Subway station fingerprint database update method, device, computer equipment and storage medium

Abstract

The present application provides a method, device, computer equipment and storage medium for updating a fingerprint database of a subway station, which can determine the positioning log of an electronic device using a location service, and obtain from the positioning log all target log information indicated by the positioning point at the target subway station. at least one AP; determine at least one target AP that satisfies the fingerprint condition in the at least one AP; determine the positioning point to which each target AP belongs in the at least one target AP respectively, and generate the fingerprint of the target subway station according to the positioning point to which the target AP belongs; and then combine The generated fingerprints and the valid fingerprints determined based on the positioning log and the initial fingerprint database of the target subway station construct the fingerprint database of the target subway station. The present application can automatically update the initial fingerprint database of the target subway station by directly relying on the location log of the electronic device using the location service, thereby reducing the labor cost of updating the fingerprint database of the target subway station.

Description

technical field [0001] The present invention relates to the field of information technology, and more particularly, to a method, device, computer equipment and storage medium for updating a fingerprint database of a subway station. Background technique [0002] Indoor positioning technology can determine the indoor location of mobile devices through wireless sensor signals or mechanical sensor signals, combined with reference points and database information. The reference point may be an AP (Wireless Access Point, Wireless Access Point), and the determination of the indoor AP plays a pivotal role in the indoor positioning technology. [0003] Especially in the indoor environment of a subway station, the positioning of electronic devices provides great convenience for users with electronic devices to travel. If the subway station AP is inaccurately determined, it often leads to inaccurate positioning of electronic devices in the subway station. , affecting user travel. [0...

Problems solved by technology

[0003] Especially in the indoor environment of the subway station, the positioning of electronic devices provides great convenience for the travel of users holding electronic devices. If the AP of the subway station is not determined accurately, it often leads to inaccurate positioning of electronic devices in the subway station. , affecting user travel

[0004] At present, each AP in the subway station collected manually is usually regarded as a fingerprint of the subway station to construct the initial subway station fingerprint library, but as time goes by, the subway station fingerprint library may involve updating

In the existing technology, when updating the fingerprint database of subway stations, it either relies on the manually collected crowdsourcing data of the subway station, or relies on the AP collected manually at the measurement site of the subway station. The update of the fingerprint database is expensive and cannot be realized. Automatic update of subway station fingerprint database
