Document Type and Number:
WIPO Patent Application WO/2024/041112
Kind Code:
A1
Abstract:
Disclosed are a positioning method and apparatus, a device, and a storage medium. The method comprises: gridding a vehicle running route to obtain a plurality of grids; storing grid information and radio frequency fingerprint sample data of each grid into a database; and positioning a terminal device according to radio frequency fingerprint data and the radio frequency fingerprint sample data. In this way, the vehicle running route is gridded according to running route features, the radio frequency fingerprint sample data of each grid is stored, the radio frequency fingerprint data actually acquired by the terminal device is combined for positioning, and grid information of a grid where the terminal device is located is determined, thereby achieving the positioning function of the terminal device in special mobile scenes such as subways, high-speed railways, and highways. In addition, a data acquisition strategy can also be designed according to the running route features, an acquisition frequency is decreased in a place having a low positioning requirement, and the acquisition frequency is increased in a place having a high positioning requirement, thereby reducing power consumption caused by positioning while positioning requirements and positioning precision are ensured.
