Abstract

The invention relates to a positioning and navigation system and a positioning and navigation method of an intelligent shopping cart for a shopping mall. The system comprises the intelligent shopping cart, a positioning module and a main controller, wherein a steering motor, a driving motor, a steering motor controller, a driving motor controller, an ultrasonic radar and a sound warning indicator are mounted on the intelligent shopping cart; and the main controller comprises an image information processor, a starting and ending point input module, a structured map, a path following module and a path planning module, the positioning module adopts a global camera, and Zigbee communication modules are mounted in the main controller, each intelligent shopping cart and each vertical ladder and each escalator in the shopping mall and are used for transmitting and receiving signals. The system adopts a global camera to monitor the intelligent shopping cart on each layer in all directions and accurately confirm the position of the intelligent shopping cart, the positioning and navigation mode is novel, the function of cross-layer work of the intelligent shopping cart is achieved, and the efficient positioning function can be provided in indoor and partial outdoor environments.

Description

technical field [0001] The invention relates to the technical field of smart shopping carts, in particular to a positioning and navigation system and a positioning and navigation method for smart shopping carts used in shopping malls. Background technique [0002] With the development of artificial intelligence technology, more and more smart shopping carts have appeared on the market. The existing smart shopping cart can automatically follow customers to facilitate shopping; it can also guide customers to the location of the products they need to avoid customers getting lost; it can also check the preset shopping list with the purchased products to remind customers, Avoid missed purchases, and you can also checkout automatically. [0003] The smart shopping cart can successfully complete the above tasks mainly based on the positioning and navigation system. However, most of the positioning and navigation systems of mobile smart shopping carts are based on GPS and Beidou s...
