “Start Shooting” icon in the interface shown in FIG. 8D, the handheld gimbal will control the follow focus motor according to the focal length 30 and the focal length 50 to drive the lens to focus, and control the shooting equipment to take 1 minute 2 seconds of video. Therefore, through the above method, it is possible to realize automatic follow-focus shooting within the video duration set by the user.

FIG. 9 is a flowchart of a shooting control method according to an embodiment of the present disclosure. As shown in FIG. 9, the method of this embodiment can be applied to a shooting control system, which includes a handheld gimbal and a follow focus motor. The handheld gimbal includes a bearing base and a handheld portion for carrying the shooting equipment. Please refer to the examples shown in FIGS. 1-3. Wherein, the handheld portion includes a first interaction device, and the follow focus motor is meshed with the zoom ring of the lens of the shooting equipment. The execution subject of the method in this embodiment may be a handheld gimbal, and the method in this embodiment may include:

S901. Detect that when the size of the shooting target in the shooting image of the shooting equipment is the target size, the user performs a first zoom confirmation operation on the first interactive device, and the distance between the shooting target and the shooting equipment is the first distance.

In this embodiment, the shooting equipment can obtain a live view image of the shooting target, and display the live view image on a display screen (such as a touch screen). When the distance between the shooting target and the shooting equipment is the first distance and when the user judges that the size of the shooting target in the shooting image of the shooting equipment is the target size by watching the live view screen, the user performs a zoom confirmation operation on the first interactive device, which is herein referred to as the first zoom confirmation operation, to confirm that the size of the current shooting target in the shooting image of the shooting equipment is the target size. Correspondingly, the handheld gimbal can detect the user's first zoom confirmation operation on the first interactive device (such as a touch screen). Wherein, when the user's first zoom confirmation operation on the first interaction device is detected, the distance between the shooting target and the shooting equipment is the first distance.

Optionally, the target size is set by the user. For example, the user can judge whether the size of the shooting target in the shooting image of the shooting equipment is the target size by observing the number of grids occupied by the shooting target in the live view screen displayed on the display screen.

S902. In response to the first zoom confirmation operation, record the first measured distance between the shooting equipment and the shooting target and the first measured rotation position of the follow focus motor collected by the distance sensor.

In this embodiment, in response to the detected first zoom confirmation operation, the measured distance between the shooting equipment and the shooting target collected by the distance sensor is recorded, which is herein referred to as the first measured distance. The measured rotation position of the follow focus motor is also recorded, which is herein referred to as the first measured rotation position.

S903. Detect that the user performs a second zoom confirmation operation on the first interaction device when the size of the shooting target in the shooting image of the shooting equipment is the target size, and the distance between the shooting target and the shooting equipment is the second distance.

In this embodiment, when the distance between the shooting target and the shooting equipment is the second distance, and when the user judges that the size of the shooting target in the shooting image of the shooting equipment is the target size by observing the live view screen, the user can perform a zoom confirmation operation on the first interactive device, which is herein referred to as a second zoom confirmation operation, to confirm that the size of the current shooting target in the shooting image of the shooting equipment is the target size. Correspondingly, the handheld gimbal can detect the second zoom confirmation operation of the user on the first interactive device (such as a touch screen). Wherein, when the second zoom confirmation operation of the first interactive device by the user is detected, the distance between the shooting target and the shooting equipment is the second distance.

S904. In response to the second zoom confirmation operation, record the second measured distance between the shooting equipment and the shooting target and the second measured rotation position of the follow focus motor collected by the distance sensor.

In this embodiment, in response to the detected second zoom confirmation operation, the measured distance between the shooting equipment and the shooting target collected by the distance sensor is recorded, here referred to as the second measured distance, and the follow focus motor is also recorded. The measured rotational position is referred to here as the second measured rotational position.

S905: Acquire a real-time measured distance between the shooting equipment and the shooting target collected by the distance sensor.

In this embodiment, after acquiring the measured distance between the shooting equipment and the shooting target collected by the distance sensor and the measured rotation position of the follow focus motor when the shooting target is at different distances from the shooting equipment, the real-time measured distance between the shooting equipment and the shooting target collected by the distance sensor is obtained.

For example, it is detected that the user starts the zoom shooting confirmation operation, and in response to the start of the zoom shooting confirmation operation, the real-time measured distance between the shooting equipment and the shooting target collected by the distance sensor can be acquired.

S906. Control the follow focus motor to drive the lens zoom according to the first measured distance, the first measured rotation position, the second measured distance, the second measured rotation position, and the real-time measured distance, so that the size of the shooting target in the shooting image of the shooting equipment is the target size.

In this embodiment, the follow focus motor can be controlled to drive the lens to zoom according to the first measured distance, the first measured rotation position, the second measured distance, the second measured rotation position, and the real-time distance, so that the size of the shooting target in the shooting image of the shooting equipment is the target size. For example, according to the first measured distance, the first measured rotation position, the second measured distance, and the second measured rotation position, the corresponding relationship between the measured distance between the shooting equipment and the shooting target and the rotation position of the follow focus motor when the size of the shooting target in the shooting image of the shooting equipment is the target size can be obtained. Then, according to the corresponding relationship and the real-time measured distance, the rotation position of the follow focus motor can be determined when the size of the shooting target in the shooting image of the shooting equipment is the target size under the real-time measured distance. Then the position of the follow focus motor is rotated to the determined rotation position. As such, the follow focus motor drives the lens to zoom so that the size of the shooting target in the shooting image of the shooting equipment is the target size.

Optionally, this shooting method not only controls the follow focus motor to drive the lens zoom, but also controls the shooting equipment to shoot images to obtain an image with the shooting target as the shooting size. Optionally, the method not only controls the follow focus motor to drive the lens zoom, but also controls the shooting equipment to record video to obtain a video whose size of the shooting target remains the target size.

The shooting control method of this embodiment can obtain the measured distance between the shooting target and the shooting equipment and the measured rotation position of the follow focus motor collected by the distance sensor by detecting the user's zoom confirmation operations on the first interactive device when the shooting target is at different distances from the shooting equipment. Then, the real-time measured distance between the shooting target and the shooting equipment collected by the distance sensor can be obtained. According to the real-time measured distance and the measured distances collected by the distance sensor and the measured rotation positions of the follow focus motor when the shooting target is at different distances from the shooting equipment, the follow focus motor can be controlled to drive the lens zoom so that the size of the shooting target in the shooting image of the shooting equipment is the target size. Thus, according to the real-time distance between the shooting equipment and the shooting target, sliding zoom shooting can be realized, which can simplify the user's operation and/or improve the user's experience.

In some embodiments, the handheld portion of the handheld gimbal can further include a second interactive device, and the user can perform operations on the second interactive device, such as zoom adjustment operations. Correspondingly, when the shooting equipment is at a first distance from the shooting target, the user can perform a zoom adjustment operation on the second interactive device, which is herein referred to as a first zoom adjustment operation. The first zoom adjustment operation can be used to adjust the size of the shooting target in the shooting image to the target size. Correspondingly, the handheld gimbal can detect the user's first zoom adjustment operation on the second interactive device, and control the follow focus motor to drive the lens to zoom according to the first zoom adjustment operation, so as to adjust the size of the shooting target to the target size in the shooting image of the shooting equipment. Then, when the size of the shooting target in the shooting image of the shooting equipment is the target size, the user can perform the above-mentioned first zoom confirmation on the first interactive device.

Optionally, when the shooting equipment is at a second distance from the shooting target, the user can perform a zoom adjustment operation on the second interactive device, which is herein referred to as a second zoom adjustment operation. The second zoom adjustment operation can be used to adjust the size of the shooting target in the shooting image to the target size. Correspondingly, the handheld gimbal can detect the second zoom adjustment operation of the second interactive device by the user, and control the follow focus motor to drive the lens to zoom according to the second zoom adjustment operation, so as to adjust the size of the shooting target to the target size in the shooting image of the shooting equipment. Then, when the size of the shooting target in the shooting image of the shooting equipment is the target size, the user can perform the second zoom confirmation operation on the first interactive device.

Therefore, in these embodiments, the user can perform zoom adjustment operations on the second interaction device, so that when the shooting equipment is at different distances from the shooting target, the size of the shooting target in the shooting image of the shooting equipment can be adjusted to the target size.

In a possible implementation manner, the aforementioned second interaction device includes a zoom wheel, such as the zoom wheel 103 in FIG. 2. Correspondingly, when the user needs to adjust the size of the shooting target to the target size in the shooting image of the shooting equipment, the user can perform a rotation operation on the zoom wheel. The rotation of the zoom wheel will drive the follow focus motor to rotate, and the follow focus motor rotation drives the zoom ring to rotate, and the rotation of the zoom ring drives the lens to zoom.

When the shooting equipment is at a first distance from the shooting target, the user can perform a rotating operation on the zoom wheel, which is herein referred to as the first rotation operation. The first rotation operation can control the follow focus motor to drive the lens to zoom to adjust the size of the shooting target to the target size in the shooting image of the shooting equipment.

Optionally, when the shooting equipment is at a second distance from the shooting target, the user can perform a rotating operation on the zoom wheel, which is herein referred to as the second rotation operation. The second rotation operation can control the follow focus motor to drive the lens to zoom to adjust the size of the shooting target to the target size in the shooting image of the shooting equipment.

Therefore, in these embodiments, the user can perform rotating operations on the zoom wheel, so that when the shooting equipment is at different distances from the shooting target, the size of the shooting target in the shooting image of the shooting equipment can be adjusted to the target size.

In one embodiment, the first interaction device is a touch display screen. The handheld gimbal in this embodiment can also control the touch display screen to display first distance prompt information. The first distance prompt information can be used to instruct the user to control the zoom of the shooting equipment so that the size of the shooting target in the shooting frame of the shooting equipment is the target size when the shooting equipment is about a first reference distance away from the shooting target. For example, as shown in FIG. 10A, the first reference distance is 1 meter, and the first distance prompt information can be used to instruct the user to control the lens to zoom on the target object at about 1 meter away. Among them, the distance sensor can collect the measured distance between the shooting equipment and the shooting target. Optionally, the handheld gimbal can also control the touch display screen to display the measured distance collected by the distance sensor, such as 2 meters as shown in FIG. 10A. The handheld gimbal can determine the deviation between the first reference distance and the measured distance collected by the distance sensor, and determine whether the deviation is greater than a preset deviation threshold. If the deviation between the first reference distance and the measured distance collected by the distance sensor is greater than the preset deviation threshold, the touch display screen can be controlled to display first distance adjustment information prompting the user to adjust the distance between the shooting equipment and the shooting target according to the deviation. For example, as shown in FIG. 10A, the first distance adjustment information may prompt the user to move the zoom object (shooting target) closer, and the user may move the shooting equipment closer to the shooting target according to the first distance adjustment information. If the deviation between the first reference distance and the measured distance collected by the distance sensor is less than or equal to the preset deviation threshold, it can mean that the shooting equipment is about a first reference distance from the shooting target. At this time, the shooting equipment is at the first distance from the shooting target.

In one embodiment, the first interaction device is a touch display screen. The handheld gimbal in this embodiment can also control the touch display screen to display second distance prompt information. The second distance prompt information can be used to instruct the user to control the zoom of the shooting equipment so that when the shooting equipment is about a second reference distance away from the shooting target, the size of the shooting target in the shooting image of the shooting equipment is the target size. For example, the second reference distance is 5 meters. As shown in FIG. 11A and FIG. 11B, the second distance prompt information can be used to instruct the user to control the lens to zoom on the target object at about 5 meters. Among them, the distance sensor can collect the measured distance between the shooting equipment and the shooting target. Optionally, the handheld gimbal can also control the touch display screen to display the measured distance collected by the distance sensor. The handheld gimbal can determine the deviation between the second reference distance and the measured distance collected by the distance sensor, and determine whether the deviation is greater than a preset deviation threshold. If the deviation between the second reference distance and the measured distance collected by the distance sensor is greater than the preset deviation threshold, the touch screen can be controlled to display the second distance adjustment information prompting the user to adjust the distance between the shooting equipment and the shooting target according to the deviation. If the deviation between the second reference distance and the measured distance collected by the distance sensor is less than or equal to the preset deviation threshold, it can mean that the shooting equipment is at about a second reference distance from the shooting target. At this time, the shooting equipment is at the second distance from the shooting target.

Therefore, in those embodiments, the touch display screen can be used to display distance prompt information for instructing the user to control zooming of the lens of the shooting equipment, so that the size of the shooting target in the shooting screen is the target size when the shooting equipment is at different reference distances from the target object. The distance sensor detects the measured distance between the shooting equipment and the shooting target. According to the measured distances and the reference distances, the touch display screen displays the distance adjustment information prompting the user to adjust the distance between the shooting equipment and the shooting target, so that the user can adjust the distance between the shooting equipment and the shooting target according to the distance adjustment information. This can ensure that the distance between the shooting equipment and the shooting target is close to the above-mentioned reference distance, so that the user can perform the zoom confirmation operation when the distance is close to the reference distance.

In one embodiment, the first interaction device is a touch display screen. A possible implementation of the above S901 is: controlling the touch display screen to display the first zoom confirmation icon, and then detecting that the user confirms the operation of the first zoom confirmation on the first zoom confirmation icon when the size of the shooting target in the shooting image of the shooting equipment is the target size.

As shown in FIG. 10D, the first zoom confirmation icon is the “confirm zoomed” icon displayed in FIG. 10D. If the user observes the shooting image of the shooting equipment and determines that the size of the shooting target in the shooting image of the shooting equipment is the target size, the user can perform the first zoom confirmation operation on the first zoom confirmation icon. That is, the user can perform a click operation on the “confirm zoomed” icon shown in FIG. 10D. Accordingly, the handheld gimbal can detect the user's click operation on the “confirm zoomed” icon displayed on the touch display screen.

A possible implementation of the above S903 is: controlling the touch display screen to display the second zoom confirmation icon, and then detecting that the user confirms the second zoom operation on the second zoom confirmation icon when the size of the shooting target in the shooting image of the shooting equipment is the target size.

As shown in FIG. 10D, the second zoom confirmation icon is the “confirm zoomed” icon displayed in FIG. 10D. If the user observes the shooting image of the shooting equipment and determines that the size of the shooting target in the shooting image of the shooting equipment is the target size, the user can perform the second zoom confirmation operation on the second zoom confirmation icon. That is, the user can perform a click operation on the “confirm zoomed” icon shown in FIG. 10D. Correspondingly, the handheld gimbal can detect the user's click operation on the “confirm zoomed” icon displayed on the touch screen.

Optionally, when the distance between the shooting equipment and the shooting target is the first distance, it also can be determined whether the time period during which the shooting equipment remains stable is less than a preset time period. If the time period during which the shooting equipment remains stable is greater than or equal to the preset time period, the first zoom confirmation icon can be adjusted from the non-responsive state to the responsive state. If the time period that the shooting equipment remains stable is less than the preset time period, the touch screen can be controlled to display a prompt message for instructing to keep the shooting equipment stable, and the first zoom confirmation icon can be set to a non-responsive state.

As shown in FIG. 10B, if the deviation between the first reference distance and the measured distance between the shooting equipment and the shooting target changes from greater than the preset distance deviation threshold to less than or equal to the preset distance deviation, it can mean that the distance between the shooting equipment and the shooting target is close to the first reference distance. At this time, the distance between the shooting equipment and the shooting target is the first distance. At the same time, the touch display screen can be controlled to display a prompt message for instructing to keep the shooting equipment stable, and the first zoom confirmation icon is displayed as a non-responsive state. As shown in FIG. 10B, the “confirm zoomed” icon is a grayscale icon. The user can keep the shooting equipment stable according to the prompt information. When the handheld gimbal detects that the shooting equipment is stable, it can start to count the length of time the shooting equipment remains stable, and judge whether the time period the shooting equipment remains stable is less than the preset time period. If the shooting equipment remains stable for less than the preset time period, the touch display screen can be controlled to continue to display the first zoom confirmation icon as non-responsive. Optionally, it also can be possible to control the touch display screen to display the length of time that the shooting equipment remains stable. For example, it can display a progress bar for the time period the shooting equipment remains stable in the preset time period, as shown in FIG. 10C. If the shooting equipment remains stable for a time period greater than or equal to the preset time period, the first zoom confirmation icon displayed on the touch screen can be adjusted from the non-responsive state to the responsive state. As shown in FIG. 10D, the “confirm zoomed” icon is a lit icon.

Optionally, when the distance between the shooting equipment and the shooting target is the second distance, it also can be determined whether the time period during which the shooting equipment remains stable is less than a preset time period. If the time period during which the shooting equipment remains stable is greater than or equal to the preset time period, the second zoom confirmation icon can be adjusted from the non-responsive state to the responsive state, as shown in FIG. 11B. If the time period that the shooting equipment remains stable is less than the preset time period, the touch screen can be controlled to display a prompt message for instructing to keep the shooting equipment stable. The second zoom confirmation icon is set to a non-responsive state, as shown in FIG. 11A.

FIG. 12 is a flowchart of a shooting control method provided by an embodiment of the present disclosure. As shown in FIG. 12, the method of this embodiment can be applied to a shooting control system, which includes a handheld gimbal and a follow focus motor. The handheld gimbal includes a bearing base and a hand-held portion for carrying the shooting equipment. Please refer to the examples shown in FIGS. 1-3. Among them, the handheld portion includes a touch display screen, and the follow focus motor is meshed with the zoom ring of the lens of the shooting equipment. The execution subject of the method in this embodiment may be a handheld gimbal, and the method in this embodiment may include:

S1201. Control the touch screen to display the first zoom setting interface of the lens, and detect the first setting operation of the user on the first zoom setting interface.

S1202. Determine a first target zoom parameter of the lens according to the detected first setting operation, where the first target zoom parameter represents a first rotation angle of the zoom ring.

In this embodiment, the first zoom setting interface of the lens is displayed on the touch screen controlled by the handheld gimbal. The first zoom setting interface can be used to set the zoom parameter of one point, and then the user can perform the zoom parameter setting operation on the first zoom setting interface, which is herein referred to as the first setting operation. Correspondingly, the handheld gimbal can detect the user's first setting operation on the first zoom setting interface, and then determine the target zoom parameter of the lens of the shooting equipment according to the detected first setting operation, which is herein referred to as the first target zoom parameter. The target zoom parameter can be used to characterize the first rotation angle of the zoom ring.

FIG. 13A shows the interface for setting the zoom parameters of two points, point A and point B respectively, which represents the change from the zoom parameter of point A to the zoom parameter of point B. When the user clicks the setting icon of point A or the “Next Step” icon shown in FIG. 13A, the handheld gimbal can control the touch display screen to display the interface shown in FIG. 13B. FIG. 13B shows the zoom setting interface of point A, which is the first zoom setting interface mentioned above. The user can perform a setting operation on the interface shown in FIG. 13B, such as sliding up and down or left and right on the focal length value icon corresponding to point A to set the focal length required by the user. The size of this focal length can represent the rotation angle of the zoom ring. For example, when the user observes that the size of the shooting target in the shooting image of the shooting equipment is the target size, the user can stop sliding. Correspondingly, the handheld gimbal can determine the first target focal length of the lens according to the user's setting operation on the interface shown in FIG. 13B, for example, 30.

S1203. Control the touch display screen to display the second zoom setting interface of the lens, and detect the second setting operation of the user on the second zoom setting interface.

S1204. Determine a second target zoom parameter of the lens according to the detected second setting operation, where the second target zoom parameter represents a second rotation angle of the zoom ring.

In this embodiment, the second zoom setting interface of the lens is displayed on the touch display screen controlled by the handheld gimbal. The second zoom setting interface can be used to set the zoom parameter of another point, and then the user can perform the zoom parameter setting operation on the second zoom setting interface, which is herein referred to as the second setting operation. Correspondingly, the handheld gimbal can detect the second setting operation of the user on the second zoom setting interface, and then can determine the target zoom parameter of the lens of the shooting equipment according to the detected second setting operation, which is herein referred to as the second target zoom parameter. This second target zoom parameter can be used to characterize the second rotation angle of the zoom ring.

As shown in FIG. 13B, after the user completes the setting operation for point A, when the user clicks the setting icon of point B or the “Next Step” icon shown in FIG. 13B, the handheld gimbal can control the touch display screen to display the interface shown in FIG. 13C. FIG. 13C shows the zoom setting interface at point B, which is the second zoom setting interface described above. The user can perform a setting operation on the interface shown in FIG. 13C, such as sliding up and down or left and right on the focal length value icon corresponding to point B to set the focal length required by the user. The size of this focal length can represent the rotation angle of the zoom ring. For example, when the user observes that the size of the shooting target in the shooting image of the shooting equipment is the target size, the user can stop sliding. Correspondingly, the handheld gimbal can determine the second target focal length of the lens according to the user's setting operation on the interface shown in FIG. 13C, for example, 50.

S1205: Control the follow focus motor to drive the lens to zoom according to the first target zoom parameter and the second target zoom parameter, and control the shooting equipment to shoot the video.

In this embodiment, since the first target zoom parameter represents the first rotation angle of the zoom ring, and the second target zoom parameter represents the second rotation angle of the zoom ring, the first rotation angle of the zoom ring can be determined according to the first target zoom parameter, and the second rotation angle of the zoom ring can be determined according to the second target zoom parameter. Then, according to the zoom ring from the first rotation angle to the second rotation angle, the rotation of the follow focus motor can be controlled to drive the lens to zoom in the process of rotating the follow focus motor to drive the zoom ring to rotate. At the same time, the shooting equipment can be controlled to shoot the video, and the size of the shooting target in the obtained video is the target size.

In those embodiments, different zoom setting interfaces can be displayed through the touch display screen of the handheld gimbal, and different target zoom parameters can be determined according to the user's setting operations on zoom setting interfaces. Then, according to each target zoom parameter, such as changing from one target zoom parameter to another target zoom parameter, the follow focus motor can be controlled to drive the lens to zoom, and the shooting equipment can be controlled to shoot video, so that the size of the shooting target on the shooting screen of the shooting equipment is the target size. Thus, according to the zoom parameters set by the user, the sliding zoom shooting function can be realized, the user's operation can be simplified, and/or the user's experience can be improved.

Based on the embodiment shown in FIG. 12, the method of this embodiment may further include: detecting a video duration setting operation of the user on the touch display screen, and determining the target video duration according to the detected video duration setting operation. Correspondingly, a possible implementation of S1205 is: controlling the follow focus motor to drive the lens to zoom according to the first target zoom parameter, the second target zoom parameter, and the target video duration, and controlling the shooting equipment to shoot the video. In this embodiment, the duration from the first target zoom parameter to the second target zoom parameter is the aforementioned target video duration, and the obtained video can be a video whose duration is the target video duration during which the first target zoom parameter is changed to the second target zoom parameter.

In this embodiment, the handheld gimbal can control the touch display screen to display the video duration setting interface. For example, as shown in FIG. 13C, when the user clicks the “Next Step” icon on the interface shown in FIG. 13C, the handheld gimbal can control the touch display screen to display the video duration setting interface, as shown in FIG. 13D. FIG. 13D shows the video duration setting interface. The user can perform setting operations on the interface shown in FIG. 13D, for example, sliding up and down on the minute value icon and the second value icon of the interface to set the duration. For example, when the user stops sliding, correspondingly, the handheld gimbal can determine the video duration according to the user's setting operation on the interface shown in FIG. 13D, for example, 1 minute and 2 seconds. When the user clicks the “Start Shooting” icon in the interface shown in FIG. 13D, the handheld gimbal can control the follow focus motor according to the focal length 30 and the focal length 50 to drive the lens to zoom, and control the shooting equipment to take 1 minute 2 seconds of video.

Therefore, through the above method, it can be possible to achieve sliding zoom shooting within the video duration set by the user.

Optionally, the shooting target is selected by the user.

Optionally, the handheld gimbal is in communication connection with the shooting equipment. For example, the handheld gimbal is directly connected to the shooting equipment through communication, or the handheld gimbal is connected to the shooting equipment through other devices (such as image transmission equipment). The shooting target is determined by detecting the user's selection operation on the touch screen displaying the shooting image of the shooting equipment.

In some of the above embodiments, the distance sensor is detachably arranged on the shooting equipment, or the distance sensor is detachably arranged on the bearing base of the handheld gimbal.

In some of the above embodiments, the follow focus motor is detachably carried on the bearing base.

In some other embodiments, the present disclosure provides a solution for realizing rotation shooting. This rotation shooting can capture the visual effect of screen rotation. This kind of rotation shooting can be called a space-time tunnel shooting solution. Specifically, the touch display screen of the handheld gimbal is controlled to display a first setting interface for rotation shooting. The first setting interface can be used to set the shooting interval for rotation shooting, detect the user's shooting interval setting operation on the touch screen, and determine the target shooting interval according to the detected shooting interval setting operation.

Optionally, the touch display screen of the handheld gimbal can be controlled to display the second setting interface of the time-space tunnel. The second setting interface can be used to set the video duration of the rotation shooting, detect the video duration setting operation on the touch display screen by the user, and determine the target video duration according to the detected video duration setting operation.

Optionally, the touch display screen of the handheld gimbal can display the third setting interface of the time-space tunnel. The third setting interface can be used to set the starting position of the rotation shooting, detect the starting position setting operation on the touch display screen by the user, and determine the target starting position according to the detected starting position setting operation.

Optionally, the touch screen of the handheld gimbal can be controlled to display the fourth setting interface for rotation shooting. The fourth setting interface can be used to set the rotation angle of the rotation shooting, detect the rotation angle setting operation on the touch display screen by the user, and determine the target rotation angle according to the detected rotation angle setting operation.

It should be noted that some embodiments of the present disclosure do not limit the sequence of determining the target shooting interval, target video duration, target starting position, and target rotation angle.

Then, the pitch axis motor of the handheld gimbal can be controlled to drive the bearing base so that the optical axis of the shooting equipment carried by the bearing base is parallel to the rotation axis of the yaw axis motor (the yaw axis of the handheld gimbal). Then, the rotation of the yaw axis motor can be controlled according to the target starting position, so that the shooting equipment rotates to the target starting position. After the shooting equipment is rotated to the target starting position, the yaw axis motor can be controlled to rotate according to the target rotation angle, so that the shooting equipment rotates the target rotation angle. In the process of controlling the rotation of the yaw axis motor according to the target rotation angle, the shooting equipment can be controlled to shoot images every interval of the target shooting interval to obtain a video of the target video duration. Wherein, in the process of controlling the rotation of the yaw axis motor according to the target rotation angle, the optical axis of the shooting equipment and the rotation axis of the yaw axis motor (the yaw axis of the handheld gimbal) can remain parallel.

Therefore, in one embodiment of the present disclosure, the setting interface can be displayed on the touch display screen of the handheld gimbal to determine the above parameters. Then, according to the above parameters, the yaw axis motor can be controlled to rotate and the shooting equipment can be controlled to shoot video, which can realize automatic rotation shooting, simplify the user's operation, and/or improve the user's experience.

Hereinafter, the above solution is illustrated by taking the example shown in FIGS. 14A-14D. The first setting interface and the second setting interface are, for example, the same interface, and the third setting interface and the fourth setting interface are, for example, the same interface. When the user performs the operation of selecting rotation shooting, the touch display screen can be controlled to display an interface as shown in FIG. 14A, which is used to represent the setting of the shooting interval and video duration of the rotation shooting. When the user clicks on the area representing the shooting interval and video duration in the interface shown in FIG. 14A, the touch display screen can be controlled to display the interface shown in FIG. 14B. The user can perform setting operations on the interface shown in FIG. 14B, such as sliding up and down the numeric icon of the shooting interval to set the shooting interval required by the user (for example, 2 s), and sliding up and down the numeric icon of the video duration to set the video duration required by the user (for example, 30 s). When the user clicks the return icon in the interface shown in FIG. 14B, the touch display screen can be controlled to display as FIG. 14A. Optionally, the interface shown in FIG. 14A can also be used to display the frame per second (FPS) of the screen. When the user clicks on the numerical icon representing FPS, the number of adjacent frames can be switched in turn, for example, among 24, 25, 30, and 60.

When the user clicks on the “Next Step” icon in the interface shown in FIG. 14A, the touch screen can be controlled to display the interface shown in FIG. 14C, which can be used to set the starting position and rotation angle of rotation shooting. When the user clicks on the icon representing the starting position in the interface shown in FIG. 14C, the touch screen can be controlled to display the interface shown in FIG. 14D. The user can perform setting operation on the interface shown in FIG. 14D, such as clicking on the decrease icon or increase icon representing the value of the starting position to set the starting position required by the user (for example, 0°). When the user clicks the return icon in the interface shown in FIG. 14D, the touch screen can be controlled to display as FIG. 14C.

When the user clicks on the icon representing the rotation angle in the interface shown in FIG. 14C, the touch display screen can be controlled to display the interface shown in FIG. 14E. The user can set the interface shown in FIG. 14E. In FIG. 14E, the rotation angle can be determined by the rotation direction and the number of rotations. For example, the user can slide the icon of the rotation direction up and down to set the rotation direction required by the user, and slide up and down the numerical icon of the number of rotations to set the number of rotations required by the user (for example, 1 rotation). When the user clicks the return icon in the interface shown in FIG. 14E, the touch display screen can be controlled to display as FIG. 14C.

When the user clicks the “Start Shooting” icon in the interface shown in FIG. 14C, referring to FIG. 2, the handheld gimbal 100 can control the pitch axis motor 1021 to rotate, so that the optical axis of the shooting equipment carried by the bearing base 1024 is parallel to the rotation axis of the yaw axis motor 1023. Where the starting position is 0°, it can mean that the starting position is the current position of the yaw axis motor 1023. Then, the optical axis of the shooting equipment can be kept parallel to the rotation axis of the yaw axis motor 1023, control the rotation of the yaw axis motor 1023 to drive the shooting equipment to rotate in a clockwise direction, and in the process of rotating, control the shooting equipment to take a picture every 2 s to obtain a 30 s-long video with a rotation shooting effect.

It should be noted that any of the foregoing embodiments can be implemented separately, or can be implemented in any combination of at least two of the foregoing embodiments, which is not limited.
