Abstract

The invention relates to a positioning and navigation system and a positioning and navigation method for an intelligent shopping cart used in a shopping mall. The system includes an intelligent shopping cart, a positioning module, and a main controller. A steering motor, a driving motor, and a steering motor controller are installed on the intelligent shopping cart , drive motor controller, ultrasonic radar and sound alarm; the main controller includes an image information processor, start and end point input module, structured map, path following module, path planning module, and the positioning module uses a global camera. Each smart shopping cart, each elevator and each escalator in the mall are equipped with Zigbee communication modules for signal transmission and reception; the system uses a global camera to monitor the smart shopping carts on each floor in all directions and accurately The location of the smart shopping cart, the positioning and navigation method is novel, realizes the function of the smart shopping cart working across layers, and can provide efficient positioning functions in indoor and some 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...
