[0020] Compared with the prior art, the utility model has the beneficial effects that:

[0021] The device adopts an aspheric lens, compared with a traditional spherical lens, the aspheric lens can effectively reduce aberration. The reduction of aberration makes the light more accurate in the focusing process, thereby significantly improving the clarity and quality of imaging. In different application scenarios, industrial detection and security monitoring can provide clear and accurate images, which helps to more accurately identify the detailed features of the target object.

[0022] The six annular array distributed ambient light sensors can detect the ambient light intensity and spectral characteristics entering the device in real time and comprehensively. The dimming optical circuit board adjusts the light parameters by accurately calculating and controlling the variable resistor through the microcontroller according to the information fed back by these sensors. At the same time, the diaphragm can also adjust the aperture size according to the dimming control result. This self-adaptive dimming function ensures that the imaging device can obtain the best light quantity and quality under different lighting conditions, thereby realizing stable and high-quality imaging effect. Whether in strong light direct radiation or weak light environment, clear and contrast appropriate images can be shot.

[0023] The antireflection film lens at the tail of the connecting cylinder reduces light reflection and improves light transmittance. This means that more light can enter the imaging system, making full use of limited light resources and further improving the brightness and clarity of imaging. At the same time, it also reduces the interference of stray light caused by light reflection on imaging, making the image more pure.

[0024] The four shockproof air cushions adsorbed between the imaging device shell body and the lens fixing seat play a good buffering role. When the device is subjected to external vibration, such as being installed in a vehicle or an environment where industrial equipment may vibrate, the shockproof air cushion can effectively absorb and disperse vibration energy, protecting the internal precise optical elements and circuits from damage. This greatly improves the stability and reliability of the device, reducing the risk of imaging blur or equipment failure caused by vibration.

[0025] The protective side plates and the side plate reinforcing ribs embedded on both sides of the imaging device shell provide firm external protection for the device. The protective side plates can prevent external objects from colliding and scratching the device, and the side plate reinforcing ribs enhance the strength of the protective side plates and improve the impact resistance of the entire device. This enables the device to better withstand various physical damages in complex working environments and prolongs the service life of the device.

[0026] The plate body fixing screw holes on the outer surface of the imaging device mounting plate facilitate the use of bolt fixing pieces to mount the device in the appropriate position. The imaging device support plate provides additional support to ensure firm installation of the device. At the same time, the data line oval perforations on the surface of the imaging device support plate facilitate the arrangement and connection of the data line of the imaging device, making the entire installation process more convenient and efficient.

[0027] The imaging calibration mark hole provided on the upper part of the auxiliary light shield provides convenience for imaging calibration. During installation and use, the position and angle of the imaging device can be accurately adjusted through the calibration mark hole to ensure the accuracy and consistency of imaging. This helps to quickly complete the debugging work of the device, improves work efficiency, and ensures the stability of the imaging quality.

[0028] The dimming programming port connected to the dimming optical circuit board allows users to modify and update the dimming program. The internal conductive copper wire ensures the stability of signal transmission. This enables the device to flexibly adjust the dimming strategy according to different application requirements and scene characteristics, further optimizing the imaging effect. For example, on different industrial production lines, personalized dimming schemes can be achieved through programming according to the characteristics of the products and detection requirements.

[0029] The light source port on one side of the dimming optical circuit board can be connected to an external light source. When the ambient light is insufficient, the microcontroller can control the light source connected to the light source port to turn on, providing additional light for imaging. This light source supplement function enhances the adaptability of the device in low light environments, expands the use range of the device, and enables it to work normally under more complex lighting conditions.

[0039] Embodiment 1: please refer to Figures 1-5 An adaptive dimming optical engineering imaging device, comprising an imaging device outer shell 1 and a sunshade mounting plate 2 arranged on the front plate of the imaging device outer shell 1, wherein the device lens cover 3 is embedded in the inner plate of the sunshade mounting plate 2, the aspheric lens 4 is fixed in the inner ring groove of the device lens cover 3, and the ambient light sensor 5 is connected to the annular outer edge of the aspheric lens 4, and the ambient light sensor 5 is provided with six, sequentially arranged in a ring shape. The dimming optical circuit board 6 is electrically installed in the inside of the imaging device outer shell 1, the memory chip 7 is electrically connected to the center end circuit of the dimming optical circuit board 6, and the microcontroller 8 is electrically installed on the right side of the memory chip 7.

[0040] The left half of the dimming optical circuit board 6 is connected with a dimming programming port 9 and a variable resistor 10, and the dimming programming port 9 is provided with a conductive copper wire. A connecting cylinder 11 is installed between the device lens cover 3 and the dimming optical circuit board 6, the front end of the connecting cylinder 11 is connected with the device lens cover 3, the tail is provided with an anti-reflection film lens 12, and the outer surface of the anti-reflection film lens 12 is connected with a diaphragm 13.

[0041] A light source port 14 is electrically installed on one side of the dimming optical circuit board 6. An imaging lens barrel 15 is embedded in the sunshade mounting plate 2, and the device lens cover 3 is located in the imaging lens barrel 15, and the front end of the imaging lens barrel 15 is fixed with an auxiliary light shield 16. A lens fixing seat 17 is arranged below the imaging device housing 1, and four shockproof air cushions 18 are adsorbed between the imaging device housing 1 and the lens fixing seat 17. The tail end of the lens fixing seat 17 is fixed with an imaging device mounting plate 19, and the outer surface of the imaging device mounting plate 19 is provided with a plate body fixing screw hole 20. An imaging device support plate 21 is installed between the lens fixing seat 17 and the imaging device mounting plate 19, and the surface of the imaging device support plate 21 is provided with a data line ellipse perforation 22. The front end of the imaging device mounting plate 19 is provided with an imaging device data line 23.

[0042] The imaging device housing 1 is embedded with a protective side plate 24 on both sides, and the outer plate of the protective side plate 24 is fixed with a side plate reinforcing rib 25. An imaging calibration mark hole 26 is arranged above the auxiliary light shield 16.

[0043] The working principle of the adaptive dimming optical engineering imaging device: the external light first passes through the auxiliary light shield 16 on the sunshade mounting plate 2, and the auxiliary light shield 16 plays a role in preliminary shielding of stray light, so that the light entering the device is more pure. After the light passes through the auxiliary light shield 16, it enters the device lens cover 3 in the imaging lens barrel 15. The aspheric lens 4 in the annular groove in the device lens cover 3 focuses the light. The aspheric lens 4 can reduce aberration, improve the clarity and quality of imaging, and make the light better converge.

[0044] Six environmental light sensors 5 are connected in a ring array on the outer ring of the aspheric lens 4. These environmental light sensors 5 detect the environmental light intensity and spectral characteristic information entering the device in real time, and convert the detected signals into electrical signals.

[0045] The environmental light sensor 5 transmits the detected electrical signals to the dimming optical circuit board 6 inside the imaging device housing 1. The dimming optical circuit board 6 serves as the control core of the entire device, receiving and processing these signals. The memory chip 7 connected to the central circuit of the dimming optical circuit board 6 is used to store preset dimming parameters and related imaging data. The microcontroller 8 reads these data from the memory chip 7 and, combined with the signals from the environmental light sensor 5, performs analysis and calculation.

[0046] The dimming programming port 9 connected to the left half of the dimming optical circuit board 6 can be used to modify and update the dimming program, and the conductive copper wire inside ensures the stability of signal transmission. The variable resistor 10 adjusts the resistance value in the circuit according to the calculation results of the microcontroller 8, thereby achieving precise adjustment of light intensity and other optical parameters.

[0047] After the light transmission is focused by the aspheric lens 4 and the environmental light is detected, the light enters the connecting cylinder 11. The tail of the connecting cylinder 11 is provided with an anti-reflection film lens 12, which can reduce light reflection and increase light transmission, so that more light can continue to transmit backward.

[0048] Iris adjustment: The iris 13 connected to the outer surface of the anti-reflection film lens 12 can adjust the aperture size according to the results of dimming control, further control the amount of light entering the imaging system, to adapt to different environmental light conditions.

[0049] Light source supplement: The light source port 14 electrically installed on one side of the dimming optical circuit board 6 can be connected to an external light source. When the environmental light is insufficient, the microcontroller 8 can control the light source connected to the light source port 14 to turn on, providing additional light for imaging to ensure the quality of imaging.

[0050] The imaging device is installed through the imaging device mounting plate 19, and the plate body fixing screw hole 20 on the outer surface of the imaging device mounting plate 19 can be fixed to the appropriate position using a bolt fixing member. The imaging device support plate 21 provides additional support for the device, and the data line ellipse perforation 22 on its surface facilitates the arrangement and connection of the imaging device data line 23.

[0051] Four shock-absorbing air cushions 18 are adsorbed between the imaging device housing 1 and the lens fixing seat 17, which can effectively buffer the influence of external vibration on the device, protect the internal optical elements and circuits from damage caused by vibration, and ensure the stability of imaging.

[0052] The protective side plates 24 embedded on both sides of the imaging device housing 1 protect the device, and the side plate reinforcing ribs 25 enhance the strength of the protective side plates 24, further improving the overall protection performance of the device.

[0053] The imaging calibration mark hole 26 arranged above the auxiliary light shield 16 can be used for imaging calibration. During installation and use, the position and angle of the imaging device can be accurately adjusted through the calibration mark hole 26 to ensure the accuracy and consistency of imaging.

[0054] Example 2: Device installation and preliminary debugging:

[0055] Determine the installation location: First, according to the actual imaging needs, select a suitable installation location. For example, if used for detecting product appearance defects on the production line, the installation location can be determined at a suitable height directly above the production line to ensure that the entire product can be clearly photographed.

[0056] Fix the device: Use the bolt to pass through the plate body fixing screw hole 20 on the outer surface of the imaging device mounting plate 19 to firmly install the device at the pre-selected location. At the same time, the imaging device support plate 21 provides additional stable support for the device to ensure that the device does not shake after installation.

[0057] Connect the data line: Arrange the imaging device data line 23 through the data line elliptical perforation 22 on the surface of the imaging device support plate 21, and connect it with the external data processing equipment to prepare for subsequent data transmission.

[0058] Imaging calibration: With the help of the imaging calibration mark hole 26 above the auxiliary light shield 16, the position and angle of the imaging device are accurately adjusted. By observing the relative position relationship between the calibration mark hole and the calibration target, the device is continuously fine-tuned until the imaging reaches the best accuracy and consistency, ensuring that the photographed image does not have any tilt or distortion problems.

[0059] Example 3: Working conditions in strong light environment:

[0060] When the device is in a strong light environment, including direct sunlight outdoors, the external light first passes through the auxiliary light shield 16. The auxiliary light shield 16 effectively blocks part of the direct strong light and stray light, making the light entering the imaging lens barrel 15 relatively soft and pure.

[0061] The light passes through the aspherical lens 4 in the lens cover 3 of the device, which focuses the light and reduces aberration, improving the clarity of the image. At this time, the six ambient light sensors 5 distributed on the annular outer edge of the aspherical lens 4 detect that the light intensity is high and quickly transmit the detected electrical signal to the dimming optical circuit board 6.

[0062] After receiving the signal from the ambient light sensor 5, the microcontroller 8 on the dimming optical circuit board 6 reads the preset dimming parameters from the memory chip 7 and performs analysis and calculation. Since the light is too strong, the microcontroller 8 controls the variable resistor 10 to adjust the circuit parameters and sends instructions to the diaphragm 13.

[0063] The diaphragm 13 reduces the size of the aperture according to the instructions, reduces the amount of light entering the imaging system, and avoids overexposure of the image due to excessive light. After the dimming process, the light passes through the anti-reflection film lens 12 connected to the tail of the cylinder 11 to further reduce reflection and improve light transmittance, and finally enters the imaging system for imaging.

[0064] Example 4: Working condition in weak light environment:

[0065] In a weak light environment, after the external light enters the device, the ambient light sensor 5 detects that the light intensity is low and converts this information into an electrical signal to transmit to the dimming optical circuit board 6.

[0066] After receiving the signal, the microcontroller 8 also reads the relevant parameters from the memory chip 7 for analysis to determine that the current light intensity is insufficient to meet the normal imaging requirements.

[0067] The microcontroller 8 controls the external light source connected to the light source port 14 on one side of the dimming optical circuit board 6 to turn on, providing additional light for imaging. At the same time, according to the real-time light intensity feedback from the ambient light sensor 5, the microcontroller 8 performs fine dimming operation through the variable resistor 10 and the diaphragm 13.

[0068] The variable resistor 10 adjusts the circuit to gradually increase the brightness of the supplemental light source to an appropriate level, and the diaphragm 13 appropriately increases the aperture size to allow more light to enter the imaging system. After such dimming processing, the device can capture clear and properly bright images in a weak light environment

[0069] Working process of the adaptive dimming optical engineering imaging device:

[0070] Through the plate body fixing screw holes 20 on the outer surface of the imaging device mounting plate 19, use the bolt fixing piece to fix the device in the appropriate position; use the imaging device support plate 21 to provide additional support, and arrange and connect the imaging device data line 23 through the data line elliptical perforation 22 to provide power and transmit data for the device.

[0071] With the help of the imaging calibration mark hole 26 on the top of the auxiliary light shield 16, the position and angle of the imaging device are accurately adjusted to ensure the accuracy and consistency of imaging.

[0072] The external light rays first pass through the auxiliary light shield 16 at the front end of the imaging lens barrel 15, and the auxiliary light shield 16 blocks part of the stray light, making the light entering the device purer.

[0073] The light rays that have undergone preliminary filtering enter the device lens cover 3 inside the imaging lens barrel 15, and the aspheric lens 4 in the inner ring groove of the device lens cover 3 focuses the light rays, reduces aberration, and improves imaging clarity.

[0074] The six ambient light sensors 5 arranged in a ring array on the outer ring of the aspheric lens 4 detect the intensity and spectral characteristics of the ambient light entering the device in real time and convert these signals into electrical signals.

[0075] The ambient light sensors 5 transmit the converted electrical signals to the dimming optical circuit board 6 inside the imaging device housing 1.

[0076] The memory chip 7 connected to the central circuit of the dimming optical circuit board 6 stores preset dimming parameters and related imaging data. The microcontroller 8 on the right side reads these data from the memory chip 7 and analyzes and calculates them in combination with the signals from the ambient light sensors 5.

[0077] According to the calculation results of the microcontroller 8, the variable resistor 10 connected to the left half of the dimming optical circuit board 6 adjusts the resistance value in the circuit, thereby accurately adjusting the light intensity and other optical parameters. At the same time, the dimming program can also be modified and updated through the dimming programming port 9 (which has a conductive copper wire inside to ensure stable signal transmission).

[0078] The light rays that have undergone focusing and dimming control enter the connecting cylinder 11, and the antireflection film lens 12 at the tail of the connecting cylinder 11 reduces light reflection and increases light transmission, allowing more light to continue to transmit backward.

[0079] The diaphragm 13 on the outer surface of the antireflection film lens 12 adjusts the aperture size according to the dimming control results, further accurately controlling the amount of light entering the imaging system.

[0080] When the ambient light is insufficient, the microcontroller 8 controls the external light source connected to the light source port 14 electrically installed on one side of the dimming optical circuit board 6 to turn on, providing additional light for imaging to ensure imaging quality.

[0081] After the above series of processing, the light rays complete the imaging process, and the imaging data is transmitted to external equipment for storage or further processing through the imaging device data line 23.

[0082] During the operation of the imaging device, the four shock-absorbing air cushions 18 adsorbed between the imaging device housing 1 and the lens fixing seat 17 buffer the influence of external vibration on the device, protecting the internal optical elements and circuits from damage caused by vibration and ensuring the stability of imaging. The protective side plates 24 embedded on both sides of the imaging device housing 1 provide protection for the device, and the side plate reinforcing ribs 25 enhance the strength of the protective side plates 24, improving the overall protection performance of the device and preventing damage to the device caused by external objects.

[0083] The above examples are only used to illustrate the technical solutions described in the utility model and do not limit the utility model. Although the utility model has been described in detail with reference to the above various embodiments, the utility model is not limited to the above specific embodiments, and therefore any modification or substitution of the utility model; and all technical solutions and improvements that do not deviate from the spirit and scope of the utility model are all covered in the scope of the claims of the utility model.
