Description

Technical Field

[0001] This utility model relates to the field of image acquisition technology, specifically to a light-shielding and interference-resistant camera acquisition component. Background Technology

[0002] In scenarios such as collecting classroom assignments, document images, document ownership verification, or form entry, cameras are often used to directly capture content on paper or screens. However, due to factors such as ambient stray light, specular reflection, misalignment, paper warping, and cable pulling, the image quality and stability are often unsatisfactory.

[0003] Existing camera mounts typically only have coarse tilt adjustment or single-stage locking, which are insufficient in terms of light blocking, anti-reflection, and precise positioning. Strong sidelight or backlight directly entering the lens will create light spots and fogging on the photos, reducing image contrast and color saturation. Secondly, improper cable restraint can cause angle drift. Therefore, a light-blocking and interference-resistant video acquisition component is needed. Utility Model Content

[0046] Please see Figure 1 - Figure 9 The light-shielding and interference-resistant camera acquisition component includes:

[0047] Base 1 and camera 2 mounted on top of base 1;

[0048] A lifting column 3 is installed on the base 1 to adjust the height of the camera 2;

[0049] An angle adjustment component 4 is installed on the lifting column 3 to adjust the angle of the camera 2;

[0050] A gimbal 5 is fixedly installed on the angle adjustment assembly 4;

[0051] A fixing component 6 is installed on the gimbal 5 to connect the camera 2 to the gimbal 5;

[0052] A rigid light-shielding tube 7 is fitted onto the fixing component 6 for light shading;

[0053] A snap-fit ​​mechanism is provided inside the rigid light-shielding tube 7 to fix the rigid light-shielding tube 7 to the camera 2.

[0054] A polarizer 9 is set at one end of the rigid light-shielding tube 7;

[0055] And a light-shielding skirt 10 threadedly connected to the end of the rigid light-shielding tube 7, and a polarizing plate 9 located between the rigid light-shielding tube 7 and the light-shielding skirt 10.

[0056] The light-shielding and anti-interference camera acquisition component provided by this utility model allows for the following steps: 1) Place the base 1 on a desktop or terminal surface. Then, manually adjust the length of the lifting column 3 as needed to adjust the height and focal length of the camera 2. After adjusting the outer side, the angle of the camera 2 can be adjusted via the angle adjustment component 4 on the lifting column 3 and the gimbal 5 on the angle adjustment component 4, enabling the camera 2 to capture different sides of the object. Finally, the rigid light-shielding tube 7 is fixed to the camera 2 via a snap-fit ​​mechanism. The rigid light-shielding tube 7, polarizer 9, and light-shielding skirt 10 achieve triple light shielding and reflection suppression, significantly reducing stray light or glare.

A scale 16 is fixedly installed on both sides of the fixed cylinder 31.

[0060] Specifically, when the fixed column 32 moves, the fixed column 32 synchronously drives the connecting block 14, and then the connecting block 14 drives the U-shaped frame 15 to move on the fixed cylinder 31. Finally, with the help of the scale 16, the adjusted value of the fixed column 32 can be viewed, which makes it convenient for manual precise adjustment of the focal length of the camera 2.

[0062] Specifically, the toothed disc 42 is manually rotated, and the meshing teeth of the connecting toothed disc and the rotating toothed disc 42 connected to both ends of the fixed column 32 rotate, so that the rotating toothed disc 42 adjusts the angle between the connecting plate 41 and the connecting toothed disc, thereby enabling the camera 2 to select the shooting area.

[0063] Furthermore, the snap-fit ​​mechanism includes an annular groove 1 on the inner wall of the rigid light-shielding tube 7, an annular groove 2 on the outer wall of the base 1, a rubber ring 8 on the inner side of the annular groove 2, and the rubber ring 8 snap-fitting with the annular groove 1.

[0064] Specifically, the rigid light shield 7 is manually fitted onto the front end of the base 1, and the rubber ring 8 in the second annular groove is engaged with the first annular groove on the rigid light shield 7, so that the rigid light shield 7 can be stably fixed on the camera 2, and the back of the rigid light shield 7 can be easily disassembled.

[0065] Furthermore, the fixing component 6 includes a fixing plate 61 fixedly installed on the gimbal 5, a connecting seat 62 fixedly installed on the outer side wall of the camera 2, a second bolt 63 inserted into the hole communicating with the fixing plate 61 and the connecting seat 62, and a nut threadedly connected to the screw end of the second bolt 63.

[0066] Specifically, the second bolt 63 is manually inserted into the hole connecting the fixing plate 61 and the connecting seat 62, and then the nut is screwed onto the second bolt 63, thereby facilitating the installation and disassembly of the camera 2 and the gimbal 5.

[0067] Furthermore, an L-shaped positioning block 19 is fixedly installed on the top of the base 1, a ring target is provided at the inner corner of the L-shaped positioning block 19, and a paper pressing spring 20 is fixedly installed on the horizontal section of the L-shaped positioning block 19.

Both the wire clamps 12 and the base 1 are provided with screw holes, and a first bolt 13 is threaded into the screw holes.

[0071] The technical solution provided in this embodiment is as follows: the cable is moved into the cable tray 11 by manual means, and then the cable clamp 12 is fixed on the base 1 by the first bolt 13 and the screw hole connected to the base 1 and the clamp 12. This can block the cable in the cable tray 11, thereby suppressing the angle drift caused by cable pulling and improving anti-interference and acquisition stability.

[0072] Furthermore, a protective pad 17 is fixedly installed on the bottom of the base 1, and the protective pad 17 is made of rubber.

[0073] Specifically, the protective pad 17 increases the friction between the base 1 and the desktop or terminal surface, thereby improving the stability of the base 1.

[0074] Furthermore, an adhesive paper 18 is provided in the round hole in the middle of the protective pad 17, and the adhesive paper 18 is fixedly installed on the protective pad 17.

[0075] Specifically, when the base 1 is placed on the desktop or terminal surface manually, the adhesive tape 18 can be used to stick the base 1 to the desktop or terminal surface, thereby ensuring the stability of the base 1 and making the device less likely to move during use.

[0076] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
