Embodiment 1

[0043] See attached figure 1 Said, a dynamic vision-based unmanned vending method, applied to unmanned vending cabinets, the method includes:

[0044] S100: Detect the state of the unmanned vending cabinet door, and create a shopping cart list when the unmanned vending cabinet door is in an open state;

[0045] S200: Perform biometric identification on the user's hand, and track the position of the hand when the shape of the user's hand is recognized;

[0046] S300: Set the shopping area in advance. When it is detected that the hand position information is in the shopping area, create a temporary product list and a temporary position list, store the product information detected by the user's hand in the temporary product list, and store the detected The location information of the product is added to the temporary location list;

[0047] S400: When it is detected that the hand position information is not in the shopping area, analyze the movement direction of the hand accord...

Embodiment 2

[0073] The specific operation steps of a dynamic vision-based unmanned vending method and system are as follows:

[0074] The user binds the identity information, and the cabinet door can be opened after the binding is successful.

[0075] Step 1: Real-time detection of the state of the unmanned vending cabinet door through the automatic wake-up module. When the unmanned vending cabinet door is open, a shopping cart list is created and the camera device is turned on.

[0076] Step 2: The tracking module uses the target detection algorithm to perform biometric identification on the user's hand, and detects whether the user's hand appears in the current camera picture frame by frame. If no hand is detected in the current picture, the target detection algorithm continues to read the video stream Perform loop detection; if a hand is detected in the current screen, the tracking module assigns a tracker to the currently detected hand, and then the tracker is responsible for maintain...

Abstract

The invention discloses an unmanned vending method and system based on dynamic vision, and belongs to the technical field of artificial intelligence. The method comprises the following steps: detecting the state of an unmanned vending cabinet door; performing biological recognition on the hand of the user; judging the movement direction of the hand relative to the self-service vending cabinet door; judging a shopping state according to the movement direction, the temporary commodity list information and the updated temporary shopping cart information; and obtaining a final shopping result, and completing shopping. According to the invention, the accuracy of commodity identification is improved, the commodity damage rate is reduced, and the shopping experience is improved.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, and more specifically relates to a dynamic vision-based unmanned vending method and system. Background technique [0002] At present, with the rapid development of artificial intelligence, more and more industries have begun to use artificial intelligence, and the application range of unmanned vending machines is becoming wider and wider. Traditional unmanned vending cabinets are mainly divided into closed containers with touch screens and weighing containers. The working logic of the touch screen unmanned vending cabinet is that the user first selects the product, and after payment, the system transmits the product to the outlet through the motor drive to complete the shopping; the working logic of the weighing unmanned vending cabinet is in the container. A gravity sensor is installed on each floor, and the price of the product is estimated by the value change of the se...
