Image recognition system, image recognition method, and storage medium

Abstract

Provided is an image recognition system that can easily perform image recognition on a side face of an item. An image recognition system according to one example embodiment of the present invention includes: a placement stage used for placing an item below an image capture device provided so as to perform capturing of a downward direction; a support structure configured to support the item at a predetermined angle relative to a top face of the placement stage; and an image recognition apparatus that identifies the item by performing image recognition on an image of the item acquired by the image capture device.

1 . An image recognition system comprising:
 a placement stage used for placing an item below an image capture device provided so as to perform capturing of a downward direction;   a support structure comprising a first surface inclined at a predetermined angle with respect to a top face of the placement stage, and a second surface perpendicular to the first surface; and   an image recognition apparatus configured to identify the item by performing image recognition on an image of the item acquired by the image capture device.   
     
     
         2 . The image recognition system according to  claim 1 , wherein the support structure comprises a protrusion portion that partitions the first surface into at least two regions. 
     
     
         3 . The image recognition system according to  claim 1 , wherein the image recognition apparatus is configured to correct the image by using the angle and perform the image recognition on the corrected image. 
     
     
         4 . The image recognition system according to  claim 1 , wherein the image recognition apparatus is configured to correct the image by using positional relationship between the image capture device and the support structure and perform the image recognition on the corrected image. 
     
     
         5 . The image recognition system according to  claim 1 ,
 wherein the image recognition apparatus is configured to perform the image recognition on a predetermined recognition region on the placement stage, and   wherein the support structure is provided in contact with an end of the recognition region or near the end of the recognition region.   
     
     
         6 . The image recognition system according to  claim 5 , wherein the support structure is provided at a position closer to the end of the recognition region than to a midpoint of a line between a point at which an optical axis of the image capture device intersects the recognition region and the end of the recognition region. 
     
     
         7 . The image recognition system according to  claim 6 , wherein the support structure is provided at a position closer to the end of the recognition region than to a point closer to the end of the recognition region out of trisection points of a line between a point at which an optical axis of the image capture device intersects the recognition region, and the end of the recognition region. 
     
     
         8 . The image recognition system according to  claim 1 , wherein the angle is greater than 0 degree and less than 90 degrees. 
     
     
         9 . The image recognition system according to  claim 1 , wherein the angle is greater than or equal to 30 degrees and less than or equal to 60 degrees. 
     
     
         10 . An image recognition method with an image recognition system comprising:
 a placement stage used for placing an item below an image capture device provided so as to perform capturing of a downward direction; and   a support structure comprising a first surface inclined at a predetermined angle with respect to a top face of the placement stage, and a second surface perpendicular to the first surface, the image recognition method comprising:   identifying the item by performing image recognition on an image of the item acquired by the image capture device.   
     
     
         11 . A non-transitory storage medium storing a program that causes a computer to perform, with an image recognition system comprising:
 a placement stage used for placing an item below an image capture device provided so as to perform capturing of a downward direction; and   a support structure comprising a first surface inclined at a predetermined angle with respect to a top face of the placement stage, and a second surface perpendicular to the first surface,   identifying the item by performing image recognition on an image of the item acquired by the image capture device.
