Pedestrian indoor walking positioning method, device and storage medium

Abstract

The invention provides a pedestrian indoor walking positioning method, device and storage medium. The method comprises: obtaining original data of the walking target pedestrian through a monitoring device arranged at the foot of the target pedestrian, wherein the original data comprises state parameters and geomagnetic characteristic quantities; solving the state parameters to obtain walking parameters and eliminate the error of the walking parameters; performing position estimation according to the walking parameters of which the error is eliminated to obtain the position estimation data of the current position of the target pedestrian; matching the geomagnetic characteristic quantities with the geomagnetic characteristic quantities in the geomagnetic fingerprint database to obtain current geographic position data of the target pedestrian; and calculating the position estimation data and the current geographic position data according to a particle filtering algorithm to obtain the current position of the target pedestrian. According to the pedestrian indoor walking positioning method, device and storage medium, the positioning accuracy is improved.

Description

technical field [0001] The present invention mainly relates to the technical field of positioning, in particular to a pedestrian positioning method, device and storage medium for indoor walking. Background technique [0002] With the development of human beings and the progress of society, people's social activities are increasing, and people's travel is increasingly inseparable from the demand for location information. In today's society, most of people's activities are carried out indoors. When indoors, the signal of the satellite positioning system is affected, resulting in the unsatisfactory effect of obtaining their own location information through the satellite positioning system when indoors. At present, there are also Wi-Fi / Bluetooth The equipment and GPS / Beidou system can realize the indoor positioning of pedestrians, but it cannot be used indoors without Wi-Fi. At the same time, there is a large investment in Wi-Fi / Bluetooth equipment. The equipment needs regular m...
