Abstract

The invention provides a calibration method. The calibration method includes the following steps that: a calibration device moves indoor; the calibration device is composed of an inertial navigation device, a wireless signal transmitting and receiving device and a bogie; the inertial navigation device is used for measuring the current position information of the calibration device; the wireless signal transmitting and receiving device is used for wirelessly exchanging positioning signals with an in indoor positioning system; and the bogie moves indoors according to a preset line and traverses an indoor space. The calibration method of the invention has universality. With the calibration method adopted, a variety of different kinds of indoor positioning systems can be rapidly calibrated, so that the calibration cost of the indoor positioning systems can be significantly reduced.

Description

technical field [0001] The invention belongs to the field of positioning, in particular to a calibration method. Background technique [0002] Services based on location information have been widely used, among which the most well-known to the public is the use of GPS (Global Positioning System, Global Positioning System) for vehicle navigation. Among the existing services based on location information, most of them can only be applied outdoors. [0003] If it is desired to implement long-term (such as several years) positioning tracking services indoors, it is generally necessary to install a series of base stations indoors. The base station can be considered as an "indoor satellite", and through the cooperation of multiple base stations, an "indoor GPS system" can be realized. After the base station is initially installed, it needs to be calibrated before it can be put into use. The purpose of the calibration is to eliminate system errors and ensure positioning accuracy....
