Problems solved by technology

[0002] At present, the demand for indoor positioning and navigation is increasing, and the requirements for it are also getting higher and higher. Currently, the most widely used is to use the global positioning system (global positioning system, GPS) for navigation. However, due to the complex indoor environment, GPS Satellite signals are blocked and interfered, which can easily lead to inaccurate positioning and navigation

Abstract

The invention provides a positioning and navigation method, a positioning and navigation device and a storage medium, wherein the method comprises the following steps: performing primary positioning for a target carrier in a monitoring range, calculating motion information of the target carrier under a geographic coordinate system, and converting the motion information into the motion informationunder a world coordinate system, obtaining the current position coordinate and speed of the target carrier according to the converted motion information, obtaining motion trail according to the current position coordinate and the speed, acquiring beacon position information of a beacon preset in the monitoring range, obtaining relative position data between the target carrier and the beacon according to the beacon position information and the current position coordinate of the target carrier, and regulating the motion trail of the target carrier according to the relative position data. According to the method and the device provided by the invention, the current position coordinate, the speed and the motion trail of the target carrier in the geographic coordinate system are obtained through calculation of the motion information of the target carrier, the motion trail of the target carrier is regulated according to the relative position of the target carrier and the beacon, and thus, positioning and navigation of the target carrier can be more accurate.

Description

technical field [0001] The present invention mainly relates to the technical field of positioning and navigation, in particular to a positioning and navigation method, device and storage medium. Background technique [0002] At present, the demand for indoor positioning and navigation is increasing, and the requirements for it are also getting higher and higher. Currently, the most widely used is to use the global positioning system (global positioning system, GPS) for navigation.
