By capturing objects from all angles and synthesizing them into 3D models, the details of objects can be presented in an intuitive and three-dimensional way, greatly enhancing information display and interactive experience. For example, in cultural heritage protection, 3D models can completely record the structure and texture of ancient buildings, preventing the loss of cultural relic information due to time or natural factors; in the e-commerce field, consumers can view product details through 3D models from 360 degrees, enhancing the shopping experience. As the basic equipment for real-scene 3D modeling, the performance of the capturing device directly affects the efficiency and quality of modeling.

[0003] However, existing real-scene 3D shooting devices have significant drawbacks. Traditional shooting methods often rely on manual rotation of the object being photographed to obtain images from different angles. This method is not only inefficient, but also makes it difficult to ensure the consistency and accuracy of the rotation angle each time, easily leading to problems such as incomplete coverage of shooting angles or repeated shooting.

[0025] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described below.

[0026] To address the problems existing in the background technology, this application proposes the following technical solution: a real-scene 3D shooting device, comprising: a base 3, a blocking component, and a shooting component. A turntable 7 is rotatably connected to the base 3, and a driving part for driving the turntable 7 to rotate is provided below the base 3. The driving part is used to drive the turntable 7 to rotate intermittently. The blocking component is detachably mounted on the base 3, and a supplementary light 6 is detachably connected to the blocking component. The shooting component is located on the outside of the base 3 and is used to shoot objects on the turntable 7. Support legs are fixedly connected to the bottom of the base 3. The shooting component includes a tripod 1 and a camera 2 detachably connected to the top of the tripod 1. The base 3, as the basic support structure of the entire shooting device, is made of high-strength engineering plastic or metal to ensure stability when carrying objects and rotating the turntable 7. The support legs around the bottom are treated with anti-slip material to adapt to different shooting locations and prevent the device from sliding or tilting during use. The turntable 7 rotatably connected to the base 3 is supported by high-precision bearings, which rotate smoothly and stably, and can bear objects of different weights and ensure their stable rotation. The drive unit allows the turntable 7 to rotate intermittently at a preset rhythm without manual intervention, greatly improving shooting efficiency.

[0027] The shielding component is detachably mounted on the base 3, effectively isolating ambient light interference and creating stable lighting conditions for shooting. The detachable design of the fill light 6 allows for flexible adjustment of light intensity and angle according to shooting needs, preventing shadows or reflections on the object's surface and ensuring the uniformity and realism of the captured image. The tripod 1 in the shooting assembly is freely adjustable in height and angle to adapt to objects of different sizes and shooting requirements. The detachable connection of the camera 2 facilitates the replacement of different models of equipment, improving the versatility of the device. Through the coordinated work of its components, the entire solution achieves multi-angle, high-precision shooting of objects, providing high-quality image materials for real-world 3D modeling. It solves the problems of unstable lighting and incomplete angle coverage in traditional shooting methods, significantly improving the efficiency and accuracy of 3D modeling.

[0028] In this embodiment, the drive unit includes a motor 9, a gear, and a rack 11. The motor 9 is fixedly connected to the bottom of the base 3. A threaded rod 10 is fixedly connected to the output end of the motor 9. A nut block 12 is threadedly connected to the outside of the threaded rod 10. A limit rod 13 is fixedly connected to the bottom of the base 3, passing through the nut block 12. A rack 11 is fixedly connected to the outside of the nut block 12. A rotating rod 8 is fixedly connected to the bottom of the turntable 7, rotatably connected to the base 3. A gear is fixedly connected to the outside of the rotating rod 8. The drive unit uses the motor 9 as a power source. Through the transmission structure of the threaded rod 10-nut block 12-rack 11-gear, the rotational motion of the motor 9 is converted into the intermittent rotation of the turntable 7. The motor 9 is fixed to the bottom of the base 3 to ensure the stability of the power output. Its speed and rotation cycle can be precisely adjusted by the controller to adapt to different shooting requirements. The threaded engagement between the threaded rod 10 and the nut block 12 realizes the conversion of linear motion. The limit rod 13 passes through the nut block 12 to prevent it from deviating during movement and ensure the accuracy of transmission.

[0029] The meshing transmission between the rack 11 and the gear converts the linear motion of the nut block 12 into the rotational motion of the gear, which in turn drives the rotating rod 8 at the bottom of the turntable 7 and the turntable 7 to rotate. This transmission structure features accurate transmission ratio and smooth operation, enabling intermittent rotation of the turntable 7. When the motor 9 rotates, the threaded rod 10 drives the nut block 12 and the rack 11 to move, and the rack 11 pushes the gear to rotate at a certain angle; when the motor 9 stops, the turntable 7 also stops, providing a stable time window for the camera 2 to capture images. By controlling the intermittent rotation cycle of the motor 9, the angle of each rotation of the turntable 7 can be precisely adjusted, ensuring that every facet of the object can be completely captured by the camera 2, avoiding blind spots in the shooting. This driving method does not require complex programming or mechanical structures, is easy to operate and highly reliable, and effectively solves the problems of inaccurate angle control and low shooting efficiency when manually rotating the turntable 7 in the traditional way, providing automated and high-precision rotation support for 3D modeling and shooting.

[0030] In this embodiment, the shielding assembly includes a shielding cover 4 and a top plate 5 disposed above the shielding cover 4. A snap-fit ​​strip 18 is fixedly connected to the bottom of the shielding cover 4. A limiting frame 20 is fixedly connected to the base 3, and the snap-fit ​​strip 18 snaps into the limiting frame 20. A snap-fit ​​frame 14 is fixedly connected to the bottom of the top plate 5 and snaps into the top of the shielding cover 4. Magnets are fixedly connected to both the limiting frame 20 and the snap-fit ​​frame 14. Iron pieces are fixedly connected to the corresponding positions of the magnets on the outside of the snap-fit ​​strip 18 and the shielding cover 4. The shielding assembly adopts a split design, consisting of the shielding cover 4 and the top plate 5. Quick installation and disassembly are achieved through the snap-fit ​​structure between the snap-fit ​​strip 18 and the limiting frame 20, and between the snap-fit ​​frame 14 and the shielding cover 4. The high precision of the fit between the snap-fit ​​strip 18 and the limiting frame 20 ensures that the shielding cover 4 is securely installed on the base 3, preventing displacement due to vibration during shooting. The top plate 5 covers the top of the shield 4, forming a closed light-blocking space that effectively isolates the ambient light above and ensures uniform lighting in the shooting area.

[0031] The magnetic connection between the magnet and the iron sheet further enhances the stability of the shielding assembly and makes disassembly easier; the snap-fit ​​structure can be separated with just a little force, requiring no additional tools. This design ensures the sealing of the shielding assembly and allows operators to quickly replace or adjust the shield 4 and top plate 5 to adapt to the shooting needs of items of different sizes. For example, when shooting large items, the top plate 5 can be removed to expand the shooting space; when shooting small items, the shield 4 and top plate 5 can be used together to create a cleaner shooting environment. In addition, the magnetic connection reduces wear during installation, extends the service life of the shielding assembly, and avoids the problem of parts being lost due to screw fixing or other methods, improving the practicality and ease of maintenance of the device.

[0032] In this embodiment, both the shield 4 and the top plate 5 are provided with through holes 19. A limiting ring 15 is fixedly connected to the outside of the through hole 19. Magnets 16 are fixedly connected to the area surrounding the through hole 19 on the outside of the shield 4 and the top plate 5. An iron ring 17 is fixedly connected to the outside of the fill light 6. The fill light 6 passes through the through hole 19, and the magnet 16 is attracted to the iron ring 17. The through hole 19 of the shield 4 and the top plate 5 is designed to provide flexible position selection for the installation of the fill light 6. The operator can install the fill light 6 in the through hole 19 of the shield 4 or the top plate 5 according to the shape of the object and the shooting requirements to achieve multi-angle fill light. The limiting ring 15 is fixed to the outside of the through hole 19, which on the one hand provides installation positioning for the fill light 6, ensuring that the axis of the fill light 6 is aligned with the through hole 19, and on the other hand prevents the fill light 6 from shaking during use, ensuring the stability of the fill light effect.

[0033] The magnetic connection between magnet 16 and iron ring 17 makes the installation and removal of the fill light 6 more convenient. Simply align the iron ring 17 of the fill light 6 with the magnet 16 around the through hole 19, and the fill light 6 will be fixed in place by magnetic attraction, without the need for screws or other fasteners, making the operation simple and quick. This design allows operators to adjust the position and angle of the fill light 6 at any time according to shooting needs. For example, when shooting the top of an object, the fill light 6 can be installed in the through hole 19 of the top plate 5; when shooting the side, it can be installed in the through hole 19 of the shield 4, ensuring that the light can evenly cover the surface of the object and avoid shadows or reflections. Furthermore, the magnetic connection has moderate strength, ensuring that the fill light 6 will not fall off during shooting, while allowing for easy removal when adjustments are needed, improving shooting efficiency and flexibility. The detachable design of the fill light 6 also facilitates the replacement of lamps with different power or color temperatures to adapt to the shooting needs of objects with different materials, further improving the quality and accuracy of the 3D modeled images.

[0034] The usage method of this embodiment is as follows:

[0035] First, place the shield 4 on the base 3 and let the snap-fit ​​strip 18 snap into the limiting frame 20 to fix the position of the shield 4. Then place the top plate 5 on top of the shield 4 and let the snap-fit ​​frame 14 snap into the top of the shield 4 to fix the position of the top plate 5.

[0036] Next, place the item to be modeled and photographed on turntable 7, adjust the height and angle of camera 2 using tripod 1, and then start motor 9 to rotate intermittently via controller. Motor 9 drives threaded rod 10 to rotate intermittently, thereby realizing the intermittent sliding of rack 11. Rack 11 drives gear to rotate intermittently, gear drives turntable 7 to rotate intermittently via rotating rod 8, turntable 7 drives the item to rotate intermittently, and during the intervals of intermittent rotation, the item can be photographed by camera 2.

[0037] By controlling the cycle time of the intermittent rotation of motor 9, the angle at which turntable 7 drives the item to rotate intermittently can also be controlled.

[0038] Alternatively, if supplemental lighting is needed, the supplemental light 6 can be inserted into the through hole 19 and fixed by the magnet 16 and the iron ring 17.
