Intelligent cashier method based on dinner plate recognition

Abstract

The invention relates to an intelligent cashier method based on dinner plate recognition, and the method comprises the steps: collecting dinner plate pictures, dividing the dinner plate pictures intotraining samples and test samples, carrying out the preprocessing, inputting the training samples into a model network for training in batches, inputting the training samples into a test sample set after stabilization, associating a recognition result with a price if the loss rate is lower than a threshold value, and starting the cashier and timing; enabling the cashier spot to collect photos of dinner plates to be cashied, preprocessing the photos to obtain images of one or more dinner plates, inputting the images into a current recognition model network successively, obtaining the total price based on the recognition result and the number of the corresponding dinner plates, and performing payment after the user confirms that there is no error; and uninterruptedly confirming whether the updating time or the updating batch is reached or not. Complex manual settlement is avoided, after dinner plate picture information is collected once and a stable recognition network is obtained through training, the information can be used for a period of time, the settlement efficiency is high, a settlement channel does not need to be additionally arranged, the queuing situation is greatly relieved, the settlement accuracy is high, restaurant management is facilitated, dinner plates do not need to be customized, the operation cost is low, and the error-tolerant rate is high.

Description

technical field [0001] The present invention relates to the technical field of data processing systems or methods specially suitable for administration, commerce, finance, management, supervision or forecasting purposes, in particular to a smart cash register method based on plate recognition. Background technique [0002] As the pace of urban life continues to accelerate, more and more people solve their dietary problems through restaurants. Because of this, canteen-style restaurants and fast food chain stores have successively landed and developed in various cities. These types of restaurant chains generally adopt independent Mode operation of selecting dishes and unified calculation of cash register. [0003] In the prior art, the cash register settlement of canteen-like restaurants and fast food chain stores is mainly completed through manual settlement or chip identification. [0004] For manual settlement, with the acceleration of social development, there are more an...
