Description

Technical Field

[0001] This utility model relates to the field of panoramic array camera technology, and specifically to an array camera anti-collision device. Background Technology

[0002] In automated and information-based monitoring of tunnels, using cameras to capture images and then analyzing them using computer technology to identify potential risks is one of the most effective and advanced detection methods available today. An array lens is a lens system composed of multiple small lenses arranged in a specific pattern. Array lenses can acquire images 360°, quickly obtaining 360° panoramic image information from any location within the tunnel, which is very fast and convenient, and significantly reduces the difficulty of image information processing. However, the tunnel environment is complex and variable, with conditions such as small tunnels, numerous obstacles, and lack of effective lighting. When used in tunnels and similar environments, array cameras face a significant risk of collision in all directions, easily damaging the camera lenses. Therefore, it is necessary to develop an array camera structure that can effectively prevent collisions without affecting its use, avoiding damage to the array lenses due to collisions during operation.

[0003] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an array camera anti-collision device. A protective bracket is formed around the lens by a radial bracket and a circumferential bracket to achieve the protective function of the array lens, protecting the camera without affecting its normal operation.

[0005] To achieve the above objectives, this utility model provides an array camera lens anti-collision device, including a circular camera mounting shell and cameras, a plurality of cameras being installed inside the camera mounting shell, each camera including a lens, the lenses being uniformly installed along the outer periphery of the camera mounting shell, the lenses protruding radially along the camera mounting shell, and a protective bracket being fixedly connected to the outer periphery of the camera mounting shell.

[0006] The protective bracket includes radial brackets, which are fixedly connected to both sides of the camera mounting housing and evenly distributed circumferentially. The radial brackets are located between adjacent lenses and protrude radially along the camera mounting housing. The protruding ends of the radial brackets located on the same side of the camera mounting housing are fixedly connected to protective rings to protect the protruding lenses.

[0007] Furthermore, the protective bracket also includes a circumferential bracket, and the number of radial brackets located on either side of the camera mounting housing is the same as the number of lenses. The protruding ends of adjacent radial brackets located on the same side of the camera mounting housing are respectively fixedly connected to the two ends of the circumferential bracket to form the protective ring.

[0008] Furthermore, the protective bracket also includes a connecting rod, and the protruding ends of the two radial brackets between adjacent lenses are respectively fixedly connected to the two ends of the connecting rod.

[0009] Furthermore, the camera mounting housing has fixing screw holes on both sides, and the radial bracket is threadedly connected to the fixing screw holes by bolts.

[0010] Furthermore, the length by which the radial bracket protrudes beyond the outer edge of the camera mounting housing is greater than or equal to the length by which the lens protrudes beyond the outer edge of the camera mounting housing.

[0011] Furthermore, both the camera mounting housing and the protective bracket are made of aluminum alloy.

[0012] Furthermore, a protective cover can be detachably connected to the front end of the lens.

[0013] The above-mentioned solution of this utility model has the following beneficial effects:

[0014] The array camera anti-collision device provided by this utility model sets the camera inside an aluminum alloy camera mounting shell, with the lens protruding along the outer periphery of the mounting shell. Then, radial and circumferential supports are set along the outer periphery of the mounting shell, and a protective support is formed around the protruding lens. This can effectively protect the array camera from physical collisions that may occur during use and shooting, and avoid damage to the lens. Moreover, the lens can move relatively freely within the protective support area without affecting the lens's telescopic adjustment of focus. The protective support forms a relatively open protective area and does not affect the lens's shooting framing.

[0015] Other beneficial effects of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0023] like Figures 1-3 As shown, this utility model provides an array camera lens anti-collision device, including a circular camera mounting housing 1 and cameras. Several cameras are mounted inside the camera mounting housing 1. Each camera includes a lens 3, which is evenly mounted along the outer periphery of the camera mounting housing 1 and protrudes radially from the housing. A protective bracket 2 is fixedly connected to the outer periphery of the camera mounting housing 1. In this embodiment, 12 cameras are preferred; in other embodiments, the number of cameras can be adjusted according to actual shooting needs. The camera body is fixedly installed inside the camera mounting housing 1, effectively sealing and protecting the camera's electronic control components, minimizing the risk of collisions, and preventing contamination from moisture, dust, etc. The camera lens 3 protrudes from the outer periphery of the mounting housing, increasing its range of motion and framing, allowing for convenient adjustment of the lens's focus.

[0024] Specifically, the protective bracket 2 includes a radial bracket 21, a circumferential bracket 22, and a connecting rod 23. The radial brackets 21 are fixedly connected to both sides of the camera mounting housing 1 and are evenly distributed along its circumference. Preferably, both sides of the camera mounting housing 1 are provided with fixing screw holes 11, and the radial brackets 21 are threadedly fixed to the fixing screw holes 11 by bolts, which facilitates the assembly and disassembly of the radial brackets. The radial brackets 21 are respectively located in the middle of adjacent lenses 3 and protrude radially along the camera mounting housing 1. The protruding ends of the radial brackets 21 located on the same side of the camera mounting housing 1 are fixedly connected to protective rings to protect the protruding lenses 3. Further, the number of radial brackets 21 located on any side of the camera mounting housing 1 is the same as the number of lenses 3, that is, there are radial brackets 21 on both sides of the camera mounting housing 1 with the same number of lenses 3. There are two radial brackets 21 in the middle of adjacent lenses 3 and they are located on both sides of the camera mounting housing 1 respectively. The protruding ends of adjacent radial brackets 21 located on the same side of the camera mounting housing 1 are fixedly connected to the two ends of the circumferential brackets 22 to form protective rings. This means that each lens 3 has four radially protruding brackets 21 around its perimeter. The protruding ends of the radial brackets 21 are fixedly connected to circumferential brackets 22, which are preferably arc-shaped. The circumferential brackets 22 form a protective ring, effectively protecting the lens 3 from impacts from different directions through the radial brackets 21 and circumferential brackets 22. Furthermore, the protruding ends of the two radial brackets 21 between adjacent lenses 3 are also fixedly connected to the two ends of a connecting rod 23. The connecting rod 23 connects the radial brackets 21 and circumferential brackets 22 located on both sides of the camera mounting housing 1 into a single unit, improving the stability and effectiveness of the protection. Specifically, both the camera mounting housing 1 and the protective bracket 2 are made of aluminum alloy, ensuring strong protection for the camera and its lens 3 while minimizing the overall weight of the device.

[0025] Furthermore, the radial bracket 21 protrudes beyond the outer edge of the camera mounting housing 1 by a length greater than or equal to the length of the lens 3 protruding beyond the outer edge of the camera mounting housing 1. This ensures that the lens 3 remains within the protective area formed by the protective bracket 2 during the extension and retraction of the focal length, achieving all-round, all-time protection. The front end of the lens 3 is detachably connected to the protective cover 4. Before the equipment enters the tunnel for shooting operations, the protective cover 4 is fitted onto the lens 3 of the array camera to achieve moisture protection and protection. When the equipment enters the tunnel for operations, the protective cover 4 can be removed, and the lens 3 can then take pictures normally.

[0026] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
