Unmanned vending system based on pressure sensing and vision fusion

Abstract

The invention discloses an unmanned sales system based on pressure sensing and visual fusion. By adopting the pressure sensors, the gravity data in each bearing box in a cabinet body can be monitoredin real time, on one hand, the commodity quality and quantity selected by a customer can be judged and recognized according to gravity data changes obtained by all the pressure sensors, and on the other hand, the shopping behavior of the customer can be judged according to the pressure changes in each bearing box. Meanwhile, the camera is used for collecting the picture information of the commodities selected by the client, and the commodity selection of the client can be judged through a commodity recognition module based on vision. Compared with the prior art, the three recognition processesof the present invention are perfectly fused, so that the commodity recognition accuracy is greatly improved. The system focuses on pressure identification, is fast in identification speed and high in efficiency, is visual identification-assisted, enables the accuracy and the safety coefficient to be improved, takes the shopping behavior identification as a supplement means to enhance the identification accuracy and the safety coefficient, does not need labeling, and is simple in manufacturing process and low in cost.

Description

technical field [0001] The invention relates to the technical field of automatic vending, and more particularly, relates to an unmanned vending system based on pressure sensing and visual fusion. Background technique [0002] The current unmanned vending cabinets are as follows: [0003] The first is the RFID-based unmanned vending cabinet. The basic principle of this unmanned vending cabinet is to add RFID radio frequency tags to the goods, and configure the radio frequency reading device in the vending machine to recognize the RFID tags when customers take the goods. Separate purchased items. [0004] The second is an unmanned vending cabinet based on visual recognition technology. This technology collects pictures through 24-hour uninterrupted cameras, and then analyzes the products purchased by customers from the pictures. [0005] The third is an unmanned vending cabinet based on gravity sensing to identify products. This technology uses pressure sensors to sense the ...
