Description

Technical Field

[0001] This application relates to the field of image recognition technology, and particularly to a method and device for updating electronic price tags of vending machines. Background Art

[0002] Currently, vending machines include two types: rail machines and visual dynamic cabinets. Rail machines send out goods through rails, and users cannot directly take goods from the cabinet at will. Dynamic visual cabinets allow users to open the cabinet door and take out and put back goods according to their own needs.

[0003] Whether it is a rail machine or a visual dynamic cabinet, when users purchase goods from them, they need to obtain product information and prices in order to select the required goods accordingly. For rail machines, product labels are usually set near the goods, and product information and prices are written on the product labels. However, for the new retail industry that needs to continuously update goods, the goods, their prices, and the positions of the channels in the vending machine are also constantly changing. This method requires the operators managing the vending machines in the area to manually replace the product labels for such changes, resulting in a huge operation burden. For visual dynamic cabinets, QR codes or interactive screens are usually set up, and users can obtain product information and prices by scanning the QR codes or directly on the interactive screens. However, the product information and prices also need to be manually configured by the operators in the background, and this method cannot display the product information and prices together with the physical goods to the users, resulting in an unclear perception of the product prices by the users.

Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0020] It should be noted that in the description of the embodiments of the present application, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

The orientation or positional relationship indicated by terms such as "upper", "lower", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present application. Unless otherwise expressly specified and limited, the terms "mount", "connected", "coupled" should be construed broadly, 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 directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0021] The terms "first", "second", etc. in the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same category, and do not limit the number of objects. For example, the first object can be one or more. In addition, "and / or" indicates at least one of the connected objects, and the character " / ", generally indicates an "or" relationship between the associated objects before and after.

[0022] Figure 1 is one of the flow diagrams of the vending machine electronic price tag update method provided by the embodiments of the present application. Refer to Figure 1 , the embodiments of the present application provide a vending machine electronic price tag update method, which may include: 101. Obtain the target front image of the vending machine with the goods placed; 102. Identify the corresponding relationship between the goods already placed in the vending machine and the electronic price tags in the target front image; 103. Send the product information and the latest price of the goods already placed to their corresponding electronic price tags to update the display information of the electronic price tags.

[0023] In step 101, after the operator finishes placing the goods, the operator can take a photo of the front image of the vending machine and upload the front image to the server through the mobile client. After being processed by the server, the target front image is obtained. At the same time, the vending machine is controlled to enter the electronic price tag update mode through the mobile client.

[0024] In steps 102 to 103, the electronic price tag can be connected to the central control device by wired or wireless means. After the server identifies the corresponding relationship between the placed goods and the electronic price tag in the target front image and determines that the cabinet door of the vending machine is closed, an update instruction will be sent to the central control device to update the display information of the electronic price tag through the central control device.

[0025] The method for updating the electronic price tag of the vending machine provided in this embodiment obtains the target front image of the vending machine after the goods are placed, identifies the corresponding relationship between the placed goods in the vending machine and the electronic price tag in the target front image, and sends the goods information and the latest price of the placed goods to the corresponding electronic price tag to update the display information of the electronic price tag. By obtaining the target front image and identifying the corresponding relationship between the goods and the electronic price tag therein, this embodiment can associate the goods with the electronic price tag, and then control the electronic price tag to display the goods information and the goods price of the associated goods, realizing the automatic update of the goods information and the goods price, without the need for the operator to manually replace or configure, reducing the operation pressure. And because the electronic price tag is set in the vending machine, the goods information and the goods price in the vending machine can be displayed to the user together with the physical goods, enhancing the user's perception of the goods price.

[0026] Figure 2 It is the second flow chart of the method for updating the electronic price tag of the vending machine provided in the embodiment of the present application. Refer to Figure 2 , in one embodiment, obtaining the target front image of the vending machine after the goods are placed may include: 201. Obtain the initial front image of the vending machine; 202. When at least two positioning marks distributed along the diagonal exist in the initial front image, determine the initial front image as the target front image.

[0027] The positioning marks are pre-set in the upper left lane, upper right lane, lower left lane, and lower right lane of the vending machine.

[0028] In step 201, the initial front image needs to focus on the shelf area of the vending machine.

[0029] In step 202, that is, when there is at least a top - left positioning identifier and a bottom - right positioning identifier in the initial front - facing image, or at least a top - right positioning identifier and a bottom - left positioning identifier, it is determined that the shelf area of the initial front - facing image has been completely photographed. Therefore, the initial front - facing image can be determined as the target front - facing image.

[0030] In this embodiment, by setting positioning identifiers at the four - corner aisles of the shelf area, it is possible to determine whether the shelf area in the photographed initial front - facing image is completely displayed based on the display of these positioning identifiers in the initial front - facing image, which helps to improve the accuracy of subsequent recognized information.

[0031] Figure 3 It is the third flowchart of the vending machine electronic price tag update method provided by the embodiments of the present application. Refer to Figure 3 , in one embodiment, identifying the corresponding relationship between the placed goods in the vending machine and the electronic price tag in the target front - facing image may include: 301. Based on the preset position relationship between the aisles in the vending machine and the pre - placed goods in the aisles, identify the placed goods corresponding to the aisles in the target front - facing image; 302. Identify the electronic price tag corresponding to the aisle in the target front - facing image; 303. Associate the placed goods corresponding to the same aisle in the target front - facing image with the electronic price tag to obtain the corresponding relationship between the placed goods in the vending machine and the electronic price tag in the target front - facing image.

[0032] In step 301, there is a preset position relationship between the aisles in the vending machine and the pre - placed goods in them. For example, it is desired to place product A in the aisle at row M1 and column N1, and place product B in the aisle at row M2 and column N2, etc. Then, product A is associated with the aisle at row M1 and column N1 in advance, and product B is associated with the aisle at row M2 and column N2 in advance to obtain the preset position relationship between the products and the pre - placed goods in them. Furthermore, in the target front - facing image, the placed goods corresponding to the aisles in the same row and column can be identified.

[0033] In step 302, each aisle in the vending machine is provided with a corresponding electronic price tag, but how they correspond specifically still needs to be further determined and identified.

[0034] In step 303, after obtaining the corresponding relationship between the aisle and the placed goods in the target front - facing image, and the corresponding relationship between the aisle and the electronic price tag, the corresponding relationship between the placed goods and the electronic price tag can be obtained by using the aisle as an intermediary.

[0035] In this embodiment, the corresponding relationship between the product aisle and the product in the target front image is first identified, and then the corresponding relationship between the product aisle and the electronic price tag in the target front image is identified. Furthermore, taking the product aisle as a medium, the corresponding relationship between the product and the electronic price tag is accurately determined, which helps to accurately update the electronic price tag subsequently.

[0036] Figure 4 It is the fourth flow chart of the method for updating the electronic price tag of the vending machine provided by the embodiment of the present application. Refer to Figure 4 , in one embodiment, based on the preset positional relationship between the product aisle in the vending machine and the products pre-placed in the aisle, identifying the products already placed corresponding to the product aisle in the target front image may include: 401. Based on the shelf size and positioning marks in the vending machine, determine the aisle image corresponding to the product aisle in the vending machine in the target front image; 402. Based on the preset positional relationship, determine the products pre-placed in the aisle corresponding to the aisle image as the products already placed corresponding to the aisle image.

[0037] In step 401, based on the shelf size and positioning marks in the vending machine, the boundary of the shelf area and the distribution of the product aisles within the shelf area in the target front image can be determined, so as to accurately determine the aisle image corresponding to the product aisle in the vending machine in the target front image.

[0038] In step 402, that is, determining that the products already placed corresponding to the aisle image in the same row and column as the product aisle in the vending machine in the target front image are the products pre-placed at the product aisle in the vending machine.

[0039] In this embodiment, based on the physical position of the product aisle in the vending machine, its aisle image in the target front image is determined, and then based on the preset positional relationship between the product aisle entity and the products therein, the products corresponding to the aisle image are determined, so as to achieve an accurate correspondence between the aisle image and the products in the target front image.

[0040] Figure 5 It is the fifth flow chart of the method for updating the electronic price tag of the vending machine provided by the embodiment of the present application. Refer to Figure 5 , in one embodiment, identifying the electronic price tag corresponding to the product aisle in the target front image may include: 501. Identify the electronic price tag image corresponding to the electronic price tag in the vending machine in the target front image; 502. Based on the preset positional relationship between the product aisle and the electronic price tag in the vending machine, determine the electronic price tag image corresponding to the aisle image; or determine the electronic price tag image located below the aisle image and closest to the aisle image as the electronic price tag image corresponding to the aisle image.

[0041] In step 502, similar to the product channels and the pre-arranged products in the vending machine, the positional relationship between the product channels and the electronic price tags can also be preset. For example, the product channel in row M1 and column N1 is associated with the electronic price tag in row M1 and column N1, the product channel in row M2 and column N2 is associated with the electronic price tag in row M2 and column N2, etc. Furthermore, the product channel image and the electronic price tag image with the same positional relationship in the target front image can be associated; Furthermore, if the positional relationship between the product channels and the electronic price tags is not preset in advance, then in the target front image, the product channel image can be directly associated with the electronic price tag image closest to it below.

[0042] In this embodiment, the electronic price tag image in the target front image is first recognized. Then, when the positional relationship between the product channels and the electronic price tags in the vending machine is preset in advance, the electronic price tag corresponding to the product channel in the target front image is recognized based on this positional relationship. When the positional relationship between the product channels and the electronic price tags in the vending machine is not preset in advance, the electronic price tag closest to the product channel below in the target front image is directly determined as the electronic price tag corresponding to the product channel, so as to accurately recognize the corresponding relationship between the product channels and the electronic price tags in the target front image in different situations.

[0043] Figure 6 It is the sixth flowchart of the method for updating the electronic price tag of the vending machine provided by the embodiment of the present application. Refer to Figure 6 , in one embodiment, recognizing the electronic price tag image corresponding to the electronic price tag in the vending machine in the target front image may include: 601. Control the electronic price tag in the vending machine to display a preset pattern; 602. Based on the preset pattern, recognize the electronic price tag image corresponding to the electronic price tag in the vending machine in the target front image.

[0044] In step 601, the preset pattern can be set according to actual needs and is not limited here. In this embodiment, the preset pattern can be set as a combined pattern of specific shapes.

[0045] In step 602, that is, recognize the preset pattern in the target front image, and thus determine the recognized preset pattern image as the electronic price tag image.

[0046] In this embodiment, by controlling the electronic price tag in the vending machine to display a preset pattern, the electronic price list can be highlighted in the target front image, thereby increasing the recognition accuracy of the electronic price tag in the target front image. At the same time, when the styles of the electronic price tags in the vending machine are different, different preset patterns can be controlled to be displayed respectively, so that the electronic price tags can be distinguished and recognized in the target front image, or the same preset pattern can be controlled to be displayed, so that the electronic price tags can be compatibly recognized in the target front image, improving the recognition accuracy and compatibility.
