Positioning system and positioning method based on two-dimensional codes, gyroscope and accelerometer as well as information service method

Abstract

The invention provides a positioning system and a positioning method based on two-dimensional codes, a gyroscope and an accelerometer as well as an information service method. The system comprises two-dimensional codes, and further comprises a mobile phone with the gyroscope, the accelerometer and a camera therein and a system server, wherein a two-dimensional code mark which represents the position of a user is arranged on a main position of a user travelling path; the mobile phone camera of the user establishes image information catching connection with the two-dimensional code mark to shootthe two-dimensional codes to obtain main information position; the mobile phone gyroscope and the accelerator establish motion information catching connection with action of the user to capture a user motion direction and acceleration information; the user mobile phone establishes communication connection with the system server to send the obtained two-dimensional code position information as well as the user motion direction and the acceleration information caught by the gyroscope and the accelerometer to the system server; and a practical position and position map information sent to the mobile phone by the system server is received for the user to check.

Description

technical field [0001] 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 [0002] 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 wa...

Problems solved by technology

[0004] The technical problem to be solved in the present invention is to provide a positioning system and positioning method and an information service method based on two-dimensional codes, gyroscopes and accelerometers, to solve the problem of difficult positioning indoors, and to realize positioning based on two-dimensional codes, gyroscopes and accelerometers. Indoor positioning and information services of the positioning system, the system includes two-dimensional codes, mobile phones with built-in gyroscopes, accelerometers and cameras, and system servers, and two-dimensional code signs representing their own positions are set at the main positions of the user's walking path. The camera of the user's mobile phone establishes an image information capture connection with the QR code sign, captures the QR code to obtain location information, and the gyroscope and accelerometer of the mobile phone establishes a motion information capture connection with the user's actions to capture the user's movement direction and acceleration information. The system server establishes a communication connection, and sends the obtained QR code location information and the user's motion direction and acceleration information captured by the gyroscope and accelerometer to the system server, and receives the actual location and location map information sent by the system server to the mobile phone for the user to view. And receive the service information of the location and reply or operate the service information to realize information interaction
