Abstract

The invention discloses an indoor positioning method and device based on WiFi longitude and latitude. The method includes: when receiving a WiFi scanning request from a mobile terminal, recording the signal parameters of the WiFi signal detected in the current indoor space and forming the longitude and latitude information of the mobile terminal. Database; calibrate the longitude and latitude of each WiFi signal according to the signal parameters in the database and the longitude and latitude information of the mobile terminal; when performing indoor positioning, scan the calibrated WiFi signal to obtain its longitude and latitude coordinates, according to the longitude and latitude coordinates of the calibrated WiFi signal and The current latitude and longitude of the mobile terminal is calculated from the signal strength received by the mobile terminal. The embodiment of the present invention realizes indoor positioning by recording WiFi information and longitude and latitude information when the mobile terminal scans WiFi to form a database, without artificially collecting WiFi fingerprint database data in advance, saving a lot of manpower and material resources, and lower positioning costs than traditional WiFi fingerprint databases And the database acquisition method is more flexible.

Description

technical field [0001] The present invention relates to the technical field of indoor positioning, in particular to an indoor positioning method and device based on WiFi longitude and latitude. Background technique [0002] Nowadays, people's demand for location information in indoor scenes is gradually increasing. The acquisition of location information is conducive to people's perception and familiarity with unknown environments, which has also led to indoor positioning becoming a major research hotspot at this stage. It is difficult to obtain positioning information through GPS positioning, so indoor positioning technology uses common signal types in indoor environments, including WiFi, ZigBee, Bluetooth, geomagnetic field, ultra-wideband, radio frequency, etc. [0003] Among them, the WiFi signal is currently the most widely used signal type, but the existing WiFi positioning methods are all conventional WiFi fingerprint database positioning, which requires manual collec...
