Abstract

The invention discloses a positioning and navigation method in a supermarket based on information fusion. The method employs a positioning and navigation system which is composed of electronic shelf labels, wireless relay nodes, a WiFi route and a server. Each of the electronic shelf labels is composed of a display screen and Bluetooth with a microcontroller; each of the wireless relay nodes is composed of Bluetooth with a microcontroller and a WiFi communication module; the server can send price display information of modified goods, coordinates of the positions of electronic shelf labels and the like to the electronic shelf labels through the WiFi route and the wireless relay nodes; and positioning and navigation APP software is installed in a to-be-positioned mobile phone in advance. The positioning and navigation method provided by the invention employs wireless signal strength range finding and pedestrian dead reckoning, employs particle filter algorithm to realize fusion and positioning on the basis of wireless signal strength range finding and pedestrian dead reckoning and sends price display information of modified goods, coordinates of the positions of electronic shelf labels and the like to the electronic shelf labels through the WiFi route and the wireless relay nodes; so the positioning and navigation method has the advantages of small errors, no accumulative errors, stable signals, accurate positioning and navigation and fast goods searching speed, substantially improves goods searching efficiency of customers and is applicable to large-size supermarkets and shopping places.

Description

technical field [0001] The invention relates to an indoor positioning and navigation method, in particular to an information fusion-based positioning and navigation method in a supermarket. Background technique [0002] With the development of the Internet of Things and smart cities, a large number of information services need the support of location information, that is, location-based information services (LBS), and navigation services. Similarly, in large supermarkets and stores, due to the large space and various products, functions such as positioning navigation and product search are required to improve customer experience. [0003] Traditional GPS positioning and navigation is difficult to assume the role of indoor positioning due to poor indoor signal, so indoor positioning and navigation technology needs to be solved urgently. At present, indoor positioning often uses WIFI, RFID, wireless sensor network (zigbee), Bluetooth, infrared, etc. to achieve positioning. Th...
