Description

Technical Field

[0001] This invention relates to the field of 3D imaging equipment technology, specifically a lightweight and precise rotating bracket adapted to a super-field-of-view 3D stereo dual-camera technology system. It is particularly suitable for professional cameras that support 8K or higher shooting specifications (such as the Nikon Z9), and is used to achieve precise adjustment of the baseline and angle of a single camera in the super-field-of-view dual-camera unit. This meets the hardware adaptation requirements of super 3D shooting for stereo parallax enhancement and distortion-free imaging, and can be widely used in high-end 3D shooting fields such as film and television production, VR content creation, metaverse, and game scene construction. Background Technology

[0002] In the field of 3D imaging, especially in highly immersive film, VR, and metaverse content production scenarios, the ultra-wide field-of-view 3D stereoscopic dual-camera technology system (such as the solution disclosed in the patent with authorization announcement number CN120499357 B) has become a core technology for breaking through the limitations of traditional 3D shooting. Through a baseline shift of 12-30cm, an angle rotation of 1-3°, and a forced parameter configuration of a fixed-focus lens of at least 50mm, it achieves a 2-3 times improvement in stereoscopic depth and a dizzying imaging effect, completely solving the pain points of insufficient stereoscopic depth and image distortion in traditional 3D dual-camera systems. This technology places extremely high demands on the compatibility, lightweight design, adjustment precision, and multi-scene adaptability of shooting equipment. It needs to be compatible with the full range of professional cameras from Nikon, Sony, and Canon. Among them, the Nikon Z9 (supporting 8K 60fps resolution and 12-bit color depth) is the preferred compatible model due to its cinematic image quality. However, existing shooting brackets adapted to this ultra-wide field-of-view 3D technology have significant defects and are difficult to meet professional shooting needs. 1. Insufficient lightweight design: Traditional 3D shooting brackets are mostly general-purpose and heavy structures. They need to be compatible with multiple camera models but have not been optimized for lightweight design. They have a lot of redundant holes and reinforcement parts, which makes the overall weight of the two cameras + bracket + lens generally exceed 10kg, and some professional equipment even exceeds 20kg. Even the main body of the products that are claimed to be "lightweight" weighs about 8kg. This not only increases the difficulty of carrying and setting up, but also limits the application of flexible scenarios such as handheld shooting and shooting in confined spaces.

[0003] 2. Lack of precise adjustment: The angle adjustment mechanism of existing brackets is mostly designed for 360° full stroke, which is not adapted to the 12-30cm baseline displacement and 1-3° angle precise rotation required by the beyond-view 3D technology. In addition, it lacks visual scale markings and cannot meet the fine parameter requirements of no more than 1° for near view, no more than 2° for mid view, and no more than 3° for far view. Although some products support angle adjustment, the range is too wide (-1°-10°), which can easily lead to stereo parallax deviation and affect the image quality.

[0004] 3. Prominent contradiction in compatibility: Existing brackets suffer from the problem of "incompatibility and stability being mutually exclusive"—if a universal quick-release structure is adopted, although it is intended to be compatible with multiple camera brands, the gap between the original holes of different models such as Nikon, Sony, and Canon is large, and the camera body is prone to slippage and displacement when rotating and adjusting; if welding reinforcement or a single brand-specific design is used to improve the fit, universality will be lost and the weight will be further increased, making it impossible to meet the needs of multi-brand compatibility with the requirements of lightweight and stability.

[0005] 4. Insufficient compatibility with high-spec equipment: The image quality parameters of high-end cameras such as the Nikon Z9, such as 8K 60fps and 12-bit color depth, fully meet the requirements of cinematic shooting. However, existing brackets do not fully consider the body size, hole layout, and shooting load characteristics of such high-spec equipment. At the same time, they lack universal compatibility design with other professional cameras from brands such as Sony and Canon. As a result, the advantages of high-spec image quality cannot be fully utilized through the stability and precise adjustment of the bracket, which restricts the full implementation of the super-field-of-view 3D technology.

[0006] 5. Weak compatibility across multiple scenarios: The interface design of existing brackets lacks industry universality, with some only compatible with specific brands of tripods or jib arms, unable to be compatible with mainstream lightweight handheld stabilizers, and lacking dedicated level calibration components, making it difficult to ensure the consistency of dual-camera parallax under different shooting scenarios, further limiting its application scope.

[0007] 6. Functional Expansion and Adaptation: This bracket has the potential to be adapted to real-time viewing systems, and can achieve efficient visualization feedback of shooting parameters through existing structures, adapting to the iterative needs of professional shooting.

[0008] Therefore, there is an urgent need for a shooting bracket specifically designed for ultra-wide field of view 3D stereo dual-camera technology, compatible with the full range of professional cameras from Nikon, Sony, and Canon (Nikon Z9 is preferred). Through a customized universal structural design, it can achieve extreme lightweighting while precisely meeting the requirements of 12-30cm baseline displacement and 1-3° angle adjustment. It also takes into account multi-device compatibility, stability, and ease of operation, and reserves space for real-time viewing system access. This solves the technical pain points of existing brackets and provides reliable hardware support for high-quality shooting of ultra-wide field of view 3D images and future functional expansion. Summary of the Invention

[0011] 3.

[0012] 4. Full-scene compatibility: With a 1 / 4-inch industry-standard interface, it can be directly connected to tripod gimbals without additional adapters. It is also compatible with jib arms, lightweight handheld stabilizers and other equipment, expanding the application boundaries of the entire professional film and television production process.

[0013] 5. Image quality assurance: It integrates horizontal and vertical dual horizontal calibration components and achieves integrated fixation through a dedicated installation structure, ensuring the horizontal and vertical consistency of the dual-camera parallax in real time and avoiding image distortion.

[0015] 7. Flexible expansion: It has the potential to view system adaptation in real time and meet the iterative needs of professional shooting for efficient parameter feedback. Technical solution

[0016] The shooting bracket of this invention includes a main support module, a dual-camera fixing module, a left-camera precision rotation module, a multi-scene adaptation interface module, and a level calibration module. These modules work together to achieve lightweight, precise, stable, and multi-scene compatible shooting. 1. Main Support Module - Pole Structure: The main support consists of two lightweight, high-strength poles (selected from aluminum alloy, carbon fiber, titanium alloy, and magnesium alloy, with aluminum alloy / carbon fiber being preferred). The pole length can be selected from 30-80cm (e.g., ...). Figure 2 1) The diameter range can be selected from 1-3cm (e.g.) Figure 2 2) The thickness is precisely matched with the interfaces of each module; the surface of the rod is marked with a baseline distance scale of 12-30cm (minimum accuracy 1cm), and the side of the adjustable fastener is marked with a scale alignment line, so that the baseline distance can be precisely adjusted by scale alignment; - Fixed buckles: The main support module is equipped with multiple fixed buckles (such as...) Figure 3The system primarily uses poles installed at both ends to reinforce the distance between the two poles. If the pole length exceeds 50cm, a buckle can be added next to the right camera unit to further ensure the stability of the distance. The specific shape of the buckle is not limited (e.g., ...). Figure 7 (3) As long as the spacing can be fixed, it is acceptable.

[0017] 2. Dual-camera fixing module - Fixing substrate: Contains two lightweight, high-strength materials molded in one piece (such as...) Figure 1 The structure is customized to the contours of the target camera body, with a single piece weighing no more than 0.15 kg, and features a double-tube sliding fixing hole (such as...).

Figure 1 (7, 8) Fix the camera position, compatible with the original mounting holes of multiple brands of cameras, and can be paired with a real-time viewing system to achieve parameter visualization feedback; - Assembly status: The assembly relationship between the two fixed base plates and the main support module (e.g.) Figure 6 As shown in the image, the installation layout and modular assembly structure of the dual substrates on the dual rods are clearly illustrated; the bottom of the fixed substrate corresponding to the left camera unit has a pre-machined angle adjustment groove (such as...). Figure 4 (3) The size of the groove matches the adapter rod of the left camera precision rotation module.

[0018] 3. Left-facing camera precision rotation module - Linkage components: Includes a 1-3° dual-lever linkage angle adjustment component (such as...) Figure 4 The upper layer is a fixed scale plate with 1-3° graduations (such as...). Figure 4 Middle 2), middle layer integrated angle pointer (such as Figure 4 4) and positioning rod (such as Figure 4 5); the range of motion of the positioning rod is determined by the pre-made groove on the fixed base plate (e.g., Figure 5 The middle layer (2) is limited to an angle adjustment range of 1-3°; the lower layer is a manual rotating disc (such as...). Figure 4 (1) - Locking structure: A double locking gear assembly achieves dual locking of the adjusted angle and the rotating disk. This assembly is connected to the hole on the back of the fixing base plate (e.g., Figure 5 1) Precise adaptation to achieve an interference-free structure of "fixed machine on the front and adjustable parts on the back".

[0019] 4. Multi-scenario adaptation interface module - Core compatibility: The bottom of the right camera mounting base has a 1 / 4-inch industry-standard screw hole, which can be directly connected to a tripod head that conforms to the interface specification without the need for additional adapters, achieving quick installation and rigid connection; - Expandable compatibility: The main support module has standard connection holes with protective washers at both ends, and a 1 / 4-inch universal screw hole is reserved at the bottom, which can be directly connected to equipment such as jib arms and lightweight handheld stabilizers; if other interface specifications need to be adapted, they can be flexibly expanded through adapters to cover all shooting scenarios.

[0020] 5. Horizontal calibration module - Calibration structure: A horizontal level mounting position is provided in the gap between the two frames, and a dedicated mounting groove for a vertical level is provided on the left edge of the left camera fixing base plate; - Component installation: Two or more miniature bubble levels are embedded in their corresponding positions and fixed with high-strength AB glue, forming an integrated structure flush with the bracket surface without obstructing the camera mounting screw holes; - Calibration accuracy: The horizontal level monitors the horizontal state of the dual-camera baseline in the parallel direction, and the vertical level monitors the vertical state. The calibration error does not exceed 0.5°.

[0021] 6. Parameter Coordination and Adaptation - The bracket is compatible with professional cameras from multiple brands and fixed-focus lenses of at least 50mm; the baseline distance and rotation angle of the dual cameras are coordinated to match the parameters of the ultra-wide field of view 3D stereo dual-camera technology system.

[0037] The core of this invention is to achieve precise adjustment of ultra-wide-field 3D dual cameras through a simplified structure of "moving camera," abandoning the complex dual telescopic track design and balancing structural simplicity and stability. The specific implementation method is described in detail below with reference to the accompanying drawings and the optimized technical solution: I.

Figure 2 The middle 2 (preferably 1.5cm) is precisely matched with the interface of each module; the surface of the rod is marked with a baseline distance of 12-30cm (preferably with a minimum accuracy of 1cm); - Multiple adjustable locking clips (such as Figure 3 The inner diameter of the buckle is compatible with the diameter of the rod, and a scale alignment mark is provided on the side. The buckle is mainly installed at both ends of the rod, and its core function is to stabilize the distance between the two rods. If the length of the rod exceeds 50cm, a buckle can be added next to the right camera unit to further ensure the stability of the distance. The specific shape of the buckle is not limited, as long as it can achieve the above-mentioned functions of fixing the distance and aligning the scale, it can be used (e.g., Figure 7 (3, 4)

[0038] 2. Dual-camera fixed module: - Two customized, lightweight, high-strength integrally molded mounting base plates (such as...) Figure 1 The substrate size is adapted to the target camera body contour and main support module rod specifications (preferably, the weight of a single piece does not exceed 0.15kg), and it is equipped with double-tube fixing holes that precisely match the main support module rod (the hole diameter is adapted to the rod diameter), compatible with the native (e.g., 1 / 4 inch) fixing holes of multiple brands of cameras (e.g., ...). Figure 1 (1, 2) The camera position can be fixed by turning the knob on the base plate (e.g.) Figure 1 (3, 4); the left camera unit has a pre-machined angle adjustment groove at the bottom of the fixed substrate (e.g., ... Figure 4 (3) The size of the groove matches the adapter rod of the left camera precision rotation module.

[0039] 3. Left-facing camera precision rotation module: - 1 set of dual-lever linkage angle adjustment components (such as...) Figure 4 ): The upper layer has a fixed scale plate with 1-3° graduations (such as...) Figure 4 2), using camera fixing screws (such as...) Figure 4 7) The middle layer is fixed together with the camera; the middle layer is equipped with an angle pointer (e.g., ...). Figure 4 4) + Angle positioning rod (e.g.) Figure 4 (5) The range of motion of the positioning rod is determined by the pre-made groove on the fixed base plate (e.g., Figure 5 (2) Limited; the lower layer is equipped with a manual rotating disc (such as...) Figure 4 1) and adapter rod (such as Figure 4 (6) The component includes one set of double locking gear assembly.

[0040] 4. Horizontal calibration module: - Two or more miniature bubble levels (calibration error ≤ 0.5°), with a size-adapted pre-installed mounting location (e.g.) Figure 7 (1, 2).

[0041] II. Bracket Assembly Process 1. Assembly of main support modules (e.g.) Figure 2 , Figure 3 ) Place two lightweight, high-strength poles parallel to each other, aligning them with the markings on the poles' baselines and the buckles. Adjust the distance between the poles to the target range (12-30cm). Depending on the pole length, insert one retaining clip at each end and the middle (e.g., [missing information]). Figure 3 After aligning the scale, tighten the set screw to lock the gap, ensuring that the two rods are parallel and without offset, and that the structure is stable.

[0042] 2. Installation of the dual-camera fixing module and the horizontal calibration module (e.g.) Figure 1 , Figure 6 , Figure 7 ) Two fixed substrates (such as...) Figure 1 The two rods are connected, and the spacing between the base plates is adjusted by the scale on the rods. They are then locked in place by a fixing buckle, forming a structure like... Figure 6 The modular assembly configuration is shown; a shallow groove (sized to fit the vertical level) is pre-machined on the left edge of the left camera mounting base plate, arranged vertically along the dual camera baseline; simultaneously, a horizontal level mounting position is reserved in the gap between the two frames, and a miniature bubble level is embedded in the corresponding position (e.g., Figure 7 (1, 2) Use high-strength adhesive to bond and fix the level to the surface of the bracket, ensuring that the level is flush with the surface of the bracket, without looseness, and without obstructing the camera mounting screw holes and the double tube fixing structure.

[0043] 3. Assembly of the left-side camera precision rotation module (e.g.) Figure 4 , Figure 5 ) (such as) Figure 4 The upper fixed scale plate and the left camera fixed base plate are fixed together through the screw holes on the right side of the plate (e.g., Figure 4 (7) Ensure no relative displacement; the top of the middle positioning rod is inserted into the positioning hole on the camera body (preferably Nikon Z9) to achieve a rigid connection with the camera, and the angle pointer is fixed to the positioning rod to ensure synchronous movement; the top of the adapter rod of the lower manual dial is precisely inserted as... Figure 5 The independent adapter hole marked 1 (this hole is spatially separated from the camera fixing screw hole to avoid adjustment interference); the positioning rod and the rotating disk are connected by a double locking gear assembly to complete the locking structure assembly after adjustment.

[0044] 4. Assembly of supporting equipment and multi-scenario interfaces Two cameras are respectively attached and fixed to two base plates using universal screws (preferably 1 / 4-inch size), ensuring a tight fit between the camera and the base plate adapter surface without gaps. The required lens is installed on the camera to complete the dual-camera unit configuration. The bottom of the right camera mounting base plate has universal screw holes (preferably 1 / 4-inch size), which can be directly connected to tripod heads that meet the corresponding interface specifications, or adapted to other interface specifications through an adapter. Protective washers are installed at the rocker arm connection holes at both ends of the main support module. Through the universal screw holes on the base plate and the rocker arm connection holes, flexible adaptation with various devices such as tripods, rocker arms, and handheld stabilizers can be achieved.

[0045] III. Multi-Scene Shooting Operation Process 1. Tripod Fixing for Shooting: Connect the right camera base plate directly to the tripod head using the universal screw holes, and use the rigidity of the main support rod to ensure a stable connection; observe the horizontal and vertical bubble levels, and fine-tune the tripod height and the angle of the gimbal to center the bubble; adjust the baseline spacing between the two cameras and the rotation angle of the left camera according to the shooting scene requirements and lock them, then start the camera to shoot according to the requirements of the Super-View 3D technology.

[0046] 2. Dynamic Shooting with a Crane: Connect the crane connection holes at both ends of the main support module to the film and television crane and fix it to fit the crane installation space; after adjusting the crane angle, calibrate the level of the dual-camera unit with a level; adjust the baseline spacing of the dual cameras and the rotation angle of the left camera according to the shooting scene requirements and lock them, start the crane to perform dynamic shooting, and ensure that the baseline is stable and without deviation during the shooting process.

[0047] 3. Handheld stabilizer shooting: Connect the main support module directly to the lightweight handheld stabilizer through the universal screw hole; turn on the stabilizer and select the horizontal lock mode, and disable the pan function; the operator holds the main support, adjusts the baseline distance between the two cameras and the rotation angle of the left camera according to the shooting scene requirements, and locks them for flexible follow shooting.

[0048] IV. Verification of Technical Parameters In this embodiment, the weight of the entire bracket is ≤1.5kg, and the total weight after combining two professional cameras (preferably Nikon Z9) and two prime lenses is ≤4.6kg, meeting the requirement of "extreme lightweight within 5kg"; the gap between the main support rod and the double tube fixing hole and the inner diameter of the fixing parts is ≤0.1cm, and there is no looseness or shaking after assembly; the baseline adjustment accuracy is 1cm, the angle adjustment accuracy is 0.1°, and the level calibration error is ≤0.5°, which fully matches the parameters of the ultra-wide field of view 3D stereo dual-camera technology system (patent CN 120499357 B); multi-device adaptation tests show that the bracket is compatible with mainstream cameras such as Nikon, Sony, and Canon, as well as more than 90% of tripods, jibs, and handheld stabilizers with 1 / 4-inch interface specifications, without the need for special adapters; in actual shooting, the stereoscopic layering of 3D images is improved by 2.5 times compared with traditional equipment, with no image distortion or dizziness, meeting the needs of highly immersive content production in cinematic, VR, metaverse, and game scenes.
