Description

Technical Field

[0001] The present application relates to the technical field of video acquisition equipment, and in particular to a video acquisition conversion device and a video acquisition card for camera live broadcast. Background Art

[0002] Camera movement is a key element in photography, which involves the movement of the camera and the use of the lens to create rich and varied visual effects. Whether it is the basic push, pull, pan, dolly, follow shot, or advanced surround, low angle, lift, pan, etc., they can add unique charm to the work. Push shot is to move the lens closer to the subject from far to near, so that the picture gradually focuses on the subject. This technique is often used for close-ups of people or product displays to highlight the subject and guide the audience's attention. On the contrary, pull shot is to move the lens away from the subject from near to far to show a wider scene. It is often used for opening shots or environment introductions to create a sense of grandeur and space. Pan shot and dolly shot involve the rotation of the lens in the horizontal or vertical direction, and the movement of the camera in the horizontal or vertical direction. Both techniques can describe space, introduce the environment, and show different sides of the subject. Pan shot is often used to shoot large events or landscapes, while dolly shot is suitable for tracking shots or sports scenes.

[0003] However, when the camera is moving during live broadcast, a bracket is usually used to ensure normal camera movement effects. The camera is mounted on the bracket and the camera moves with the bracket during camera movement. However, if multiple camera movement effects are required, multiple brackets are required, which is more troublesome to use. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide a video capture and conversion device and a video capture card for live camera movement to solve the above-mentioned technical problems.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions: a video acquisition and conversion device for live camera movement, including a camera and an adjustment bracket for mounting the camera, the adjustment bracket including a base bracket and a rotating bracket rotatably connected to the base bracket, a sliding bracket for pushing the camera is fixedly provided on the rotating bracket, and a rotating component for driving the rotating bracket to rotate is provided on the base bracket.

[0006] By adopting the above technical solution, the camera can rotate left and right along with the rotating bracket, thereby realizing left and right camera movement, and the sliding bracket can make the camera move forward and backward, thereby realizing forward and backward camera movement.

[0007] Furthermore, a base platform is fixedly provided on the base bracket, and the rotating assembly includes a forward and reverse motor fixedly connected to the base platform, and forward and reverse gears are fixedly provided on the output end of the forward and reverse motor. A circle of placement grooves is provided on the rotating bracket, and driven gears are fixedly provided in the placement grooves, and the forward and reverse gears are meshed with the driven gears.

[0008] By adopting the above technical solution, when moving the mirror left and right, the forward and reverse gears on the motor are driven to rotate by the forward and reverse motor, thereby driving the meshed driven gears on the rotating bracket, thereby driving the rotating bracket to rotate clockwise or counterclockwise, and the rotating bracket is driven by the forward and reverse motor to rotate left and right.

[0009] Furthermore, an extension bracket is installed on the sliding bracket, a rotating bracket is installed at the bottom of the camera, a rotating motor is fixedly arranged at the bottom of the rotating bracket, a rotating gear is fixedly connected on the output end of the rotating motor, a gear bar is fixedly arranged on the extension bracket, the gear bar is meshed with the rotating gear, a sliding rod is fixedly arranged on one side of the rotating bracket, and a long groove matching the sliding rod is provided on the extension bracket.

[0010] By adopting the above technical solution, when it is necessary to move the camera forward and backward, the motor is started by rotating, the output end connection is rotated, the rotating gear rotates, and then engages with the gear bar, driving the bottom of the rotating frame to move in the slide groove on the extension bracket. The rotating motor in this application uses a motor that can rotate forward and reverse, so that the camera on the rotating frame can be moved forward and backward.

[0011] Furthermore, limiting plates fixedly connected to the extension bracket are arranged on both sides of the long groove.

[0012] By adopting the above technical solution, the limiting plates on both sides of the long groove are used to limit the separation of the rotating frame, thereby avoiding affecting the movement of the camera.

[0013] Furthermore, a sliding groove is provided on the sliding bracket, a driving shaft is rotatably provided on one side of the sliding groove, and a driven shaft is rotatably provided on the other side, a rotating belt is sleeved between the driving shaft and the driven shaft, a linkage block is fixedly provided on the rotating belt, and the linkage blocks are evenly distributed on the rotating belt, a sliding block is fixedly provided at the bottom of the extension bracket, a linkage groove matching the linkage block is provided at the bottom of the sliding block, a sliding motor is fixedly provided on one side of the sliding bracket, and the output end of the sliding motor is fixedly connected to the driving shaft.

[0014] By adopting the above-mentioned technical solution, considering that the distance required for the forward and backward movement of the mirror in the prior art is limited, in order to increase the distance of the movement of the mirror, the extension bracket is additionally extended on the sliding bracket in the present application. Specifically, the sliding motor drives the driving shaft to rotate, thereby driving the rotating belt to rotate, and the linkage block on the rotating belt drives the sliding block under the extension bracket to move, thereby realizing the forward and backward movement of the extension bracket on the sliding bracket.

[0015] Furthermore, an L-shaped rod is rotatably connected to one end of the sliding bracket away from the rotating bracket, and a connecting block is fixedly provided on the same side of the extending bracket. A connecting hole is provided on the connecting block to be plugged into the L-shaped rod, and a damper fixedly connected to the connecting block is provided in the connecting hole.

[0016] By adopting the above technical solution, considering that the extension bracket is not required under all circumstances, a structure for limiting the extension bracket on the sliding bracket is provided in the present application. Specifically, the L-shaped rod connected to the sliding bracket is rotated and inserted into the connecting hole on the connecting block. The L-shaped rod is left on the connecting block through the damping setting, so that the extension bracket stays on the sliding bracket. Although the extension bracket can be prevented from moving forward and backward by simply not starting the sliding motor, in actual use, when the L-shaped rod is not set, slight shaking will occur, resulting in defects in the mirror movement effect.

[0017] Furthermore, an unlocking device is provided on one end of the bottom of the rotating frame close to the L-shaped rod, and the unlocking device includes an unlocking block fixedly connected to the rotating frame, an unlocking groove is provided at the bottom of the unlocking block, an unlocking spring is fixedly provided in the unlocking groove, an unlocking rod is inserted in the unlocking groove, and the unlocking rod is fixedly connected to the unlocking spring.

[0018] By adopting the above technical solution, when the length brought by the extended bracket is needed, it is only necessary to start the rotating motor to move the rotating frame. When the rotating frame moves to the end, the unlocking rod will move downward to the connecting hole on the connecting block due to the elastic force of the unlocking spring, allowing the L-shaped rod to detach from the connecting block, thereby unlocking the extended bracket.

[0019] Furthermore, the bottom of the unlocking lever is cone-shaped.

[0020] By adopting the above technical solution, it is prevented that the unlocking rod is stuck and the rotating frame is recovered after the extension bracket is unlocked.

[0021] Furthermore, a connecting frame is fixedly provided on the upper end of the rotating frame, connecting shafts are fixedly provided at both ends of the camera, the connecting shafts are rotatably connected to the connecting frame, micro motors are fixedly provided on both sides of the connecting frame, and the output ends of the micro motors are fixedly connected to the connecting shafts.

[0022] By adopting the above technical solution, the movement of the upper and lower lenses can be achieved by rotating and connecting the two ends of the camera to the connecting frame.

[0023] Furthermore, a video capture card is applicable to a video capture conversion device for live camera movement described in any one of the above technical solutions, including a capture card, the capture card is installed in a camera, and a placement port for installing the capture card is opened on the camera.

[0024] By adopting the above technical solution and installing the acquisition card directly on the camera, it is possible to avoid disconnection caused by jitter during wired connection.

[0025] In summary, the present application includes the following beneficial technical effects: through precise mechanical structure design, the device can realize multi-dimensional movement of the camera during live broadcast, including left and right rotation and forward and backward movement. This flexible camera movement method can capture more angles and dynamic images, making the live broadcast content richer and more vivid, thereby significantly improving the overall quality of the live broadcast image. The device brings a more realistic viewing experience to the audience by simulating the movement trajectory of the camera in the real world, such as smooth rotation and smooth translation. This immersive experience can attract the audience's attention, make them more involved in the live broadcast content, and improve the interactivity and viewing experience of the live broadcast. The design of the equipment allows the operator to make instant lens adjustments as needed during the live broadcast, such as quickly switching perspectives or tracking specific objects. This flexibility not only helps to improve the professionalism of the live broadcast, but also better meet the audience's demand for diversified live content. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present application is further described in detail below with reference to the accompanying drawings.

[0034] Example, see Figure 1 A video acquisition and conversion device for camera live broadcast movement includes a camera 6 and an adjustment bracket. The adjustment bracket consists of two major parts: a base bracket 1 and a rotating bracket 11. The base bracket 1 firmly supports the entire device to ensure that it remains stable during use. The rotating bracket 11 is rotatably connected to the base bracket 1 in an ingenious way, providing flexible support for the movement of the camera 6.

[0035] A sliding bracket 3 is fixedly arranged on the rotating bracket 11, and the function of the sliding bracket 3 is to push the camera 6 to move forward and backward. The sliding bracket 3 can ensure the stability and accuracy of the camera 6 during the movement. At the same time, a rotating component is also arranged on the base bracket 1, and the rotating component can drive the rotating bracket 11 to rotate left and right to realize left and right camera movement.

[0036] In actual operation, the camera 6 can easily move left and right as the rotating bracket 11 rotates. This rotational movement brings rich perspective changes to the live broadcast picture. And through the push of the sliding bracket 3, the camera 6 can move forward and backward, further expanding the dynamic range of the live broadcast picture. This combination of left and right rotation and forward and backward movement makes the live broadcast picture more vivid and interesting, and can bring a more immersive viewing experience to the audience.

[0037] In this embodiment, refer to Figure 2 as well as Figure 3 A base platform 2 is fixedly arranged on the base bracket 1, and the rotating assembly includes a forward and reverse motor 21 fixedly connected to the base platform 2, and a forward and reverse gear 22 is fixedly arranged on the output end of the forward and reverse motor 21. A circle of placement grooves is opened on the rotating bracket 11, and a driven gear 23 is fixedly arranged in the placement groove. The forward and reverse gear 22 is meshed with the driven gear 23.

[0038] When the mirror is moved left and right, the forward and reverse gears 22 on the motor are driven to rotate by the forward and reverse motor 21, thereby driving the meshed driven gears 23 on the rotating bracket 11, thereby driving the rotating bracket 11 to rotate clockwise or counterclockwise, and the rotating bracket 11 is driven by the forward and reverse motor 21 to rotate left and right.

[0039] In this embodiment, refer to Figure 4 , Figure 5 as well as Figure 6 An extension bracket 4 is installed on the sliding bracket 3, a rotating bracket 5 is installed at the bottom of the camera 6, a rotating motor 51 is fixedly arranged at the bottom of the rotating bracket 5, a rotating gear 23 is fixedly connected on the output end of the rotating motor, a gear bar 41 is fixedly arranged on the extension bracket 4, the gear bar 41 is meshed with the rotating gear 23, a sliding rod 43 is fixedly arranged on one side of the rotating bracket 5, and a long groove 44 matching the sliding rod 43 is provided on the extension bracket.

[0040] When it is necessary to move the camera forward and backward, the rotating motor 51 is started, the output end connection is rotated, the rotating gear 23 is rotated, and then meshes with the gear rack 41, driving the bottom of the rotating frame 5 to move in the slide groove on the extension bracket 4. The rotating motor 51 in the present application adopts a motor that can rotate forward and reverse, so as to facilitate the camera 6 on the rotating frame 5 to move forward and backward.

[0041] In this embodiment, limiting plates fixedly connected to the extension bracket 4 are arranged on both sides of the long groove 44 .

[0042] The limiting plates on both sides of the long groove 44 are used to limit the separation of the rotating frame 5, so as to avoid affecting the movement of the camera 6.

[0043] In this embodiment, a sliding groove is provided on the sliding bracket 3, a driving shaft 32 is rotatably provided on one side of the sliding groove, and a driven shaft 33 is rotatably provided on the other side, a rotating belt 34 is sleeved between the driving shaft 32 and the driven shaft 33, a linkage block 36 is fixedly provided on the rotating belt 34, and the linkage blocks 36 are evenly distributed on the rotating belt 34, a sliding block 39 is fixedly provided at the bottom of the extension bracket 4, and a linkage groove 40 matching the linkage block 36 is provided at the bottom of the sliding block 39, a sliding motor 31 is fixedly provided on one side of the sliding bracket 3, and the output end of the sliding motor 31 is fixedly connected to the driving shaft 32.

[0044] Taking into account that the distance required for the forward and backward movement of the mirror in the prior art is limited, in order to increase the distance of the movement of the mirror, the present application further extends the extension bracket 4 on the sliding bracket 3. Specifically, the sliding motor 31 drives the active shaft 32 to rotate, thereby driving the rotating belt 34 to rotate, and the linkage block 36 on the rotating belt 34 drives the sliding block 39 under the extension bracket 4 to move, thereby realizing the forward and backward movement of the extension bracket 4 on the sliding bracket 3.

[0045] In this embodiment, an L-shaped rod 37 is rotatably connected to the end of the sliding bracket 3 away from the rotating bracket 11, and a connecting block 42 is fixedly provided on the same side of the extending bracket 4. A connecting hole is provided on the connecting block 42 to be plugged into the L-shaped rod 37, and a damper fixedly connected to the connecting block 42 is provided in the connecting hole.

[0046] Considering that the extension bracket 4 is not required in all cases, a structure is provided in the present application to limit the extension bracket 4 on the sliding bracket 3. Specifically, the L-shaped rod 37 connected to the sliding bracket 3 is rotated and inserted into the connecting hole on the connecting block 42. The L-shaped rod 37 is retained on the connecting block 42 through the damping setting, so that the extension bracket 4 stays on the sliding bracket 3. Although the extension bracket 4 can be prevented from moving forward and backward by simply not starting the sliding motor 31, in actual use, when the L-shaped rod 37 is not set, slight shaking will occur, resulting in defects in the mirror movement effect.

[0047] In this embodiment, an unlocking device is provided on one end of the bottom of the rotating frame 5 close to the L-shaped rod 37, and the unlocking device includes an unlocking block 62 fixedly connected to the rotating frame 5, an unlocking groove is provided at the bottom of the unlocking block 62, an unlocking spring 64 is fixedly provided in the unlocking groove, an unlocking sleeve fixedly connected to the unlocking block 62 is provided in the middle of the unlocking spring 64, an unlocking rod 63 is inserted in the unlocking sleeve, and a rod body of the unlocking rod 63 is fixedly provided with a ring, and the ring is fixedly connected to the unlocking spring 64.

[0048] When the length brought by the extension bracket 4 is needed, it is only necessary to start the rotating motor 51 to move the rotating bracket 5. When the rotating bracket 5 moves to the end, the unlocking rod 63 will move downward to the connecting hole on the connecting block 42 due to the elastic force of the unlocking spring 64, so that the L-shaped rod 37 is separated from the connecting block 42, thereby unlocking the extension bracket 4.

[0049] In this embodiment, the bottom of the unlocking rod 63 is cone-shaped to prevent the unlocking rod 63 from getting stuck on the rotating frame 5 and being recovered after the extension bracket 4 is unlocked.

[0050] In this embodiment, a connecting frame 54 is fixedly provided on the upper end of the rotating frame 5, and connecting shafts 55 are fixedly provided at both ends of the camera 6. The connecting shafts are rotatably connected to the connecting frame 54. Micro motors are fixedly provided on both sides of the connecting frame 54, and the output ends of the micro motors are fixedly connected to the connecting shafts 55. By rotatably connecting both ends of the camera 6 to the connecting frame 54, the movement of the upper and lower lenses can be realized.

[0051] In this embodiment, a video capture card is applicable to any one of the above technical solutions. A video capture conversion device for camera live broadcast includes a capture card. A placement port for installing the capture card 61 is opened on the camera 6. The capture card 61 is installed in the camera 6. By installing the capture card on the camera 6, jitter during wired connection can be avoided to cause disconnection.

[0052] Specific implementation process: The video acquisition conversion device for camera live broadcast movement integrates a camera 6, an adjustment bracket and advanced video acquisition technology, providing users with a highly flexible and efficient live broadcast movement solution. The main components of the device include a camera 6, an adjustment bracket for mounting the camera 6 and a video acquisition card 61.

[0053] The design of the adjustment bracket fully considers the needs of live broadcast camera movement, including a base bracket 1 and a rotating bracket 11 rotatably connected to the base bracket 1, and a sliding bracket 3 for pushing the camera 6 is fixedly set on the rotating bracket 11. This design allows the camera 6 to rotate left and right with the rotating bracket 11 to achieve left and right camera movement; at the same time, through the cooperation of the extension bracket 4 and the rotating motor 51 on the sliding bracket 3, the camera 6 can also move forward and backward to meet the needs of forward and backward camera movement. The forward and reverse motor 21 on the base bracket 1 accurately drives the rotating bracket 11 to rotate clockwise or counterclockwise through meshing transmission, further improving the flexibility and accuracy of camera movement.

[0054] In order to increase the distance and range of the camera movement, the device is also designed with an extension bracket 4. A sliding groove and a rotating belt 34 are provided on the sliding bracket 3, a linkage block 36 is fixed on the rotating belt 34, and a sliding block 39 matching the linkage block 36 is fixed on the bottom of the extension bracket 4. When the sliding motor 31 drives the driving shaft 32 to rotate, the rotating belt 34 and the linkage block 36 will move accordingly, thereby driving the extension bracket 4 to move forward and backward on the sliding bracket 3, thereby greatly expanding the range and distance of the camera movement.

[0055] In addition, the device is also cleverly provided with a limiting and unlocking device of the L-shaped rod 37. The end of the sliding bracket 3 away from the rotating bracket 11 is rotatably connected to the L-shaped rod 37, and a connecting block 42 is fixed on the extension bracket 4. The L-shaped rod 37 can be inserted into the connecting hole on the connecting block 42 and is retained on the connecting block 42 by the damping setting, thereby limiting the movement of the extension bracket 4. When the extension bracket 4 needs to be used, it is only necessary to start the rotating motor 51 to move the rotating bracket 5, and the unlocking rod 63 will move downward due to the elastic force of the unlocking spring 64, so that the L-shaped rod 37 is separated from the connecting block 42, thereby unlocking the extension bracket 4.

[0056] The camera 6 is rotatably connected to the connecting frame 54 at both ends, and micro motors are arranged on both sides of the connecting frame 54. Driven by the micro motor, the camera 6 can move the upper and lower lenses to achieve multi-angle shooting, further enriching the expressiveness and creative space of the live broadcast camera movement.

[0057] The video capture card 61 provided with the device also has excellent performance. The video capture card 61 is directly mounted on the camera 6, avoiding the connectivity problem during wired connection and effectively preventing disconnection caused by jitter.

[0058] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
