The method of an embodiment of the present invention includes the following steps.
S201: acquiring shooting control parameters, wherein the shooting control parameters comprise rotation parameters of a rotating shaft of the holder equipment and target shooting parameters of the shooting equipment, and the shooting equipment is hung on the holder equipment.
The shooting control parameters may be set directly on the control device. In an embodiment, the control device may be an intelligent terminal with a touch screen, an APP with a user interface is run on the control device, shooting control parameters set by a user are received through the user interface, and subsequent control processing is executed after processing is performed through the APP. In one embodiment, the rotation parameter includes any one or more of a rotation start angle, a rotation end angle, a rotation speed, a rotation time period, and a rotation direction. The target shooting parameters comprise any one or more of zooming parameters, focus following parameters and exposure parameters.
In one embodiment, as shown in fig. 3, is a schematic diagram of a user interface of an embodiment of the present invention, on which a first setting area 301 for setting a selection parameter of a rotation axis of a pan/tilt apparatus, a second setting area 302 for setting a shooting parameter of a shooting apparatus, and a third setting area 303 for setting an intermediate parameter are included. Wherein the third setting region 303 is used for setting a rotation intermediate angle of the rotation axis and for setting an intermediate photographing parameter of the photographing apparatus. The rotation intermediate angle includes one or more angles, and the intermediate photographing parameters include one or more photographing parameters. It should be noted that the third setting region 303 is optional. In one embodiment, the user interface may further include an intermediate photographing parameter setting option, and the third setting region 303 is displayed when a user's clicking operation with respect to the intermediate photographing parameter setting option is detected. In one embodiment, the third setting region 303 is displayed when it is detected that the respective intermediate parameters of the corresponding rotation parameter or photographing parameter need to be set. Otherwise, the third setting region 303 is not displayed. A button may be provided which, upon detecting that the user has clicked on this button, indicates that the user wishes to set an intermediate parameter, and the third setting area 303 is displayed.
As shown in fig. 3, in the first setting section 301, the user may select one or more target rotation axes to be rotated from among the Pitch axis, the Roll axis, and the Yaw axis, may set a rotation direction, including selecting a clockwise rotation direction or a counterclockwise rotation direction, and may set a selected rotation start angle and a selected rotation end angle. In other embodiments, the first setting area 301 may further include a setting of the rotation speed, or a setting of the rotation time period. Based on the set rotation speed (an angular speed), the corresponding target rotation axis may be controlled to rotate at a constant speed between the rotation start angle and the rotation end angle according to the rotation speed. Based on the set rotation duration, the corresponding target rotation shaft may be controlled to rotate at a constant speed or a discrete speed at the rotation start angle and the rotation end angle, but the duration consumed from the rotation start angle to the rotation end angle is the same as the set rotation duration. In an embodiment, a confirmation switch may be further disposed in the first setting area 301, and after the setting of one rotation axis is completed, the confirmation switch may be clicked to complete the setting of the one rotation axis, and then the setting of the rotation parameter of the next rotation axis is continued, so as to control the rotation axis corresponding to the pan/tilt apparatus according to the rotation parameter set by one or more rotation axes. For example, after the rotation parameter setting of the Pitch axis is completed and the confirmation button is clicked, the rotation parameter setting of the Roll axis may be selected again, and then the rotation parameter of the Pitch axis and the rotation parameter of the Roll axis may be obtained.
In other embodiments, the setting of the rotation parameters of each rotation axis may also be accomplished by setting physical keys and knobs, for example, by using knobs, the directions and angles of rotation of which correspond to the respective rotation axes.
As also shown in fig. 3, the second setting area 302 may set the shooting parameters of the shooting device, which mainly includes setting the zoom parameters, that is, setting the starting focal length and the ending focal length on the second setting area 302, so that the focal length can be changed between the starting focal length and the ending focal length in the video shooting process, thereby achieving the effects of zooming out and zooming in; setting focus following parameters, namely setting a starting focus and an ending focus on the second setting area 302, wherein the setting of the focus can be quantified by 1% to 100%, so as to achieve the effect of gradually clear and fuzzy shot video, or ensure that when a certain shot object, such as a person, is close to or far away from a lens, the focus can be determined by a target object, and ensure that the shot target object is clear; the exposure parameters are set, that is, the starting exposure and the ending exposure are set on the second setting area 302, so that the shot video can be performed under different exposures, and the effect that the brightness of the video frame gradually changes is achieved. Further, in other embodiments, various other settable shooting parameters such as the delay shooting mode and the video shooting mode may be set as needed. In S201, only some shooting parameters may be set, and the set corresponding shooting parameters are used as target shooting parameters, for example, only zoom parameters are set, the target shooting parameters are zoom parameters, and other shooting parameters are based on current corresponding parameters of the camera, or default parameters are used, or parameters of intelligent matching are used, for example, after zoom parameters are set, the focus is automatically determined by focusing.
In fig. 3, the combination of the slide button and the slide rail is illustrated, and in other embodiments, the setting of the shooting parameters may be performed by an analog knob or by inputting a specific number. For example, the numbers of 20 and 50 may be entered in the input box of the focal length, corresponding to setting the zoom parameter to vary between 20 mm and 50 mm, etc.
S202: if a shooting starting instruction is detected, controlling the rotating shaft to rotate according to the rotating parameters, adjusting shooting parameters of the shooting equipment according to the target shooting parameters, and shooting a video; wherein the shooting equipment shoots videos in the processes of shooting parameter adjustment and rotation of the rotating shaft.
After the rotation parameters and the target shooting parameters are obtained in S201, the pan-tilt apparatus and the shooting apparatus can be controlled respectively. Once the shooting start instruction is detected, the rotation angle, the rotation direction and/or the rotation time length of the corresponding rotation shaft on the pan-tilt device are correspondingly adjusted through the rotation parameters, and the zoom parameters, the focus following parameters and/or the exposure parameters of the shooting device are correspondingly adjusted through the target shooting parameters. After the user interface shown in fig. 3 sets the rotation parameters and the shooting parameters, the rotation angles of the rotation shafts corresponding to the time nodes are different and/or the shooting parameters corresponding to the time nodes are different in the video shooting process.
The purpose of rotatably shooting the video on any one or more axes of a Pitch axis, a Yaw axis and a Roll axis is achieved through independent control of the rotating shaft, and the video effect of rotary shooting is achieved. The aim of video shooting under any one or more of different focal lengths, different focuses and different exposure amounts is fulfilled by independently controlling shooting parameters of the shooting equipment, so that a video effect that a lens is zoomed out or zoomed in is realized, a video effect that changes between fuzzy and clear is realized, and a video effect that changes between bright and dark is realized. Other video effects may also be achieved in combination, such as zoom control while the effect of rotational capture is achieved on the Roll axis to achieve zoom-out and/or zoom-in video effects simultaneously.
In one embodiment, the control device may establish communication connection with the pan/tilt apparatus and the shooting device, respectively. The control equipment can generate a rotation control command in real time based on the rotation parameter and the target shooting parameter set by the user, send the rotation control command to the holder equipment to control the holder equipment in real time, and generate a shooting control command in real time, send the shooting control command to the shooting equipment to control the shooting equipment in real time. Specifically, the control device sends a rotation control instruction to the pan and tilt device, the rotation control instruction is obtained according to the rotation parameter, and the rotation control instruction is used for instructing the pan and tilt device to control the rotation shaft to rotate according to the rotation parameter. And the control equipment sends a shooting control instruction to the shooting equipment, the shooting control instruction is generated according to the target shooting parameters, and the shooting control instruction is used for instructing the shooting equipment to adjust the shooting parameters according to the target shooting parameters.
The control device can also directly send the rotation parameters and the target shooting parameters to the holder device and the shooting device in real time, the holder device directly controls the rotation of the rotating shaft based on the rotation parameters, and the shooting device directly controls shooting based on the target shooting parameters, such as automatic focus following based on focus following parameters, automatic zooming based on zooming parameters, and the like.
In one embodiment, the control device may transmit the target photographing parameters or the photographing control instruction to the photographing device through the pan and tilt device. Specifically, the control device sends a shooting control instruction to the pan and tilt device, the shooting control instruction is generated according to the target shooting parameters, and the shooting control instruction is used for instructing the pan and tilt device to send the shooting control instruction to the shooting device so that the shooting device can adjust the shooting parameters according to the target shooting parameters. And the cloud deck equipment is in communication connection with the shooting equipment, and the shooting equipment adjusts the shooting parameters according to the target shooting parameters after receiving the shooting control instruction sent by the cloud deck equipment. The control equipment sends an instruction carrying target shooting parameters to the holder equipment, and the instruction is used for instructing the holder equipment to send the target shooting parameters to the shooting equipment so that the shooting equipment can carry out shooting parameter adjustment according to the target shooting parameters. And after receiving the target shooting parameters sent by the holder equipment, the shooting equipment adjusts the shooting parameters according to the target shooting parameters.
In one embodiment, the adjustment of the shooting parameters of the shooting device can be realized by a parameter adjusting device, that is, the control device can control the shooting parameter adjusting device to adjust the shooting parameters of the shooting device according to the target shooting parameters. As described above, the parameter adjusting device may be a controllable device with an electric motor, and the parameter adjusting device adjusts the shooting parameters such as the focal length and/or focus of the shooting device by driving the components such as the zoom ring and the focus ring of the shooting device.
When the target shooting parameters are set, the shooting parameter change speed or the shooting parameter adjusting duration of the target shooting parameters can be set as required, and the target shooting parameters such as focal length, focus or exposure can be changed at a constant speed based on the shooting parameter change speed; or after the shooting parameter adjusting time length is obtained, determining the shooting parameter change characteristics according to the target shooting parameters and the shooting parameter adjusting time length; adjusting the shooting parameters of the shooting equipment according to the shooting parameter change characteristics, wherein the shooting parameter change characteristics can be focal length change speeds obtained by calculating the shooting parameter adjustment duration, the initial focal length and the end focal length; or the shooting parameter change characteristic can be a focus change speed obtained by calculating according to the shooting parameter adjusting duration, the starting focus and the ending focus; or the shooting parameter change characteristic can be an exposure change speed calculated according to the shooting parameter adjusting duration, the initial exposure and the ending exposure.
In one embodiment, the time at which the rotation axis of the pan/tilt apparatus starts rotating may be different from the time at which the photographing apparatus starts adjusting the photographing parameters; the time when the rotation shaft of the pan/tilt apparatus finishes rotating may be different from the time when the photographing apparatus finishes adjusting the photographing parameters. For example, after the rotating shaft of the pan-tilt apparatus starts to rotate for a first preset time, the shooting apparatus starts to adjust the shooting parameters; after the rotating shaft of the holder device finishes rotating, the shooting device can also continue to adjust the shooting parameters, and after the rotating shaft of the holder device finishes rotating for a second preset time, the shooting device stops adjusting the shooting parameters. It should be noted that the time when the rotation axis of the pan/tilt head device starts to rotate and the time when the rotation axis of the pan/tilt head device ends to rotate, the time when the photographing device starts to adjust the photographing parameters, and the time when the photographing device ends to adjust the photographing parameters may be set by the user of the control device when setting the photographing control parameters.
In another embodiment, the time when the rotation axis of the pan/tilt apparatus starts to rotate may be the same as the time when the photographing apparatus starts to adjust the photographing parameters; the time when the rotating shaft of the holder device finishes rotating can be the same as the time when the shooting device finishes adjusting the shooting parameters; in other words, the rotation axis of the pan/tilt apparatus rotates in synchronization with the adjustment of the shooting parameters of the shooting apparatus. In other embodiments, the target photographing parameter may have a corresponding relationship with the rotation angle of the rotation axis. For example, the target start shooting parameter corresponds to a rotation start angle, the target end shooting parameter corresponds to a rotation end angle, and the target intermediate shooting parameter corresponds to a rotation intermediate angle.
In one embodiment, if the rotation parameter includes a rotation start angle and a rotation end angle, the control device may control the rotation shaft to be linearly rotated between the rotation start angle and the rotation end angle. In another embodiment, if the rotation parameters include a rotation start angle, a rotation end angle, and a rotation intermediate angle, the control device may control the rotation shaft to linearly rotate between the rotation start angle and the rotation intermediate angle, between the respective rotation intermediate angles, and between the rotation intermediate angle and the rotation end angle.
In one embodiment, the rotation parameter set by the user includes a rotation angle including any one or more of a rotation start angle, a rotation end angle, and a rotation intermediate angle. The intermediate angle of rotation may comprise one or more angles. Wherein the rotation parameters further comprise a plurality of rotation speeds. The plurality of rotation speeds correspond to two rotation angles, respectively. For example, it is assumed that the rotation angle includes a rotation start angle, a rotation end angle, and a rotation intermediate angle, and the rotation speed includes a first rotation speed and a second rotation speed. The first rotation speed corresponds to the start rotation angle and the middle rotation angle, and the second rotation speed corresponds to the middle rotation angle and the end rotation angle. The control device may control the rotation shaft to rotate from the start rotation angle to the rotation intermediate angle at a first rotation speed and from the rotation intermediate angle to the end rotation angle at a second rotation speed. It should be noted that the speed value indicated by the first rotation speed may be fixed or may be variable; the speed value indicated by the second rotational speed may be fixed or may vary.
In another embodiment, the rotation parameter further comprises a plurality of rotation durations. The plurality of rotation durations correspond to the two rotation angles, respectively. For example, assume that the rotation angle includes a rotation start angle, a rotation end angle, and a rotation middle angle, and the rotation duration includes a first rotation duration and a second rotation duration. The first rotation duration corresponds to the initial rotation angle and the middle rotation angle, and the second rotation duration corresponds to the middle rotation angle and the end rotation angle. The control device may control a rotation period of the rotation shaft from the start rotation angle to the middle rotation angle to be the first rotation period and a rotation period of the rotation shaft from the middle rotation angle to the end rotation angle to be the second rotation period.
In another embodiment, the rotation parameters further comprise a plurality of rotation directions. The plurality of rotation directions correspond to two rotation angles, respectively. For example, assume that the rotation angle includes a rotation start angle, a rotation end angle, and a rotation middle angle, and the rotation directions include a first rotation direction (e.g., clockwise) and a second rotation direction (e.g., counterclockwise). The first rotation direction corresponds to the initial rotation angle and the middle rotation angle, and the second rotation direction corresponds to the middle rotation angle and the end rotation angle. The control device may control the rotation shaft to rotate from the start rotation angle to the middle rotation angle in the first rotation direction and from the middle rotation angle to the end rotation angle in the second rotation direction.
In one embodiment, if the target photographing parameters include a target start photographing parameter and a target end photographing parameter, the control device may linearly adjust the photographing parameters of the photographing device between the target start photographing parameter and the target end photographing parameter; that is, the photographing parameters for controlling the photographing apparatus are linearly changed from the target start photographing parameters to the target end photographing parameters. In another embodiment, if the target photographing parameters include a target start photographing parameter, a target end photographing parameter, and a target intermediate photographing parameter, the control device may linearly adjust the photographing parameters of the photographing device between the target start photographing parameter and the target intermediate photographing parameter, between the respective intermediate photographing parameters, and between the target intermediate photographing parameter and the target end photographing parameter. The linear relationship between every two shooting parameters can be the same or different.
In the embodiment of the invention, the rotation parameters and the target shooting parameters are firstly acquired, then the rotating shaft is controlled to rotate according to the rotation parameters, the shooting parameters of the shooting equipment are adjusted according to the target shooting parameters, and the video is shot, wherein the shooting equipment carries out video shooting in the shooting parameter adjusting and rotating processes of the rotating shaft.
