Specifically, FIG. 4A is a diagram illustrating an example of product information, and FIG. 4B is a diagram illustrating an example of container information.

Product information (article information) is stored in association with product classification, product code (article code), product name such as croquettes and salads, name of production area, unit weight (unit mass data), standard unit, container code, unit price, etc. doing.
In addition, when specifying an article (product) with imaging data (image data) obtained by imaging the article (product) with the imaging unit 8 (imaging means), product specifying information (product specifying information for specifying the product in the product information is: (Data obtained by quantifying product dimensions, colors, shapes, etc.).

  Container information includes container code, container name (container type) such as rectangular container and round container, container identification information (specific information), sales form information, product code (article code), container mass data (tare weight data) , Or tare mass data), etc. are stored in association with each other. The container specifying information is information indicating the area of the container (the area of the container when the imaging unit 8 images the container), the shape of the container, and the like. The information indicating the shape of the container is not limited to the shape, area, color, and the like when the container is imaged from above. For example, the imaging unit 8 (imaging unit) images the bottom of the article (product) and captures the imaging data. In the case of acquiring (image data), the shape of the bottom of the container, the area of the bottom, the color of the bottom, and the like become container specifying information (specific information), and the imaging direction of the imaging unit 8 (imaging means) is the side edge of the container. In the case of both (front and rear, left and right), the shape of the side end of the container, the area of the side end, the color of the side end, and the like become the container specifying information (specific information). As the sales form information, for example, 0 is indicated in the case of quantity sales, and 1 is indicated in the case of quantity sales. In other words, the sales form information indicates whether or not the sales form by the container is a weighing sale. The container specifying information is set on the setting screen, and an empty container placed on the placement unit of the weighing unit 7 is imaged by the imaging unit 8 and binarized to obtain the area of the container. The acquired area is stored in a storage unit such as the RAM 3 as container specifying information (specific information) of the container. Note that the container specifying information is not limited to the area, and may be, for example, the number of dots obtained by binarizing the container, or the external shape (silhouette), three-dimensional actual dimensions (vertical, horizontal, height). In addition, a combination of the color and pattern on the surface of the container may be used.

  In the present embodiment, the type of the container (tray) and the type of the article stored in the container (tray) are associated with each other and stored in the storage unit. In addition, the type of container (tray) and sales form information are associated with each other and stored in the storage unit.

  FIG. 5 is a diagram showing an example of a setting screen by the merchandise sales data processing apparatus 100. Specifically, an example of a screen for setting information about a container such as a tray (container) size is shown.

The setting screen is obtained by performing binarization processing on the capture button 60, an image (capture image 61) such as a product captured by the imaging unit, and the image (capture image 61) based on the set threshold value. The binarized image (the converted image 62), a plurality of operation buttons 63 for setting a threshold value for binarization processing, a threshold value display unit 64 for displaying a threshold value, and a plurality of operation buttons for setting a protrusion threshold value 65, a protrusion threshold value display portion 66 for displaying a protrusion threshold value, a tray size display portion 67 indicating the size of the tray (container), a setting button 68 for setting the size of the tray (container), and an end button for ending the setting 69, etc.
The tray size display section 67 displays the number of pixels or the area of the tray (container) corresponding to the tray (container) in the binarized image (the converted image 62) (white portion in FIG. 5). .

  By operating the up button 63u or the down button 63d related to the binarization process, the threshold value of the binarization process can be finely adjusted manually. When the automatic setting button 63a for automatically setting the threshold value of the binarization process is operated, a predetermined threshold value is set based on the illuminance (luminance) of the surrounding environment.

As this error processing, the container selection screen is displayed on the display unit. Processing may be performed. On the container selection screen, an image showing the types of a plurality of containers stored in the storage unit is displayed. An operator (such as a user) looks at the container selection screen displayed on the display unit and selects the same type of container as the actual one. The control unit 1 performs a process of specifying the container based on the signal input from the operation unit. By doing so, even if there is an error in the image recognition processing, the control unit 1 can easily identify the container based on the signal from the operation unit.

  Further, when an error is detected by the plurality of protrusion detection units 61c, if the number of the “protrusion detection units 61c” less than the threshold is less than a predetermined number, the control unit 1 may make an error. By doing so, the error detection accuracy can be improved.

  In fact, since the hand is also determined as a part of the container, the area of the container (for example, the total number of dots) may happen to coincide with another container. Since there is a possibility of processing by judging, the overhang detection unit 61c is provided.

  In addition, when the protrusion detection unit 61c cannot be detected, the control unit 1 performs error processing. For example, when a seal (specific information) that specifies the sales form of the container is detected in the imaging data, the control unit 1 From the sticker (specific information), it may be determined whether it is a product sold by quantity or a product sold in quantity, and a container selection screen may be displayed. In addition, it is not only the case where the protrusion detection part 61c cannot be detected, but the container (product) mounted on the mounting part is a product sold by weight only by a seal (specific information) specifying the sales form affixed to the container. It may be determined whether or not. In this case, the seal specifying the sales form affixed to the container may be, for example, a seal made of a graphic specifying the sales form, a label printed with code information specifying the sales form, or the like. Moreover, the seal | sticker which specifies the sales form affixed on a container may be affixed on any place of a container, if it is a place which can be imaged.

Although the kind and sales form of a certain article (product) are specified, it is not limited to this form. For example, the type of article such as croquette or azimuth fly may be specified based on the imaging data (image data) captured by the imaging unit 8. In the embodiment, the container placed on the placement unit is imaged from above. However, the present invention is not limited to this. For example, the imaging unit 8 (imaging unit) images the bottom of an article (product) and captures the image data. (Image data) may be acquired, or the imaging direction of the imaging unit 8 (imaging means) may be the side end (both front and rear and left and right) of the container. In this case, when the imaging direction of the imaging unit 8 (imaging means) is from the bottom of the container, the container specifying information (specific information) for specifying the container includes the shape of the bottom of the container, the area of the bottom, the color of the bottom, and the like. When it becomes container specific information (specific information) and the imaging direction of the imaging unit 8 (imaging means) is the side end (both front and rear, left and right) of the container, the container specific information (specific information) for specifying the container is the container The shape of the side end, the area of the side end, the color of the side end, and the like are container specifying information (specific information).

Next, a specific example of the embodiment of the present invention will be described.
FIG. 10 is a diagram for explaining an example of the specific information. Specifically, FIG. 10A is a diagram illustrating an example of a seal 70 (70a, 70b, 70c) having a color or shape defined as the specific information. FIG. 10B is a diagram showing an example of a container 75 with a seal 70b attached as specific information, and FIG. 10C is a diagram showing an example of a container 75 with a seal 70c attached as specific information.

  In the above-described embodiment, the specific information for specifying the container stored by the storage unit is the area of the container (the number of dots corresponding to the area of the container, etc.), but is not limited to this form. The specific information may be, for example, the shape and color of the seal 70 as shown in FIG. Moreover, the label etc. which code information (for example, a one-dimensional code, a two-dimensional code, etc.) which specifies a sales form may be printed.

The color of the colored portion of the seal 70 is, for example, a predetermined color such as red, blue, yellow, or green, and is defined by a hue, a color number, or the like. As the shape of the colored portion of the figure of the seal 70, for example, a quadrangular shape, a circular shape, a triangular shape, a polygonal shape, or the like can be adopted.
The seal 70 is formed with a colored portion of a figure and a white area (white portion) so as to surround the colored portion outside by a predetermined distance. By providing the white portion, the color of the product and the color of the colored portion of the seal 70 can be easily distinguished, and the shape of the distinguished color of the seal 70 can be easily specified. The seal 70 attached to the container is attached by, for example, a store clerk.

The specific information preliminarily defines the shape and color of the seal corresponding to the quantity sale product and the number sale product, and stores them in association with each other. A seal 70 indicating specific information is affixed to the container 75. Based on the shape of the seal 70 imaged by the imaging unit or the color of the seal 70, the control unit determines whether the product is sold by quantity or sold by number.
In this way, even if the container for the quantity sale product and the container for the number sale product have the same shape and area, the control unit is based on the shape and color of the seal 70 as the specific information imaged by the imaging unit. It is possible to easily discriminate whether the container is a container for measuring goods or a container for selling goods. In addition, when the code information (for example, one-dimensional code or two-dimensional code) specifying the sales form is printed, it is printed on the label attached to the container of the image data captured by the imaging unit. The code information specifying the sales form is decoded to acquire the specific information (acquisition means). In the case of a one-dimensional code, a scanner device (scanner unit) may be used instead of the imaging unit 8 without using the imaging unit 8. Further, the merchandise sales data processing device may be a device in which the imaging unit 8 and the scanner device are combined.

Next, another specific example of the embodiment of the present invention will be described.
The storage means stores, for example, identification information A1 that identifies the container, identification information A2 that identifies the container, identification information A3 that identifies the container, and the like. The specific information A1, A2, A3 is stored in the storage means in association with the information indicating whether the product is sold by quantity or sold by number.

The specification information A1 for specifying the container stores the area of the container, the number of dots corresponding to the area of the container, the shape of the container, and the like.
The specific information A2 for specifying the container stores information on the seal, for example, the shape of the seal and the color of the seal.
The specific information A3 for specifying the container stores, for example, only the color of the seal. In this example, as described above, information relating to the area and shape of the container and information relating to the seal are stored in the storage means as separate files.

Next, an example of a procedure by the control unit to determine whether the container is a product sold by quantity or a product sold in quantity will be described.
(I) First, the area of the container is determined. (II) It is determined whether or not a seal is affixed. (III) When the seal is affixed, after determining the shape of the seal, (IV) determine the color of the seal.
For example, the control unit measures the container and determines whether the product is for sale or for sale.

  It should be noted that the procedure for determining whether the container is a product sold by quantity or a product sold by quantity is not limited to the above-described example. For example, the order (priority order) for determining whether the container is a weighed sale item or a quantity sale item is set by the setting means, and the control unit may make the above determination based on the priority order set by the setting means. Good.

  Next, an example of the priority order set by the setting means is shown.

“Specific information A1 for specifying the container” = the third priority order,
“Specific information A2 for specifying a container” = first priority,
“Specific information A3 for specifying container” = second priority,
“Specific information A4 specifying the container” = fourth priority.

  In this example, based on the specific information A1 that specifies the container, it is the third priority order to determine whether the container is a product for sale or quantity sale based on the area of the container, etc., and the specific information A2 for specifying the container Based on the above, it is the first priority to determine whether a container is sold or sold by the shape of the seal based on the shape of the seal. Based on the specific information A3 for identifying the container, the container is weighed and sold by the color of the seal. Determining whether a product or a product sold in pieces is second in priority order, and code information (for example, a one-dimensional code or a two-dimensional code) that identifies a sales form based on identification information A4 that identifies a container. It is fourth in the priority order to measure the container based on the printed label and to determine whether the product is for sale or for sale.

  In addition, the control unit may determine whether the product is sold by quantity or sold by number based on the combination of the shape and color of the seal based on the captured image data. In this case, even if the number of types of containers is small, the types of product sales forms can be increased by combining the types of containers and the colors and shapes of the seals. For this reason, the inventory quantity and cost of a container can be held down. In the case where the sales form of a product (container) is determined by a label printed with code information (for example, a one-dimensional code or a two-dimensional code) specifying a combination of the color or shape of a seal or a sales form, The location of the sticker or label to be affixed (or pre-printed) on the container is not limited to the upper surface of the container, and may be any of the front and rear surfaces, the left and right surfaces, and the bottom surface of the container. Images are taken from the corresponding directions.

As described above, the merchandise sales data processing apparatus 100 according to the embodiment of the present invention registers the sales data of the articles stored in the container.
Specifically, the merchandise sales data processing apparatus 100 includes an acquisition unit (such as an imaging unit 8 (imaging unit) that images the container) that acquires identification information for identifying the container from the container, and a weighing that measures the mass of the article.

Input and operation errors can be eliminated.

  Further, the control unit 1 of the product sales data processing apparatus 100 uses the container determination unit 101 (container determination unit) to calculate the mass data of the product weighed by the weighing unit 7 when the sales form of the container specified by the container determination unit 101 is the weighing sale. The product registration unit 102 (product registration means) for generating and registering product sales data based on the product data is provided.

  Specifically, the merchandise sales data processing apparatus 100 identifies the container from the imaged data (image data) captured by the imaging unit 8 as to whether the product is a scale sold product or a number sold product, Based on this, it is specified whether the imaged container is sold by weight or sold by number. Then, based on the mass data of the product weighed by the weighing unit 7, it is possible to generate and register the sales data according to the sales form of the specified container according to any of the sale by weight or the quantity sale. . Therefore, it is possible to provide the merchandise sales data processing apparatus 100 capable of generating sales data reliably without the need for an operation input for designating whether the sales form is measured or sold by the operator. In addition, as described above, it is possible to provide the product sales data processing apparatus 100 that can achieve the effects according to the present invention with a simple structure.

  In addition, the storage unit such as the RAM 3 stores a container for storing the article and information (sales form) indicating whether the container is sold by weight or sold in pieces. At the time of setting, information indicating the sales form corresponding to the container type is stored in the storage unit in association with the number of container types in advance, so that they can be easily set, and there are few setting errors.

Further, in the embodiment of the present invention, when the container determination unit 101 is not able to specify the container of the product imaged by the imaging unit 8 in the container specifying process for storing the article, the storage unit such as the RAM 3 is provided. The merchandise sales data processing apparatus 100 includes a display unit 6 that displays one or more containers to be stored as candidates.
That is, when the container cannot be determined by the container determination unit, the display unit 6 (display unit) that displays the container stored in the storage unit such as the RAM 3 as the storage unit as a candidate is displayed on the commodity sales data processing device. 100 has.
That is, even if the container cannot be recognized from the imaged data (image data) of the product imaged by the imaging unit 8, the control unit 1 displays a plurality of container type candidates on the display unit 6 in a selectable manner. The product registration unit 102 can reliably generate and register product sales data based on information indicating the type of container selected and input by the operator among the plurality of candidates.
In the process in which the control unit 1 displays a plurality of container type candidates on the display unit 6 in a selectable manner, the order in which the container type candidates to be displayed are displayed is the imaging data of the products imaged by the imaging unit 8. You may make it display on the display part 6 so that the container close | similar to the container recognized based on (image data) can be selected in order.

  Moreover, in embodiment of this invention, the container information storage part 32 memorize | stores the mass data of a container. The merchandise registration unit 102 subtracts the mass data of the container from the mass data of the merchandise weighed by the weighing unit 7, and generates and registers sales data of the article based on the subtracted value. Therefore, it is possible to provide the product sales data processing apparatus 100 that can appropriately generate and register sales data such as the number of articles contained in the product and the sales price.

  In the present embodiment, the storage unit such as the RAM 3 includes specific information for identifying the container, identification information for identifying the article contained in the container, unit mass data of the article, and the unit price of the article contained in the container. Are stored in association with each other. The product registration unit 102 (product registration unit) is weighed when the determined container is a product sold by weighing based on the specific information that identifies the container determined by the container determination unit 101 (container determination unit). The product sales data is generated based on the mass data obtained by subtracting the mass data of the container from the mass data of the product and the unit price of the product. If the determined container is not a product sold by scale, the mass data of the measured product The number of articles is calculated based on the mass data obtained by subtracting the container mass data and the unit mass data of the article, and sales data of the article is generated based on the calculated number and the unit price of the article. For this reason, optimal sales data can be generated according to the sales form without the operator performing complicated operations.

  In the embodiment of the present invention, whether the product is properly placed in the product recognition range 61 a by the imaging unit 8 is determined by the imaging data (image data) generated by the imaging unit 8. When it is determined that the product is not properly placed in the recognition range 61a, error processing is performed. For this reason, it is possible to provide the merchandise sales data processing apparatus 100 that allows the operator to place the merchandise within the recognition range 61a by the imaging unit 8 and identify the container of the merchandise.

  Moreover, in this embodiment, each pixel of the imaging data (image data) imaged by the imaging unit 8 is binarized, and the container and the background portion other than the container are clearly separated, so that the area and shape of the container Etc. can be easily identified. The area of the container and the type of container are stored in advance in a storage unit such as the RAM 3. The control unit 1 can obtain the area of the container placed on the measuring unit 7 by binarizing the imaged data (image data) of the product imaged by the imaging unit 8. The type of the container stored in the storage unit can be easily specified based on the above.

In addition, depending on the installation location of the device (environment in which room illuminance changes due to external light), it is assumed that the room illuminance changes due to weather, time zones such as morning, noon, and night, indoor lighting, etc. The values of the brightness, gamma, color, etc. of each pixel of the image data (image data) imaged by the imaging unit 8 change greatly. In this embodiment, as calibration, a mounting surface (the color of the mounting surface is a single color) is imaged without placing any container or the like, and the brightness, gamma, and color of the captured image (imaging) data Are adjusted (corrected), and the corrected (adjusted) values of brightness, gamma, color, etc. are set as threshold values for the binarization process. Thereby, it is possible to reliably identify the container from the image data captured by the imaging unit 8 in a state where the container is mounted on the mounting surface. Note that correction values such as lens distortion may be stored in addition to calibration.
Specifically, for example, the mounting surface is imaged by the imaging unit 8 for each time period, a threshold value for binarization processing is defined based on the image data, and stored in the storage unit. The control unit 1 performs binarization processing on the image data captured by the imaging unit 8 using the threshold value of the binarization processing for each time period stored in the storage unit, specifies the area of the container, The type of the container can be reliably identified from the area of the container. In addition, when storing in the storage unit, the value (calibration threshold value) calibrated for each time zone in the morning, noon, and night (the threshold value of the binarization process) and the switching time of the use time zone in the morning, noon, and night And automatically calibrated values (binarization processing threshold) for each time zone based on the time measured based on the time measuring means and the switching time. You may make it switch. Further, an illuminometer or the like may be provided in the apparatus, and a calibrated value (a threshold value for binarization processing) may be automatically switched based on a value indicated by the illuminometer.
