Abstract

The invention discloses a product identification method and a system for an unmanned vending machine. The method comprises the following steps of: taking a pre-purchase product image of all the products currently being sold before a consumer purchases; analyzing the types and the quantities of all the products in the unmanned vending machine before the purchase by image recognition; then comparingwith a purchased product image after the purchase,; and analyzing the missing products after the purchase by the image recognition to obtain the types and the quantities of the products purchased this time. Therefore, the sales of a wide range of the products can be realized. According to the method and the system provided by the invention, multiple products can be detected and identified at onetime, and the consumer can conveniently purchase multiple products at one time. Therefore, the rapid and effective identification of the purchased products can be realized, so that checkout is carriedout quickly, thus the consumer can conveniently select and purchase multiple products at one time, and the sales efficiency of the unmanned vending machine is improved.

Description

technical field [0001] The invention relates to the technical field of item image recognition in a miniature unmanned vending system, in particular to a method and system for identifying items in an unmanned vending machine. Background technique [0002] A vending machine is a machine that can automatically sell goods by inserting coins or paying by other payment methods. Vending machine is a common part of modern retail automation. It is not limited by time and place, can save manpower and material resources, and facilitate transactions. It is a new form of commercial retail. With the improvement of social productivity and the improvement of people's living consumption level, the existing consumption pattern can no longer meet people's daily needs, so there is an urgent need for new shopping distribution channels. Traditional retail stores such as supermarkets and shopping malls require a lot of manpower, material and financial resources, and operators are already at a los...
