Calibration method, system, server and medium for wireless signal fingerprint information

Abstract

Disclosed in the present invention is a wireless signal fingerprint information calibration method, comprising the following steps: receiving wireless signal information uploaded by a collection terminal, wherein the wireless signal information comprises first wireless signal information and second wireless signal information; generating corresponding fingerprint information to be verified on the basis of the first wireless signal information and the region name of a collection region, and storing the fingerprint information to be verified in a wireless signal fingerprint database; carrying out traversal matching on the second wireless signal information and the wireless signal fingerprint database so as to determine whether the fingerprint information to be verified is effective or not; and if the fingerprint information to be verified is not effective, removing the fingerprint information to be verified from the wireless signal fingerprint database so as to collect the wireless signal information again. Also disclosed in the present invention are a wireless signal fingerprint information calibration system, a server and a medium. The present invention improves efficiency and accuracy of wireless signal information collection and reduces the collection costs.

Description

technical field [0001] The invention relates to the technical field of indoor positioning, in particular to a calibration method, system, server and medium of wireless signal fingerprint information. Background technique [0002] The market demand for indoor positioning is growing day by day, especially in the indoor navigation of large shopping malls and office buildings. Indoor location information is the data basis for indoor positioning, and wireless signal space, especially WIFI signals, has been widely used in the industry in indoor positioning scenarios. [0003] However, the collection of front-line links often consumes a lot of manpower and material resources and the quality is not high. The reasons mainly include two aspects: 1. The hardware where the mac address of the WIFI signal is located may be a mobile hotspot or an illegal router, rather than from a stable geographical location. And the relative geographical location has different hardware, that is, the WIF...

[0003] However, the collection of front-line links often consumes a lot of manpower and material resources and the quality is not high. The reasons mainly include two aspects: 1. The hardware where the mac address of the WIFI signal is located may be a mobile hotspot or an illegal router, rather than from a stable geographical location. And the relative geographical location has different hardware, that is, the WIFI signal is an invalid signal; 2. The location of the collection point is inappropriate, such as in the public area of ​​different stores, rather than the entrance or store of a certain store, that is, the collection of this point is invalid At the collection point, when the wireless signal information collected by the collection terminal is inaccurate, the server cannot adjust it in time, and if there is a problem during the user's use, it needs to be collected again, wasting a lot of human and material resources
