[0036] During the research, the applicant found that in the field of image acquisition equipment, the design of the light source device is crucial to obtaining high-quality images. The traditional light source device may directly illuminate the camera lens, which may cause overexposure or produce halos at the edges of the photographed object. This may affect the clarity, contrast and color accuracy of the image, and reduce the quality and authenticity of the image.

[0037] Based on this, the light source device and image acquisition device provided in the embodiments of the present application can provide stable and high-quality lighting effects in various shooting scenes, and can avoid the occurrence of problems such as overexposure and halo as much as possible. The light source device provided in the embodiments of the present application has a simple structural design, is easy to implement and control, and can show good performance under different shooting conditions. In addition, applying the light source device provided in the embodiments of the present application to the image acquisition device can avoid the occurrence of problems such as overexposure and halo as much as possible, and improve the quality of the image acquired by the image acquisition device.

[0038] Please see Figure 1 , Figure 1 A structural schematic diagram of a light source device provided in an embodiment of the present application; the present application provides a light source device 100, which includes a light source 130, a light source surface 110 having a long end 111 of the light source surface, and a shading surface 120 having a long end 121 of the shading surface.

[0039] like Figure 1 As shown, the light source device 100 provided in the embodiment of the present application includes a long side direction L and a short side direction D, and the long side direction L and the short side direction D are perpendicular to each other.

[0040] The light source surface long end 111 and the light shielding surface long end 121 are arranged to intersect in the long side direction L and form a light angle r. The light source surface 110 can emit light, and the formed light angle r can control the irradiation direction and distribution of the light.

[0041] The light source 130 is disposed on the inner side of the light source surface 110 within the light angle r. It should be noted that the length of the long end 121 of the shading surface in the long side direction L is not less than the length of the light source 130 in the long side direction L, thereby ensuring that the shading surface 120 can effectively block the light emitted by the light source 130 and change the route and distribution of the illumination.

[0042] The light source surface 110 is configured to provide illumination. The existence of the light angle r can ensure that the light source device 100 emits illumination. The light shielding surface 120 is configured to block part of the illumination. In some cases, the illumination is not directly irradiated on the target object.

[0043] pass Figure 1 It can be seen that the light source device 100 provided in the embodiment of the present application forms a light angle r by reasonably configuring the light source surface 110 and the light shielding surface 120. Light can be emitted through the light angle r, which can ensure stable lighting for the application scenario of the light source device 100; and because the light shielding surface 120 forms a partial shielding of the light source 130 in the light source surface 110, it can prevent the light source 130 from emitting light directly to the target object, greatly avoiding the occurrence of overexposure, and reducing the scattering of light around the camera lens, thereby reducing the generation of halo. On the other hand, the light source device 100 provided in the embodiment of the present application has a simple and practical structure, is easy to implement and control, can show good performance under various shooting conditions, and has high practicality and operability.

[0044] Please see Figure 2 , Figure 2 Another structural schematic diagram of the light source device of the embodiment of the present application; the light source device 100 provided in the embodiment of the present application further includes a first fixing mechanism 140 and a second fixing mechanism 150. The light source surface 110 further includes a first short end 112 of the light source surface and a second short end 113 of the light source surface, and the light shielding surface 120 further includes a first short end 122 of the light shielding surface and a second short end 123 of the light shielding surface.

[0045] The first fixing mechanism 140 is connected to the first short end 112 of the light source surface and the first short end 122 of the light shielding surface in the short side direction D, and the second fixing mechanism 150 is connected to the second short end 113 of the light source surface and the second short end 123 of the light shielding surface in the short side direction D.

[0046] The first fixing mechanism 140 and the second fixing mechanism 150 are configured to fix the light source surface 110 and the light shielding surface 120 in the short side direction D.

[0047] pass Figure 2It can be seen that the light source device 100 provided in the embodiment of the present application fixes the light source surface 110 and the shading surface 120 in the short side direction D through the first fixing mechanism 140 and the second fixing mechanism 150, thereby ensuring the stability and reliability of the light source device 100 and making it less susceptible to external interference during use.

[0048] Please see Figure 3 , Figure 3 Another structural schematic diagram of the light source device provided in the embodiment of the present application; in an optional implementation of the embodiment of the present application, the light source device 100 also includes a plurality of fixing members 160 and a first fixed connecting portion 170 and a second fixed connecting portion 180 respectively having a first fixing hole 191, and the first fixing mechanism 140 and the second fixing mechanism 150 respectively have a second fixing hole 192.

[0049] The fixing member 160 passes through the first fixing hole 191 and the second fixing hole 192 to connect the first fixing connection part 170 with the first fixing mechanism 140. The fixing member 160 passes through the first fixing hole 191 and the second fixing hole 192 to connect the second fixing connection part 180 with the second fixing mechanism 150.

[0050] The first fixed connection portion 170 and the second fixed connection portion 180 are configured to connect to an external structure.

[0051] It should be noted that the fixing member 160 can be a bolt and a nut, the bolt passes through the first fixing hole 191 and the second fixing hole 192, and the nut is fixed on the side where the bolt passes out, thereby achieving the fixation of the first fixing mechanism 140 and the first fixed connection part 170, and the fixation of the second fixing mechanism 150 and the second fixed connection part 180.

[0052] pass Figure 3 It can be known that the light source device 100 provided in the embodiment of the present application fixes the first fixing mechanism 140 to the first fixed connection part 170, and the second fixing mechanism 150 to the second fixed connection part 180 through the arrangement of multiple fixing parts 160. The light source device 100 can be firmly connected to the external structure through the first fixed connection part 170 and the second fixed connection part 180, thereby improving the stability and reliability of the entire device and reducing shaking and changes during use.

[0053] Please continue to see Figure 3 The first fixing mechanism 140 has an adjusting protrusion T on a first fixing outer side surface 171 close to the first fixing connection portion 170 , and the second fixing mechanism 150 has an adjusting protrusion T on a second fixing outer side surface 181 close to the second fixing connection portion 180 . The first fixing connection portion 170 and the second fixing connection portion 180 are provided with an arc groove H.

[0054] The adjusting protrusion T is accommodated in the arc groove H, and is configured to drive the fixing mechanism to move by moving in the arc groove H, so as to adjust the direction of the light angle r.

[0055] Optionally, the arc groove H is a through groove, and the adjusting protrusion T can pass through the arc groove H, and by changing the position of the adjusting protrusion T in the arc groove H, the direction of the light angle r of the light source device 100 can be adjusted.

[0056] Optionally, the arc groove H may not be set as a through groove, and the adjustment protrusion T is set in the arc groove H by snapping, and the light angle r direction of the light source device 100 is still adjusted by changing the position of the adjustment protrusion T in the arc groove H.

[0057] It should be understood that the above process introduces that the light source device 100 provided in the embodiment of the present application fixes the first fixing mechanism 140 to the first fixed connection part 170, and fixes the second fixing mechanism 150 to the second fixed connection part 180 through the fixing member 160; in the above process, the adjustment of the position of the light angle r through the arc groove H needs to be performed before the fixing member 160 fixes the first fixing mechanism 140 to the first fixed connection part 170, and fixes the second fixing mechanism 150 and the second fixed connection part 180, that is, to determine the optimal position of the light angle r in the target application scenario.

[0058] It can be seen from this that the light source device 100 provided in the embodiment of the present application is designed to adjust the direction of the light angle r of the light source device 100 by adjusting the movement of the protrusion T in the arc groove H, so that the light source device 100 has greater flexibility and adjustability, and can adapt to different shooting scenes and application requirements, thereby helping to improve the ease of use and efficiency of the light source device 100.

[0059] In an optional embodiment, the arc-shaped groove H includes a plurality of tooth-like positions, and the tooth-like positions are configured to accommodate the adjustment protrusion T to fix the fixing mechanism.

[0060] The tooth-like position includes a protruding portion and a recessed portion, and the tooth-like position can be distributed on the inner surface of the arc-shaped groove H to form a series of tooth-like structures. When the light angle r needs to be adjusted to a certain position by adjusting the adjusting protrusion T, the adjusting protrusion T can be stuck in the recessed portion of the tooth-like position.

[0061] It can be seen that the light source device 100 provided in the embodiment of the present application can fix the adjustment protrusion T by adding teeth, ensuring that the light angle r of the light source device 100 can be accurately adjusted and fixed, which helps to improve the convenience and operation efficiency of the light source device 100.

[0062] In an optional embodiment, the color of the light shielding surface 120 is a color that does not interfere with light.

[0063] That is to say, the color of the light shielding surface 120 is similar to or compatible with the color of the light emitted by the light source 130 and will not affect or interfere with the color of the light.

[0064] For example, the color of the shading surface 120 may be a neutral color, such as white or gray, or a color similar to the light emitted by the light source 130, to ensure that the existence of the shading surface 120 does not change the color temperature or spectral characteristics of the light. In this way, the absorption or reflection of the light color by the shading surface 120 can be minimized to maintain the color consistency and quality of the light.

[0065] It can be seen that the color of the shading surface 120 is selected to be a color that does not interfere with the illumination, which effectively prevents the shading surface 120 from interfering with or losing the light while maintaining the color consistency and quality of the light.

[0066] Please see Figure 4 , Figure 4 This is a structural schematic diagram of an image acquisition device 200 provided in an embodiment of the present application; the present application also provides an image acquisition device 200, which includes a box 210, a light-transmitting stage 220, a top camera 231, a bottom camera 232 and a light source device 100.

[0067] The top surface camera 231 is set on the top surface of the box 210 and faces the light-transmitting stage 220; the bottom surface camera 232 is set on the bottom surface of the box 210 and faces the light-transmitting stage 220; the top surface camera 231 is configured to obtain the top surface image of the target object on the light-transmitting stage 220, and the bottom surface camera is configured to obtain the bottom surface image of the target object on the light-transmitting stage 220.

[0068] like Figure 4 As shown, light source devices 100 are respectively arranged on the sides of the box 210 on both sides of the loading platform, and the light source devices 100 are configured to provide light for the target object.

[0069] It should be noted that the light source device 100 provided in the image acquisition device 200 is the light source device 100 mentioned above, and therefore, the structure and function of the light source device 100 included in the image acquisition device 200 will not be described in detail below.

[0070] Since the stage in the image acquisition device 200 is a light-transmitting stage 220, when acquiring the top surface image of the target object through the top surface camera 231, the light from the bottom surface may hit the top surface camera 231, interfering with the imaging of the top surface camera 231; when acquiring the bottom surface portrait of the target object through the bottom surface camera 232, the light from the top surface may hit the bottom surface camera 232, interfering with the imaging of the bottom surface camera 232.

[0071] Therefore, in order to solve the problem of side light interfering with the imaging of the camera on this side, the above-mentioned light source device 100 is arranged in the image acquisition device provided in the embodiment of the present application. The position and angle of the light source device 100 can be adjusted to ensure lighting while preventing its light from directly striking the camera lens, thereby reducing interference and ensuring the normal operation of the image acquisition device 200 and high-quality imaging effects.

[0072] In an optional embodiment, the fixed connection portion of the light source device 100 is fixedly connected to the side plate of the box body 210 by screws. Figure 4 As shown, light source devices 100 are disposed on the four sides of the box 210, four light source devices 100 are disposed above the transparent stage, and four light sources 130 are disposed below the transparent stage; Figure 4 The image acquisition device 200 in the embodiment is provided with a total of 8 light source devices 100 , but in practical applications, the number of the light source devices 100 can be appropriately increased or decreased.

[0073] The light source device 100 mentioned above comprises two fixing connection parts, namely a first fixing connection part 170 and a second fixing connection part 180 . The fixing connection parts of the light source device 100 are fixedly connected to the side plates of the box body 210 by screws.

[0074] In an optional embodiment, the light angle r formed by the light source surface 110 and the shading surface 120 is 90°, and the angle between the light source surface 110 and the horizontal plane is 45°; wherein the horizontal plane is a plane parallel to the top surface, the bottom surface and the plane where the stage is located.

[0075] That is to say, the light source surface 110 and the shading surface 120 of the light source device 100 in the above process are perpendicular to each other, forming a light angle r of 90°, and the angle between the light source surface 110 of each light source device 100 and the horizontal plane is 45°, thereby ensuring that the problem of the opposite side light interfering with the imaging of the camera on this side can be solved while ensuring the lighting required for imaging.

[0076] It should be noted that the light angle r of 90° and the included angle of 45° in the above process are not absolute values, and there may be angle deviations in actual operations; and the size of the light angle r and the included angle between the light source surface 110 and the horizontal plane are not necessarily 90° and 45°. In practical applications, adaptive adjustment of the angle is allowed for the purpose of improving the imaging effect.

[0077] like Figure 4 As shown, the horizontal plane is a plane parallel to the plane where the top surface, the bottom surface and the stage are located.

[0078] In an optional embodiment, the material of the light shielding surface 120 includes a transparent material. The light shielding surface 120 also includes a covering covering the transparent material, wherein the covering is used to block light from passing through the transparent material.

[0079] For example, the transparent material may be a transparent acrylic material or a transparent glass, etc. The covering of the light shielding surface 120 may be a material such as white adhesive paper pasted on the transparent material that can block part of the light from passing through the transparent material.

[0080] During the inspection of the shoes, an image acquisition device 200 provided in an embodiment of the present application can be used to acquire images of the shoes (including the shoe body, the insole, the shoe accessories, etc.). The light-transmitting stage 220 can ensure that the image of the bottom of the shoe can be acquired, and the light source device 100 arranged on both sides of the box can provide illumination for the shoes on the light-transmitting stage 220.

[0081] The light source surface 110 and the shading surface 120 of the light source device 100 are perpendicular to each other, forming a light angle r of 90°. The angle between the light source surface 110 of each light source device 100 and the horizontal plane is 45°, thereby ensuring that the shoes can be provided with the required lighting for shooting without affecting the acquisition of the shoe image by the opposite camera, thereby ensuring that the photo shooting process of the shoes is efficient and the captured pictures are of high quality, thereby improving the efficiency of shoe detection.
