Abstract

The invention provides an indoor positioning method, a device, electronic equipment and a storage medium. The method comprises the following steps: collecting WiFi signal data and indoor image data of a current position; inputting the WiFi signal data and the indoor image data into an indoor positioning model to obtain a predicted position of the current position output by the indoor positioning model; wherein the indoor positioning model is used for respectively extracting signal features in the WiFi signal data and image features in the indoor image data, and performing positioning prediction after fusing the signal features and the image features. According to the method, the device, the electronic equipment and the storage medium provided by the invention, the WiFi signal data and the indoor image data are directly used for fusion positioning, and the precision and the efficiency of indoor positioning are improved.

Description

technical field [0001] The present invention relates to the technical field of computers, in particular to an indoor positioning method, device, electronic equipment and storage medium. Background technique [0002] In an indoor environment, due to factors such as attenuation and occlusion of the Global Navigation Satellite System (GNSS) signal, the location information of the user cannot be obtained, or the obtained location information of the user is not accurate enough. Therefore, other signals can be used for indoor positioning, such as WiFi, Bluetooth, magnetic fields, visible light, acoustic signals, and images. At present, the research on indoor positioning technology can be divided into two categories according to the type of sensor used: positioning technology based on wireless devices and positioning technology based on visual images. [0003] The deployment method of positioning technologies based on wireless devices, such as WiFi and Bluetooth, directly affects ...
