[0044] To further illustrate the technical solutions provided by the embodiments of the present invention, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0045] In view of the problems in the related art that the pictures of goods taken by the goods inspection table are dim, blurred, and there is local overexposure, resulting in low intelligent recognition rate of goods. The present invention proposes a goods inspection table device and system to enhance the overall illuminance and uniformity of the light source on the operation table surface, improve the quality of the taken pictures, and ensure the intelligent recognition effect of goods.

[0046] Other features and advantages of the present invention will be described in the following description, and some of them will become obvious from the description, or be understood by implementing the present invention. The objectives and other advantages of the present invention can be achieved and obtained through the structures specifically pointed out in the written description, claims, and drawings.

[0047] The embodiments of the present invention provide a goods inspection table device, which uses machine vision technology to realize fast and efficient operations such as intelligent batch recognition, counting, and inspection of goods carried by passengers, such as Figure 1 shown, including:

[0048] An inspection table main body 10, which adopts a box structure and is used to place or connect control devices inside;

[0049] The inspection table main body adopts a box structure and is used to place and connect control devices such as an industrial personal computer, an algorithm server, a timing controller, a hard disk video recorder, a switch, etc. inside.

[0050] An operation table surface 20, located on the top of the inspection table main body 10, including a goods placement area;

[0051] The above-mentioned goods placement area is an area for users to place the goods they carry, and is used for intelligent recognition, counting, and inspection of goods.

[0052] A side box assembly 30, vertically fixed on the inspection table main body 10 and vertically connected to the ceiling assembly 40, which adopts a box structure and is used to place component devices for interacting with users and identity recognition inside. The component devices are connected to the control devices;

[0053] The above-mentioned component devices for interacting with users and identity recognition can include but are not limited to a display screen, a face recognition device, a keyboard and mouse, etc., and are used for information interaction and confirmation between users and control devices.

[0054] A ceiling assembly 40, which adopts a box structure and is vertically connected to the side box assembly 30. At least one light source fill light and at least one camera are placed inside the box. The camera is connected to the control device and is used to collect images of goods. A plurality of fill lights are arranged around one camera in a surrounding manner.

[0055] The above ceiling assembly 40 adopts a box structure, with the light source fill light and the high-definition industrial camera placed inside the box structure. The lenses of the light source fill light and the high-definition industrial camera are oriented towards the operation table surface, and are used for data collection such as photographing and video recording of the goods placed on the operation table surface.

[0056] The commodity inspection table device provided by the embodiment of the present utility model uses machine vision technology to realize intelligent batch identification, counting, and inspection of the goods carried by passengers, effectively solving the problems of time-consuming, laborious, and low-efficiency manual inspection in customs passenger inspection. By reasonably arranging high-definition industrial cameras and surface light source fill lights above the device, the illuminance of the operation table surface light source and the overall uniformity can be enhanced, environmental light interference can be reduced, local overexposure during the shooting process can be effectively suppressed, the quality of the pictures taken by the industrial camera can be improved, and the intelligent identification effect of the goods can be ensured. The device also has traditional inspection functions such as barcode scanning. It can realize quick and efficient operations such as intelligent batch identification, counting, and inspection of the goods carried by inbound passengers at customs.

[0057] In some possible embodiments, such as Figure 2 and Figure 3 shown, the operation table surface 20 further includes a bill recognition area 21. The structure of the bill recognition area is that a transparent material pressing plate 210 is embedded in the operation table surface 20 in a hidden damping rotating shaft 211 manner, and the bill recognition area is flush with the operation table surface. The transparent material pressing plate 210 can adopt a glass pressing plate, and below the glass pressing plate is a bill placement area 212.

[0058] In actual operation, there will be situations where the shopping bills of passengers are folded and wrinkled, affecting the intelligent recognition of photos. To solve this problem, the operation table surface further includes a bill recognition area. A glass pressing plate is designed to flatten and correct the bill wrinkles. The surface of the glass pressing plate adopts a special process to reduce the influence of the reflection on the glass surface on the photo quality. The glass pressing plate adopts a hidden damping rotating shaft, supports one-handed opening, and the position can automatically stay fixed, which is convenient for users to operate. The bill recognition area adopts an embedded design and is basically flush with the operation table surface, which can take into account the placement and recognition of other goods and provide the maximum operation space on the table surface for users.

[0059] In some possible embodiments, such as Figure 2 shown, the number of commodity placement areas 22 is at least two, and the bill recognition area 21 overlaps with one of the commodity placement areas 22. Of course, one commodity placement area can also be arranged, or more than two commodity placement areas can be arranged. The number of bill recognition areas can be one or more. When there are multiple bill recognition areas, they can overlap with the corresponding one commodity placement area respectively. Of course, a dedicated bill recognition area independent of the commodity placement area can also be set on the operation table surface.

[0060] Such as Figure 4As shown in the figure, in the embodiment of the utility model, the ceiling assembly is arranged with multiple cameras respectively aligned with each commodity placement area and one camera aligned with the bill recognition area. The FOV (Field of View) 23 of each camera is aligned with one commodity placement area, and the boundary parts of the FOVs of two adjacent cameras overlap. The overlapping area 24 of the FOV boundaries of the two cameras is relatively small, and the FOV boundaries of all cameras cover the commodity placement area.

[0061] The commodity placement area on the operation table surface of the commodity inspection table device is used for placing commodities. The cameras in the ceiling assembly that are aligned with the commodity placement area are used to take pictures of the commodities for intelligent recognition, and the camera in the ceiling assembly that is aligned with the bill recognition area is used to take pictures of the bills for intelligent recognition. Exemplarily, for commodity recognition, the range of the operation table surface can be covered by superimposing 2 industrial cameras of appropriate specifications. For shopping bill recognition, since the bills are usually small in size and small in text, in order to improve the recognition accuracy, another industrial camera is set, and the shooting range is aligned with the shopping bill recognition area on the operation table surface, which is specifically used for bill recognition. The coverage scheme of the operation table surface is specifically as Figure 5 As shown in the figure, the ceiling assembly is arranged with multiple cameras respectively aligned with each commodity placement area and one camera aligned with the bill recognition area. The FOVs 23 of two cameras are aligned with one commodity placement area, and the FOV 25 of one camera is aligned with the bill recognition area.

[0062] The position and quantity arrangement of the industrial cameras in the ceiling assembly are determined by the size of the inspection operation table surface area, the camera specifications, and the height of the ceiling from the table surface. The basic rule for reasonably arranging the position and quantity of the cameras is: select high-definition industrial cameras with high resolution and large FOV. The layout of the camera positions is such that the field of view boundaries formed by the FOVs of all the cameras cover the commodity placement area and do not exceed the set proportional threshold of the commodity placement area. Exemplarily, it should not exceed 10% of the operation table surface range to avoid wasting the photographing pixels and try to increase the proportion of the effective pixels of the item imaging; for the position arrangement of the industrial cameras, it is also necessary to consider that at the theoretical junction of the FOVs of two cameras, in order to ensure that the items are effectively recognized, the field of view boundaries formed by the FOVs of two adjacent cameras partially overlap, and the ratio of the overlapping width dimension to the field of view width dimension formed by the FOVs of two adjacent cameras is in the range of 5% - 10%.

[0063] As Figure 6 As shown in the figure, three high-definition industrial cameras 41 are arranged on the ceiling assembly 40. After the position arrangement of the industrial cameras is determined, the position, quantity, and size of the fill lights need to be comprehensively arranged around the industrial cameras. As Figure 6 As shown in the figure, 3 fill lights 42 are set. As Figure 7 Shown in the figure is a schematic diagram of the FOVs corresponding to the three high-definition industrial cameras 41.

[0064] The factors mainly considered in the supplementary light arrangement scheme in the embodiments of the present utility model include:

[0065] The supplementary lights are arranged on the bottom surface of the ceiling assembly, and the light direction is directly facing the operation table; the supplementary lights should adopt a planar diffusion plate with high light transmittance, high diffusivity, and high haze characteristics to convert the point light source into a soft and uniform surface light source.

[0066] The diffusion plate area of the supplementary lights should be as large as possible to improve the lighting uniformity of the operation table; actually, due to the position constraint of the industrial camera, it is impossible to achieve a complete integrated diffusion plate, and the diffusion plate of the supplementary lights may be divided into several non - continuous parts by the industrial camera; through experimental verification, the ratio of the total coverage area of the diffusion plates of all supplementary lights to the area of the operation table is not lower than the set ratio threshold, such as not lower than 25%, to meet the lighting uniformity requirements of the operation table.

[0067] For several non - continuous supplementary lights, the length - width ratio of a single supplementary light diffusion plate should be in the range of 1 - 2.5, that is, a smaller length - width ratio should be maintained. The larger the length - width ratio, the more the surface light source tends to be a line light source, affecting the lighting uniformity of the operation table.

[0068] The supplementary lights should be arranged as close as possible around the industrial camera, and the distance between the diffusion plate and the industrial camera should be within 80 mm; the closer the distance, the more the light reflected by the commodity and entering the camera will be captured by the camera lens in a nearly vertical manner (close to 0° incident angle), thereby reducing the local reflection caused by large - angle oblique incidence.

[0069] By arranging the supplementary lights according to the above - mentioned supplementary light arrangement scheme in the embodiments of the present utility model, the illuminance difference between the center and the edge of the operation table can be reduced, the overall uniformity can be improved, the bright and dark of the photographed commodity pictures are uniform, and there is no local over - exposure, thus providing high - quality picture data for algorithm intelligent recognition.

[0070] Exemplarily, as Figure 8 shown, the area specification of the supplementary light is 300 mm * 300 mm, three high - definition industrial cameras 41 are arranged, and four supplementary lights 42 are arranged around the high - definition industrial camera 41. As Figure 9 shown, the area specification of the supplementary light is 600 mm * 300 mm, four high - definition industrial cameras 41 are arranged, and two supplementary lights 42 are arranged around the high - definition industrial camera 41.

[0071] The supplementary light scheme in the embodiments of the present utility model is not limited to the layouts of the above two examples, and other implementation schemes that conform to the above - mentioned supplementary light layout design ideas can also achieve similar supplementary light effects.

[0072] In the embodiments of the present utility model, the side box assembly 30 is a single - arm type assembly, as Figure 10As shown, a top support crossbeam 31 extends horizontally from the top of the side box assembly 30. One end of the top support crossbeam 31 is fixedly connected to the body of the side box assembly 30, and the other end is fixedly connected to the ceiling assembly. In the embodiment of the present invention, there is a fastening screw 32 above the side box assembly 31, and this fastening screw 22 is fixedly connected to the top support crossbeam 31.

[0073] In the embodiment of the present invention, the top support crossbeam 31 is located at the inner top of the side box assembly 30. When one end is fixedly connected to the body of the side box assembly 30, the fixable ways can be connection by welding and the fastening screw 32, and it is solidified as a part of the side box assembly. The other end is connected and fixed to the ceiling assembly, playing a role of supporting and bearing the cantilever end of the ceiling assembly 30.

[0074] As Figure 12 shown, it is a schematic diagram after the ceiling assembly 30 is fixed to the side box assembly through the top support crossbeam 31 in the embodiment of the present invention. The high-definition industrial camera and the fill light are arranged inside the box body of the ceiling assembly. In the embodiment of the present invention, by reasonably and compactly arranging the industrial camera and the fill light, the volume of the ceiling is effectively reduced. At the same time, the ceiling box body is made of aluminum alloy material, effectively reducing the weight of the ceiling, so as to realize the design of a single-sided cantilever type without a support column for the ceiling, eliminating the support column, which not only expands the user's tabletop operation space but also improves the aesthetic degree of the product.

[0075] In some possible embodiments, as Figure 11 and Figure 13 shown, the ceiling assembly 40 includes a fixing member 43 located at the upper part of the box body structure of the ceiling assembly and fixedly connected to the two sides of the ceiling assembly;

[0076] The fixing member 43 includes a first group of screws 431 and a second group of screws 432;

[0077] The end face of the first group of screws 431 contacts the lower top support crossbeam 31. By controlling the screwing-in position of the first group of screws 431, the distance between the ceiling assembly 30 and the top support crossbeam 31 is adjusted to drive the adjustment of the height of the ceiling assembly 30 in the vertical direction;

[0078] The end face of the second group of screws 432 directly passes through the lower top support crossbeam 31, and the second group of screws 432 is fastened to the top support crossbeam 31 through a nut.

[0079] In the embodiment of the present utility model, the first group of screws 431 can adjust the height of the ceiling assembly in the vertical direction, ensuring that the height of the ceiling assembly from the operation tabletop is always within the allowable range of the design, preventing the problem that the cantilever end of the ceiling sags due to transportation or long-term use, and further causing the displacement of the photographing and focusing range of the industrial camera. The second group of screws 432 is used for fastening in the horizontal direction to prevent shaking and displacement. The first group of screws 431 includes at least one screw. Exemplarily, it can include 2 screws. The second group of screws 432 includes at least one screw. Exemplarily, it can include 2 screws.

[0080] In the embodiment of the present utility model, the following method can be adopted to adjust the first group of screws 431 and the second group of screws 432: Vertically adjust the end face of the first group of screws to contact the lower top support cross beam. By controlling the screwing-in position, the distance between the ceiling and the top support cross beam can be adjusted; After directly passing the second group of screws through the lower top support cross beam, fasten it to the top support cross beam with a nut to achieve effective fixation in the horizontal direction and prevent shaking and displacement.

[0081] Based on the same inventive concept, the embodiment of the present utility model also provides a commodity inspection table system, as Figure 14 shown, including:

At least one light source supplementary lamp and at least one camera are placed inside the box. The camera is connected to the control device and is used for collecting images of commodities. A plurality of supplementary lamps are arranged around one camera in a surrounding manner;

[0083] A server 1402, connected to the control device of the commodity inspection table device, is used for communicating with the control device to conduct commodity inspection.

[0084] For the specific implementation manner of the above commodity inspection table device, refer to the description of the above embodiment, which will not be repeated here. The commodity inspection table device is connected to the server through a network. The above commodity inspection table device is used for photographing the commodities to be inspected on the supervision table, identifying the obtained images to obtain commodity information, communicating with the server to obtain commodity information in the database, and matching the identified commodity information with the commodity information in the database. When it is determined that there is matching commodity information in the database, the commodity inspection passes.
