Description

This invention relates to an article identification system, article identification device, and program for simultaneously identifying information on multiple articles. A device capable of simultaneously recognizing information on multiple products is known. The product registration device described in Patent Document 1 can recognize multiple products at once by photographing multiple products on a tray and simultaneously reading the barcodes of the products in the captured images. Japanese Patent Publication No. 2016-177433 This is a perspective view showing the external appearance of the item identification system 1.This block diagram shows the electrical configuration of an item identification system.This is an example of the display of the item identification screen 50.This is a conceptual diagram of product information database 60.This is a flowchart for the item identification process.This is a continuation of the flowchart for item identification processing.This is an example of the initial display state of the item identification screen 50.This is an example of how to display a marker on the item identification screen 50.This is an example of how the product name is displayed on the item identification screen 50.This is an example of how the marker and product name are displayed on the item identification screen 50 when items are placed on top of each other and the AR object is not extracted. Referring to the drawings, an item identification system 1 according to one embodiment of the present invention will be described. The item identification system 1 is a system that photographs multiple items, each equipped with an identification code, and displays the number of codes extracted from the photographed images, allowing an operator to easily verify the number of items. The item identification system 1 is used, for example, in a store that sells items as merchandise, as a system for identifying multiple items at once during checkout. As shown in Figure 1, the item identification system 1 comprises a shooting table 2, a shooting device 3, and an identification terminal 4. The shooting table 2 is a platform that indicates the position for placing multiple items to be photographed. In this embodiment, a tray 25 for holding multiple items is prepared, and by placing the tray 25 on the shooting table 2, all items on the tray 25 are placed within the shooting range P. Each item is individually packaged in a transparent bag, and a label sticker 26 with the product name and a different code for each type of product is attached beforehand. The code is, for example, an AR marker. The imaging device 3 is a device that photographs a preset shooting range P on the shooting table 2 from above the shooting table 2. The imaging device 3 has a columnar portion fixed to the side of the shooting table 2 and extending upward, an arm-shaped portion extending upward towards the center of the shooting table 2 from the upper part of the columnar portion, and an imaging unit 31 provided at the lower part of the arm-shaped portion, which directs the shooting direction toward the shooting table 2 located below. The imaging unit 31 is pre-adjusted in terms of shooting direction and field of view to photograph the shooting range P of the shooting table 2, and is assembled to the imaging device 3. The identification terminal 4 is, for example, a well-known tablet terminal. The identification terminal 4 connects to the camera 3 using a known USB cable 35 and acquires captured images or video footage of the shooting range P captured by the camera 3. In the following description, if there is no particular distinction between still images and video footage, they will be referred to as "captured images." As will be described in detail later, the identification terminal 4 accepts input from the operator and displays on the screen the captured images taken by the camera 3, the number of codes extracted from the captured images, a list of product information corresponding to the codes, etc. The identification terminal 4 may be used as a terminal device for a point-of-sale (POS) system (not shown), or it may be used in connection with a cash register (not shown). Referring to Figure 2, the electrical configuration of the item identification system 1 will be described. The imaging device 3 has an imaging unit 31 and a control unit 32. The imaging unit 31 is a known CCD image sensor or CMOS image sensor. The control unit 32 processes the data output from the imaging unit 31 to generate image data of the captured image and outputs it to the identification terminal 4. When outputting captured video, the control unit 32 continuously generates image data according to the frame rate and outputs it as video data to the identification terminal 4. The identification terminal 4 comprises a control unit 41, a storage unit 42, a touch panel 43, and a USB interface 46. The control unit 41 includes a known CPU, ROM, and RAM (not shown). The CPU controls
