[0042] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0043] Reference below Figure 1-Figure 6 An imaging system according to an embodiment of the present application is described.

[0044] Imaging systems can be used in a variety of applications that require precise adjustment of the camera position before leaving the factory, such as video cameras, microscopes, machine vision or visible light television.

[0045] like Figure 1 and Figure 2 As shown, the imaging system of the embodiment of the present application includes: a zoom optical system 2 and an imaging component 1, and the imaging component 1 is used to image the light beam from the zoom optical system 2.

[0046] The imaging assembly 1 includes a camera 11 and a mounting frame 12. The zoom optical system 2 and the camera 11 are arranged in sequence along the optical path. The mounting frame 12 is used to connect with the zoom optical system 2. The mounting frame 12 is provided with a first adjustment portion 121. The camera 11 is provided with a second adjustment portion 1121 that slides with the first adjustment portion 121. The second adjustment portion 1121 can slide relative to the first adjustment portion 121 to make the camera 11 close to or away from the zoom optical system 2.

[0047] The zoom optical system 2 is one of the main parts of the system, which is used to process and adjust the light beam to meet specific imaging requirements. Through the zoom function, the optical system can change the focal length, thereby changing the magnification or viewing angle of the imaging.

[0048] The zoom optical system 2 can receive visible light and near-infrared energy in the 400-950nm spectrum and converge and transmit them to the detector target surface. The zoom optical system 2 can have the functions of zooming, focusing, light bar adjustment and filter switching.

[0049] The zoom optical system 2 can be manually focused, or it can receive a driving voltage from the servo control board 3 to perform a corresponding adjustment action.

[0050] The imaging assembly 1 is used to convert the light beam from the zoom optical system 2 into an image. The camera 11 is the core of the imaging assembly 1, and the camera 11 is used to capture and record the image formed by the light beam; the mounting frame 12 is used to fix and support the camera 11, and is connected to the zoom optical system 2 to improve the relative stability of the camera 11 and the zoom optical system 2.

[0051] The mounting frame 12 is further provided with a first adjusting portion 121 , and the first adjusting portion 121 is used to cooperate with the second adjusting portion 1121 of the camera 11 to achieve position adjustment of the camera 11 .

[0052] The first adjustment portion 121 and the second adjustment portion 1121 slide with each other, so that the camera 11 can move relative to the zoom optical system 2. By adjusting the second adjustment portion 1121 to slide the second adjustment portion 1121 relative to the first adjustment portion 121, the position of the camera 11 can be adjusted continuously and smoothly, so that the user can fine-tune the position of the camera 11 as needed, so that it is closer to or farther away from the zoom optical system 2. This adjustment method provides a flexible adjustment range, and the distance between the camera 11 and the zoom optical system 2 can be changed as needed, thereby optimizing the imaging effect.

[0053] The first adjustment part 121 is located on the mounting frame 12 and can be a slide rail or a slide groove structure, which has a stable support and guiding function. The second adjustment part 1121 is located on the camera 11, and the second adjustment part 1121 is designed with a sliding part that matches the first adjustment part 121, such as a slider or a roller, so that the two can move relative to each other smoothly and accurately. In addition, this design also has high durability and reliability, and can withstand a certain degree of vibration and impact.

[0054] In actual applications, when the position of the camera 11 needs to be adjusted, the user can operate the second adjustment part 1121 manually or through a mechanical device to make the second adjustment part 1121 slide on the first adjustment part 121; at the same time, it can also be combined with an electronic control system to achieve automatic position adjustment and remote control, further improving the flexibility and convenience of the imaging system. The sliding action of the second adjustment part 1121 sliding on the first adjustment part 121 can control the distance between the camera 11 and the zoom optical system 2, thereby achieving fine-tuning of the focal length, viewing angle or working distance. After the adjustment is completed, the camera 11 can be fixedly connected to the mounting bracket 12 by a threaded connector 112 such as a bolt or a fastener such as a buckle to reduce the movement of the camera 11 relative to the mounting bracket 12 during use, thereby reducing the imaging effect.

[0055] According to the imaging system provided in the embodiment of the present application, the mounting frame 12 is provided with a first adjusting portion 121, and the camera 11 is provided with a second adjusting portion 1121 that slidably cooperates with the first adjusting portion 121. The second adjusting portion 1121 is adjusted to slide relative to the first adjusting portion 121 before leaving the factory, so that the position of the camera 11 can be continuously and smoothly adjusted, so that the user can fine-tune the position of the camera 11 as needed to make it closer to or farther away from the zoom optical system 2, so that the distance between the camera 11 and the zoom optical system 2 can be changed as needed, thereby optimizing the imaging effect, while reducing the difficulty of assembling the imaging system and the difficulty of producing parts during the production process, thereby reducing the production cost.

[0056] It should be noted that, in the case of poor imaging quality of the imaging system, the second adjustment portion 1121 can be adjusted to slide relative to the first adjustment portion 121, thereby fine-tuning the distance between the camera 11 and the zoom optical system 2 as needed. This adjustment process can be implemented at any point before and after leaving the factory, with a simple structure and convenient adjustment. Once the camera position is confirmed, the position between the camera 11 and the zoom optical system 2 is fixed and does not need to be moved.

[0057] In some embodiments, Figure 3As shown, the first adjustment portion 121 is a long hole, one end of the long hole is close to the zoom optical system 2, and the other end is far away from the zoom optical system 2; the second adjustment portion 1121 includes a sliding portion at least partially located in the first adjustment portion 121 and a matching portion connected to the sliding portion.

[0058] The first adjustment part 121 is in the shape of a long hole, and this design allows the second adjustment part 1121 to slide linearly inside it. One end of the long hole is close to the zoom optical system 2, and the other end is far away from the zoom optical system 2. This layout provides enough space for the movement of the camera 11, so that it can be close to or away from the optical system.

[0059] The design of the long hole takes into account the relative position relationship between the zoom optical system 2 and the camera 11. By adjusting the position of the second adjustment portion 1121 on the long hole, the distance between the camera 11 and the zoom optical system 2 can be better controlled, thereby adjusting the focus and field of view of the camera 11 imaging.

[0060] The second adjustment portion 1121 includes: a sliding portion and a matching portion. At least part of the sliding portion is located in the first adjustment portion 121, that is, at least part of the sliding portion is located in the long hole. The sliding portion has a size and shape that matches the long hole so that it can slide smoothly in the long hole. Exemplarily, the outer diameter of the sliding portion is less than or equal to the width of the long hole. This design allows the camera 11 to move linearly along the direction of the long hole, and the two ends of the long hole are the end points of the linear movement of the camera 11.

[0061] The matching part plays a connecting and fixing role, and is used to connect the sliding part with the camera 11. In this way, when the sliding part moves in the first adjustment part 121, the matching part can drive the camera 11 to move accordingly, which is convenient to adjust and highly flexible, and helps to achieve higher quality imaging effects.

[0062] The outer contour of the sliding part is contoured with the two ends of the long hole.

[0063] Exemplarily, both ends of the long hole are arc-shaped, the sliding part is a cylindrical shaft, and the outer contour of the sliding part along the axial direction is adapted to the arcs at both ends of the long hole so that the sliding part can move to the end of the long hole, and the arc-shaped setting can reduce stress concentration and improve the reliability of the structure.

[0064] The matching part and the sliding part include at least the following two structures:

[0065] First, the mating part is a blind hole, and one end of the sliding part is detachably connected to the mating part.

[0066] In this embodiment, the matching part is a hole with one end closed, the sliding part can be an axis structure, and one end of the sliding part can be connected to the matching part by means of threaded connection, plug-in connection or snap connection.

[0067] When the distance between the camera 11 and the zoom optical system 2 needs to be adjusted, the sliding part can be connected to the matching part, and the camera 11 can be driven to move relative to the zoom optical system 2 by moving the sliding part; when the distance between the camera 11 and the zoom optical system 2 is moderate and does not need to be adjusted or after the adjustment is completed, the connection between the sliding part and the matching part can be released, and the overall body 211 of the camera 11 can be reduced to achieve lightweight; at the same time, it is convenient to use one sliding part to adjust the cameras 11 of multiple imaging systems before the imaging system leaves the factory, thereby reducing production costs.

[0068] The sliding part can be purchased as an optional part for users to choose, thereby improving the flexibility of purchasing methods.

[0069] Second, the sliding portion and the matching portion are integrally formed.

[0070] Among them, the sliding part can form a whole with the matching part through injection molding or casting, that is, the sliding part and the camera 11 are a whole. During the adjustment process, force can be directly applied to the sliding part to drive the camera 11 to move relative to the zoom optical system 2. The adjustment is simple, and the relative movement between the sliding part and the matching part is avoided, thereby improving the accuracy of the adjustment.

[0071] In some embodiments, Figure 2 As shown, the mounting bracket 12 is covered on the camera 11 , the sliding portion passes through the first adjusting portion 121 and the outer end of the sliding portion protrudes relative to the outer surface of the mounting bracket 12 .

[0072] The mounting frame 12 is a frame structure. The mounting frame 12 is arranged outside the camera 11 and can protect and stabilize the camera 11.

[0073] When the sliding part is connected to the matching part, the sliding part passes through the first adjusting part 121, and the sliding part can move inside the first adjusting part 121, thereby adjusting the position of the camera 11. The outer end of the sliding part protrudes relative to the outer surface of the mounting frame 12, and the protruding outer end can be used as an operating handle to facilitate the user to manually adjust the position of the camera 11 relative to the zoom optical system 2, and the protruding design can increase the leverage of the sliding part, increase the stability of the camera 11, and make the user more labor-saving when adjusting the camera 11.

[0074] In some embodiments, the mounting bracket 12 is a hollow structure, and the camera 11 includes a fan. The fan of the camera 11 and the hollow structure of the mounting bracket 12 can enable the camera body 111 to fully dissipate heat, meet the use requirements of the imaging component 1 in a high temperature environment, and increase the use scenarios of the imaging component 1.

[0075] In some embodiments, the camera 11 includes a camera body 111 and a connecting member 112 connected to the camera body 111 , wherein the connecting member 112 is disposed between the mounting bracket 12 and the camera body 111 ; the connecting member 112 is provided with a second adjusting portion 1121 .

[0076] The camera body 111 is used to receive the light beam imaging of the zoom optical system 2 , and the connecting member 112 is used to connect the camera 11 and the mounting bracket 12 .

[0077] The connecting member 112 is arranged between the mounting frame 112 and the camera body 111, so that the mounting frame 112 can be suitable for camera bodies 111 of different specifications; and the second adjusting portion 1121 is arranged on the connecting member 112, that is, the second adjusting portion 1121 is externally placed on the camera body 111, and there is no need to make major structural improvements to the camera body 111, and the finished camera 111 can be directly used, which has strong compatibility and reduces production costs.

[0078] In some embodiments, the first adjustment parts 121 include multiple pairs, and each pair of first adjustment parts 121 is symmetrically arranged on opposite side walls of the mounting frame 12 ; the second adjustment parts 1121 include multiple pairs, and the second adjustment parts 1121 are arranged one-to-one with the first adjustment parts 121 .

[0079] Among them, the first adjustment part 121 is symmetrically arranged on the opposite side walls of the mounting frame 12, and the second adjustment part 1121 is symmetrically arranged on the opposite side walls of the camera 11. The symmetrical adjustment structure can balance the forces on both sides of the camera 11, reduce the deflection or vibration caused by improper installation or uneven adjustment, and thus improve the shooting stability and image quality; at the same time, multiple pairs of adjustment parts are evenly distributed on both sides of the mounting frame 12, so that the adjustment force can act more evenly on the camera body 111. When subjected to external impact or vibration, the symmetrical structure can better disperse and absorb these forces, reducing structural damage or inaccurate adjustment caused by excessive local force.

[0080] Exemplarily, when the mounting bracket 12 is covered on the camera 11, the outer wall of the camera 11 is parallel to the inner wall of the mounting bracket 12, the first adjustment part 121 includes two, and the two first adjustment parts 121 are symmetrically arranged on the opposite side walls of the mounting bracket 12, and the second adjustment part 1121 includes two, and the two second adjustment parts 1121 are symmetrically arranged on the opposite side walls of the connecting member 112, and by adjusting the second adjustment parts 1121 on the opposite sides of the connecting member 112, the camera 11 can be evenly stressed and move linearly relative to the mounting bracket 12.

[0081] In some embodiments, Figure 2 and Figure 5As shown, the zoom optical system 2 includes: a filter assembly 21 , and the filter assembly 21 includes: a body 211 , a filter rotation switching mechanism 212 , a plurality of filters 213 and a driving mechanism 214 .

[0082] The body 211 is connected to the mounting frame 12, and a photosensitive window is provided on the body 211; the filter rotation switching mechanism 212 is rotatably mounted on the body 211, and the filter rotation switching mechanism 212 is provided with a plurality of filter mounting positions 2121; multiple filters 213 are arranged in a one-to-one correspondence at the multiple filter mounting positions 2121; the driving mechanism 214 drives the filter rotation switching mechanism 212 to rotate, so that the target filter among the multiple filters 213 is rotated to the photosensitive window.

[0083] The target filter is one of the multiple filters 213 .

[0084] The body 211 is the main structure of the filter assembly 21, which is connected to the mounting frame 12 to ensure the stability and reliability of the filter assembly 21. The body 211 is provided with a photosensitive window, which is a channel for light to enter, through which the light can irradiate the sensor of the camera 11.

[0085] The filter rotation switching mechanism 212 is a rotatable mechanism, which is mounted on the body 211 and is used to carry and fix multiple filters 213. The filter rotation switching mechanism 212 is designed with multiple filter installation positions 2121, each of which can be placed with a specific filter 213. The user can rotate the filter rotation switching mechanism 212 to switch different filters 213 as needed.

[0086] The number of filter installation positions 2121 may be 2 or more, for example, 3 or 4.

[0087] Each filter 213 has its specific function. For example, the UV filter 213 can reduce the influence of ultraviolet light, the polarization filter 213 can reduce reflected light, and the neutral density filter 213 can reduce the intensity of light. The user can select a suitable filter 213 according to the shooting environment.

[0088] The driving mechanism 214 is the power part of the filter assembly 21 for realizing automatic switching of the filter 213. The driving mechanism 214 is connected to the filter rotation switching mechanism 212 by mechanical or electronic means, and can drive the filter rotation switching mechanism 212 to rotate. When the filter 213 needs to be switched, the driving mechanism 214 drives the filter rotation switching mechanism 212 to rotate, so that the filter 213 currently located in front of the photosensitive window is rotated to one side, and at the same time, another required filter 213 is rotated to the position of the photosensitive window.

[0089] In this embodiment, by providing the filter assembly 21, the user can rotate the filter rotation switching mechanism 212 to switch different filters 213 as needed, thereby increasing the usage scenarios.

[0090] In some embodiments, the multiple filters 213 include: a visible light filter 213 and a near infrared filter 213. By switching back and forth between the visible light filter 213 and the near infrared filter 213, the fog penetration requirement can be met.

[0091] In some embodiments, Figure 6 As shown, a driving gear 2141 is provided at the output end of the driving mechanism 214; a tooth structure is provided at the outer edge of the filter rotation switching mechanism 212; the filter assembly 21 also includes: at least one transmission gear 215, which is respectively meshed with the driving gear 2141 and the tooth structure.

[0092] The output end of the driving mechanism 214 is coupled to the filter rotation switching mechanism 212 through the transmission gear 215 , thereby improving the accuracy and sensitivity of the filter rotation switching mechanism 212 corresponding to the driving mechanism 214 .

[0093] By setting the transmission gear 215, the flexibility of the installation position of the filter rotation switching mechanism 212 can be achieved, the structural compactness of the filter assembly 21 is improved, and it is easy to integrate into an imaging system with limited space; at the same time, the transmission ratio of the transmission gear 215 can be set according to needs to meet specific transmission requirements.

[0094] In some embodiments, Figure 1 and Figure 2 As shown, the zoom optical system 2 includes: a focus lens group 216 and a zoom lens group 217 arranged in sequence along the optical path. The focus lens group 216, the zoom lens group 217 and the camera body 111 of the imaging assembly are arranged in sequence along the optical path.

[0095] The focusing lens group 216 can be composed of a fixed lens group in front of the optical system. The focusing lens group 216 is used to focus on the near and far targets to complete the focusing process.

[0096] During the focusing process, the focusing lens group 216 can convert the circular motion of the focusing motor into the linear motion of the focusing lens group 216. A cam mechanism with high transmission accuracy can be used in the focusing lens group 216, which has the advantages of accurate and flexible focusing and small backlash.

[0097] The zoom lens group 217 includes a magnification component and a compensation component. The controller can control the magnification component and the compensation component to move forward and backward in a straight line according to the zoom motion equation, thereby realizing the continuous variable focal length function of the molding system.

[0098] In some embodiments, Figure 2 As shown, the focusing motor of the focusing lens group 216 and the zooming motor of the zoom lens group 217 are distributed along the circumference of the imaging system to reduce the overall volume.

[0099] In some embodiments, Figure 2 As shown, the imaging system further includes a servo control board 3 and a power board.

[0100] The servo control board 3 is connected to the controller of the sighting instrument to complete the control of motors such as zoom, focus, aperture adjustment and color filter switching, and complete automatic focusing and automatic aperture control.

[0101] The servo control board 3 is electrically connected to the focus motor and the zoom motor.

[0102] The power board is used to receive the power input by the system, isolate and stabilize the voltage into 12V and output it to the camera 11 and the servo control board 3. At the same time, the power board can have the functions of preventing reverse connection at the input end, filtering or suppressing peak surges.

[0103] In some embodiments, Figure 2 As shown, the zoom optical system 2 and the imaging assembly 1 are arranged front and back and fixedly connected, the zoom optical system 2, the servo control board 3, the camera 11 and the power board are arranged in sequence along the optical path, and all the components form a whole.

[0104] In some embodiments, the mounting frame 12 is made of aluminum alloy to reduce the weight of the entire machine and achieve lightweight.
