Commodity change detection method, device and equipment for unmanned vending cabinet and storage medium

Abstract

The embodiment of the invention provides a commodity change detection method and device for an unmanned vending cabinet, equipment and a storage medium. The method comprises the following steps: acquiring an image of a commodity in an initial container when the door of the unmanned vending cabinet is opened; if it is detected that the hand or the clamping tool of the user extends out of the unmanned vending cabinet, obtaining an image of a commodity in a target vending cabinet when the hand or the clamping tool of the user extends out of the unmanned vending cabinet; according to the commodity image in the target container and the commodity image in the initial container obtained for the first time, determining commodity change information of first commodity change, and according to the commodity image in the target container obtained for the Nth time and the commodity image in the target container obtained for the (N-1) th time, determining commodity change information of Nth commodity change, wherein N is larger than or equal to 2; according to the commodity change information determined each time, determining the commodity change condition of the unmanned vending cabinet in the period from door opening to door closing. In this way, the difficulty that the commodities are uniformly detected after being changed for multiple times can be avoided, and the accuracy of commodity change detection is improved.

Description

technical field [0001] The present disclosure relates to the field of unmanned vending cabinets, and in particular to a commodity change detection method, device, equipment and storage medium for unmanned vending cabinets. Background technique [0002] In recent years, with the development of intelligent level, unmanned retail, as a new retail model based on intelligent technology to realize the absence of shopping guides and cashiers, has become a hot spot of attention. As one of the important equipment of the unmanned retail sales model, the unmanned vending cabinet has gradually developed from the traditional closed mechanical container to an open unmanned vending cabinet. [0003] Consumers generally take some commodities from the unmanned vending cabinets according to their needs. The traditional product change detection scheme usually detects the difference between the product images in the container when the door of the unmanned vending container is opened and closed...

AI Technical Summary

Problems solved by technology

However, in some cases, consumers may put their hands in and out of the unmanned vending cabinet many times and move the goods in the unmanned vending cabinet. In this way, the difference in the image of the goods in the container when the door is opened and closed becomes smaller. Large, resulting in low accuracy of commodity change detection
