Description

[Technical field]

[0001] The present invention relates to an agricultural management support system and method for supporting the sale of agricultural products such as fruits and vegetables, and in particular to an agricultural management support system and method capable of error-free and efficient management of specification information (quality information such as grade and class) at the time of collection and shipping of agricultural products. [Background technology]

[0002] Generally, when collecting and shipping agricultural produce, each producer counts the amount of goods packed by grade and class, fills out a shipping slip for each destination, and transports them to an agricultural cooperative (hereafter referred to as "JA"). JA staff checks whether the quantities of the delivered goods and the shipping slip match for each grade and class, then adds up the amount of agricultural produce from each producer, creates a shipping slip for each destination, and ships them out.

[0003] Because the above tasks are performed manually, there are often mistakes, such as counting or writing incorrectly, which makes the process of checking and correcting these cumbersome. To solve this problem, systems have been proposed to reduce mistakes and problems during the collection and shipping of agricultural produce and to improve work efficiency.

[0004] For example, Patent Document 1 discloses a technology that generates a control number when fresh produce is ordered or whenever a change in situation occurs, and links and manages the control number corresponding to the order contents, thereby enabling flexible and unified management of the ordering or arrival of products such as fresh produce that need to be procured from multiple production areas in response to changes in the product contents.

[0005] Furthermore, Patent Document 2 discloses a technology that uses a main management number that identifies an order process for agricultural products from a logistics center to multiple producers and a sub-management number that identifies the multiple producers, making it possible to identify the order contents of the order process for each main management number and sub-management number.

[0006] Patent documents 1 and 2 describe the use of labels printed with bar codes that identify products for each package (luggage) unit, as well as product names, grades, sizes, ordering destinations, arrival dates, and sources. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] JP2003-141226A [Patent Document 2] JP2003-141225A Summary of the Invention [Problem to be solved by the invention]

[0008] There are several methods for determining crop standards (grades and classes) and selling them. For example, there are methods in which the farmers themselves determine crop standards and sell them (individual selection and individual sales), methods in which the farmers themselves determine crop standards and sell them via agricultural cooperatives (individual selection and joint sales), and methods in which the agricultural cooperatives ultimately determine crop standards and sell them via agricultural cooperatives (joint selection and joint sales).

[0009] Among these, when the producer, the farmer, can determine the specifications before shipping, i.e., in the form of individual selection individual sales and individual selection joint sales, the technology described in Patent Documents 1 and 2 can be used, but when the specifications are determined by the agricultural cooperative, i.e., in the form of joint selection joint sales, the specification information cannot be included in the individual identification number in advance. Of course, even in the form of joint selection joint sales, the farmer can once determine the specifications for each package, issue a label linking the specifications determined by the farmer to the individual identification number, and affix it to the package before carrying it to the agricultural cooperative. However, if the specifications of the agricultural product determined by the farmer differ from those determined by the agricultural cooperative, the agricultural cooperative must reissue a label linking the changed specifications and the individual identification number for the package with the different judgment, which is time-consuming.

[0010] Another method would be for the farm to issue a label that does not include the standard information and affix it to the package, and for the agricultural cooperative to issue a label with the standard information printed on it and affix it to the package. However, this method poses a problem in terms of traceability, since the individual identification information and the standard information are not linked.

[0011] The present invention has been made in consideration of the above-mentioned circumstances, and aims to provide an agricultural support system and method that can efficiently set or change standard information (class information) without interfering with traceability, even when it becomes necessary to set or change agricultural product standard information (class information) at the collection and shipping stage by the agricultural cooperative. [Means for solving the problem]

[0012] In order to achieve the above object, in the farming support system of the present invention, a packaging material for storing agricultural products, the packaging material indicating a position for attaching a first label indicating individual identification information assigned to a packing unit of a package and a position for attaching a second label indicating standard information including a class; an imaging means for acquiring images of one or more packages to which the first label and the second label are affixed; a label detection means for detecting a first label and a second label from the image captured by the imaging means and acquiring label position information representing the positions of the labels in the image; a label associating means for pairing, for each package, the individual identification information of the first label and the standard information of the second label attached to the package based on the label position information; a product information display means for displaying the individual identification information and the standard information for each piece of luggage for which pairing has been completed; The present invention is characterized by comprising:

[0013] Here, the first label and the second label are not limited to being physically separate, but also include being printed on the same label sticker.

[0014] The first label according to the present invention has individual identification information printed thereon that identifies the parcel for each package. On the other hand, the second label does not have any individual identification information, and only information common to multiple parcels or producers, such as agricultural product specification information, is printed thereon. The individual identification information may simply be a number unique to each parcel, or may include information that does not change during the subsequent collection and shipping process, such as the producer and type of agricultural product.

[0015] A user (a farmer or an agricultural cooperative employee) takes a picture of one or more packages using an imaging means. The farm management support system then uses a label association means to link individual identification information and standard information based on the captured image.

[0016] This allows the agricultural cooperative to prepare in advance only the second label with the standard information printed on it, and when setting or changing the standard information for each package, it simply affixes the second label with the appropriate standard information printed on it to the package and takes a picture of the package with the mobile device camera, which automatically links the package's individual identification information to the standard information, thereby making work more efficient.

[0017] Preferably, the label detection means displays an identification frame for each detected label in the image to indicate that the label has been detected, and the label association means displays an identification frame for each of the first and second labels for which pairing has been completed in the image to indicate that pairing has been completed.

[0018] In addition, the label position information of the agricultural management support system according to the present invention has polygonal area information, and the positions for attaching the first label and the positions for attaching the second label displayed on the packaging material have an interval determined based on length information of a predetermined side of the polygon, The label associating means is characterized by pairing the individual identification information of the first label with the standard information of the second label based on label position information of the first label, label position information of the second label, and the length information.

[0019] In addition, information indicating a positional relationship with the second label may be printed on the first label, and the label associating means may select a predetermined side of the polygon based on the information indicating the positional relationship. This makes it possible to pair the first and second labels even if their relative positions change depending on the packaging material, such as left-right or top-bottom.

[0020] The farming support method according to the present invention is a farming support method for supporting collection and shipment of farm products using packaging material for storing the farm products, the packaging material indicating a position for attaching a first label indicating individual identification information assigned to a packing unit of a package and a position for attaching a second label indicating standard information including a grade, the method comprising: A step of attaching a first label indicating individual identification information of the package to the package containing the agricultural produce; The method includes a step of attaching a second label indicating standard information including a class of the luggage to the luggage, and a step of acquiring an image of the luggage by an imaging means, Furthermore, using a computer, detecting the first label and the second label from the image captured by the imaging means and acquiring label position information representing positions of the labels in the image; performing pairing of the individual identification information of the first label and the standard information of the second label attached to each package based on the label position information; and displaying the individual identification information and the standard information for which pairing has been completed for each piece of luggage.

[0021] The program according to the present invention also includes: a label detection means for detecting a first label and a second label from the image captured by the imaging means and acquiring label position information representing positions of the labels in the image; a label associating means for pairing, for each piece of luggage, the individual identification information of a first label and the standard information of a second label attached to that piece of luggage based on the label position information; and a product information display means for displaying, for each piece of luggage, the individual identification information and the standard information for which pairing has been completed. The present invention is characterized in that it functions as a Effect of the Invention

[0022] As described above, in the present invention, even when it becomes necessary to set or change standard information for agricultural products, it is possible to set or change the standard information efficiently without impeding traceability. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] An embodiment of the farm management support system according to the present invention will be described below. In general, agricultural products are sold through agricultural cooperatives by producers harvesting the crops in the field, packing them in cardboard boxes, etc., and transporting them to the agricultural cooperative (JA). The agricultural cooperative then distributes them to the market and delivers them to consumers. The farm management support system according to this embodiment is mainly used for the work of producers and the agricultural cooperative (JA).

[0025] We will briefly explain the workflow of producers who use this system. First, in the preparation stage for shipment on the producer's side, an identification number (individual identification information) is issued for each package unit of cargo such as a cardboard box, and label A (first label) is printed with a QR code (registered trademark, hereafter also referred to as "barcode") containing the identification number, a GS1 code, item, quantity, sales destination, etc., and label B (second label) is printed with a class. These labels can be issued by a printer connected to a local computer or a mobile terminal.

[0026] The producer packs the harvested goods by attaching labels A and B to the cardboard boxes used as packaging materials. Hereinafter, the cardboard boxes containing the agricultural goods will be referred to as “packages.”

[0027] After this work, the producer photographs the package with a mobile terminal and reads from the image the information printed on labels A and B. Fig. 1 is a diagram showing how packages stacked in multiple layers are photographed with a mobile terminal 30. Labels A and B are affixed to each package.

[0028] Next, we will explain the outline of the procedure from reading the information printed on labels A and B on the package with a mobile terminal to registering it on the server. Farmers issue a label (label A) on which individual identification information, including unique serial number information, as well as producer and item information, are printed as barcodes for each package. They also issue a label (label B) on which a barcode indicating the standard (grade or class) is printed. The barcode on label B is not used to identify individual products, so if the standard information is the same, the barcode will be the same.

[0029] Farmers classify the harvested vegetables based on standards and pack them in boxes. They then attach both label A and label B to the boxes and ship them out. At this time, farmers may take a photo of the label using a smartphone (mobile terminal) and register their shipment. The processing on the smartphone in this case involves detecting the barcodes and finding the pairs of the two barcodes (barcode pairing processing), which will be described later.

[0030] The agricultural cooperative checks the specifications of the goods brought in and decides on the final specifications. At that time, if the final specifications differ from the results of the selection made by the farmer, label B containing information on the final specifications will be affixed on top of label B affixed by the farmer. For example, as shown in Figure 2, if the producer (farmer) originally affixed a label with the "Excellent 2L" standard to label B, but the agricultural cooperative's selection certifies it as "Special Excellent L," then a label with the "Special Excellent L" standard will be affixed on top of the original "Excellent 2L" label.

[0031] After all sorting is complete, as shown in Figure 1, the agricultural cooperative employee holds the camera of a mobile device (smartphone or tablet device) over the label and takes a picture. This causes the following barcode pairing process to be executed on the mobile device. Note that the captured image may also be sent to a server, and the pairing process may be executed on the server. The following describes the case where the pairing process is executed on a mobile device.

[0032] The mobile device detects the barcode contained in the image captured by the camera, reads the information indicated by the barcode, and performs the following process for the one that corresponds to label A.

[0033] First, the coordinates of the four corners of label A are obtained. At the same time, the coordinates of the four corners of other barcodes detected that correspond to label B are obtained. Incidentally, labels A and B can be identified based on a code system that indicates whether or not it is individual identification information. Then, the length of one side of the barcode is calculated from the four corners of label A.

[0034] For example, if label B is affixed to the right of label A, the coordinates of the top right and bottom right of label A are compared with the coordinates of the opposing label B, i.e., the top left and bottom left coordinates of label B, and the label B located to the right of label A is selected. The distance between the top right of label A and the top left coordinate of label B, and the bottom right of label A and the bottom left coordinate of label B are also calculated, and if this distance is shorter than the length of one side of the barcode of label A mentioned above, it is determined that label B forms a pair with label A and is processed as the standard information for the package. Note that if multiple labels B are detected, the one that is closest is used.

[0035] The above is the case where label B is located to the right of label A, but even if the positional relationship between labels A and B is different, such as above, to the left, or below, similar processing can be performed to pair the labels.

[0036] The principle of the above-mentioned label pairing process will be explained in more detail with reference to FIG. In Figure 3, label B corresponding to label A1 is shown as label B1, and label B corresponding to label A2 is shown as label B2. The barcodes printed on each label are barcode A1, barcode B1, barcode A2, and barcode B2. These labels and barcodes are not necessarily square. In this example, the upper left corner of the drawing is the origin of the coordinate system, but the origin position is not limited to this.

[0037] Detect barcodes contained in an image taken with a smartphone (mobile device) and obtain the coordinates of each of the four corners (let the obtained barcodes be A1, B1, A2, and B2, and let the four corners be P1 to P4, P5 to P8, P'1 to P'4, and P'5 to P'8, clockwise from the top left).

[0038] The detected barcodes are divided into barcodes A and B based on their contents, and the following processing is performed. The coordinates of the label B side of the rectangle of barcode A1 (i.e., the coordinates of P2 and P3) are obtained, and the length of the side P2-P3 is obtained. Note that the side to be used may change depending on the barcode attachment position.

[0039] Among the detected barcodes B, the one whose upper left corner coordinate (P5, P'5 in Fig. 3) is greater than the x coordinate (x2) of P2 is selected. In the case of Fig. 3, barcodes B1 and B2 are selected.

[0040] Calculate the distance (D1) between the top right corner P2 of barcode A1 and the top left corner P5, P'5 of the selected barcode B, and the distance (D2) between the bottom right corner P3 of barcode A1 and the bottom left corner P8, P'8 of the selected barcode B, and select D1 and D2 that are both smaller than the length h of one side. Note that a distance of up to * times h may be allowed depending on the operation. If multiple labels B are selected, the one with the smallest average value of D1 and D2 is selected as the barcode B that pairs with A1. The information of the paired barcode A1 and barcode B1 is linked and registered as product information. In addition, a message is displayed on the screen of the mobile device indicating that pairing has been completed.

[0041] At the collection and shipping site, agricultural cooperative staff determine the grade and class of the agricultural products. If the result is different from the grade and class displayed on the label already affixed to the package, label B with the revised grade and class is affixed on top of the already affixed label B (the label affixed by the farmer). The agricultural cooperative staff then scans the image of the package with their mobile device. The pairing process at this time is as described above.

[0042] Next, the configuration of the farm management support system 1 according to the first embodiment of the present invention will be described with reference to FIG.

[0043] In Figure 4, the farming support system 1 according to this embodiment is composed of a mobile terminal 30 such as a smartphone, a label printer 50 that outputs labels printed with identification codes etc. to be affixed to luggage, and a management server 10 that connects to multiple mobile terminals 30 via a communication network 2.

[0044] The management server 10 includes a communication unit 11 connected to the communication network 2, a communication processing means 12 that executes communication processing with the mobile terminal 30, and a memory unit 13 that stores various information such as product information 21, producer shipping information 22, producer delivery information 23, and sales destination information 24 sent from the mobile terminal 30.

[0045] Here, producer shipping information 22 is stored in management server 10 when a farmer reads the identification code of the label (particularly label A) affixed to the package using mobile terminal 30 and confirms the quantity. Producer delivery information 23 is stored in management server 10 when an agricultural cooperative employee confirms the quantity of packages brought in using a similar procedure at the collection and shipping site (green center). Seller information 24 is information on sellers registered by agricultural cooperative employees. Product information 21 will be described later.

[0046] The mobile terminal 30 includes a communication unit 31 connected to the communication network 2, a calculation unit 32 that executes calculation processing, an input unit 33 such as a touch panel, a display unit 34 such as a liquid crystal display, and a camera 35. These elements can be configured as an integrated unit.

[0047] The mobile terminal 30 also includes a communication processing means 40 for executing communication processing with the management server 10, an output processing means 41 for outputting labels to the label printer 50, an input processing means 42 for inputting information such as the shipping destination, type of agricultural product, and quantity from the input unit 33, a label detection means 43 for detecting labels A and B affixed to the package, a label association means 44 for pairing (linking) the identification code of label A with the standard information (class) of label B for the labels detected by the label detection means 43, and a product information display means 45 for displaying information about the product stored in the package for which the identification code was detected. Each of the means 40 to 45 can be realized by a program as a function of the CPU.

[0048] The mobile terminal 30 is used by users such as producers (farmers), agricultural cooperative staff, and transport companies, but the data and functions input by the users differ as described below. For example, in an operation in which labels to be affixed to packages are issued by agricultural cooperative staff and distributed to each producer, it is sufficient to make the label printer 50 connectable only to the mobile terminal 30 carried by the agricultural cooperative staff. The label printer 50 may be separated from the mobile terminal 30 and operated offline. In this case, the terminal on the label printer 50 side includes the output processing means 41 and input processing means 42 described above.

[0049] Next, main functions of the farm management support system 1 according to this embodiment will be described. (1) Label issuing function (output processing means 41) In this embodiment, a label (label A) with individual identification information for identifying each package of agricultural produce and a label (label B) with the grade and rank are issued. These labels are then affixed to the package.

[0050] (2) Shipping management function (input processing means 42) Information necessary for shipment management is input from the mobile terminal 30. The input data is transmitted to the management server 10 and stored in the storage unit 13 thereof.

[0051] (3) Label detection function (label detection means 43) Next, the processing procedure of the label detection means 43 will be described with reference to FIG. The following processing is performed for each image captured by the camera at, for example, 60 fps. First, the label position information file is cleared (initialized), and the following process is executed for the entire area (search range) in the image (S101a, S101b).

[0052] It is determined whether a label has been detected within the search range (S102), and if label A is detected ("YES" in S103), its coordinates are registered in the label A column of the label position information file (S104). These coordinates can be rectangular coordinates according to the shape of the label. For example, when a QR code (registered trademark) is used, the rectangular coordinates can be determined based on the coordinates of the finder pattern on the image.

[0053] On the other hand, if label B is detected (NO in S103), its coordinates are registered in the label B column of the label position information file (S105). Then, an identification frame is displayed at the detected label position (label coordinates) (S106). The above process is executed for each of the captured images inputted momentarily.

[0054] (4) Label association function (label association means 44) Next, the processing procedure of the label relating means 44 will be described with reference to FIG. When the label associating means 44 is started after the execution of the label detecting means 43, the label associating means 44 accesses the label position information file (S201).

[0055] Then, the following process is executed for all the labels A registered in the label position information file (S202a, S202b). Now, the ith label A will be described as label Ai.

[0056] The length of a predetermined side (reference length) is calculated based on the rectangular coordinates of the label Ai (S203). Next, it is determined whether or not a label B exists whose coordinates are opposite to the label Ai within a semicircle whose radius is the reference length and whose center is the first reference coordinates of the label Ai (S204). If the result of this determination is "YES", it is next determined whether or not a label B whose coordinates are opposite to the label Ai within a semicircle whose radius is the reference length and whose center is the second reference coordinates of the label Ai (S205).

[0057] In step S203, which side is to be determined, or the first and second reference coordinates in steps S204 and S205, can be determined in advance based on the affixing positions of labels A and B on the package. Note that it is also possible to include information on the affixing positions of labels A and B in label A, and to determine the specific side, or the first and second reference coordinates, based on that information.

[0058] Next, in steps S204 and S205, if a corresponding label B exists, it is determined whether these labels B are the same (S206). If the result of this determination is that the labels B extracted in steps S204 and S205 are the same ("NO" in S207), the label B is paired with the label Ai (S208). On the other hand, if there are multiple extracted labels B ("YES" in S207), the label B with the smallest average distance from the reference coordinate of label Ai to the opposing coordinate of label B is paired with label Ai (S209).

[0059] Then, an identification frame is displayed at the position of the paired label (S210).Then, the identification code of the paired label Ai and the extracted grade / class information of the label B are associated with each other and registered in the storage area of ​​the product information 21 of the server 10 (S211). Through the above process, label A and label B are paired for each image. Information on the paired labels A and B is displayed on the display unit 34 of the mobile terminal 30 by the product information display means 45.

[0060] (Other Examples) The above is an example where label A and label B are independent of each other, but label A and label B may be integrated and displayed on the same label sticker. In Fig. 7(a), label A and label B are independent labels. Meanwhile, Fig. 7(b) is an example in which the contents of label A and label B are printed on the same label sticker. In this case, the farmer attaches the label sticker of Fig. 7(b) to the package and takes it to the agricultural cooperative. If the standard information determined by the agricultural cooperative differs from the standard information on the label sticker affixed by the farmer, the agricultural cooperative affixes label B with the standard information determined by the agricultural cooperative over the area of ​​label B on the label sticker.

[0061] Since the display positions of labels A and B on the label sticker are spaced apart by a certain distance, the individual identification information of label A is linked to the standard information of label B by the processing of the label detection means 43 and label association means 44 described above.

[0062] In the format shown in FIG. 7(a), the labels are output as separate labels, so producers must attach two labels to each box, but they only need to prepare one size of label. The format shown in Fig. 7(b) reduces the burden on producers, as they only need to attach one label because it is printed as a single unit. On the other hand, the agricultural cooperative prints only the common parts and pastes them on top as necessary, so overall it is necessary to prepare two different sizes of labels.

[0063] In this embodiment, even if there is a mixture of parcels with labels A and B attached separately and parcels with the same label sticker printed on them, the user can simply scan all of these parcels together with their mobile terminal, and the individual identification information and standard information will be linked.

[0064] According to the present embodiment, in a joint selection and sales format, if the standard information (grade, class) set by the farmer differs from the standard information determined by the agricultural cooperative, the individual identification information can be accurately linked to the new standard information simply by replacing the label with new standard information and scanning it with a mobile terminal.

[0065] In addition, the agricultural cooperative does not need to issue labels with the standard information linked to the individual identification information printed on them each time the standard information changes, but instead simply needs to prepare labels with the standard information printed on them in advance, thereby making work more efficient.

[0066] The present invention is not limited to the above-described embodiments, and can be realized in various modifications without departing from the spirit and scope of the present invention. For example, it is clear that other identification codes can be used instead of a barcode or a QR code. [Explanation of symbols]
