Abstract

The invention discloses a positioning method which comprises the following steps: in a Radio Map database, obtaining first signal strength information received by a reference position within a presettime, wherein the first signal strength information is the signal strength of a signal which is received by the reference position at different time points and is transmitted for an access point; based on the first signal intensity information of the reference position, generating a first weight value corresponding to each piece of first signal intensity information and a second weight value corresponding to each access point; determining the position of the user terminal based on the Radio Map database, second signal strength information received by the user terminal, the first weight value and the second weight value. The invention further discloses a terminal and a computer readable storage medium.

Description

technical field [0001] The present invention relates to the field of positioning technology, in particular to a positioning method, a terminal and a computer-readable storage medium. Background technique [0002] In people's daily life, location services are widely used, such as route navigation, searching for the location of electronic devices, and so on. Among them, the wireless local area network (Wirelss Local Area Networks, WLAN) positioning technology has been widely used due to its advantages of easy deployment and no need for additional hardware devices. [0003] The WLAN positioning technology includes an offline radio map (Radio Map) establishment phase and an online positioning estimation phase. In the stage of establishing the offline Radio Map, the signal strength information of each access point (Access Point, AP) received by the terminal is used as fingerprint data to construct the Radio Map. In the online location estimation phase, the user's location is es...
