Information processing method, information processing device, and recording medium

Abstract

An information processing method according to an aspect of the present disclosure includes: acquiring, from a video, flow line information of a customer; detecting that the customer acquires an item; and storing, in a storage, flow line information of the customer and information on a number of items acquired by the customer, in association with each other.

1 . An information processing method, comprising:
 acquiring, from a video, a plurality of time-series positions of a customer;   detecting a number of items acquired by the customer at each of the plurality of time-series positions;   storing, in a storage device, flow line information including the plurality of time-series positions and the number of items corresponding to each of the plurality of time-series positions;   when the customer is within a predetermined area, identifying, the flow line information of the customer stored in the storage device;   determining, by referring to the storage device, the number of items corresponding to the identified flow line information; and   comparing the determined number of items and a number of items paid for by the customer at a register.   
     
     
         2 . The information processing method according to  claim 1 , further comprising:
 detecting, as an anomaly, that there is a discordance between the determined number of items and the number of items paid for.   
     
     
         3 . The information processing method according to  claim 1 , further comprising:
 notifying, based on the comparing, that an anomaly is detected.   
     
     
         4 . The information processing method according to  claim 1 , wherein the predetermined area is an area in front of the register where the customer lines up to pay. 
     
     
         5 . The information processing method according to  claim 1 , further comprising:
 when the customer goes out of the predetermined area, detecting, as an anomaly, that the determined number of items is one or more.   
     
     
         6 . The information processing method according to  claim 1 , further comprising:
 when the customer crosses a predetermined line, detecting, as an anomaly, that the determined number of items is one or more.   
     
     
         7 . An information processing device, comprising:
 at least one memory configured to store instructions; and   at least one processor configured to execute the instructions to:
 acquire, from a video, a plurality of time-series positions of a customer; 
 detect a number of items acquired by the customer at each of the plurality of time-series positions; 
 store, in a storage device, flow line information including the plurality of time-series positions and the number of items corresponding to each of the plurality of time-series positions; 
 when the customer is within a predetermined area, identify, the flow line information of the customer stored in the storage device; 
 determine, by referring to the storage device, the number of items corresponding to the identified flow line information; and 
 comparing the determined number of items and a number of items paid for by the customer at a register. 
   
     
     
         8 . A non-transitory recording medium storing a program for causing a computer to execute:
 acquiring, from a video, a plurality of time-series positions of a customer;   detecting a number of items acquired by the customer at each of the plurality of time-series positions;   storing, in a storage device, flow line information including the plurality of time-series positions and the number of items corresponding to each of the plurality of time-series positions;   when the customer is within a predetermined area, identifying, the flow line information of the customer stored in the storage device;   determining, by referring to the storage device, the number of items corresponding to the identified flow line information; and   comparing the determined number of items and a number of items paid for by the customer at a register.
