Description

Technical Field

[0001] This utility model relates to the field of artificial intelligence matching technology for tree seed-type collectibles, and in particular to an image acquisition device. Background Technology

[0002] Currently, the raw materials for ornamental walnuts (including but not limited to hemp walnuts, iron walnuts, catalpa walnuts, lantern walnuts, etc.) require professional pairers to screen and match them after harvesting. However, matching thousands of ornamental walnuts is a very large workload, and the selection personnel are prone to visual fatigue and memory lapses, which ultimately leads to poor matching results.

[0003] Existing technology provides an image acquisition device that can place tree seed-type collectibles on a platform and perform rotational image acquisition via an image acquisition device surrounding the platform. However, natural tree seed-type collectibles vary in shape and size. If the collectibles roll or shake when placed directly on the platform, the acquisition position of each collectible will be different. Images acquired from different positions will have a significant impact on subsequent image analysis, resulting in low matching efficiency and accuracy between tree seed-type collectibles. Utility Model Content

[0004] This utility model provides an image acquisition device to solve the defects of existing acquisition platforms. It can fix the position of tree seed-type cultural artifacts through the first clamping component and the second clamping component, thereby ensuring the accuracy and stability of the images acquired by the image acquisition device. It can effectively avoid the difference in acquisition position caused by the inconsistency of tree seed-type cultural artifacts in shape and size, and thus effectively improve the matching efficiency and accuracy of subsequent tree seed-type cultural artifacts.

[0005] The image acquisition device provided by this utility model includes a first clamping component, a second clamping component, and at least one acquisition component. The first clamping component and the second clamping component are arranged opposite to each other, and one of the first clamping component and the second clamping component can extend and retract relative to the other. The first clamping component and the second clamping component are used to clamp the object to be acquired. The acquisition component is used to acquire image information of the object to be acquired.

[0006] According to the image acquisition device provided by this utility model, the first clamping component includes a first clamping rod, the first clamping rod is disposed opposite to the second clamping component, and the first clamping rod can extend and retract relative to the second clamping component;

[0007] And / or, the second clamping assembly includes a second clamping rod, which is disposed opposite to the first clamping assembly and is telescopically movable relative to the first clamping assembly.

[0008] According to the image acquisition device provided by this utility model, the first clamping component includes a first elastic member, the first elastic member is disposed opposite to the second clamping component, and the first elastic member can elastically extend and retract relative to the second clamping component.

[0009] And / or, the second clamping assembly includes a second elastic member, which is disposed opposite to the first clamping assembly, and the second elastic member can elastically extend and retract relative to the first elastic member.

[0010] According to the image acquisition device provided by this utility model, at least one of the first clamping assembly and the second clamping assembly is provided with a rotating member, which is used to drive the object to be acquired to rotate.

[0011] When both the first clamping assembly and the second clamping assembly are provided with the rotating member, the rotating member of the first clamping assembly and the rotating member of the second clamping assembly rotate in the same direction and at the same speed.

[0012] According to the image acquisition device provided by this utility model, at least one of the first clamping component and the second clamping component is provided with an abutment portion, the shape of which matches the shape of the object to be acquired.

[0013] According to the image acquisition device provided by this utility model, the abutment part includes a conical head, which is used to extend into the recess of the object to be acquired, so as to restrict the radial movement of the object to be acquired.

[0014] According to the image acquisition device provided by this utility model, the abutting part includes an arc-shaped surface, which is used to wrap the protrusion of the object to be acquired, so as to restrict the radial movement of the object to be acquired.

[0015] According to the image acquisition device provided by this utility model, at least one of the first clamping component and the second clamping component is provided with the detachable abutment portion.

[0016] The image acquisition device provided by this utility model further includes a housing, wherein the first clamping component is disposed on the top wall of the housing, and the second clamping component is disposed on the bottom wall of the housing; or, the first clamping component and the second clamping component are disposed opposite to each other on a pair of side walls of the housing.

[0017] The acquisition components are provided in multiple ways, and the multiple acquisition components are respectively located at corresponding positions of the housing, the first clamping component and the second clamping component. The housing is used to filter out external stray light.

[0018] The image acquisition device provided by this utility model also includes a soft light illumination element, which is disposed at the corner of the side wall of the housing and is used to supplement the light for the acquisition component.

[0019] In the image acquisition device provided by this utility model, by setting a first clamping component and a second clamping component arranged opposite to each other, when the image acquisition device performs image acquisition on the object to be acquired, the first clamping component and the second clamping component can respectively suspend and fix the object to be acquired from both ends of the object to be acquired. Taking a walnut as an example, when the image acquisition device performs image acquisition on a walnut, it can first press one of the retractable and movable first clamping components and the second clamping component, then place the walnut to be detected between the first clamping component and the second clamping component, and straighten the position of the walnut. Then, release the press on the first clamping component or the second clamping component. In this way, the walnut can be fixed between the first clamping component and the second clamping component in the correct position and posture. This can effectively improve the accuracy and acquisition effect of the acquisition component in acquiring the image of the object to be acquired.

[0031] Figure 1 This is a cross-sectional structural diagram of the image acquisition device provided in this embodiment of the present invention from the main viewing angle; Figure 2 This is an isometric view of the image acquisition device provided in an embodiment of the present invention.

[0032] See Figure 1 and Figure 2 This utility model embodiment provides an image acquisition device for acquiring image information of the object to be acquired 400 from all directions. This utility model embodiment takes the image acquisition device for acquiring images of tree seed-type collectibles as an example, specifically taking walnuts, a type of tree seed collectible, as an example for illustration.

[0033] The image acquisition device includes a first clamping component 100, a second clamping component 200, and at least one acquisition component 300. The first clamping component 100 and the second clamping component 200 are arranged opposite to each other, and a clamping sampling area is defined between them. One of the first clamping component 100 and the second clamping component 200 can be extended and retracted relative to the other. Specifically, the first clamping component 100 can be extended and retracted relative to the second clamping component 200, or the second clamping component 200 can be extended and retracted relative to the first clamping component 100. In some optional embodiments of this utility model, both the first clamping component 100 and the second clamping component 200 can also have the function of extension and retraction.

[0034] The acquisition component 300 can be set to one or multiple, and can be adapted to the specific situation. The acquisition component 300 is used to acquire image information of the object to be acquired 400. It should be noted that the image information can be either pictures or videos, and new choices can be made according to the specific situation. The acquisition component 300 can be selected from existing components such as cameras, video cameras, and image acquisition devices.

[0035] See Figure 1 and Figure 2It is understood that in the image acquisition device provided in this embodiment of the present invention, by setting up a first clamping component 100 and a second clamping component 200 that are arranged opposite to each other, when the image acquisition device performs image acquisition on the object to be acquired 400, the first clamping component 100 and the second clamping component 200 can respectively suspend and fix the object to be acquired 400 from both ends of the object to be acquired. Taking a walnut as an example, when the image acquisition device performs image acquisition on the walnut, it can first press one of the retractable components of the first clamping component 100 and the second clamping component 200, then place the walnut to be detected between the first clamping component 100 and the second clamping component 200, and straighten the position of the walnut. Then, release the pressing on the first clamping component 100 or the second clamping component 200. In this way, the walnut can be fixed between the first clamping component 100 and the second clamping component 200 in the correct position and posture. This can effectively improve the accuracy and acquisition effect of the acquisition component 300 in acquiring the image of the object to be acquired 400.

[0036] Compared to existing technologies, the image acquisition device provided in this embodiment of the present invention can fix the position of tree seed-type collectibles through the first clamping component 100 and the second clamping component 200, thereby ensuring the accuracy and stability of the images acquired by the image acquisition device. This can effectively avoid the difference in acquisition position caused by the inconsistent shape and size of tree seed-type collectibles, reduce the impact of different shooting positions on image analysis, reduce the difficulty of correction in the post-processing of images, and thus effectively improve the matching efficiency and accuracy of subsequent tree seed-type collectibles.

[0037] Continue reading Figure 1 and Figure 2 In an optional embodiment of the present invention, the first clamping assembly 100 includes a first clamping rod 110, which is disposed opposite to the second clamping assembly 200, and the first clamping rod 110 can telescopically move relative to the second clamping assembly 200. Specifically, a telescopic spring connected to the first clamping rod 110 can be provided inside the first clamping assembly 100, and the telescopic movement of the first clamping rod 110 can be achieved by the deformation characteristics of the telescopic spring. In an optional embodiment of the present invention, a threaded connection can also be used, for example, a threaded hole is provided in the first clamping assembly 100, and a corresponding thread is provided on the first clamping rod 110, so that the telescopic movement of the first clamping rod 110 relative to the second clamping assembly 200 can be achieved by rotating the thread.

[0038] It is understandable that the first clamping rod 110 is a rod, which can effectively reduce the contact area when it comes into contact with the object to be acquired 400, thereby reducing the obstruction of the object to be acquired 400 by the first clamping rod 110. Secondly, since the first clamping member is a rod, the first clamping rod 110 can effectively reduce the obstruction of the field of view of the acquisition component 300, thereby improving the efficiency and quality of image acquisition by the acquisition component 300. In summary, the first clamping rod 110 can not only effectively fix the acquisition position of the object to be acquired 400, but also effectively reduce its impact on the acquisition image of the acquisition component 300 as a limiting member.

[0039] Continue reading Figure 1 and Figure 2 In an optional embodiment of the present invention, the second clamping assembly 200 includes a second clamping rod 120, which is disposed opposite to the first clamping assembly 100 and can telescopically move relative to the first clamping assembly 100. Specifically, a telescopic spring connected to the second clamping rod 120 can be provided inside the second clamping assembly 200, and the telescopic movement of the second clamping rod 120 can be achieved by the deformation characteristics of the telescopic spring. In an optional embodiment of the present invention, a threaded connection can also be used, for example, a threaded hole is provided in the second clamping assembly 200, and a corresponding thread is provided on the second clamping rod 120, so that the telescopic movement of the second clamping rod 120 relative to the first clamping assembly 100 can be achieved by rotating the thread.

[0040] It is understandable that the second clamping rod 120, being a rod, effectively reduces the contact area when it abuts against the object to be acquired 400, thus reducing the obstruction of the object to be acquired 400 by the second clamping rod 120. Secondly, since the second clamping rod is a rod, it effectively reduces the obstruction of the acquisition field of view of the acquisition component 300, thereby improving the efficiency and quality of image acquisition by the acquisition component 300. In summary, the second clamping rod 120 not only effectively fixes the acquisition position of the object to be acquired 400, but also effectively reduces its impact on the acquisition image of the acquisition component 300 as a limiting component. It should be noted that the second clamping rod 120 provided in this embodiment can be set simultaneously with the first clamping rod 110 in the aforementioned embodiment, which can effectively improve the efficiency of replacing the object to be acquired 400 and reduce the difficulty of replacement.

[0041] In an optional embodiment of this utility model, unlike the aforementioned embodiments, the first clamping component 100 includes a first elastic element, which is disposed opposite to the second clamping component 200, and the first elastic element can elastically extend and retract relative to the second clamping component 200. Specifically, the first elastic element can be a spring-like device, or a component made of materials such as rubber, thermoplastic elastomer, or highly elastic fiber material. These materials have good elasticity and can change their shape when compressed. When used in the first elastic element, they can give the first elastic element good elasticity and extensibility.

[0042] It is understandable that when installing the object to be collected 400, the first elastic element can be pressed away from the second clamping component 200, and then the object to be collected 400 can be placed between the first elastic element and the second clamping component 200. The posture and position of the object to be collected 400 can be adjusted, and then the pressing on the first elastic element can be withdrawn. The first elastic element has the characteristic of elastic extension and contraction. When it comes into contact with the object to be collected 400, it can firmly press the object to be collected onto the second clamping component 200, thereby ensuring its stability and safety. It is also understandable that the contact between the first elastic element and the object to be collected 400 is elastic. This can avoid damage to the object to be collected 400 caused by hard contact. For relatively precious items such as walnuts, this can effectively ensure the safety of the object to be collected 400.

[0043] In an optional embodiment of this utility model, unlike the aforementioned embodiments, the second clamping component 200 includes a second elastic element. The second elastic element is disposed opposite to the first clamping component 100, and the second elastic element can elastically extend and retract relative to the first clamping component 100. Specifically, the second elastic element can be a spring-like device, or a component made of materials such as rubber, thermoplastic elastomer, or highly elastic fiber material. These materials have good elasticity and can change their shape when compressed. When used in the second elastic element, they can make the second elastic element have good elastic extensibility.

[0044] It is understandable that when installing the sample 400, the second elastic element can be pressed down in a direction away from the first clamping assembly 100, and then the sample 400 can be placed between the second elastic element and the first clamping assembly 100. The posture of the sample 400 can be adjusted, and then the pressure on the second elastic element can be withdrawn. The second elastic element has elastic expansion and contraction characteristics. When it comes into contact with the sample 400, it can firmly press the sample onto the first clamping assembly 100, thereby ensuring its stability and safety. It is also understandable that the contact between the second elastic element and the sample 400 is elastic, which can avoid damage to the sample 400 caused by hard contact. This can effectively ensure the safety of relatively precious items such as walnuts. It should be noted that the second elastic element provided in this embodiment can be set simultaneously with the first elastic element in the aforementioned embodiment, which can effectively improve the efficiency of replacing the sample 400 and reduce the difficulty of replacement.

[0045] Continue reading Figure 1 and Figure 2 In an optional embodiment of this utility model, the first clamping assembly 100 further includes a rotating member 500. When the first clamping assembly 100 includes a first clamping rod 110, the rotating member 500 is located at the end of the first clamping rod 110 away from the second clamping assembly 200. The rotating member 500 is used to drive the first clamping rod 110 to rotate, thereby driving the sample to be collected 400 to rotate. In this case, whether the second clamping assembly 200 includes a second clamping rod 120 or a second elastic member, it needs to have a driven function, that is, the second clamping assembly 200 needs to rotate with the first rotating rod.

[0046] When the first clamping assembly 100 includes the first elastic member, the rotating member 500 is located at the end of the first clamping member away from the second clamping assembly 200. The rotating member 500 is used to drive the first elastic member to rotate, thereby driving the sample 400 to be collected to rotate. In this case, whether the second clamping assembly 200 includes the second clamping rod 120 or the second elastic member, it needs to have a driven function, that is, the second clamping assembly 200 needs to rotate with the first elastic member.

[0047] It is understood that in the image acquisition device provided in this embodiment of the present invention, by setting a rotating member 500, the member to be acquired 400 can be rotated by the rotating member 500, so that the acquisition component 300 can acquire image information of the member to be acquired 400 from different angles, thus making the image information of the member to be acquired 400 more comprehensive and detailed; secondly, this can reduce the number of acquisition components 300, reduce the difficulty of the deployment of acquisition components 300, facilitate the miniaturization of the image acquisition device, and effectively reduce the manufacturing cost of the image acquisition device.

[0048] Continue reading Figure 1 and Figure 2 In an optional embodiment of this utility model, the second clamping assembly 200 further includes a rotating member 500. When the second clamping assembly 200 includes a second clamping rod 120, the rotating member 500 is located at the end of the second clamping rod 120 away from the first clamping assembly 100. The rotating member 500 is used to drive the second clamping rod 120 to rotate, thereby driving the sample to be collected 400 to rotate. In this case, whether the first clamping assembly 100 includes the first clamping rod 110 or the first elastic member, it needs to have a driven function, that is, the first clamping assembly 100 needs to rotate with the second rotating rod.

[0049] When the second clamping assembly 200 includes the second elastic member, the rotating member 500 is located at the end of the second clamping member away from the first clamping assembly 100. The rotating member 500 is used to drive the second elastic member to rotate, thereby driving the sample to be collected 400 to rotate. In this case, whether the first clamping assembly 100 includes the first clamping rod 110 or the first elastic member, it needs to have a driven function, that is, the first clamping assembly 100 needs to rotate with the second elastic member.

[0050] It is understood that in the image acquisition device provided in this embodiment of the present invention, by setting a rotating member 500, the member to be acquired 400 can be rotated by the rotating member 500, so that the acquisition component 300 can acquire image information of the member to be acquired 400 from different angles, thus making the image information of the member to be acquired 400 more comprehensive and detailed; secondly, this can reduce the number of acquisition components 300, reduce the difficulty of the deployment of acquisition components 300, facilitate the miniaturization of the image acquisition device, and effectively reduce the manufacturing cost of the image acquisition device.

[0051] Continue reading Figure 1 and Figure 2 In an optional embodiment of this utility model, the first clamping component 100 is provided with a rotating member 500, and the second clamping component 200 is also provided with a rotating member 500. The specific configuration of the rotating member 500 can be referred to the foregoing embodiment. In this embodiment of the utility model, that is, when both the first clamping component 100 and the second clamping component 200 are provided with rotating members 500, the rotating members 500 of the first clamping component 100 and the second clamping component 200 need to rotate in the same direction and at the same speed.

[0052] Understandably, the design of rotating in the same direction and at the same speed ensures the stability and smoothness of the sample 400 during rotation, and can avoid damage to the sample 400 caused by inconsistent rotation speed or direction of rotation of the rotating parts 500 of the first clamping component 100 and the second clamping component 200; secondly, the rotating parts 500 of both the first clamping component 100 and the second clamping component 200 can effectively distribute the load of the sample 400, making the force on both ends of the sample 400 more balanced, and improving the safety of the sample 400.

[0053] In an optional embodiment of this utility model, the first clamping component 100 is provided with an abutment portion. When the first clamping component 100 is provided with a first clamping rod 110, the abutment portion is provided at one end of the first clamping rod 110 facing the second clamping component 200. When the first clamping component 100 is provided with a first elastic member, the abutment portion is provided at one end of the first elastic member facing the second clamping component 200. The shape of the abutment portion matches the shape of the object to be collected 400. Taking a walnut as an example, there is usually a depression at the root-stem connection of a walnut. By providing a protrusion that can extend into the depression, when the walnut abuts with the abutment portion, the first clamping component 100 can effectively restrict the radial movement of the walnut.

[0054] In an optional embodiment of this utility model, the second clamping component 200 is provided with an abutment portion. When the second clamping component 200 is provided with a second clamping rod 120, the abutment portion is located at one end of the second clamping rod 120 facing the first clamping component 100. When the second clamping component 200 is provided with a second elastic member, the abutment portion is located at one end of the second elastic member facing the first clamping component 100. The shape of the abutment portion matches the shape of the object to be collected 400. Taking a walnut as an example, there is usually a depression at the root-stem connection of a walnut. By providing a protrusion that can extend into the depression, when the walnut abuts with the abutment portion, the second clamping component 200 can effectively restrict the radial movement of the walnut.

[0055] In an optional embodiment of this utility model, both the first clamping component 100 and the second clamping component 200 can be provided with abutment portions. In this case, the abutment portions of the first clamping component 100 and the second clamping component 200 can be matched with the shapes of the two ends of the object to be acquired 400. The setting of the abutment portions can be referred to the above description, and will not be repeated here. It is understood that compared with the general planar clamping method, the abutment portion whose shape matches the object to be acquired 400 can better fit the surface of the object to be acquired 400, reduce stress concentration points during the clamping process, and thus reduce the risk of deformation or damage to the object to be acquired 400 under the action of clamping force. Secondly, for the object to be acquired 400 with irregular shape or complex surface, such as a walnut, the tight fit of the abutment portion can effectively prevent the walnut from translating, rotating or shaking during the image acquisition process, which is crucial for obtaining clear and accurate images.

[0056] In an optional embodiment of this utility model, the abutment part includes a conical head, which is used to extend into the recess of the object to be collected 400 to restrict the radial movement of the object to be collected 400. Taking a walnut as an example, it can be understood that a conical recess is naturally formed at the root of the walnut, and the surface where this recess is located is usually considered to be the bottom surface of the walnut. In this embodiment of the utility model, when the image acquisition device is used to collect walnuts, the conical head can extend into the recess at the bottom of the walnut. Compared with the traditional planar placement method, this method can provide more accurate and stable radial positioning, which can fundamentally restrict the movement of the walnut and ensure that the acquired image will not be blurred, deformed or ghosted due to the rolling or shaking of the walnut.

[0057] In addition, since the conical head fits the concave part at the bottom of the walnut, staff can easily help the walnuts find the correct posture when placing them, thus ensuring the accuracy and stability of the images captured by the image acquisition device. This effectively avoids differences in the acquisition position caused by the shape and size of the walnuts, reduces the impact of different shooting positions on image analysis, and thus effectively improves the efficiency and accuracy of subsequent walnut pairing.

[0058] In an optional embodiment of this utility model, the abutment portion includes an arc-shaped surface, which is used to wrap around the protrusion of the object to be collected 400, so as to restrict the radial movement of the object to be collected 400. Taking a walnut as an example, it can be understood that the shape of a walnut is generally similar to a sphere. In some other examples, walnuts also have some pointed bottoms. All positions of the sphere and the aforementioned pointed bottoms can be understood as protruding structures. In this embodiment of the utility model, when the image acquisition device is used to collect walnuts, the arc-shaped surface can wrap around the protruding structure on the top of the walnut. Compared with the traditional planar placement method, this method can provide more accurate and stable radial positioning, which can fundamentally restrict the movement of the walnut and ensure that the acquired image will not be blurred, deformed or ghosted due to the rolling or shaking of the walnut.

[0059] In addition, since the curved surface matches the protrusion on the top of the ornamental walnut, staff can easily help the walnut find the correct posture when placing it, thus ensuring the accuracy and stability of the images captured by the image acquisition device. This effectively avoids differences in the acquisition position caused by the inconsistent shape and size of the ornamental walnuts, reduces the impact of different shooting positions on image analysis, and thus effectively improves the efficiency and accuracy of subsequent pairing of ornamental walnuts.

[0060] In an optional embodiment of this utility model, the abutment portion can be made of flexible silicone or rubber. Flexible silicone has good flexibility and resilience, while rubber has a certain degree of elasticity and wear resistance. Both can effectively prevent rigid collisions or scratches during contact with the sample 400. Simultaneously, the flexible silicone or rubber portion at the head can be specially designed and customized according to the actual shape of the sample 400, shaping it into a specific shape that precisely matches it. This not only significantly increases the fixation effect on the sample 400, making it more stable and reliable during operation and less prone to displacement or shaking, but also minimizes damage to the sample 400 caused by contact, such as scratches, indentations, or wear, thereby effectively protecting the integrity and surface quality of the sample 400.

[0061] In an optional embodiment of the present invention, at least one of the first clamping assembly 100 and the second clamping assembly 200 is provided with a detachable abutment portion. In other words, the abutment portion is a detachable structure. Since the abutment portion is provided at the ends of the first clamping rod 110, the second clamping rod 120, the first elastic member and the second elastic member, the first clamping rod 110, the second clamping rod 120, the first elastic member and the second elastic member can be set as detachable components.

[0062] Taking walnuts for collecting and playing with as an example, it is understandable that this design facilitates the replacement and disassembly of walnuts. On the other hand, when encountering walnuts with special shapes, the abutment part that matches the shape of the walnut can be replaced. The same applies to other types of tree seed collectibles. When the image acquisition device is used to acquire images of other types of tree seed collectibles, the abutment part that matches the shape of the tree seed collectible can be replaced. This can improve the versatility and reliability of the image acquisition device.

[0063] Continue reading Figure 1 and Figure 2 In an optional embodiment of this information, the image acquisition device further includes a housing 600, with a first clamping component 100 disposed on the top wall of the housing 600 and a second clamping component 200 disposed on the bottom wall of the housing 600, i.e., vertically arranged; or, the first clamping component 100 and the second clamping component 200 may be disposed opposite each other on a pair of side walls of the housing 600, i.e., horizontally arranged; multiple acquisition components 300 are provided, the illustration shows the case of three acquisition components 300, wherein the first acquisition component 300 is disposed on the side wall of the housing 600, the second... The acquisition component 300 is located on the first clamping component 100, and the third acquisition component 300 is located on the second clamping component 200. The acquisition component 300 can be a camera device with a variable angle. The acquisition angle of the acquisition component 300 can be adaptively set according to the actual acquisition needs. For example, the acquisition angle of the acquisition component 300 on the side wall of the housing 600 can be perpendicular to the side of the object to be acquired 400, and the acquisition angle of the acquisition component 300 on the first clamping component 100 and the second clamping component 200 can be aligned with the center of the upper and lower surfaces of the object to be acquired 400.

[0064] Understandably, the housing 600 serves two purposes: firstly, it provides support for the first clamping component 100 and the second clamping component 200; secondly, during image acquisition, the housing 600 isolates external light, preventing stray light from affecting the image acquisition process of the acquisition component 300, thus improving the clarity and accuracy of the image information acquired by the image acquisition component 300. Furthermore, the light-shielding design of the housing 600 provides a stable external environment for image acquisition, ensuring the consistency and reliability of image acquisition.

[0065] Figure 3 This is a schematic cross-sectional view of the image acquisition device provided in this embodiment of the present invention from a top-down perspective.

[0066] See Figure 1 and Figure 3The image acquisition device also includes a soft light illuminator 700, which is located at the included angle of the side wall of the housing 600. The soft light illuminator 700 is used to provide supplementary lighting for the image acquisition process of the acquisition component 300. It is understood that by positioning the soft light illuminator 700 at the included angle of the side wall of the housing 600, it is ensured that the soft light illuminator 700 does not appear within the field of view of the acquisition component 300. This not only ensures the lighting conditions during image acquisition but also improves the accuracy of the acquired image information. In an optional embodiment of this invention, the soft light illuminator 700 can be a combination of an LED light strip and a diffuser. This structure is low-cost and simple, effectively reducing the manufacturing cost of the image acquisition device.

[0067] See Figure 1 and Figure 2 In an optional embodiment of this utility model, a control component 800 can also be provided on the outside of the housing 600. The control component 800 can control the operation of the first clamping component 100, the second clamping component 200, the acquisition component 300 and the soft light illumination component 700 inside the housing 600. Specifically, the control component 800 can be adapted to the actual situation, for example, by setting control buttons or control panels.
