Description

Technical Field

[0002] In the process of using multimedia devices for remote demonstrations, it is generally necessary to use acquisition modules such as cameras to collect product information or speaker information, and then transmit the collected information to the audience through output modules, such as transmitting the visual information collected by the camera to the audience through a monitor, in order to achieve the purpose of product demonstration.

[0003] In related technologies, multimedia devices have poor adaptability to changes in display scenarios. For example, when a speaker changes position, their field of vision may be lost; when the audience changes position, they may not be able to receive the displayed information well; when it is necessary to change the product display angle, staff need to frequently move the acquisition / output modules or products to adjust their relative positions and postures, which is quite cumbersome. Moreover, multimedia devices in related technologies also have the problem of being inconvenient to store. Summary of the Invention

Therefore, the multimedia device provided in this application embodiment can improve the adaptability of the multimedia device to the switching of display scenes and improve the convenience of storing the multimedia device.

[0033] Please refer to Figure 1 , Figure 2 and Figure 3The acquisition / output module in this application can be implemented in various forms. In some embodiments of this application, the acquisition / output module may include one or more of a camera, microphone, speaker, display, and projection module. The camera may be an autofocus camera. In some embodiments of this application, the acquisition / output module is detachably connected to the adjustment structure. This structural design allows operators to replace the acquisition / output module according to different scenarios.

[0034] Please refer to Figure 1 , Figure 2 and Figure 3 The control module in this application can be implemented in various forms. In some embodiments of this application, the control module can refer to a central processing unit, an embedded controller, or a microcontroller, etc.

[0035] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the operating parameters of the acquisition output / module may include sampling parameters and / or output parameters. Sampling parameters may include one or more of the following: sampling angle, sampling distance range, sampling rate, and sampling resolution; output parameters may include output direction, output angle, output distance range, amplitude or frequency of the output signal, etc.

[0036] Please refer to Figure 1 , Figure 2 and Figure 3 The multimedia device in this application can output target multimedia data in various ways. For example, in some embodiments of this application, the collected target multimedia data can be output to other electronic devices, or the target multimedia data can be output to a target object or to a target location / area through an output module.

[0037] Please refer to Figure 1 , Figure 2 and Figure 3 In this application embodiment, the supporting body 1, used to place the multimedia device on a supporting surface, can be implemented in various ways. For example, in some embodiments of this application, the supporting body 1 can be fixed to the supporting surface, or the supporting body 1 can be movably positioned on the supporting surface relative to the supporting surface via a movable device. For example, the end of the supporting body 1 closest to the supporting surface can be provided with pulleys or casters, etc. To facilitate the movement of the multimedia device, in some embodiments of this application, the end of the supporting body 1 furthest from the supporting surface has a handle 6. This application embodiment does not limit the relative positional relationship between the supporting body 1 and the supporting surface. For example, the supporting body 1 can abut against the supporting surface in a vertical direction or in a horizontal direction, etc.

[0038] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the supporting body 1 further includes at least one support portion 11 disposed near one end of the supporting surface. The support portion 11 can have different orientations relative to the supporting body 1, so that the supporting body 1 has a first structural form and a second structural form. In the first structural form, the contact area between the supporting body 1 and the supporting surface is larger than the contact area between the supporting body 1 and the supporting surface in the second structural form. When the multimedia device is in use, the supporting body 1 is in either the first or second structural form; when the multimedia device is in a stored state, the supporting body 1 is in the second structural form. With this structural configuration, when the supporting body 1 is in use, it can be in the first structural form, with a larger contact area between the support portion 11 and the supporting surface, making the placement of the multimedia device on the supporting surface more stable. When the multimedia device is in a stored state, the supporting body 1 is in the second structural form, with a smaller contact area between the support portion 11 and the supporting surface, thus minimizing the space occupied by the support portion 11.

[0039] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the supporting body 1 includes a support portion 11 and a supporting body body. The supporting body body is column-shaped, and the column can be hexahedral or cylindrical. An adjustment structure is movably mounted on the supporting body body. The extending direction of the support portion 11 is perpendicular to the supporting direction of the bearing surface of the support portion 11.

[0040] Please refer to Figure 1 , Figure 2 and Figure 3 For ease of description, the support direction between the supporting body 1 and the supporting surface will be referred to as the support direction. The supporting part 11 and the supporting body 1 are arranged perpendicular to the support direction. The supporting part 11 and the supporting body 1 are rotatably connected. The axis of relative rotation between the supporting part 11 and the supporting body 1 forms an angle with the support direction, allowing the supporting part 11 to change its contact area with the supporting surface, thereby enabling the supporting body 1 to be in either a first structural configuration or a second structural configuration. In some embodiments of this application, one end of the supporting part 11 is perpendicular to the axis of relative rotation between the supporting body 1 and the support direction.

[0041] Please refer to Figure 1 , Figure 2 and Figure 3In some embodiments of this application, there may be multiple support portions 11, arranged around the support body 1. These multiple support portions 11 may be evenly or unevenly arranged around the support body 1. This structural configuration helps improve the stability of the support body 1 when placed on the support surface. In some embodiments of this application, the support portions 11 extend radially perpendicular to the extending direction of the support body 1. This structural configuration also helps improve the stability of the support body 1 when placed on the support surface.

[0042] Please refer to Figure 1 , Figure 2 and Figure 3 Of course, the implementation of the support part 11 is not limited to this. In some other embodiments of this application, the support part 11 may slide relative to the bearing body 1 in the vertical direction of the support direction to move closer to and away from the bearing body 1, so that the bearing body 1 is in the first structural form and the second structural form, etc.

[0043] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the multimedia device further includes a carrying structure 3 movably connected to the supporting body 1. The carrying structure 3 can have different poses relative to the supporting body 1 and can have different structural forms based on changes in pose. The carrying structure 3 is used to place a target item. A control module is signal-connected to the carrying structure 3, and the control module can control the target relative positional relationship between the carrying structure 3 and the adjustment structure, so as to obtain target multimedia data that can be output externally using the multimedia device's acquisition module. With this structural form, the control module can adjust the pose of the carrying structure 3 to adjust the relative pose between the acquisition / output module and the target item, enabling the multimedia device to more comprehensively acquire information about the target item, thereby allowing the multimedia device to better adapt to changes in the display scene.

[0044] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the control module can control the synchronous movement of the carrying structure 3 and the adjustment structure, or it can control only one of them, so that the two have a target relative positional relationship, in order to better collect information about the target item located on the carrying structure 3. It is understood that the target relative positional relationship between the carrying structure 3 and the adjustment structure can be different for different target items.

[0045] Please refer to Figure 1 , Figure 2 and Figure 3In this embodiment, the carrying structure 3 can have different poses relative to the supporting body 1, which can be implemented in various ways. For example, the carrying structure 3 can rotate or translate relative to the supporting body 1 to be in different positions. Translational movement can be along the support direction, along the direction perpendicular to the support direction, along the acquisition / output module's acquisition direction, or along the direction perpendicular to the acquisition / output module's acquisition direction, etc. The axis of rotational movement can be parallel to the support direction, parallel to the direction perpendicular to the support direction, parallel to the acquisition / output module's acquisition direction, or parallel to the direction perpendicular to the acquisition / output module's acquisition direction, etc. When there are multiple acquisition / output modules, the acquisition direction of the acquisition / output modules in this embodiment can be the acquisition direction of any acquisition / output module.

[0046] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the carrying structure 3 can change its occupied space by being in different positions. When the multimedia device is in use, the carrying structure 3 occupies a larger space, and when the multimedia device is in storage, the carrying structure 3 occupies a smaller space. For example, in some embodiments of this application, the carrying structure 3 can be translated to different positions to adjust the distance between the supporting body 1 and the carrying structure 3.

[0047] In some embodiments of this application, the arrangement direction of the carrying structure 3 and the supporting body 1 is a first direction, which is parallel to the supporting surface. The end of the carrying structure 3 closest to the supporting body 1 along the first direction is rotatably connected to the supporting body 1. The axis of relative rotation between the carrying structure 3 and the supporting body 1 forms an angle with the first direction, thereby changing the space occupied by the carrying structure 3. In some embodiments of this application, the supporting body 1 is provided with a groove, and the carrying structure 3 can be at least partially housed within the groove through rotational movement relative to the supporting body 1.

[0048] In some embodiments of this application, the axis of rotation between the carrier structure 3 and the supporting body 1 is perpendicular to the first direction. In some embodiments of this application, the first direction is the same as the acquisition direction of the acquisition / output module. In some embodiments of this application, the carrier structure 3 can be supported on the supporting surface along the support direction. This structural form is beneficial to improving the stability of the multimedia device placement.

The first telescopic component 31 is capable of various types of movement relative to the supporting body 1, and the carrying platform 32 is capable of at least one type of movement relative to the first telescopic component 31, so that the carrying structure 3 has different postures relative to the supporting body 1. The carrying platform 32 can have a third structural form and a fourth structural form through movement relative to the first telescopic component 31, and the platform area of ​​the carrying platform 32 in the third structural form is larger than its platform area in the fourth structural form. This structural form facilitates the storage of the carrying platform 32.

[0051] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the supporting body 1, the first telescopic component 31, and the loading platform 32 are arranged along a first direction. The first telescopic component 31 is located between the supporting body 1 and the loading platform 32, and extends along the first direction. The first telescopic component 31 is capable of telescopic movement along the first direction to drive the loading platform 32 to move relative to the supporting body 1. In some embodiments of this application, the end of the first telescopic component 31 away from the loading platform 32 is rotatably connected to the supporting body 1 via a flipping mechanism 33, and the direction of relative rotation between the first telescopic component 31 and the supporting body 1 is perpendicular to the first direction. In some embodiments of this application, the direction of relative rotation between the first telescopic component 31 and the supporting body 1 is perpendicular to the support direction.

[0052] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the loading platform 32 and the supporting body 1 are arranged along the acquisition direction of the acquisition / output module. The loading platform 32 includes a first loading element 321 and a second loading element 322. The second loading element 322 can rotate relative to the first loading element 321 or rotate in a direction perpendicular to the acquisition direction of the acquisition / output module. The second loading element 322 is used to place the target item. This structural form allows the acquisition / output module to acquire information about the target item from multiple directions. In some embodiments of this application, the first loading element 321 can be fixed to the end of the first telescopic component 31 away from the supporting body 1.

[0053] Please refer to Figure 1 , Figure 2 and Figure 3In this embodiment, the adjustment structure can be implemented in various ways. The adjustment structure is used to enable the acquisition / output module to rotate, translate, or perform a combination of rotation and translation relative to the supporting body 1.

The direction of translational movement of the acquisition / output module relative to the supporting body 1 can be parallel to or perpendicular to the support direction. The axis of rotation of the acquisition / output module relative to the supporting body 1 can be parallel to or perpendicular to the acquisition or output direction of the acquisition / output module. The axis of rotational movement of the acquisition / output module relative to the supporting body 1 can be parallel to or perpendicular to the support direction.

The first adjustment structure 4 includes a first connector connected to a first support portion of the support body 1, a second telescopic component connected to the first connector, and a first mounting portion disposed at the free end of the second telescopic component for mounting a data acquisition / output module. The first connector can perform a first type of movement relative to the support body 1 via the first support portion, and the second telescopic component can perform a second type of movement relative to the support body 1, so that the first adjustment structure 4 can have different poses relative to the support body 1. The data acquisition / output module can have different relative positions relative to the adjustment structure via the first mounting portion. Alternatively, the second adjustment structure includes a second connector connected to a second support portion of the support body 1, and a second mounting portion disposed on the second connector. The second connector can perform a first type of movement or a third type of movement relative to the support body 1 via the second support portion, so that the second adjustment structure can have different poses relative to the support body 1. The data acquisition / output module can have different relative positions relative to the adjustment structure via the second mounting portion. With this structural configuration, the data acquisition / output module can be adjusted over a wide range.

[0055] Please refer to Figure 1 , Figure 2 and Figure 3In some embodiments of this application, the multimedia device includes a first acquisition / output module 21, which is used to capture images of a target object. The acquisition direction of the first acquisition / output module 21 is a second direction a. A first connector includes a first connecting arm 41, the first end of which is rotatable or slidable relative to the supporting body 1, and has a distance from the first acquisition / output module 21 in a third direction b. The second direction a is perpendicular to the third direction b, and the axis of rotation of the first connecting arm 41 relative to the supporting body 1 forms an angle with the second direction a, so that the second end of the first connecting arm 41 can move closer to or further away from the first acquisition / output module 21 in the second direction a. The multimedia device also includes a second acquisition / output module 22, which is used to capture images of the target object and is disposed on the second end of the first connecting arm 41.

Furthermore, the second end of the first connecting arm 41 can move closer to or further away from the first acquisition / output module 21 in the second direction a, enabling the multimedia device to switch between a use state and a storage state. In some embodiments of this application, the axis of rotation of the first connecting arm 41 relative to the supporting body 1 is perpendicular to the second direction a. This structural form is beneficial for improving the compactness of the structure. In some embodiments of this application, when the multimedia device is in use, the first connecting arm 41 can be moved to a position perpendicular to the third direction b.

[0056] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the second telescopic component includes a first telescopic arm 42, one end of which is rotatably connected to the second end of a first connecting arm 41.

[0070] Secondly, embodiments of this application provide a control method applied to a multimedia device. The method includes: in response to obtaining a target instruction, obtaining the relative positional relationship between the acquisition / output module of the multimedia device and the target object; controlling the pose of the adjustment structure of the multimedia device and / or the operating parameters of the acquisition / output module based on the relative positional relationship, so that the multimedia device can output target multimedia data; wherein, the target multimedia data includes data of the target object or data directed to the target object.

[0071] Please refer to Figure 4 The control method includes:

[0072] S101, in response to the target acquisition instruction, obtains the relative positional relationship between the acquisition / output module of the multimedia device and the target object;

[0073] S102 controls the pose of the adjustment structure of the multimedia device and / or the working parameters of the acquisition / output module based on the relative position relationship, so that the multimedia device can output target multimedia data to the outside world.

[0074] In this way, the adjustment structure can have different poses relative to the supporting body 1 based on the relative positional relationship between the acquisition / output module and the target object. The acquisition / output module is positioned on the corresponding adjustment structure, allowing the control module to adjust the pose of the acquisition / output module by changing the pose of the adjustment structure based on the relative positional relationship, thus better adapting to the switching of display scenes. Furthermore, the control module can also adjust the operating parameters of the acquisition / output module, further improving the multimedia device's adaptability to display scene switching.

[0075] In this embodiment, the target object can take many forms. For example, the target object can refer to a person or an item. A person can be a speaker, a product presenter, a host, etc., and an item can be a display item, an item located on the loading platform 32, etc.

[0076] For example, in some embodiments of this application, the target object is the speaker, the acquisition / output module includes a camera, and the control module can adjust the camera's orientation or focal length according to the relative positional relationship between the camera and the speaker. For instance, if the speaker moves within the venue, the camera can move with the speaker under the control of the control module and adjust its focal length to obtain better image quality. In some embodiments of this application, the control module can determine the magnitude of the adjustment based on the target instruction, and adjust the pose of the acquisition / output module by changing the pose of the adjustment structure, or by adjusting the operating parameters of the acquisition / output module to acquire or output target multimedia data. For example, if the adjustment magnitude is large, the pose of the acquisition / output module is adjusted by changing the pose of the adjustment structure to acquire or output target multimedia data; if the adjustment magnitude is small, the operating parameters of the acquisition / output module are adjusted to acquire or output target multimedia data, thereby achieving rapid and precise adjustment. For example, in some embodiments of this application, the acquisition / output module includes a camera, and the camera's pose is changed when the adjustment magnitude is large, and the camera's pose focal length is changed when the adjustment magnitude is small.

[0077] In other embodiments, the pose of the structure or the working parameters of the target acquisition module can be controlled and adjusted according to the positional relationship between the item to be displayed and the acquisition module placed on the carrying platform of the supporting structure, the structural shape of the item to be displayed, etc., so as to obtain target multimedia data that can be output externally.

[0078] In some embodiments of this application, obtaining a target instruction includes at least one of the following: in response to obtaining a request content from a control device, generating a target instruction based on the request content, wherein the control device is an output device.

[0079] The device that outputs target multimedia data requests content based on input operations performed on the input components of the control device; generates target instructions in response to detecting a change in the target object; and generates target instructions in response to receiving target data input.

[0080] Please refer to Figure 5 The control method includes:

[0084] And / or,

[0085] S202, in response to detecting a change in the target object, generate a target instruction;

[0086] S204, in response to the target acquisition command, acquires the acquisition / output module of the multimedia device and the target object.

[0088] 0S205, based on relative positional relationships, controls the pose and / or acquisition / transmission of the adjustment structure of a multimedia device.

[0089] The module's operating parameters are output so that the multimedia device can output target multimedia data.

[0090] And / or,

[0091] S203, in response to receiving target data input, generates target instructions;

[0092] S204, in response to the target acquisition command, obtain the relative positional relationship between the acquisition / output module of the multimedia device and the target object 5;

[0093] S205 controls the pose of the adjustment structure of the multimedia device and / or the working parameters of the acquisition / output module based on the relative positional relationship, so that the multimedia device can output target multimedia data to the outside world.

[0094] The requested content is generated based on input operations performed on the input components of the control device. These input operations can include touch operations and keyboard / mouse operations on the control device's display interface, as well as voice input, gesture input, string input, and gaze control. The requested content includes adjustments to the displayed content's angle, graphic model reconstruction, focus adjustment, scaling, target object switching, and more.

[0095] For example, in some embodiments of this application, the target object is an item, the acquisition / output module includes a camera, the user adjusts the relative positional relationship between the item and the camera through input operations, the control module obtains the target instruction after the user's input operation, obtains the adjusted relative positional relationship between the camera and the item, and adjusts the camera focal length according to the relative positional relationship to obtain a better imaging effect.

[0096] In some embodiments of this application, users can adjust the relative position of an object and a camera by inputting an operation to adjust the display angle of the object. The input operation can be the user rotating or moving the virtual model corresponding to the object on the touch screen. The input operation is called a target instruction. The control module adjusts the camera focal length adjustment structure and / or the phase position of the camera module and the platform or the object to be displayed, or the acquisition parameters of the camera module, etc., based on the adjusted relative position of the camera and the object, to obtain image data of the target angle.

[0097] Changes to the target object can occur, such as object switching, object disappearance, or a change in location.

[0098] For example, in some embodiments of this application, the target object is the speaker, the acquisition / output module includes a camera, and the control module acquires the relative positional relationship between the camera and the speaker when the speaker changes or moves, and adjusts the camera focal length, etc., according to the relative positional relationship to obtain better video recording effect.

[0099] In response to receiving target data input, a target instruction is generated. The target data input may include data generated by the target object, such as voice or gestures; the target data may also be triggered by preset keywords, preset voiceprint data, etc. For example, in some embodiments of this application, the target object is an item, the acquisition / output module includes a camera, and the control module acquires the target instruction after obtaining voice or gesture information, acquires the relative positional relationship between the camera and the item, and adjusts the camera focal length according to the relative positional relationship to obtain better image quality.

[0100] In some embodiments of this application, controlling the pose of the adjustment structure of a multimedia device and / or the operating parameters of the acquisition / output module based on relative positional relationships includes at least one of the following: controlling multiple adjustment structures of the multimedia device to move synchronously or asynchronously to a pose with a target relative positional relationship to the target object based on relative positional relationships; if the relative positional relationship satisfies a first control condition, controlling multiple adjustment structures of the multimedia device to move synchronously or asynchronously to a pose with a target relative positional relationship to the target object; if the relative positional relationship satisfies a second control condition, adjusting the operating parameters of the acquisition / output module.

[0101] Please refer to Figure 6 The control method includes:

[0102] S301, in response to the target acquisition command, acquires the relative positional relationship between the acquisition / output module of the multimedia device and the target object;

[0103] S302, based on the relative positional relationship, controls multiple adjustment structures of a multimedia device to move synchronously or asynchronously to a pose with a target relative positional relationship with the target object.

[0104] For example, in some embodiments of this application, the target object is an object, the acquisition / output module includes a camera, and the user adjusts the relative positional relationship between the object and the camera through input operations. The control module obtains the target instruction after the user's input operation, acquires the adjusted relative positional relationship between the camera and the object, and adjusts the poses of multiple adjustment structures according to the relative positional relationship. Multiple adjustment structures may move synchronously to a preset pose. Alternatively, one adjustment structure may first move to a first preset pose, then the control module acquires the relative positional relationship between the camera and the object, and then controls another adjustment structure to move to a second preset pose.

[0105] Please refer to Figure 7 The control method may also include:

[0106] S401, in response to the target acquisition command, acquires the relative positional relationship between the acquisition / output module of the multimedia device and the target object;

[0107] S402, the relative positional relationship satisfies the first control condition;

[0108] S403, if so, control multiple adjustment structures of the multimedia device to move synchronously or asynchronously to a pose with a target relative positional relationship with the target object based on the relative positional relationship.

[0109] Please refer to Figure 8 The control method may also include:

[0110] S501, in response to the target acquisition command, acquires the relative positional relationship between the acquisition / output module of the multimedia device and the target object;

[0111] S502, the relative positional relationship satisfies the second control condition;

[0112] S503, if so, adjust the operating parameters of the acquisition / output module.

[0113] In some embodiments of this application, the first control condition can be an adjustment range, and the second control adjustment can be a smaller adjustment range. For example, the control module can determine the magnitude of the adjustment range according to the target instruction, and adjust the pose of the acquisition / output module by changing the pose of the adjustment structure, or acquire or output target multimedia data by adjusting the operating parameters of the acquisition / output module. For example, if the adjustment range is large, the target multimedia data can be acquired or output by adjusting the pose of the acquisition / output module by changing the pose of the adjustment structure; if the adjustment range is small, the target multimedia data can be acquired or output by adjusting the operating parameters of the acquisition / output module, thereby achieving rapid and precise adjustment. Exemplarily, in some embodiments of this application, the acquisition / output module includes a camera; if the adjustment range is large, the camera's pose is changed; if the adjustment range is small, the camera's pose focal length is changed.
