Automatic restaurant settlement method and system

Abstract

The invention relates to an automatic restaurant settlement method and system. The method includes the steps that a whole image in a detected area is shot, and the whole image contour is extracted through an image processing method; whether tray and service plate images exist in the detected area is judged through an image recognition technology by using the contour information, and the whole image and the contour information are stored; then the contour and tone information of service plates is extracted through the graphics and the image processing method; the contour and tone information of the service plates is matched with template information in a database to obtain the contour shapes and colors of the service plates; the total amount of dishes is obtained through the relevance of the shapes and the colors of the service plates and the prices of the dishes. The system comprises a camera, a computer, a machine point of sale machine (POS) and a display. According to the automatic restaurant settlement method and system, the service plates do not need to be customized or transformed, the automatic restaurant settlement method and system are suitable for the service plates of any shape and material, the cost is low, high efficiency and rapidness are achieved, certain robustness is achieved to the overlapping and blocking of the service plates, and no special requests for the service plate placing mode of repast personnel are needed.

Description

technical field [0001] The invention relates to an automatic settlement technology in the catering field, in particular to an automatic settlement method and system for a restaurant. Background technique [0002] In recent years, many government agencies, universities and other institutions have solved the dining problem of employees or students by running their own restaurants. At present, the mainstream method is to choose independently and pay by credit card. However, due to the increase of diners, this puts a lot of pressure on the billing terminal. On the one hand, the slow settlement speed often leads to queuing during the peak consumption period; on the other hand, the accuracy of price calculation is difficult to be guaranteed. [0003] In response to the problems of traditional manual settlement methods, some automatic settlement systems have been proposed, mainly as follows: [0004] (1) Settlement method based on barcode recognition [0005] Each plate is attach...

Problems solved by technology

However, some of these methods are currently based solely on image color information, which is easily affected by factors such as light; some are based on the outline area and perimeter of the dinner plate for shape recognition, which puts restrictions on the shape of the dinner plate; at the same time, the above method is only applicable to the dinner plate In the case where there is no occlusion between the plates, the robustness to overlapping and occlusion between the plates is very poor, and the above method uses hardware equipment such as a tray detection device or a pressure sensor when collecting images of the plates and trays, and the cost is relatively high. The system is more complex
