Abstract

The invention belongs to the field of indoor positioning, in particular to an indoor positioning and motion tracking method combined with magnetic field and inertia and an implementation system, wherein the system includes a data collection front end and a data processing server back end; the data collection front end includes collecting magnetic field distribution characteristic information and acceleration angular velocity Information data acquisition module, storage control module for storing and preprocessing data, and data sending module for data sending; data processing service terminal includes receiving module, data processing module, local server database and location Real-time display module for information and sports information. The system positioning principle of the present invention is simple, and the present invention uses the characteristic parameters of the space magnetic field environment where the positioned target is located to perform database recording and matching and real-time motion inertia parameter calculation, and realizes indoor areas where satellite signals cannot be completely covered or coverage signals are poor position.

Description

technical field [0001] The invention belongs to the field of indoor positioning, and in particular relates to an indoor positioning and motion tracking method combined with magnetic field and inertia and a realization system. Background technique [0002] At present, neither the GPS nor the Beidou positioning system can directly locate the targets in the modern living environment, especially the indoor environment, in most cases. The main reason is that the signal wavelength of the satellite positioning cannot penetrate building obstacles, and the The GPS positioning accuracy of the company is within 10 meters, which cannot meet the requirements of high accuracy for small indoor positioning environments. The built-in GPS positioning of common mobile phones cannot be located after the mobile phone card is unplugged. The network positioning of mobile phones is also based on base station or network IP positioning. At the same time, using indoor invisible light positioning and ...
