Abstract

The invention provides an indoor positioning method. The indoor positioning method comprises the following steps: firstly collecting initial positioning information of a target object, wherein the initial positioning information includes an arbitrary number of surrounding WiFi hotspot information, surrounding Bluetooth equipment information, geomagnetic information, atmospheric pressure information and TC-OFDM multimode sensing signals; then selecting a corresponding initial positioning method according to the collected initial positioning information and a preset screening strategy; carrying out initial positioning by virtue of the initial positioning method, so as to obtain an initial positioning result of the target object; besides, collecting inertial navigation data generated during the indoor walking of the target object; and finally positioning and tracking the target object by virtue of a preset positioning-tracking method according to the initial positioning result and the inertial navigation data, so as to obtain real-time positioning information of the target object. By virtue of the indoor positioning method, the indoor positioning is realized by combining the initial positioning method with the positioning-tracking method, the compatibility is strong, the application range is wide, a large number of network nodes do not need to be distributed, the positioning is accurate, and the cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of navigation and positioning, in particular to an indoor positioning method and device. Background technique [0002] With the development of mobile Internet technology, location-based services (Location Based Servers, LBS) have received extensive attention. According to statistics, more than 80% of the information used by people is related to "location", and people's demand for seamless indoor and outdoor positioning is also increasing. [0003] At present, the outdoor positioning technology is quite mature, and the world's four major satellite navigation systems represented by GPS, Beidou, Galileo and GLONASS have been widely promoted and applied. However, for indoor environments where satellite positioning signals are difficult to cover, although there are indoor positioning technologies based on technologies such as Wi-Fi, ZigBee, RFID, Bluetooth, and ultra-wideband, the realization of the above-mentio...
