Abstract

The invention provides an indoor positioning method. The method comprises the following steps: pre-constructing a geomagnetic fingerprint database corresponding to a to-be-positioned indoor space; real-time geomagnetic information of the position where the mobile carrier is located and acceleration information and azimuth angle information of the mobile carrier are measured in real time; and determining the current position information of the mobile carrier according to the geomagnetic fingerprint database, the real-time geomagnetic information, the acceleration information and the azimuth angle information by using a particle filtering algorithm.

Description

technical field [0001] The present application relates to the field of intelligent positioning, and in particular, to an indoor positioning method, device, computer equipment and storage medium. Background technique [0002] With the rapid development of the Internet of Things technology, in order to strengthen the safety management and control of indoor personnel, the positioning requirements of the power system are gradually changing from outdoor to indoor. The global satellite navigation system cannot receive enough satellite signals in the indoor environment and cannot provide accurate Location Services. [0003] At present, there are a variety of positioning solutions in the field of indoor positioning, including technical solutions based on Wi-Fi, RFID, Bluetooth, UWB, and visible light. However, under the influence of complex indoor environment, construction cost and other factors, the existing indoor solutions all have certain defects. For example, the indoor positi...
