Canteen payment system and method based on image recognition technology

Abstract

The invention discloses a canteen payment system and a method based on an image recognition technology. The canteen payment system comprises a camera, a pressure sensor, a host, a card swiping machine and a displayer, wherein the camera, the pressure sensor, the credit card machine and the displayer are all connected with the host. The canteen payment method comprises the following steps: taking out a dish sample from a sample database after the whole image data is obtained and traversing the whole image data, when the similarity of a certain dish image data in the whole image data and the dish sample data is larger than 80%, determining that the current traversal dish is the same with the dish sample, the host calling successfully matched dish information which is corresponding to the dish sample from the sample database by the host and outputting the dish information and the total number of dishes to the displayer and storing the dish information and total value of the dish into a consumption database; and calculating and outputting the total price of the dishes after all the dishes in the whole image are identified, and reminding a consumer by the displayer to pay the amount of consumption through the credit card machine.

Description

technical field [0001] The invention relates to a canteen payment system and method based on image recognition technology, in particular to a canteen payment system and method for calculating the price of the dishes by identifying the plates containing the dishes, judging the information of the dishes purchased by consumers, and calculating the price of the dishes. Background technique [0002] Many government agencies and colleges and universities have set up their own cafeterias to solve the dietary problems of on-the-job employees. On the sales side, the current mainstream method is self-service selection and credit card settlement. As a relatively advanced settlement method, the IC card settlement system has been established. It is widely used in various occasions that require fast settlement. Compared with the most primitive meal ticket system, it has been greatly improved. However, with the continuous development of consumption levels, the variety of dishes in canteens...

AI Technical Summary

Problems solved by technology

However, with the continuous development of consumption levels, the variety of dishes in canteens is also increasing, and the flow of people in consumption places is also increasing. This has brought great pressure to the billing terminal, and there is a long queue at the check-in counter during the peak consumption period. became a common phenomenon

The puncher not only needs to identify a variety of dishes and their prices at the IC card swipe place, but also calculates the superposition. There is no effective way to guarantee the speed and accuracy. We can only hope for the proficiency and responsibility of the operator.

[0003] The automatic settlement method in the form of RFID requires induction chips to be installed on the dinner plate. For fragile dinner plates, the transformation cost is huge and it is not suitable for promotion

[0004] At the same time, in the existing technology, the massive information in the transaction process is not collected and utilized, and only the consumption price can be counted for each person, but the specific consumption content cannot be counted. This cannot but be said to be a huge waste of resources and manpower
