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.
