Problems solved by technology

[0006] However, in the current positioning method based on the increase in the amount of channel characteristic information, the result of the increase in the amount of channel characteristic information is directly used to perform the matching of the channel characteristic information, and the disadvantages brought about by the increase in the amount of channel characteristic information are ignored. Channel characteristic information error, so that the improvement of positioning accuracy is limited

Abstract

The invention provides an indoor positioning method, related equipment and a computer readable storage medium, which are used for improving the positioning precision of terminal equipment on the basis of increasing the quantity of channel feature information. The method comprises the following steps: when a first spatial position of terminal equipment is determined to be known, updating a channel feature library based on acquired multiple pieces of first channel feature information; training is carried out based on the updated channel feature library, and the number of channel feature information included in the updated channel feature library is increased; acquiring first channel feature compensation information corresponding to the channel feature library after the quantity of the channel feature information is increased based on the channel feature library after the quantity of the channel feature information is increased; and the positioning server or the terminal device positions the terminal device based on the channel feature library after the number of the channel feature information is increased and the first channel feature compensation information.

Description

technical field [0001] The present application relates to the field of wireless communication technologies, and in particular, to an indoor positioning method and related devices, and a computer-readable storage medium. Background technique [0002] Positioning technology based on wireless communication can be used for positioning indoors or outdoors, so as to facilitate user navigation, find people or objects, and so on. For indoor positioning, since satellite signals are weak when they reach the ground and cannot penetrate buildings, the global positioning system (GPS) cannot be used for positioning in indoor environments, and wireless communication is usually used for positioning, such as based on Positioning is performed using Bluetooth beacons, wireless fidelity (Wi-Fi), and macro base station-based positioning technologies. [0003] A typical method based on the Wi-Fi positioning technology is to use a positioning technology based on a received signal strength indicat...
