Monitoring system and monitoring method for supermarket shopping cart

Abstract

The invention relates to a monitoring system and monitoring method for a supermarket shopping cart. The monitoring system comprises a controller mounted between shopping cart handles, a code scanner, a weighing sensor arranged at the bottom of a basket and a camera positioned at the upper end of the basket and used for monitoring a basket opening; the code scanner is positioned at the lower side of the controller and is opposite to the basket opening of the shopping cart; the code scanner, the weighing sensor and the camera are respectively in communication connection with the controller; the complete shopping process of a customer is divided into six states; in each state, weight change information fed back in real time by the weighing sensor, information of each frame of image, which is acquired by a monitoring device, and commodity information acquired by the code scanner are utilized to different degrees; and by combining a plurality of image analysis algorithms, an anti-theft function of an intelligent shopping cart system in the shopping process is achieved. By carrying out gray scale image statistic characteristic analysis or mode identification on a detected motion target image or a skin color detection image, empty-handed or commodity-held detection in a monitoring region is implemented, and a violation operation of the customer is timely reminded and corrected.

Description

technical field [0001] The invention relates to a supermarket shopping cart monitoring system and a monitoring method thereof, in particular to a supermarket shopping system based on the combination of image analysis and gravity sensing and a monitoring method thereof. Background technique [0002] Although online shopping is very convenient nowadays, supermarket shopping is still an important shopping channel and way of life for people. Especially in first- and second-tier cities or holidays, the phenomenon of queuing for payment is prominent, which makes the originally fast shopping method lag behind due to the long time of waiting in line for checkout. Excellent shopping experience reduces customers' consumption desire, but increases the operating cost of supermarkets. Therefore, the research and development of an intelligent shopping system integrating self-service code scanning checkout and real-time monitoring of theft has broad market prospects and great commercial va...

AI Technical Summary

Problems solved by technology

[0003] There have been many similar studies at home and abroad. Wal-Mart first developed RFID technology in the retail industry, and developed an RFID-based smart shopping cart and tried it in some Wal-Mart supermarkets. Then Dalian University of Technology and Shanghai Jiaotong University studied RFID-based shopping. Smart terminals, this research uses RFID tags to replace multi-dimensional barcodes. The tags not only contain various information of commodities, but also have good anti-counterfeiting technology, encryption technology and information control. However, RFID tags cannot replace ordinary two-dimensional barcodes for a long time. Code, so now only a few Wal-Mart supermarkets are promoting the application

In addition, Central South University, School of Information Science and Engineering, and University of Electronic Science and Technology of China have studied smart shopping carts based on embedded systems. This solution combines ordinary barcodes and smart terminals with embedded operating systems to realize indoor navigation, barcode scanning, Manage shopping lists, generate payment codes, etc., but this solution does not involve the anti-theft function of the shopping cart, so it cannot be widely used

However, Liu Bing and others from Northeast Forestry University used the electronic product anti-theft system (EAS system) to prevent theft of shopping cart products. Using the soft label of each product, the EAS system can be used to decode the soft label after the product is settled, so as to achieve anti-theft , which is similar to RFID tags, it is necessary to make different soft tags for each product, the workload is large, and it cannot be widely used

At present, some anti-theft measures in supermarkets are basically on the electronic gate of the supermarket door, including patent CN201520043135.6 and patent CN201510559549.9. The logical judgment of this method is too simple, and it cannot detect the operation of sneaking goods in the shopping process.
