Problems solved by technology

[0003] However, in the prior art, in model prediction, the positioning effect of a single model is often worse than the result obtained by combining multiple model predictions, but training more models will slow down the training, and the number of model parameters will also increase with the number of models. rapidly increase

Abstract

The embodiment of the invention relates to the field of communication, and discloses an indoor positioning method and device, electronic equipment and a storage medium. The indoor positioning method comprises the steps of acquiring received signal strength RSS information of a positioning area, wherein the received signal strength RSS information is composed of labeled RSS data and unlabeled RSS data; performing data processing on the labeled RSS data and the unlabeled RSS data to obtain mixed data; training the mixed data through a pre-built student model and updating parameters of the student model; updating parameters of a pre-established teacher model by adopting a parameter weighted average algorithm according to the parameters of the student model; and acquiring RSS information to betested, and obtaining predicted two-dimensional coordinates through the updated teacher model. The method is applied to an indoor environment to obtain the position of a user.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, to an indoor positioning method, device, electronic equipment, and storage medium. Background technique [0002] With the rapid expansion of the mobile Internet and the popularity of smart terminal devices, the indoor positioning technology based on mobile devices has also been developed. The current mainstream indoor positioning method based on WiFi fingerprint mainly includes two stages: offline database construction stage and online positioning stage. In the offline database construction stage, some reference points need to be determined in advance indoors, and the Received Signal Strength (RSS) information of multiple access points of the reference points is collected to build a fingerprint database; in the online positioning stage, a user to be tested is obtained After obtaining the RSS information, according to the existing fingerprint database, compare an...
