Description

A positioning system and positioning method based on two-dimensional code, gyroscope and accelerometer and information service methods

technical field

The invention relates to a positioning system and method, in particular to a positioning system, a positioning method and an information service method based on a two-dimensional code, a gyroscope and an accelerometer.

Background technique

With the popularization of the Internet and mobile phones in the information age, people's daily life and work are increasingly relying on GPS positioning-based travel navigation, but GPS positioning and navigation is limited to outdoor use, and the indoor positioning accuracy is limited due to the covering of buildings. Very low, basically unusable. For example, it is difficult for passengers in subways, railway stations, and airport terminal buildings to find the location of their train and flight smoothly. It is also difficult for exhibitions, theaters, and stadiums to find the booths they want to visit and their seats. In shopping malls and supermarkets I don't know which floor or where the product I want to buy is located. When I go to the hospital for a doctor, I have to inquire many times before I can find the consulting room for the doctor. Games based on LBS location services, such as the very popular Pokemon Go, can only be played outdoors by relying on GPS positioning, and cannot be played indoors. These indoor places urgently need a simple, reliable and practical positioning system to meet the needs of users.

In the prior art, there is a method that uses two-dimensional codes as position coordinates, uses mobile phone cameras to capture two-dimensional codes to obtain position information and sends them to the system server for query to determine the actual position, but this method requires a lot of settings on the user's walking path The two-dimensional code position mark is for users to obtain. The more the number of two-dimensional code coordinates on the system path, the more precise and accurate the positioning will be, otherwise it will be very rough. Therefore, in order to obtain a better positioning effect, it is necessary to set it indoors A large number of two-dimensional code signs increases the difficulty of construction, and the user keeps taking photos of the two-dimensional code signs during walking, which is not only troublesome, but also seriously affects the walking speed of the user. In addition, whether it is advertising services, online or offline shopping e-commerce or physical stores, and social platforms are limited to fixed venues and systems, there is a lack of precise services based on user locations and interaction between users and merchants and systems.
