Description

Technical Field

[0001] This application belongs to the field of scanning equipment, and more specifically, relates to a scanning component and a scanning device having the scanning component. Background Technology

[0002] With the development of technology, 3D-related technologies are increasingly being applied in various industries, such as 3D modeling and 3D printing. In the medical aesthetics industry, such as plastic surgery, 3D-related technologies are also being widely used. For example, before and after treatment (or surgery), the patient is scanned and modeled for archiving. Especially when scanning the human head, the accuracy of the scanning equipment is required to achieve the desired facial details during modeling.

[0003] Existing scanning equipment generally includes two steps: scanning modeling and texture mapping. When acquiring the surface texture of the scanned object, a supplementary light (or other lighting device) is usually used to illuminate the object, especially when scanning the head. Sufficiently bright and uniform ambient light or supplementary light is needed to obtain good texture details. Existing supplementary lights typically achieve illumination by projecting monochromatic light or monochromatic light images onto the scanned object. However, during this process, when the imaging module captures the surface of the scanned object to obtain texture information, the monochromatic light or monochromatic light image projected by the supplementary light can easily form pixel grids (i.e., gaps between pixels) in the imaging module's view. This pixel grid becomes more noticeable, especially when the image is magnified, resulting in poor image quality and affecting the clarity of the texture map. This, in turn, impacts the analysis of high-standard medical data such as archival records and skin analysis. Summary of the Invention

[0004] The purpose of this application is to provide a scanning component and a scanning device having the scanning component, so as to solve the technical problem that the fill light in the prior art is prone to forming pixel grids in the captured image.

[0005] To achieve the above objectives, the technical solution adopted in the embodiments of this application is as follows:

[0006] On one hand, a scanning component is provided, including a scanner for scanning an object and acquiring data, a shooting module for taking a picture of the object, a filler for emitting a monochromatic light image to the object during the taking of a picture, and a filtering component for covering the front of the filler to eliminate the pixel grid of the monochromatic light image.

[0007] Optionally, the filter assembly includes a filter sheet having a planar side and a curved side disposed opposite to each other. The planar side is close to the front of the filler, and the curved side includes a concave lens portion and a convex lens portion for scattering and amplifying the light from the filler, the convex lens portion and the concave lens portion being disposed adjacent to each other.

[0008] Optionally, one, two, or more convex mirror portions and concave mirror portions are provided respectively, and the convex mirror portions and concave mirror portions are arranged alternately along the curved surface side.

[0009] Optionally, the convex lens portion and the concave lens portion have the same radius of curvature, and the radius of curvature of the convex lens portion and the concave lens portion is 2mm to 4mm.

[0010] Optionally, the distance from the filter to the front of the fill light is 5mm to 10mm, the distance from the filter to the scanned object is 500mm to 1000mm, and / or the distance from the filter to the scanned object is 80 to 100 times the distance from the filter to the fill light.

[0011] Optionally, the filter assembly further includes a drive member for driving the filter sheet closer to or away from the front of the filler, the filter sheet being connected to the drive member.

[0012] Optionally, the scanning assembly further includes a mounting structure for aligning the centers of the fill light, the imaging module, and the scanner in a straight line. The mounting structure includes a mounting plate, with the fill light, the imaging module, and the scanner all located on one side of the mounting plate.

[0013] Optionally, the mounting structure includes an emitter pad for mounting the fill light, a scanner pad for mounting the scanner, and a filter mounting plate for mounting the filter assembly. One side of the scanner pad is connected to the mounting plate, and the other side of the scanner pad is connected to the scanner. One side of the emitter pad is connected to the mounting plate, and the other side of the emitter pad is connected to the fill light. Two emitter pads are arranged opposite each other, and the filter assembly is located between the two emitter pads and connected to the filter mounting plate.

[0014] Optionally, the fill light is a structured light emitter, which emits a striped grating when the scanner scans and emits the monochromatic light image when the imaging module takes a picture.

[0015] The beneficial effects of the scanning component provided in this application embodiment are as follows: Compared with the prior art, the scanning component provided in this application embodiment obtains the data information of the scanned object by scanning with a scanner, and uses a fill light to provide supplementary lighting when the shooting module takes a picture of the scanned object, so as to obtain image texture information with uniform light. At the same time, when the fill light projects a monochromatic light image, the pixel grid in the monochromatic light image is filtered out by a filter component covering the front of the fill light. This allows the monochromatic light image to provide supplementary lighting to the surface of the scanned object while eliminating the pixel grid in the picture captured by the shooting module, effectively improving the quality of the texture information obtained by the shooting module, making the texture map clearer, which is beneficial for high-standard archival records and the analysis of medical data such as skin analysis.

[0017] The beneficial effects of the scanning device provided in this application embodiment are as follows: Compared with the prior art, the scanning device provided in this application embodiment can effectively improve the three-dimensional modeling effect by collecting three-dimensional data and surface texture information of the scanned object through the above-mentioned scanning components, which is conducive to high-standard archival records and analysis of medical data such as skin analysis.

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0044] It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0045] The various specific technical features and embodiments described in the detailed implementation can be combined in any suitable manner without contradiction. For example, different implementation methods can be formed by combining different specific technical features / implementations / implementation methods. In order to avoid unnecessary repetition, the various possible combinations of the various specific technical features / implementations / implementation methods in this application will not be described separately.

[0046] Please refer to this as well. Figure 1 and Figure 2This application provides a scanning component 2, which can be applied to various scanning devices, especially in the medical aesthetics field for scanning and document creation, skin analysis, etc. The scanning component 2 includes a scanner 23, an imaging module 22, a fill light 211, and a filter component 25. In use, the scanner 23 scans the object and collects data, which is then used to create a 3D model. The imaging module 22 captures images of the object, obtaining its surface texture information and restoring it to the surface of the 3D model, thus establishing a complete 3D model. During the imaging process, the fill light 211 emits a monochromatic light image from the front of the object, improving the lighting and shadow effects, increasing the brightness and uniformity of the image captured by the imaging module 22, and making the collected texture information clearer and more accurate. Meanwhile, the filter component 25 can cover the front of the fill light 211 when the fill light 211 projects a monochromatic light image onto the surface of the scanned object, thereby eliminating the pixel grid of the monochromatic light image projected by the fill light 211 onto the surface of the scanned object, and thus eliminating the pixel grid in the image captured by the shooting module 22, further optimizing the image quality captured by the shooting module 22, and improving the clarity and fidelity of the texture map.

[0047] As one optional implementation of this embodiment, the fill light 211 can be a structured light emitter 21. The structured light emitter 21 emits a striped grating during scanning by the scanner 23. The striped grating can be projected onto the surface of the scanned object. Since the surface of the scanned object generally has some irregular depressions and protrusions, after the striped grating illuminates these areas, the striped grating will bend and deform to varying degrees at the depressions and protrusions. This allows the scanner 23 to obtain accurate 3D data based on the different degrees of deformation of the striped grating when scanning and acquiring data, which is beneficial to the accuracy of subsequent modeling. Simultaneously, the striped grating can, to a certain extent, enhance the highlight and shadow areas of the scanned object's surface, making the information acquired by the scanner 23 more accurate and further optimizing the scanning effect. At the same time, the structured light emitter 21 can emit monochromatic light images during image capture by the imaging module 22, improving the brightness and uniformity of the captured image, enabling the imaging module 22 to acquire high-definition and uniformly bright texture information. This design uses structured light emitter 21 to emit different types of images to help scanner 23 and imaging module 22 acquire high-quality scanning and texture data. Furthermore, during multi-angle and multi-dimensional scanning and imaging, the entire scanning component 2 can be moved directly without the need for readjustment. It features small footprint, ease of use, and high precision.

[0048] In a specific application, the structured light emitter 21 can magnify and project the input image onto the surface of the scanned object. During the projection process, due to the pixel limitation of the structured light emitter 21, the projected image will have a relatively obvious pixel grid, resulting in a relatively obvious pixel grid in the monochromatic light image projected onto the surface of the scanned object. The filtering component 25 of this embodiment can effectively blur and eliminate these pixel grids, resulting in higher clarity of the image captured by the imaging component.

[0049] For example, the striped grating emitted by the structured light emitter 21 can be horizontal stripes, vertical stripes, or diagonal stripes, or it can emit multiple striped gratings of different types. The scanner 23 acquires data under different striped gratings multiple times to further improve the scanning effect. In addition, the wavelength of the light emitted by the striped grating can be visible light or invisible light, and its specific wavelength can be selected according to the parameters of the scanner 23. This embodiment does not impose any limitations.

[0050] For example, the monochromatic light image emitted by the structured light emitter 21 can be visible light or invisible light, which can be selected according to the shooting module 22 used. The brightness and color temperature values ​​of the monochromatic light image can be selected and set according to factors such as the skin color of the subject being photographed and the ambient light of the current scene.

[0051] As one of the optional implementation methods in this embodiment, please also refer to... Figure 3 and Figure 6 The filter assembly 25 includes a filter 253, which has a planar side and a curved side disposed opposite to each other. The planar side is close to the front of the supplementary light source 211 (i.e., the side from which the supplementary light source 211 emits light), and the curved side is away from the front of the supplementary light source 211 (i.e., the curved side is close to the scanned object). The curved side includes a concave mirror portion 253b and a convex mirror portion 253a. The convex mirror portion 253a can protrude from the surface of the filter 253, and the concave mirror portion 253b can be recessed into the interior of the filter 253. The concave mirror portion 253b and the convex mirror portion 253a can scatter and amplify the light emitted by the supplementary light source 211. The convex mirror portion 253a and the concave mirror portion 253b can be disposed adjacent to each other. With this design, the light from the fill light 211 can enter the filter 253 from the flat side and exit from the curved side. When the light exits from the curved side, it is scattered and refracted to different degrees by the convex lens 253a and the concave lens 253b. The emitted light rays will cross and affect each other, which will magnify and blur the pixel grid between the pixels. As a result, the image after illuminating the surface of the scanned object will no longer have a pixel grid, thus improving the clarity and fidelity of the image captured by the shooting module 22.

[0052] For example, please continue to refer to Figure 6When the fill light 211 is an RGB three-primary-color structured light emitter 21, there will inevitably be certain gaps (i.e., pixel grids) between the R, G, and B color pixels of the structured light emitter 21. After the three light rays pass through the filter 253, the convex lens portion 253a and the concave lens portion 253b of the filter 253 can scatter and refract the three light rays, causing the light rays to interact with each other, amplifying and blurring the pixel grids between the light rays, thereby achieving the effect of eliminating pixel grids. Of course, in other embodiments, the fill light 211 can also be other fill light devices, or it can be other types of structured light emitters 21; this embodiment is not limited to these.

[0053] Specifically, as one of the optional implementation methods in this embodiment, please continue to refer to... Figure 6 The convex lens portion 253a and the concave lens portion 253b can each be provided with one, two, or more, and the convex lens portion 253a and the concave lens portion 253b can be arranged alternately along the curved surface to form a "wave" shaped structure. This design allows light to be scattered and refracted more regularly, enabling the pixel grid of the monochromatic light image to be eliminated more thoroughly, further improving the image quality captured by the shooting module 22. In specific applications, the specific number of concave lens portions 253b and convex lens portions 253a can be selected and set according to the size of the fill light 211, and this embodiment is not limited thereto.

[0054] For example, five convex lens portions 253a and three concave lens portions 253b may be provided, with the concave lens portions 253b and convex lens portions 253a being arranged alternately. The convex lens portions 253a may form strip-shaped protrusions on the curved side of the filter sheet 253, and the concave lens portions 253b may form strip-shaped depressions on the curved side.

[0055] Specifically, as one of the optional implementation methods in this embodiment, please continue to refer to... Figure 6 The two opposite ends of the curved side can be convex mirror portions 253a. Of course, in other embodiments, the two opposite ends of the curved side can also be concave mirror portions 253b, or they can be flat (the curved side near the edge is flat).

[0056] Specifically, as one of the optional implementation methods in this embodiment, please continue to refer to... Figure 6 The radii of curvature of the convex lens portion 253a and the concave lens portion 253b can be the same, that is... Figure 6In this design, R1 can be the same as R2, and the transition between the concave lens portion 253b and the convex lens portion 253a can be smooth. This design allows for more regular and controllable scattering and refraction of light, which is beneficial for further eliminating pixel grids and improving shooting results. Of course, in other embodiments, the radii of curvature of each convex lens portion 253a can be the same, the radii of curvature of each concave lens portion 253b can also be the same, and the radii of curvature between the convex lens portion 253a and the concave lens portion 253b can be different.

[0057] For example, the radius of curvature of the convex lens portion 253a and the concave lens portion 253b can be 2mm to 4mm, such as 2mm, 2.5mm, 3mm or 4mm.

[0058] Specifically, as one of the optional implementation methods in this embodiment, please continue to refer to... Figure 6 The distance between the filter 253 and the front of the filler 211 can be 5mm to 10mm, and the distance between the filter 253 and the object being scanned can be 500mm to 1000mm. In specific applications, the distance between the filter 253 and the front of the filler 211 and the distance between the filter 253 and the object being scanned can be adjusted appropriately according to the different scanning equipment used.

[0059] For example, the distance between the filter 253 and the front of the filler 211 can be 5mm, 7mm or 10mm, and the distance between the filter 253 and the scanned object can be 500mm, 700mm or 1000mm.

[0060] For example, filter 253 may be made of glass or a polymer material.

[0061] Specifically, the distance from the filter 253 to the scanned object can be 80 to 100 times the distance from the filter 253 to the fill light 211. This design allows the filter 253 to better blur the pixel grid, resulting in better shooting effects.

[0062] Specifically, as one of the optional implementation methods of this embodiment, please also refer to... Figure 2 and Figure 3The filter assembly 25 may further include a drive member 251 for driving the filter 253 closer to or further away from the front of the fill light emitter 211, with the filter 253 connected to the drive member 251. In specific applications, the drive member 251 may preferably be a drive motor. When the fill light emitter 211 is a structured light emitter 21, and the structured light emitter 21 projects a striped grating, the drive member 251 can rotate the filter 253 away from the front of the structured light emitter 21, meaning the filter 253 does not obstruct the front of the structured light reflector, thus preventing the filter 253 from affecting the data acquisition of the scanner 23. However, when the imaging module 22 is capturing images, the drive member 251 can rotate the filter 253 closer to the front of the structured light emitter 21, meaning the filter 253 obstructs and covers the front of the structured light emitter 21, thereby eliminating pixel grid blurring. This design can improve the image quality captured by the imaging module 22 while avoiding affecting the data acquisition of the scanner 23, which is beneficial for improving the accuracy of 3D modeling.

[0063] In one optional implementation of this embodiment, the mounting structure includes a mounting plate 20. The structured light emitter 21, the imaging module 22, and the scanner 23 can all be mounted on the same side of the mounting plate 20, and the structured light emitter 21, the imaging module 22, and the scanner 23 can be arranged sequentially along the length of the mounting plate 20. This design allows the field of view of the structured light emitter 21, the imaging module 22, and the scanner 23 to overlap as much as possible, which is beneficial for improving scanning accuracy and texture acquisition accuracy.

[0064] Specifically, as one of the optional implementation methods of this embodiment, please refer to Figure 2 and Figure 3 The mounting structure also includes a transmitter pad 210 for mounting the fill light 211. One side of the transmitter pad 210 is connected to the mounting plate 20, and the other side of the transmitter pad 210 is connected to the fill light 211. For example, two transmitter pads 210 can be provided, respectively close to the upper and lower surfaces of the fill light 211. The two transmitter pads 210 can have identical structures. The center of the fill light 211 is adjusted to match the adjacent shooting module using the transmitter pads 210 (see reference). Figure 5 (on the same straight line).

[0065] Specifically, as one of the optional implementation methods of this embodiment, please also refer to... Figure 2 and Figure 3Two transmitter pads 210 can be arranged opposite each other. The mounting structure also includes a filter mounting plate 252 for mounting the filter assembly 25. The filter assembly 25 is located between the two transmitter pads 210, that is, between the supplementary light unit 211 and the mounting plate 20. The filter assembly 25 is connected to the mounting plate 20 through the filter mounting plate 252. This design can utilize the space between the transmitter pads 210 to make the overall structure of the scanning assembly 2 more compact and reduce the size of the scanning assembly 2.

[0066] Specifically, as one of the optional implementation methods of this embodiment, please also refer to... Figure 2 and Figure 3 The mounting structure also includes a scanner pad 230 for mounting the scanner 23. One side of the scanner pad 230 is connected to the mounting plate 20, and the other side is connected to the scanner 23. In practical applications, the scanner 23 is generally relatively small. The scanner pad 230 can fit snugly against one side of the scanner 23, allowing it to be stably fixed to the mounting plate 20. This also ensures that the center of the scanner 23 is aligned with the imaging module 22 (see reference). Figure 5 That is, the centers of the two are on the same straight line.

[0067] In practical applications, the volume of the shooting module 22 is generally the largest among the three. When determining the center of the three, the size of the transmitter pad 210 and the scanner pad 230 can be appropriately adjusted based on the shooting module 22 so that the center of the fill light 211 and the scanner 23 coincides with the center of the shooting module 22.

[0068] As one optional implementation of this embodiment, the imaging module 22 can be an optical camera, and the scanner 23 can be an industrial camera. In specific applications, the optical camera and industrial camera in this embodiment can refer to the prior art, and will not be described in detail here.

[0069] As one of the optional implementation methods in this embodiment, please refer to Figure 4 and Figure 5 The scanning assembly 2 also includes a housing 26, with the mounting plate 20, fill light 211, scanner 23, and imaging module 22 all located within the housing cavity. This design facilitates the overall movement of the scanner 23, enabling multi-angle and multi-dimensional scanning and imaging, while also providing the scanning assembly 2 with a certain degree of dust protection, extending the service life of the scanning assembly.

[0070] Specifically, as one of the optional implementation methods of this embodiment, please refer to Figure 3The scanning component 2 also includes a scanning motherboard 24, which can be located inside the housing 26. The structured light emitter 21, the scanner 23, and the imaging module 22 are all electrically connected to the scanning motherboard 24. The scanning motherboard 24 can control the start and stop of each component during scanning and can upload relevant data to a server or cloud.

[0071] The beneficial effects of the scanning component 2 provided in this application embodiment are as follows: Compared with the prior art, the scanning component 2 provided in this application embodiment obtains the data information of the scanned object by scanning with the scanner 23, and uses the fill light 211 to provide supplementary lighting when the shooting module 22 takes a picture of the scanned object, so as to obtain image texture information with uniform light. At the same time, when the fill light 211 projects a monochromatic light image, the filter component 25 covering the front of the fill light 211 filters and eliminates the pixel grid in the monochromatic light image. This makes the monochromatic light image eliminate the pixel grid in the picture taken by the shooting module 22 while providing supplementary lighting to the surface of the scanned object, effectively improving the quality of the texture information obtained by the shooting module 22, making the texture map clearer, which is beneficial to high-standard archival records and the analysis of medical data such as skin analysis.

[0072] This application also provides a scanning device, please refer to... Figure 7 The scanning device includes a support and the aforementioned scanning component 2, which is connected to the support. The support can stably hold the scanning component 2 at a suitable height. In specific applications, the specific structure of the support can be reasonably selected according to the type of scanning device.

[0073] As one of the optional implementation methods in this embodiment, please continue to refer to... Figure 7 The support includes a base 1, a seat assembly 4, a scanning support arm 3, and a background assembly. The seat assembly 4 is disposed on the upper surface of the base 1 and is used for the object to be scanned to sit on. The scanning support arm 3 and the background assembly are located on opposite sides of the base 1. Specifically, one end of the scanning support arm 3 is connected to the base 1, and the other end of the scanning support arm 3 is connected to the scanning assembly 2, so that the scanning assembly 2 is fixed at a suitable height. The scanning support arm 3 and the scanning assembly 2 are located in front of the object to be scanned, and the background assembly is located behind the object to be scanned.

[0074] In specific applications, the seat assembly 4 may have a head support 43 and a back support 42. The head support 43 can be used to support the head of the object being scanned, and the back support 42 can be used to support the back of the object being scanned, preventing the object from shaking randomly and improving the accuracy of the scan. At the same time, it can also make the central axis of the head and the central axis of the torso of the object being scanned coincide with the central axis of the base 1, further improving the scanning effect.

[0075] Specifically, as one of the optional implementation methods of this embodiment, please also refer to... Figure 8 and Figure 9 The scanning support arm 3 includes a first support arm 31, a second support arm 32, and an adjustment structure 30. The first support arm 31 is connected to the scanning component 2, the second support arm 32 is connected to the base 1, and the adjustment structure 30 is located between the first support arm 31 and the second support arm 32. The adjustment structure 30 is used to adjust the height of the first support arm 31, thereby adjusting the height of the scanning component 2 connected to it, which is beneficial for adapting to scanning objects of different heights.

[0076] Specifically, as one of the optional implementation methods in this embodiment, please continue to refer to... Figure 8 and Figure 9 The adjustment structure 30 includes a lifting rack 301, a drive motor 302, and a lifting gear 303. The lifting rack 301 is disposed on the second support arm 32, the drive motor 302 is disposed on the first support arm 31, and the lifting gear 303 is connected to the drive motor 302 and meshes with the lifting rack 301. When adjusting the height, the lifting gear 303 can be driven to rotate by the drive motor 302, so that the first support arm 31 slides along the lifting rack 301, thereby realizing the height adjustment.

[0077] For example, the first support arm 31 and the second support arm 32 can both be in an "L" shape, each including a long arm and a short arm. The long arms of the two are connected by an adjustment structure 30. The short arm of the first support arm 31 is used to connect to the scanning component 2, and the short arm of the second support arm 32 is used to connect to the base 1.

[0078] As one of the optional implementation methods in this embodiment, please refer to Figure 10 The base 1 includes a fixed base 11, a rotating base 12, and a drive structure 10. The upper end face of the fixed base 11 is connected to the seat assembly 4. The rotating base 12 is rotatably connected to the outer periphery of the fixed base 11. The scanning support arm 3 is connected to the rotating base 12. The drive structure 10 is used to drive the rotating base 12 to rotate around the central axis of the base 1, so that the scanning support arm 3 and the scanning assembly 2 rotate around the scanning object for scanning, thereby realizing multi-dimensional scanning data acquisition.

[0079] Specifically, as one of the optional implementation methods in this embodiment, please continue to refer to... Figure 10The rotating base 12 can be annular in structure. The drive structure 10 includes an annular rack 103, a base drive motor 101, and a rotating gear 102. The annular rack 103 is located on the inner edge of the rotating base 12. The base drive motor 101 is connected to the fixed base 11, and the rotating gear 102 is connected to the base drive motor 101 and meshes with the annular rack 103. During scanning, the base drive motor 101 can drive the rotating gear 102 to rotate, thereby causing the rotating base 12 to rotate around the outer periphery of the fixed base 11, thus enabling the scanning assembly 2 to perform multi-dimensional scanning data acquisition.

[0080] For example, the fixed base 11 can be in the form of a disc, and the seat assembly 4 can be connected to the upper surface of the fixed base 11. When the scanning assembly 2 performs rotational scanning, the scanning assembly 2 can rotate around the central axis of the fixed base 11, and the scanning line of the scanning assembly 2 at different positions will intersect with the central axis of the fixed base 11, thereby improving the accuracy of subsequent modeling.

[0081] As one of the optional implementation methods in this embodiment, please refer to [the previous text]. Figure 7 The background assembly includes a background support 50 and a background plate 51. The background support 50 is connected to the base 1, and the background plate 51 is connected to the background support 50, with the background plate 51 facing the back of the object being scanned. Thus, the background plate 51 can block ambient light from behind the object being scanned, improving the accuracy of the scanned data. Simultaneously, the background plate 51 can also absorb light from the front of the object being scanned to a certain extent, reducing light reflection and further improving the scanning effect.

[0082] For example, the background plate 51 can be a black light-absorbing plate, or the background plate 51 can have a light-absorbing layer on the side facing the scanned object to further reduce light reflection. The two sides of the background plate 51 can be bent towards the scanned object to form an arc-shaped structure, which can further block the surrounding light.

[0083] The beneficial effects of the scanning device provided in this application embodiment are as follows: Compared with the prior art, the scanning device provided in this application embodiment can effectively improve the three-dimensional modeling effect by collecting three-dimensional data and surface texture information of the scanning object through the scanning component 2 described above, which is conducive to high-standard archival records and analysis of medical data such as skin analysis.

[0084] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
