Description

Technical Field

[0001] The present application relates to the field of image acquisition, and in particular, to an image acquisition device. Background Art

[0002] Product quality control and authenticity identification (for example, quality inspection and authenticity identification of shoes, skin care products, bags, etc.) are key links in maintaining brand reputation and protecting consumer rights. In the past, traditional product quality inspection mainly relied on manual inspection and simple mechanical measurement, which is not only inefficient but also easily affected by human factors, resulting in unstable and inaccurate test results.

[0003] In recent years, with the rapid development of image processing technology and computer vision technology, image acquisition devices have been widely used in product quality inspection and identification. In the image acquisition process, the setting of the light source has an important impact on the quality of the acquired image. When the image acquisition device is acquiring images, the current mainstream practice is to set the light source in one or two fixed positions. This layout can provide sufficient lighting in most cases to obtain the image of the object.

[0004] Specifically, when the light source is set at only one or two fixed positions, the angle and intensity of the light irradiating the surface of the object will be limited. For example, when the light source is set above the target object, the light mainly irradiates the object from top to bottom, which will cause the direct reflected light on the surface of the object to be strong, while the side area receives less light due to the limitation of the incident angle of the light, resulting in insufficient brightness in the side area, which in turn affects the target image quality of the target object. Utility Model Content

[0005] In view of this, an object of an embodiment of the present application is to provide an image acquisition device capable of improving the quality of a target image.

[0006] In a first aspect, an embodiment of the present application provides an image acquisition device, comprising: a shell, a light source, an image acquisition unit and a storage area; the shell comprises a first side, a second side and a third side; the third side comprises an opening; the image acquisition device is configured to receive or remove a target object through the opening; the storage area is arranged in an area surrounded by the first side, the second side and the third side, and is used to carry the target object; the light source is arranged inside the shell; wherein the illumination direction of the light source is away from at least one of the first side and the second side, and is toward the storage area; the image acquisition unit is configured to acquire a target image of the target object under the illumination of the corresponding light source.

[0007] In the above implementation process, by arranging a light source on the side of the shell, and the illumination direction of the light source is facing away from the corresponding side and toward the storage area, when capturing images of target objects in the storage area, the illumination direction of the light source is facing the side of the target object that needs to be captured, so that the image acquisition device can capture a clearer target image, thereby improving the quality of the target image.

[0008] In one embodiment, the light source is disposed on the first side surface and the second side surface.

[0009] In the above implementation process, by arranging the light source on the first side surface and the second side surface, when the image acquisition unit on the first side surface and the image acquisition unit on the second side surface both perform image acquisition, the light source arranged on the first side surface and the second side surface can respectively provide illumination for the image acquisition unit on the corresponding side surface, so that the image acquisition unit on the corresponding side surface can acquire the target image of the corresponding side of the target object, thereby improving the quality of multiple target images. In addition, by arranging the light source and the image acquisition unit on multiple side surfaces, it is possible to simultaneously acquire images of multiple sides of the target object, thereby improving the efficiency of image acquisition.

[0010] In one embodiment, the first side surface and the second side surface both include a support frame and a transparent support plate; the transparent support plate is fixedly disposed in the support frame; the image acquisition unit is disposed outside the shell, and the image acquisition unit is configured to capture the target image of the target item located in the storage area through the transparent support plate.

[0011] In the above implementation process, by setting the image acquisition unit outside the shell, when the staff operates the image acquisition unit, they can directly operate on the outside of the shell without opening the opening, which simplifies the process of the staff operating the image acquisition unit and improves the operation efficiency. In addition, by setting the shell to include a transparent support plate, even if the image acquisition unit is set outside the shell, the target image of the target object can be obtained through the transparent support plate, which reduces the restrictions on the setting position of the image acquisition unit and increases the flexibility of the position setting of the image acquisition unit.

[0012] In one embodiment, the image acquisition unit includes: a first image acquisition unit and a second image acquisition unit; the first image acquisition unit is arranged outside the support frame at the lower part of the first side; the second image acquisition unit is arranged outside the support frame at the lower part of the second side; wherein the first image acquisition unit and the second image acquisition unit are configured to capture target images of corresponding sides of the target object.

[0013] In the above implementation process, by arranging the image acquisition unit and the light source on both the first side surface and the second side surface, the light sources arranged on the first side surface and the second side surface can respectively provide illumination for the image acquisition unit on the corresponding side surface, so that the image acquisition unit on the corresponding side surface can acquire the target image of the corresponding side surface of the target object, thereby improving the quality of multiple target images. In addition, by arranging the light source and the image acquisition unit on multiple side surfaces, it is possible to simultaneously acquire images of multiple sides of the target object, thereby improving the efficiency of image acquisition.

[0014] In one embodiment, the light source includes: a first light source and a second light source; the first light source is arranged inside a supporting frame at a lower portion of the first side surface; the illumination direction of the first light source is away from the first side surface and toward the storage area; the second light source is arranged inside a supporting frame at a lower portion of the second side surface; the illumination direction of the second light source is away from the second side surface and toward the storage area; wherein the first image acquisition unit is configured to acquire a target image of the target object under the illumination of the first light source; and the second image acquisition unit is configured to acquire a target image of the target object under the illumination of the second light source.

[0015] In the above implementation process, since the target object is placed on the bottom of the shell, by setting the first light source on the lower support frame of the first side and the second light source on the lower support frame of the second side, the first light source can just illuminate the side of the target object facing the first side, and the second light source can just illuminate the side of the target object facing the second side. This can ensure that more light from the first light source and the second light source can be directly directed onto the target object, thereby reducing light scattering and reflection, increasing light intensity, and thereby improving the quality of the target image.

[0016] In one embodiment, the image acquisition unit includes: a third image acquisition unit; the light source includes: a third light source; the third image acquisition unit is arranged outside the support frame at the lower part of the third side surface; the third light source is arranged inside the support frame at the lower part of the third side surface; wherein the third image acquisition unit is configured to obtain a target image of the target object under the illumination of the third light source.

[0017] In the above implementation process, by setting a third image acquisition unit and a third light source on the third side, when acquiring the target image of the target object, after the third side is closed, the third image acquisition unit can acquire the target image of the corresponding side of the target object under the illumination of the third light source, so as to acquire the target images of more sides of the target object, thereby improving the comprehensiveness and acquisition efficiency of the target object image acquisition.

[0018] In one embodiment, the light source is a strip light.

[0019] In the above implementation process, since the light strip is usually composed of multiple lamp beads, it can provide a continuous and uniform linear light source, and the light emitted by the light strip is relatively soft, without strong direct light. By setting the light source as a light strip, the uniformity of the light source illumination can be improved, and the influence of the light source on the reflection and exposure of the target image can be reduced, thereby improving the quality of the target image. In addition, when the light source is set as a light strip, compared with other light sources, the light strip also has better concealment, reducing the probability of the light source appearing in the target image, and improving the quality of the target image.

[0020] In one embodiment, it also includes: a background plate; the shell also includes other sides except the first side, the second side and the third side; the background plate is arranged inside the shell; wherein the background plate is configured to block the other sides.

[0021] In the above implementation process, by setting a background board, and the background board is used to block other sides, it is possible to prevent the image acquisition unit from capturing objects other than the target object, thereby reducing interference in the target image, reducing the difficulty of target image processing, and improving the efficiency of target image processing.

[0022] In one embodiment, the other side surfaces include one or more side surfaces; and a side of the background plate arranged on one or more of the other side surfaces facing the image acquisition unit is arc-shaped.

[0023] In the above implementation process, by setting the side of the background plate facing the image acquisition unit to an arc shape, since the arc shape has relatively fewer folds or connecting lines than other shapes, the appearance of debris in the target image can be reduced and the quality of the target image can be improved.

[0024] In one embodiment, the shell further includes a bottom surface; the background plate is also disposed on the bottom surface; wherein the background plate disposed on the bottom surface is provided with auxiliary lines, and the auxiliary lines are configured to indicate the placement position of the target object.

[0025] In the above implementation process, by setting a background plate on the bottom surface, when the target acquisition unit acquires the bottom surface, impurities in the bottom surface of the target image can be reduced, thereby improving the quality of the target image. In addition, by setting auxiliary lines on the bottom surface to indicate the placement position of the target object, when the staff places the target object in the storage area, they place the target object at the designated position under the guidance of the auxiliary lines, thereby improving the accuracy of the placement of the target object.

[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0034] In the description of the present application, it should be noted that the terms "upper", "lower", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the application products are usually placed when in use. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be interpreted as a limitation of the present application.

[0035] In the description of this application, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "setting", "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] At present, conventional image acquisition devices usually adopt the method of setting the light source only above or below the target object. For example, when acquiring an image of a shoe, an image acquisition device used for authenticity identification usually illuminates the shoe body through the light source above and below the shoe.

[0037] After long-term research, the present invention has found that when the light source is only set above or below the object to be collected, the light mainly shines on the object from top to bottom, or from bottom to top, which will cause the direct reflected light on the surface of the object to be stronger, while the side area receives less light due to the limitation of the incident angle of the light, resulting in insufficient brightness in the side area. For example, when using the light source from above to illuminate, the top details of the shoe, such as texture, material and color, can be well displayed, but the sides and bottom of the shoe often appear dim due to insufficient light, and the details are seriously lost. Although the bottom details of the shoe can be better displayed by using the light source from below to illuminate, the top and sides of the shoe will produce highlight areas due to excessive light intensity, causing the image to be overexposed, which also affects the image quality.

[0038] During the image acquisition process, the uneven distribution of brightness will directly affect the clarity and contrast of the image, making it difficult to accurately capture the detailed information of the side area, thereby reducing the overall quality of the image and affecting subsequent image analysis processes such as feature extraction, color recognition and defect detection, thereby reducing the accuracy and reliability of the entire quality inspection and identification system.

[0039] In view of this, the present application sets a light source on the side of the shell, and the light direction of the light source faces away from the corresponding side and toward the storage area. When capturing images of target items in the storage area, the light direction of the light source faces the side of the target item that needs to be captured, so that the image acquisition device can capture a clearer target image, thereby improving the quality of the target image.

[0040] like Figure 1 , Figure 2 , is a schematic diagram of an image acquisition device provided in an embodiment of the present application, including: a housing 100 , a light source 400 , an image acquisition unit 200 and a storage area 300 .

[0041] The housing 100 includes a first side surface, a second side surface and a third side surface; the third side surface includes an opening; and the image acquisition device is configured to receive or remove the target object through the opening.

[0042] The storage area 300 is disposed in an area surrounded by the first side surface, the second side surface and the third side surface, and is used to carry target items.

[0043] The target object is the object whose image is to be acquired. For example, the target object may be shoes, skin care products, mobile phones, watches, bags, etc. The target object may be selected according to actual conditions.

[0044] In one embodiment, the first side surface, the second side surface and the third side surface are arranged adjacent to each other, wherein the third side surface is arranged between the first side surface and the second side surface.

[0045] Optionally, one of the first side surface, the second side surface or the third side surface is a front view surface for a worker to work on.

[0046] The light source 400 is disposed inside the housing 100 .

[0047] The illumination direction of the light source 400 is away from at least one of the first side surface and the second side surface, and is toward the storage area 300 .

[0048] The light source 400 here can be arranged on the first side surface and / or the second side surface, and can also be arranged on the bottom surface of the housing 100 between the first side surface and / or the second side surface and the storage area 300. The setting position of the light source 400 can be selected according to actual conditions.

[0049] The image acquisition unit 200 here is configured to acquire a target image of a target object under the illumination of a corresponding light source 400 .

[0050] It should be understood that the light source 400 and the image acquisition unit 200 are arranged in a matching manner, that is, one image acquisition unit 200 is configured with at least one light source 400. When the image acquisition unit 200 needs to acquire a target image of a target object, the light source 400 corresponding to the image acquisition unit 200 is turned on, and the image acquisition unit 200 acquires the target image of the target object under the illumination of the corresponding light source 400.

[0051] Exemplarily, if an image acquisition unit 200 is provided on the first side, a corresponding light source 400 is provided on the corresponding first side or on the bottom surface of the shell 100 between the first side and the storage area 300. The light source 400 is matched with the image acquisition unit 200, and the image acquisition unit 200 obtains a target image of the target object under the illumination of the light source 400.

[0052] In one embodiment, the image acquisition unit 200 is disposed outside the housing 100 .

[0053] Optionally, the image acquisition unit 200 acquires a target image of the target object through a transparent area on the housing 100 , or acquires a target image of the target object through an acquisition through hole on the housing 100 .

[0054] Exemplarily, the housing 100 includes a supporting frame 110 and a transparent supporting plate 120 , and the image acquisition unit 200 can acquire a target image of a target object through the transparent supporting plate 120 .

[0055] If the housing 100 is provided with a through hole at the location where the image acquisition unit 200 is provided, the image acquisition element of the image acquisition unit 200 can acquire the target image of the target object through the through hole.

[0056] In the above implementation process, the light source 400 is arranged on the side of the housing 100, and the illumination direction of the light source 400 is facing away from the corresponding side and toward the storage area 300. When capturing images of target objects in the storage area 300, the illumination direction of the light source 400 faces the side of the target object that needs to be captured, so that the image acquisition device can capture clearer target images, thereby improving the quality of the target images.

[0057] In one possible implementation, Figure 2 As shown, the light source 400 is disposed on the first side surface and the second side surface.

[0058] Optionally, there are at least two light sources 400. At least one light source 400 is disposed on the first side, and at least one light source 400 is disposed on the second side. The total number of the light sources 400, and the number of the light sources 400 on the first side and the second side can be adjusted according to actual needs.

[0059] The light source 400 here can be fixedly connected to the first side surface, such as by bonding, welding, etc. The light source 400 can also be detachably connected to the first side surface, such as by screw connection, bolt connection, snap connection, etc. The connection method of the light source 400 to the first side surface can be selected according to actual conditions.

[0060] The light source 400 may be fixedly connected to the second side surface, such as by bonding, welding, etc. The light source 400 may also be detachably connected to the second side surface, such as by screw connection, bolt connection, snap connection, etc. The connection method between the light source 400 and the second side surface may be selected according to actual conditions.

[0061] The connection method between the first side surface and the light source 400 and the connection method between the second side surface and the light source 400 may be the same or different.

[0062] In one embodiment, the light source 400 is disposed at the lower portion of the first side surface and the second side surface.

[0063] In the above implementation process, by arranging the light source 400 on the first side surface and the second side surface, when the image acquisition unit 200 on the first side surface and the image acquisition unit 200 on the second side surface both perform image acquisition, the light source 400 arranged on the first side surface and the second side surface can respectively provide illumination for the image acquisition unit 200 on the corresponding side surface, so that the image acquisition unit 200 on the corresponding side surface can acquire the target image of the corresponding side of the target object, thereby improving the quality of multiple target images. In addition, by arranging the light source 400 and the image acquisition unit 200 on multiple side surfaces, it is possible to simultaneously acquire images of multiple sides of the target object, thereby improving the image acquisition efficiency.

[0064] In a possible implementation, both the first side surface and the second side surface include a supporting frame 110 and a transparent supporting plate 120 .

[0065] The transparent support plate 120 is fixedly disposed in the support frame 110 .

[0066] Optionally, the transparent support plate 120 may be made of transparent glass, transparent plastic, a transparent acrylic plate, etc. The material of the transparent support plate 120 may be selected according to actual conditions.

[0067] The support frame 110 here is a closed structure, and each side of the transparent support plate 120 is connected to the support frame 110 .

[0068] Optionally, the transparent support plate 120 may be fixedly connected to the support frame 110 by bonding, clamping, bolting, screwing, etc.

[0069] The image acquisition unit 200 is disposed outside the housing 100 . The image acquisition unit 200 is configured to acquire a target image of a target object located in the storage area 300 through the transparent support plate 120 .

[0070] The image acquisition unit 200 can be detachably arranged on the support frame 110 . The image acquisition element of the image acquisition unit 200 is located outside the transparent support plate 120 .

[0071] In the above implementation process, by setting the image acquisition unit 200 outside the housing 100, when the staff operates the image acquisition unit 200, they can directly operate outside the housing 100 without opening the opening, which simplifies the process of the staff operating the image acquisition unit 200 and improves the operation efficiency. In addition, by setting the housing 100 to include a transparent support plate 120, even if the image acquisition unit 200 is set outside the housing 100, the target image of the target object can be obtained through the transparent support plate 120, which reduces the restrictions on the setting position of the image acquisition unit 200 and increases the flexibility of the position setting of the image acquisition unit 200.

[0072] In a possible implementation, the image acquisition unit 200 includes: a first image acquisition unit 200 and a second image acquisition unit 200 .

[0073] The first image acquisition unit 200 is disposed outside the support frame 110 at the lower portion of the first side surface; the second image acquisition unit 200 is disposed outside the support frame 110 at the lower portion of the second side surface.

[0074] Here, the first image acquisition unit 200 and the second image acquisition unit 200 are configured to acquire target images of corresponding sides of the target object.

[0075] It should be understood that the first image acquisition unit 200 cooperates with the light source 400 disposed on the first side surface, and the first image acquisition unit 200 acquires a target image of the target object facing the first side surface under the illumination of the light source 400 on the first side surface. The second image acquisition unit 200 cooperates with the light source 400 disposed on the second side surface, and the second image acquisition unit 200 acquires a target image of the target object facing the second side surface under the illumination of the light source 400 on the second side surface.

[0076] Optionally, the first image acquisition unit 200 and the second image acquisition unit 200 can simultaneously acquire the target image of the target object, or can acquire the target image of the target object in different time periods. The linkage mode of the first image acquisition unit 200 and the second image acquisition unit 200 can be selected according to actual conditions.

[0077] In one embodiment, the housing 100 includes a bottom surface, and the storage area 300 is disposed on the bottom surface.

[0078] It can be understood that since the target object is placed on the bottom surface of the shell 100, the first image acquisition unit 200 is placed on the lower support frame 110 on the first side, and the second image acquisition unit 200 is also placed on the lower support frame 110 on the second side. This allows the first image acquisition unit 200 to be directly facing the side of the target object that is facing the first side, and the second image acquisition unit 200 to be directly facing the side of the target object that is facing the second side, thereby minimizing the angle difference between the first image acquisition unit 200 and the second image acquisition unit 200 and the target object, avoiding distortion of the target image, and improving the quality of the target image.

[0079] In the above implementation process, by arranging the image acquisition unit 200 and the light source 400 on both the first side surface and the second side surface, the light source 400 arranged on the first side surface and the second side surface can respectively provide illumination for the image acquisition unit 200 on the corresponding side surface, so that the image acquisition unit 200 on the corresponding side surface can acquire the target image of the corresponding side surface of the target object, thereby improving the quality of multiple target images. In addition, by arranging the light source 400 and the image acquisition unit 200 on multiple side surfaces, it is possible to simultaneously acquire images of multiple surfaces of the target object, thereby improving the efficiency of image acquisition.

[0080] In a possible implementation, the light source 400 includes: a first light source 400 and a second light source 400 .

[0081] Among them, the first light source 400 is arranged inside the support frame 110 at the lower part of the first side; the lighting direction of the first light source 400 is away from the first side and toward the storage area 300; the second light source 400 is arranged inside the support frame 110 at the lower part of the second side; the lighting direction of the second light source 400 is away from the second side and toward the storage area 300.

[0082] Here, the first image acquisition unit 200 is configured to acquire a target image of the target object under the illumination of the first light source 400 ; the second image acquisition unit 200 is configured to acquire a target image of the target object under the illumination of the second light source 400 .

[0083] In the above implementation process, since the target object is placed on the bottom surface of the shell 100, by setting the first light source 400 on the first side lower support frame 110 and setting the second light source 400 on the second side lower support frame 110, the first light source 400 can just illuminate the side of the target object facing the first side, and the second light source 400 can just illuminate the side of the target object facing the second side, so as to make more light from the first light source 400 and the second light source 400 directly hit the target object, reduce light scattering and reflection, increase light intensity, and thus improve the quality of the target image.

[0084] In a possible implementation, the image acquisition unit 200 includes: a third image acquisition unit 200 ; the light source 400 includes: a third light source 400 .

[0085] The third image acquisition unit 200 is disposed outside the support frame 110 at the lower portion of the third side surface; and the third light source 400 is disposed inside the support frame 110 at the lower portion of the third side surface.

[0086] The third image acquisition unit 200 here is configured to acquire a target image of the target object under the illumination of the third light source 400 .

[0087] In one embodiment, a first side of the third side is rotatably connected to a side of the first adjacent side, and a second side of the third side is in contact with a side of the second adjacent side, wherein the first side and the second side are opposite sides, and the third side is configured to rotate around the support frame 110 of the first adjacent side.

[0088] The third side surface includes a support frame 110 and a transparent support plate 120 . The transparent support plate 120 is fixedly disposed in the support frame 110 .

[0089] The support frame 110 of the first side of the third side is rotatably connected to the support frame 110 of the first adjacent side. The third side is configured to open and close the opening by rotating around the support frame 110 of the first adjacent side.

[0090] It should be understood that in order to obtain target images of more sides of the target object, a third side surface and a third light source 400 are provided on the third side surface. When acquiring the target image of the target object, the third side surface can be closed (i.e., the second side of the third side surface is in contact with the second adjacent side surface), and the third image acquisition unit 200 acquires the target image of the corresponding side of the target object under the illumination of the third light source 400.

[0091] In the above implementation process, by setting the third image acquisition unit 200 and the third light source 400 on the third side, when acquiring the target image of the target object, after closing the third side, the third image acquisition unit 200 can acquire the target image of the corresponding side of the target object under the illumination of the third light source 400, so as to acquire the target images of more sides of the target object, thereby improving the comprehensiveness and acquisition efficiency of the target object image acquisition.

[0092] In a possible implementation, the light source 400 is a strip light strip.

[0093] Optionally, the length of the strip light strip can be determined according to the specifications of the target product, or according to the specifications of the support frame 110, or according to the lighting requirements. The method for determining the length of the strip light strip can be selected according to actual conditions.

[0094] For example, if the length of the light strip is determined according to the specifications of the target product, and the target product is a shoe, the heel side of the shoe faces the first side, and the outer ankle side of the shoe faces the second side. The length of the light strip on the first side can be set to be greater than or equal to the width of the heel side, and the length of the light strip on the second side can be set to be greater than or equal to the length of the outer ankle side.

[0095] If the length of the light strip is determined according to the specifications of the support frame 110, the length of the light strip on the first side can be set equal to the length of the support frame 110 at the bottom of the first side, and the length of the light strip on the second side can be set equal to the length of the support frame 110 at the bottom of the second side.

[0096] The above-mentioned setting method of the length of the light strip is only exemplary, and the setting method of the length of the light strip can be adjusted according to actual conditions.

[0097] In the above implementation process, since the light strip is usually composed of multiple lamp beads, it can provide a continuous and uniform linear light source 400, and the light emitted by the light strip is relatively soft, without strong direct light. By setting the light source 400 as a light strip, the uniformity of the light source 400 can be improved, and the reflection and exposure of the target image by the light source 400 can be reduced, thereby improving the quality of the target image. In addition, when the light source 400 is set as a light strip, compared with other light sources 400, the light strip also has better concealment, reducing the probability of the light source 400 appearing in the target image, and improving the quality of the target image.

[0098] In a possible implementation manner, it also includes: a background board.

[0099] The shell 100 further includes other side surfaces except the first side surface, the second side surface and the third side surface; the background plate is arranged inside the shell 100 .

[0100] Optionally, the background board can be a wooden board, a metal board, a cardboard, a paper board, a plastic board, etc. The background board can be selected according to actual conditions.

[0101] The background plate here is a solid color plate, and the background plate is configured to cover other sides.

[0102] Optionally, the other side shielded by the background plate may be a side where the image acquisition unit 200 is not provided, or a side where the image acquisition unit 200 does not perform image acquisition, or a side toward which the image acquisition unit 200 performs image acquisition. The other side shielded by the background plate may be selected according to actual conditions.

[0103] It should be understood that the image acquisition angle of the image acquisition unit 200 is usually much larger than the target object, that is, the target image may include other objects in addition to the target object. For example, the support frame 110, other image acquisition units 200, the light source 400, etc. In particular, when each surface of the shell 100 is a transparent surface, the image acquisition unit 200 can not only capture objects inside the shell 100, but also other objects in the external environment of the shell 100, resulting in too many interference objects in the target image and complicated processing of the target image.

[0104] By setting a background plate, and setting the background plate on the opposite side of the image acquisition unit 200, when the image acquisition unit 200 acquires the target image of the target object, the background of the target object is only the background plate. Therefore, the target image also contains only the background plate and the target object, which can reduce interference in the target image, reduce the complexity of target image processing, and even can be used without additional processing, greatly improving the quality of the target image and improving the efficiency of target image processing.

[0105] The color of the background plate is a color that is easy to handle, such as white, green, etc. The color of the background plate can be selected according to actual needs.

[0106] For example, if the target item is a shoe, the target image is used to be placed on the product details page of the shopping software to show the style of the shoe to consumers. The color of the background board can be set to white, and the target image only includes the white background and the shoe. Before uploading the target image to the product details page, only the position and angle of the shoe in the target image need to be adjusted, and there is no need to distinguish the content in the target image, and then perform operations such as interference removal and background adjustment, thereby reducing the target image processing process.

[0107] If the target item is a shoe, the image of the shoe is used to be placed on the product details page of the shopping software to show the style of the shoe to consumers, where the shoe needs to be displayed in combination with the corresponding scene (e.g., beach shoes are placed on the beach for display, hiking shoes are placed on the stairs for display, etc.). The color of the background board can be set to green, and the target image only includes the green background and shoes. Before the target image is uploaded to the product details page, the shoes in the target image can be cut out and merged into the image with the background of the corresponding scene to obtain the image of the shoe placed in the corresponding scene. Since green is easy to post-process, it can reduce the difficulty of cutting out the target item and improve the efficiency of image processing.

[0108] If the target item is a shoe, the target image is used to be placed on the product details page of the shopping software to show consumers the style of the shoe. If the color of the shoe is white, the color of the background board can be set to black. Before uploading the target image to the product details page, only the position and angle of the shoe in the target image need to be adjusted, and there is no need to distinguish the content in the target image, and then perform operations such as interference removal and background adjustment, thereby reducing the target image processing process.

[0109] In the above implementation process, by setting a background board, and the background board is used to block other sides, it is possible to prevent the image acquisition unit 200 from capturing objects other than the target object, thereby reducing interference in the target image, reducing the difficulty of target image processing, and improving the efficiency of target image processing.

[0110] In a possible implementation manner, the other side surfaces include one or more side surfaces.

[0111] The background plate arranged on one or more other side surfaces has a side facing the image acquisition unit 200 that is arc-shaped.

[0112] It should be understood that the housing 100 of the image acquisition device is usually a cube, a cuboid or other structure. If the background plate that blocks multiple sides is set to other shapes (such as a rectangle), then at the intersection of two adjacent sides, there may be a connecting line or fold between the background plates of the two adjacent sides. When the image acquisition unit 200 acquires a target image of the target object, this connecting line or fold may be acquired in the target image.

[0113] If the side of the background plate that blocks multiple sides and faces the image acquisition unit 200 is set to be arc-shaped, the background plate does not need to adapt to the shape of the housing 100. Therefore, the appearance of connecting lines or folds can be avoided, and the appearance of debris in the target image can be reduced.

[0114] In one embodiment, if there are multiple other side surfaces, the background panels provided on the multiple other side surfaces are integrated background panels.

[0115] It can be understood that by setting the background panels on multiple sides as an integrated background panel, the connection lines or folds between the background panels can be reduced, a relatively clean background can be obtained, and the quality of the target image can be improved.

[0116] In the above implementation process, by setting the side of the background plate facing the image acquisition unit 200 to an arc shape, since the arc shape has relatively fewer folds or connecting lines than other shapes, the appearance of debris in the target image can be reduced and the quality of the target image can be improved.

[0117] In a possible implementation, the housing 100 further includes a bottom surface.

[0118] Wherein, the background plate is also arranged on the bottom surface. The color of the background plate on the bottom surface is consistent with the color of the background plates on other sides.

[0119] The bottom surface here includes a storage area 300, and the bottom surface can be used to place target objects.

[0120] In one embodiment, the background plate disposed on the bottom surface is provided with auxiliary lines, and the auxiliary lines are configured to indicate the placement position of the target object.

[0121] Optionally, the auxiliary line can be a pre-set marking line (such as a pre-printed line, a line drawn in advance with a brush, etc.), or a marking line generated in real time by an indicating device (such as a laser line, infrared light, etc.). The form of the auxiliary line can be selected according to actual needs.

[0122] It should be understood that by setting auxiliary lines on the bottom surface, when the staff places the target object in the storage area 300, they can place the target object at the designated position under the guidance of the auxiliary lines, thereby improving the accuracy of the placement of the target object.

[0123] The following uses the image acquisition device for detecting the quality of shoes as an example to illustrate the specific working process of the image acquisition device in this application example:

[0124] The process of using the image acquisition device provided in the embodiment of the present application to detect shoes is as follows: place the shoes at the position indicated by the auxiliary line in the storage area 300, and turn on the light source 400 corresponding to the image acquisition unit 200 that acquires the shoe image (e.g., the light source 400 whose illumination direction faces away from the first side and the second side). After the light source 400 is turned on, control the corresponding image acquisition unit 200 (the image acquisition unit 200 disposed on the first side and the second side) to acquire the image of the corresponding side of the shoe. Change the orientation of each side of the shoe, turn the side that has not yet acquired the image toward the side of the image acquisition unit 200, and continue to control the corresponding image acquisition unit 200 to acquire the image of the current corresponding side, so as to complete the image acquisition of multiple sides of the shoe. Among them, the images of each side of the shoe acquired only include the color of the shoe and the background board. The images of each side of the shoe captured are input into the corresponding image processing device, so that the images of each side of the shoe are processed accordingly by the image processing device to detect the quality of the shoe.

[0125] In the above implementation process, by setting a background plate on the bottom surface, when the target acquisition unit acquires the bottom surface, impurities in the bottom surface of the target image can be reduced, thereby improving the quality of the target image. In addition, by setting auxiliary lines on the bottom surface to indicate the placement position of the target object, when the staff places the target object in the storage area 300, they place the target object at the designated position under the guidance of the auxiliary lines, thereby improving the accuracy of the placement of the target object.
