[0001] This invention relates to the field of imaging technology, specifically to an imaging device that prevents interference from external light. Background Technology

[0002] In practical applications of imaging instruments, interference from ambient light is a common problem, especially in environments with complex lighting conditions such as strong light, shadows, and reflections, all of which can affect image quality and measurement accuracy. To mitigate the effects of ambient light, a darkroom is typically used.

[0003] The use of a darkroom can result in insufficient light during the acquisition process, affecting image formation. Therefore, in low-light environments, the imaging equipment may not be able to obtain enough brightness, leading to images that are too dark, lack detail, or have increased noise. In such cases, supplemental lighting is needed to improve image brightness.

[0004] Traditional supplemental lighting places the light source on top of the target object. Since the substrate supporting the target object is transparent, usually made of glass, it may reflect light and affect the imaging. Based on this, this application provides an imaging device that prevents interference from external light. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an imaging device that prevents interference from external light. It solves the problem that in traditional supplementary lighting, where the light source is placed on top of the target object, reflections may occur due to the transparent substrate supporting the target object, typically made of glass, which can affect imaging.

[0013] As a further improvement of the present invention, the outer side of the electrode is provided with a threaded area, and the rotating member is provided with a threaded groove at the corresponding position of the electrode, which is adapted to the threaded area on the electrochromic glass cover.

[0014] As a further improvement of the present invention, a snap-fit ​​area is provided in the middle of the substrate, and the snap-fit ​​area is adapted to the electrochromic glass plate.

[0015] As a further improvement of the present invention, a connecting area is provided on the inner side of the snap-fit ​​area, the connecting area being located on the inner side of the snap-fit ​​area and extending towards the center, and being electrically connected via a spring contact.

[0016] As a further improvement of the present invention, the inner side of the darkroom is coated with a light-absorbing material to reduce light reflection and improve imaging accuracy.

[0019] Electrochromic glass panels can automatically adjust their transparency according to actual needs, serving as both a transparent substrate and darkening when necessary to reduce reflections and stray light.

However, it should be understood that these physical details are not intended to limit the invention. That is, in some embodiments of the invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in the illustrations in a simple schematic manner.

[0036] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are feasible for those skilled in the art.

[0037] Please see Figure 1-9 In practical applications, ambient light interference is a common problem for image analyzers 1, especially in environments with complex lighting conditions such as strong light, shadows, and reflections, which can affect image quality and measurement accuracy. To mitigate the impact of ambient light, a darkroom 2 is generally used.

[0038] The use of darkroom 2 will result in insufficient light during the acquisition process, affecting imaging. Therefore, in an environment with insufficient light, imager 1 may not be able to obtain enough brightness, resulting in images that are too dark, lack detail, or have increased noise. In this case, supplemental lighting is needed to improve the brightness of the image.

[0039] Traditional supplemental lighting places the light source on top of the target object. Since the substrate 153 supporting the target object is transparent, usually made of glass, reflections may occur, affecting image formation. Based on this, this application provides an imaging device 1 that prevents interference from external light, including an imaging device 1 for imaging and a darkroom 2 enclosing the outside of the imaging device 1;

[0040] Darkroom 2 includes a frame 23 with an opening on one side, a door panel 21 is provided at the opening of the frame 23, a sealing groove 24 is provided on the front of the frame 23, and a sealing strip 22 is provided on the side of the door panel 21 corresponding to the frame 23. The sealing strip 22 is sealed and connected to the sealing groove 24 to form a completely sealed darkroom 2.

[0041] The imaging device 1 includes an imaging component 13, and a placement area 15 is provided below the imaging component 13 for placing the target object to be imaged.

[0042] The placement area 15 includes a substrate 153 on which an electrochromic glass plate 152 is mounted for supplemental imaging of the target object.

[0043] Darkroom 2 adopts a frame 23 structure with an opening on one side. The frame 23 can be made of metal or high-strength plastic, which has good structural stability and durability. A door panel 21 is set at the opening of the frame 23 to close the darkroom 2 and ensure that the imaging environment inside the darkroom 2 is completely isolated from the outside world.

[0044] The frame 23 has a sealing groove 24 on the front, and a sealing strip 22 is installed on the corresponding side of the door panel 21. The sealing strip 22 and the sealing groove 24 are tightly connected by elasticity or magnetic attraction to ensure that the darkroom 2 forms a completely sealed space after being closed, preventing outside light from entering.

[0045] The imaging device 1 includes imaging components (such as a high-resolution camera, lens, and sensor) for capturing images of the target object.

[0046] A placement area 15 is designed below the imaging component for placing the target object to be imaged. The placement area 15 can be in the form of a platform or a tray to ensure that the target object remains stable during imaging.

[0047] The substrate 153 of the placement area 15 is made of a transparent material (such as acrylic or glass) and is used to support the target object.

[0048] An electrochromic glass plate 152 is mounted on the substrate 153. The electrochromic glass plate 152 adjusts its transparency by means of an electric current and has the ability to automatically adjust under different lighting conditions. It can be used as a transparent substrate 153 or darkened when needed to reduce reflection and interference.

[0049] Darkroom 2 forms a completely sealed space through the tight connection of sealing groove 24 and sealing strip 22. The sealing strip 22 can be made of rubber or silicone, which has good elasticity and sealing performance, ensuring that the interior of darkroom 2 is completely isolated from the outside world after the door panel 21 is closed, preventing external light from interfering with the imaging of imager 1.

[0050] Furthermore, the inside of darkroom 2 can be coated with a light-absorbing material, such as water-based acrylic paint released by Koyo Oriental Co., Ltd. of Japan, which has a light absorption rate of up to 99.2%.

[0051] By coating with light-absorbing materials, the light-absorbing properties of the materials can be utilized during imaging to reduce light reflection, thereby avoiding interference from reflected light and improving image quality.

[0052] Electrochromic glass panel 152 can automatically adjust its transparency according to the intensity of ambient light. For example:

[0053] When the target object needs strong light, the glass plate remains transparent to allow light to pass through.

[0054] When the ambient light is strong, the glass plate is dimmed by adjusting the current to reduce the influence of reflected and stray light and avoid interfering with imaging.

[0055] The electrochromic glass plate 152 can balance the need for supplementary lighting and reflection protection, ensuring imaging quality and measurement accuracy.

[0056] The imager 1 has a built-in supplementary light source (such as an LED light), and the light intensity and direction can be adjusted by software or manual control.

[0057] The electrochromic glass plate 152 works in conjunction with the supplementary light source to provide sufficient light while avoiding interference with imaging caused by reflection from the transparent substrate 153.

[0058] The design of the darkroom 2 frame 23, sealing groove 24 and sealing strip 22 ensures that the interior of the darkroom 2 is completely isolated from the outside world, avoiding interference from ambient light such as strong light, shadows and reflections, and significantly improving imaging quality and measurement accuracy.

[0059] The electrochromic glass panel 152 can automatically adjust its transparency according to actual needs. It can be used as a transparent substrate 153, or it can darken when needed to reduce the impact of reflection and stray light. This design effectively solves the problem of reflection of the transparent substrate 153 in traditional supplementary lighting methods.

[0060] The electrochromic glass panel 152 works in conjunction with the built-in supplemental lighting source to provide ample light while avoiding interference from reflections on the image. This design ensures high-quality imaging in both low-light and complex lighting environments.

[0061] The intelligent adjustment function of the electrochromic glass plate 152 enables the imager 1 to flexibly adapt to different lighting conditions and application scenarios. Whether in a well-lit laboratory environment or a complex industrial site, the imager 1 can work stably.

[0062] The sealed design of darkroom 2 and the automatic adjustment function of electrochromic glass plate 152 reduce the complexity of manually adjusting the light source and protective measures, simplify the operation process, and reduce maintenance costs.

[0063] The imaging device 1 also includes a base 11, a platform 12 is provided on the top of the base 11, and a lever 14 is provided on one side of the top of the platform 12. The lever 14 is adapted to the imaging component 13.

[0064] The imaging component 13 includes a rotating part 131. The bottom of the rotating part 131 is provided with a frustum-shaped mounting area 136. One or more positioning holes 137 are provided in the mounting area 136, and a camera and a fill light are installed thereon.

[0065] The bottom of the rotating component 131 is provided with an electrochromic glass cover 133, the top of the electrochromic glass cover 133 is provided with an electrode 132, and the top of the electrode 132 is provided with a contact 135.

[0066] The outer side of the electrode 132 is provided with a threaded area 134, and the rotating part 131 is provided with a threaded groove at the corresponding position of the electrode 132, which is adapted to the threaded area 134 on the electrochromic glass cover 133.

[0067] The bottom of the rotating component 131 has a frustum-shaped mounting area 136 for mounting a camera and a fill light. One or more positioning holes 137 are provided in the mounting area 136 to fix the camera and fill light and ensure their stability and precise position on the rotating component 131.

[0068] The rotation function of the rotating component 131 enables the imager 1 to flexibly adjust the imaging angle to adapt to the measurement needs of different targets.

[0069] An electrochromic glass cover 133 is mounted on the bottom of the rotating component 131, and an electrode 132 is provided on the top of the glass cover. The electrode 132 is the core component of the electrochromic glass, which adjusts the transparency of the glass by means of an electric current.

[0070] The top of the electrode 132 is provided with a contact 135 for connecting to an external power supply or control circuit to adjust the transparency of the electrochromic glass.

[0071] The outer side of the electrode 132 is designed with a threaded area 134, and the rotating component 131 has a threaded groove at the corresponding position. The threaded area 134 and the threaded groove are adapted to ensure a tight connection between the electrochromic glass cover 133 and the rotating component 131.

[0072] The threaded connection not only improves installation stability but also facilitates disassembly and maintenance, allowing users to replace or adjust the electrochromic glass cover 133 as needed.

[0073] The rotation function of the rotating component 131 allows the imager 1 to flexibly adjust the imaging angle to adapt to targets of different shapes and sizes. For example, when measuring irregular objects, the position of the camera and the supplementary light can be adjusted by the rotating component 131 to ensure the comprehensiveness and accuracy of the imaging.

[0074] The electrochromic glass cover 133 is connected to an external power source via electrode 132 and contact 135, and can automatically adjust its transparency according to ambient light or user needs. For example:

[0075] When there is insufficient light, the glass cover remains transparent, allowing the light from the supplemental lighting to pass through and provide sufficient illumination.

[0076] When the light is strong or when it is necessary to reduce reflection, the glass cover darkens to reduce interference from external light and reflection.

[0077] The threaded connection ensures a tight fit between the electrochromic glass cover 133 and the rotating part 131, improving the stability and durability of the equipment.

[0078] The threaded design also facilitates the removal and replacement of the electrochromic glass cover 133 by users to adapt to different application needs. For example, different types of glass covers can be replaced when higher transparency or stronger protection is required.

[0079] The design of the rotating component 131 allows the imager 1 to flexibly adjust the imaging angle to adapt to targets of different shapes and sizes. This design significantly improves the applicability and measurement accuracy of the imager 1.

[0080] The electrochromic glass cover 133 achieves intelligent adjustment of transparency through electrodes 132 and contacts 135, providing ample supplemental lighting while reducing interference from external light and reflections. This design offers significant advantages in complex lighting environments, ensuring imaging quality and measurement accuracy.

[0081] The threaded connection ensures a tight fit between the electrochromic glass cover 133 and the rotating component 131, improving the stability and durability of the equipment. At the same time, the threaded design facilitates user disassembly and replacement of the glass cover, enhancing the flexibility and maintainability of the equipment.

[0082] The electrochromic glass cover 133 works in conjunction with the fill light to provide ample illumination while avoiding reflections that could interfere with imaging. This design ensures high-quality imaging in both low-light and complex lighting environments.

[0083] The rotation function of the rotating component 131 and the intelligent adjustment function of the electrochromic glass cover 133 reduce the complexity of manually adjusting the light source and protective measures, simplify the operation process, and reduce maintenance costs.

[0084] A snap-fit ​​area 151 is provided in the middle of the substrate 153, and the snap-fit ​​area 151 is adapted to the electrochromic glass plate 152.

[0085] A connection area is provided on the inner side of the snap-fit ​​area 151. The connection area is located on the inner side of the snap-fit ​​area 151 and extends towards the center, and is electrically connected by a spring contact.

[0086] The substrate 153 has a snap-fit ​​area 151 in the middle for fitting with the electrochromic glass plate 152. The snap-fit ​​area 151 can be a groove or a protrusion structure. The snap-fit ​​area 151 ensures a tight connection between the electrochromic glass plate 152 and the substrate 153, providing stable support and preventing the glass plate from shifting or falling off during imaging.

[0087] A connection area is provided on the inner side of the snap-fit ​​area 151. The connection area extends towards the center and is used to make electrical connections with the contacts 135 or electrode 132 of the electrochromic glass plate 152. The connection area is usually made of conductive material (such as metal) to ensure good electrical contact with the electrochromic glass plate 152.

[0088] The connection area is electrically connected to the electrochromic glass plate 152 via a spring. The spring is an elastic conductive element that can automatically adjust the contact pressure according to the thickness of the glass plate to ensure a stable electrical connection. This allows the electrochromic glass plate 152 to be easily connected to the substrate 153 during installation, while reducing contact resistance and improving the transparency adjustment efficiency of the electrochromic glass plate 152.

[0089] The electrochromic glass plate 152 is tightly connected to the substrate 153 via the snap-fit ​​area 151, ensuring its stability during imaging. The snap-fit ​​area 151 prevents the glass plate from shifting or falling off, thereby improving the stability and accuracy of imaging.

[0090] The connection area contacts the contacts 135 or electrode 132 of the electrochromic glass plate 152 via a spring, achieving a stable electrical connection. The elasticity of the spring allows the electrical connection to automatically adjust the contact pressure after the glass plate is installed, ensuring smooth current transmission, improving the transparency adjustment efficiency of the electrochromic glass plate 152, and reducing adjustment failures caused by poor contact.

[0091] The integration of the snap-fit ​​area 151 and the connection area simplifies the installation and electrical connection of the electrochromic glass panel 152. Users can fix the glass panel and make electrical connections without additional steps, reducing installation procedures and improving ease of use. The connection area achieves a stable electrical connection through contact between the spring contacts and the contacts 135 or electrode plates 132 of the electrochromic glass panel 152. The elastic design of the spring contacts ensures smooth current transmission and improves the transparency adjustment efficiency of the electrochromic glass panel 152.

[0092] A stable electrical connection ensures more efficient transparency adjustment of the electrochromic glass plate 152. By adjusting the transparency through current, sufficient supplementary lighting can be provided while reducing interference from external light and reflections, significantly improving image quality and measurement accuracy.
