In other words, in some embodiments of the present invention, these physical details are not necessary. In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.

[0036] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0037] See also Figure 1-9 In practical applications, the interference of ambient light is a common problem for imagers 1, especially in complex light environments, such as strong light, shadows, reflections, etc., which will affect the image quality and measurement accuracy. In order to avoid the influence of ambient light, a darkroom 2 is generally used to avoid the influence of ambient light;

[0038] The use of darkroom 2 will result in insufficient light during the acquisition process, affecting the imaging. Therefore, in an environment with insufficient light, the imager 1 may not be able to obtain sufficient brightness, resulting in an overly dark image, loss of details or increased noise. In this case, fill light is needed to increase the brightness of the image.

[0039] In the conventional supplementary light, the light source is set on the top of the target object. Since the substrate 153 supporting the target object is transparent, generally glass, reflection may occur, and the image is formed. Based on this, the present application provides an imager 1 with the function of preventing interference from external light. , including an imager 1 for imaging and a darkroom 2 wrapped outside the imager 1;

[0040] The darkroom 2 includes a frame 23 with an opening on one side, a door panel 21 is arranged at the opening of the frame 23, a sealing groove 24 is arranged on the front of the frame 23, a sealing strip 22 is arranged on the side of the door panel 21 corresponding to the frame 23, and the sealing strip 22 is sealed and connected to the sealing groove 24, so as 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 an imaging target object;

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

[0043] The 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 and has good structural stability and durability. A door panel 21 is provided at the opening of the frame 23 to close the darkroom 2 and ensure that the imaging environment in the darkroom 2 is completely isolated from the outside world.

[0044] A sealing groove 24 is designed on the front of the frame 23, and a sealing strip 22 is installed on the corresponding side of the door panel 21. The sealing strip 22 is tightly connected to the sealing groove 24 by elasticity or magnetic attraction, ensuring that the darkroom 2 forms a completely sealed space after closing to prevent external light from entering.

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

[0046] A placement area 15 is designed below the imaging assembly for placing the target to be imaged. The placement area 15 can be in the form of a platform or a tray to ensure that the target 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 transparency through electric current and has the ability to automatically adjust under different light conditions. It can be used as a transparent substrate 153, and can also be darkened when needed to reduce reflection and interference.

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

[0050] Furthermore, the inner side of the darkroom 2 may be coated with a light-absorbing material, such as the water-based acrylic paint released by Japan's Koyo Oriental Co., Ltd., which absorbs up to 99.2% of light;

[0051] By coating the light-absorbing material, the light-absorbing property of the material can be utilized to reduce the reflection of light during imaging, thereby avoiding the interference of reflected light during imaging and improving the quality of imaging.

[0052] The electrochromic glass plate 152 can automatically adjust the transparency according to the intensity of the ambient light. For example:

[0053] When the target object requires strong light exposure, the glass plate remains transparent to facilitate the passage of light.

[0054] When the external light is strong, the glass plate becomes darker through electric current adjustment, reducing the impact of reflection and stray light and avoiding interference with imaging.

[0055] The electrochromic glass plate 152 can take into account both the need for fill light and reflection protection, thereby ensuring imaging quality and measurement accuracy.

[0056] The imager 1 has a built-in fill light source (such as an LED light), and the light source can be controlled by software or manually to adjust the light intensity and direction.

[0057] The electrochromic glass plate 152 works in conjunction with the supplementary light source to provide sufficient light while preventing the reflection of the transparent substrate 153 from interfering with the imaging.

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

[0059] The electrochromic glass plate 152 can automatically adjust transparency according to actual needs, and can be used as a transparent substrate 153, and can be darkened 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 the traditional light-filling method.

[0060] The electrochromic glass plate 152 works in conjunction with the built-in supplementary light source to provide sufficient light while avoiding interference of reflection on imaging. This design can ensure high-quality imaging in both low-light and complex-light environments.

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

[0062] Through the sealed design of the darkroom 2 and the automatic adjustment function of the electrochromic glass plate 152, the complexity of manual adjustment of the light source and protective measures is reduced, the operation process is simplified, and the maintenance cost is reduced.

[0063] The imaging device 1 further comprises a base 11 , a machine platform 12 is arranged on the top of the base 11 , a force arm 14 is arranged on one side of the top of the machine platform 12 , and the force arm 14 is adapted to the imaging component 13 .

[0064] The imaging component 13 includes a rotating member 131 . A truncated cone-shaped mounting area 136 is disposed at the bottom of the rotating member 131 . One or more positioning holes 137 are formed in the mounting area 136 , and a camera and a fill light are installed thereon.

[0065] An electrochromic glass cover 133 is disposed at the bottom of the rotating member 131 , a pole piece 132 is disposed at the top of the electrochromic glass cover 133 , and a contact 135 is disposed at the top of the pole piece 132 .

[0066] A threaded area 134 is disposed on the outer side of the pole piece 132 , and a threaded groove is provided on the rotating member 131 at a position corresponding to the pole piece 132 , and is adapted to the threaded area 134 on the electrochromic glass cover 133 .

[0067] A truncated cone-shaped mounting area 136 is provided at the bottom of the rotating member 131 for mounting a camera and a fill light. One or more positioning holes 137 are provided at the mounting area 136 for fixing the camera and the fill light to ensure their stability and precise position on the rotating member 131 .

[0068] The rotation function of the rotating member 131 enables the imager 1 to flexibly adjust the imaging angle to meet the measurement requirements of different targets.

[0069] An electrochromic glass cover 133 is installed at the bottom of the rotating member 131, and a pole piece 132 is arranged on the top of the glass cover. The pole piece 132 is the core component of the electrochromic glass, and adjusts the transparency of the glass through electric current.

[0070] A contact 135 is provided on the top of the pole piece 132 for connecting to an external power source or a control circuit to adjust the transparency of the electrochromic glass.

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

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

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

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

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

[0076] When the light is strong or reflections need to be reduced, the glass cover becomes darker to reduce interference from external light and reflections.

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

[0078] The thread design also facilitates the user to disassemble and replace the electrochromic glass cover 133 to meet different application requirements. For example, different types of glass covers can be replaced when higher transparency or stronger protection is required.

[0079] The design of the rotating member 131 enables 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 realizes intelligent adjustment of transparency through the pole piece 132 and the contact 135, which can provide sufficient fill light and reduce the interference of external light and reflection. This design has significant advantages in an environment with complex light, ensuring imaging quality and measurement accuracy.

[0081] The threaded connection ensures the close combination of the electrochromic glass cover 133 and the rotating member 131, thereby improving the stability and durability of the device. At the same time, the threaded design also facilitates the user to disassemble and replace the glass cover, thereby enhancing the flexibility and maintainability of the device.

[0082] The electrochromic glass cover 133 works in conjunction with the fill light to provide sufficient light while avoiding interference of reflection on imaging. This design can ensure high-quality imaging in both low-light and complex-light environments.

[0083] The rotation function of the rotating member 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 the maintenance cost.

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

[0085] A connection area is provided inside the clamping area 151 . The connection area is located inside the clamping area 151 and extends toward the center, and is electrically connected through a spring contact.

[0086] The substrate 153 has a snap-fitting area 151 in the middle, which is used to fit the electrochromic glass plate 152. The snap-fitting area 151 can be a groove or a protrusion structure, which ensures the close connection between the electrochromic glass plate 152 and the substrate 153, and can provide stable support and prevent the glass plate from being displaced or falling off during the imaging process.

[0087] A connection area is provided on the inner side of the snap-on area 151 , and the connection area extends toward the center for electrically connecting to the contact 135 or the pole piece 132 of the electrochromic glass plate 152 . The connection area is usually made of a 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 through a reed. The reed 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, so that the electrochromic glass plate 152 can be easily connected to the substrate 153 during installation, while reducing the 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 clamping area 151 to ensure that it remains stable during the imaging process. The clamping area 151 can prevent the glass plate from shifting or falling off, thereby improving the stability and accuracy of imaging.

[0090] The connection area contacts the contact 135 or the pole piece 132 of the electrochromic glass plate 152 through the reed, thereby achieving a stable electrical connection. The elasticity of the reed enables the electrical connection to automatically adjust the contact pressure after the glass plate is installed, thereby ensuring smooth transmission of current, improving the transparency adjustment efficiency of the electrochromic glass plate 152, and reducing the adjustment failure problem caused by poor contact.

[0091] The integration of the clamping area 151 and the connection area makes the installation and electrical connection of the electrochromic glass plate 152 easier. The user can complete the fixing and electrical connection of the glass plate without additional operations, which reduces the installation steps and improves the convenience of use. The connection area contacts the contact 135 or the pole piece 132 of the electrochromic glass plate 152 through the reed to achieve a stable electrical connection. The elastic design of the reed ensures the smooth transmission of the current and improves the transparency adjustment efficiency of the electrochromic glass plate 152.

[0092] The stable electrical connection ensures that the transparency of the electrochromic glass plate 152 is more efficiently adjusted. By adjusting the transparency through the current, sufficient fill light can be provided, and the interference of external light and reflection can be reduced, which significantly improves the imaging quality and measurement accuracy.
