Monitoring method, device and system for goods of intelligent sales container

Abstract

The invention relates to the field of intelligent sale, and especially relates to a monitoring method, device and system for goods of an intelligent sales container. The method includes the followingsteps: acquiring gravity change data of the goods in the intelligent sales container and image data of the goods before and after a gravity change; determining a set of hypothetical change conditionsof varieties and quantity of the goods according to the gravity change data; determining a difference in a category and the quantity of the goods before and after the gravity change according to the image data; and determining an actual change condition of the goods according to the set of the hypothetical change conditions and the difference in the category and the quantity of the goods. The monitoring method, device and system combine gravity and image analysis, overcome the defects that an existing algorithm cannot distinguish the goods with similar weight and similar appearance at the sametime, enable the accuracy rate of recognition of the goods by the intelligent sales container to be improved, further enrich types of the goods applicable to the intelligent sales container, and canmeet needs of different groups of people.

Description

technical field [0001] The present invention relates to the field of intelligent vending, in particular to a method, device and system for monitoring goods in an intelligent vending cabinet. Background technique [0002] In recent years, the emergence of smart vending cabinets has greatly facilitated customers. Without the direct participation of the sales staff, the customer selects the desired product, and after paying by inserting coins or scanning the QR code, the smart vending cabinet automatically provides the corresponding product to the customer. [0003] Smart vending cabinets need to monitor the sales of goods so that merchants can replenish corresponding goods in time. There are usually two methods for commodity monitoring in existing smart vending cabinets. One is to use a gravity sensor to monitor changes in the gravity of the commodity, thereby deriving changes in the variety and quantity of the commodity. The image of the commodity, through the comparison of...

AI Technical Summary

Problems solved by technology

[0004] However, the smart vending cabinet using the gravity sensor has high requirements on the weight of the product, requiring a significant difference in the weight of different types of products, such as not being able to support two beverages of 500ml

Smart vending cabinets using visual sensors (cameras) require significant differences in the appearance of the products, such as not being able to support beverages with white lids; at the same time, it is required that the products cannot block each other, such as not being able to support soft-packaged products placed at an angle

It can be seen that the existing monitoring methods for intelligent vending cabinets restrict the diversification of commodities sold and cannot meet people's needs
