Abstract

The invention belongs to the technical field of indoor positioning, and particularly relates to an indoor positioning method, an indoor positioning device, a computer readable storage medium and terminal equipment. The method comprises the following steps of acquiring current Wi-Fi fingerprint data acquired by terminal equipment in a specified building; processing the current Wi-Fi fingerprint data by using a preset floor classification model to obtain the current floor of the terminal equipment in the specified building; selecting a Wi-Fi fingerprint database sub-base corresponding to the current floor from the Wi-Fi fingerprint database of the specified building; and calculating a positioning coordinate of the terminal equipment in the specified building according to the current Wi-Fi fingerprint data and the Wi-Fi fingerprint data sub-database. According to the embodiment of the invention, the whole indoor positioning process is decomposed into two processes of floor positioning andcoordinate positioning, and compared with the traditional mode of directly carrying out coordinate positioning in the whole building, the method and the device have the advantages that the calculatedamount is greatly reduced, and the method and the device are more practical in large-scale indoor positioning.

Description

technical field [0001] The invention belongs to the technical field of indoor positioning, and in particular relates to an indoor positioning method, device, computer-readable storage medium and terminal equipment. Background technique [0002] In recent years, various indoor positioning technologies have also been developed and improved due to the wide application of Internet and Internet of Things technologies, as well as the increasing popularity of smartphones and other wireless devices in the market. There are many products such as GNSS (Global Navigation Satellite System) receivers on the market today, these products use GPS (Global Positioning System), GLONASS (Glonass Navigation System), Galileo (Galileo Satellite Navigation System) or Beidou system , for real-time satellite positioning. Because the satellite signal will cause signal attenuation when passing through the building surface, it has lost a lot of energy when it reaches the indoor environment. In addition...
