no. 1 example

[0027] First, the product information processing device (image recognition device) according to the first embodiment will be described.

[0028] figure 1 A configuration example of the commodity information processing device 1 according to the first embodiment is schematically shown.

[0029] The product information processing device 1 performs settlement processing for the products in the basket 10 . The product information processing device 1 is installed in a store or the like that sells products. The commodity information processing device 1 executes settlement processing for the commodities in the basket 10 when the basket 10 is arranged at a predetermined position. The product information processing device 1 may also be installed as a self-service cash register in which the user performs settlement processing by himself. In addition, the product information processing device 1 may be installed as a normal cash register where a store clerk performs settlement processin...

no. 2 example

[0102] Next, a second embodiment will be described.

[0103] The product information processing device 1 according to the second embodiment differs from the product information processing device 1 according to the first embodiment in that barcode recognition processing is performed on the inconsistency between the first image and the second image. Therefore, the same symbols are assigned to other points, and detailed descriptions are omitted.

[0104] First, the functions realized by the CPU 21 will be described.

[0105] The CPU 21 has a function of specifying a barcode area from the second image in the changed area where the arrangement of the product has been changed, and recognizing the barcode included in the specified barcode area.

[0106] For example, the CPU 21 designates an area in which the first image and the second image do not match as a changed area. For example, the CPU 21 determines a changed area based on similar pixels or different pixels. For example, th...

[0129] Next, a third embodiment will be described.

[0130] The product information processing device 1 according to the third embodiment differs from the one according to the first embodiment in that the recognition processing for recognizing the barcode and the comparison judgment processing for comparing the first image and the second image are performed in parallel. The product information processing device 1 is different. Therefore, the same reference numerals are assigned to other configurations, and detailed descriptions are omitted.

[0131] First, the functions realized by the CPU 21 will be described.

[0132] The CPU 21 has a function of acquiring the second image at predetermined intervals. For example, the CPU 21 acquires the second image every second. For example, the CPU 21 uses the camera 3 to take pictures of the products in the basket 10 at predetermined intervals, and acquires second images. In addition, the CPU 21 may acquire the second image from an ex...

Abstract

The invention discloses an image recognition device, a product information processing device and an image recognition method capable of recognizing an object changed during recognition processing. The image recognition device includes an acquisition unit and a control unit. The acquisition unit acquires an image in which a pattern representing an object is captured. The control unit designates a pattern area from the first image acquired by the acquisition unit, recognizes a pattern included in the designated pattern area, acquires a second image from the acquisition unit, and judges the object in the first image. Whether the arrangement is consistent with the arrangement of the object in the second image, when it is determined that the arrangement of the object in the first image is inconsistent with the arrangement of the object in the second image, Designating a pattern area from the second image, identifying the pattern contained in the designated pattern area.

Description

[0001] This application claims the priority of the Japanese application with the application date of July 13, 2015 and the application number JP2015-139581 and the US application with the application date of December 23, 2014 and the application number US14 / 581,861, and cites the above applications Content. technical field [0002] The invention relates to an image recognition device, a commodity information processing device and an image recognition method. Background technique [0003] An image recognition device that recognizes a product from an image captured by a camera captures an image after placing a product at a predetermined position, and recognizes the product using the captured image. While the image recognition device is executing the recognition process, the user may add or move products. At this time, there is a technical problem that the conventional image recognition device cannot recognize the product after the change. Contents of the invention [0004]...
