Problems solved by technology

However, this method still has shortcomings: first, when the user wears gloves or the hands are covered by clothing, it cannot be correctly identified; second, it is easy to mistakenly identify the product that the customer brings as the product for sale
[0005] In addition to the above-mentioned methods, the main reason for the low recognition accuracy of various existing product recognition methods is that the state of the product may change greatly during the process of being picked and placed, such as the angle or distance between the product and the camera. When changing, the area, length, width and height of the product will change greatly, which will lead to the failure of recognition

Embodiment 1

[0034] The commodity pick-and-place recognition device in this embodiment is a processor connected to the intelligent vending cabinet in communication. Among them, there are multiple products for sale stored in the smart vending cabinet, which can be photographed by the camera when the user opens the cabinet door and picks up and places the products for sale, and sends the captured pick-and-place video to the product picker after the user closes the cabinet door. Put the identification device.

[0035] figure 1 It is a block diagram of the device for constructing user portraits in Embodiment 1 of the present invention.

[0036] Such as figure 1 As shown, the commodity pick-and-place recognition device 100 is connected to a smart vending cabinet 200 in communication, and is used to identify the pick-and-place video sent by the smart vending cabinet 200 so as to identify the items to be taken out or put into the smart vending cabinet 200 by the user. sell goods. The commodit...

Embodiment 2

[0091] In the second embodiment, the components having the same structure as those in the first embodiment are given the same symbols and corresponding explanations are omitted.

[0092] Compared with Embodiment 1, this Embodiment 2 is for more effective identification when the length and width of some products are not much different (such as beverages, instant noodles and other products with similar length and width). The difference lies in the outline The judging part realizes judging the correspondence between contours in another way, specifically:

Abstract

The invention provides a commodity pick-and-place recognition device and a commodity pick-and-place recognition method, which are used for recognizing a pick-and-place video shot when a user picks and places a commodity to be sold in an intelligent vending cabinet, and are characterized in that the commodity pick-and-place recognition device comprises a commodity analysis part, an recognition part and a display part, analyzing the outline and corresponding position information of each commodity contained in each frame image from the frame images of the pick-and-place video; the contour judging part is used for judging a corresponding relation between contours in each frame image according to a preset contour deformation range judging rule, a preset position information moving range judging rule and the contour and position information of each commodity contained in two adjacent frame images, and judging the corresponding relation between the contours in each frame image; the commodities corresponding to the contours with the corresponding relation are used as the same to-be-sold commodity; the moving track forming part is used for connecting the position information of the same commodity to be sold in each frame image to form a commodity moving track; and the pick-and-place judging part is used for judging whether the to-be-sold commodity is picked and placed by the user at least according to the commodity moving track.

Description

technical field [0001] The invention belongs to the field of intelligent vending, and relates to an intelligent vending cabinet, in particular to a commodity pick-and-place recognition device and method. Background technique [0002] Smart vending cabinets are commonly used equipment for commercial automation. They can be placed in shopping malls, supermarkets, etc. to provide retail services for users. The dynamic image cabinet is a common smart vending cabinet, which can identify the goods taken out by the user by shooting video with the camera. It has the characteristics of low production and maintenance costs, and high utilization of internal space. [0003] However, there are still many deficiencies in the current dynamic image cabinets on the market. The main problem is that the recognition accuracy is low, and it is difficult to accurately judge whether the product identified in the video frame is indeed a product for sale that is picked up by the user, so it is easy ...
