Abstract

The invention relates to a personnel indoor positioning method and a personnel indoor and outdoor integrated positioning method, belongs to the technical field of positioning, and provides indoor andwhole-airspace covered position information services for personnel. According to the personnel indoor positioning method, wireless signal data, air pressure height data, magnetic field acquisition data and pedestrian acceleration and angular rate data which are collected by the personnel in an indoor walking process are obtained, wireless base station data and geomagnetic map data are distributedin combination with a positioning area stored in the database, and the positioning and resolving of the personnel are carried out on the basis of a fusion positioning method of particle filtering. Themethods can provide indoor and whole-airspace covered position information services for the personnel, and are used for emergency rescue, safety management, positioning navigation and other scenes.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to an indoor positioning method for personnel and an integrated indoor and outdoor positioning method. Background technique [0002] Positioning technology refers to the formation of a position positioning system through the integration of various technologies such as wireless communication, base station positioning, and inertial navigation positioning, so as to provide applications for military command, aerospace, transportation, meteorology, travel, emergency rescue, and safety monitoring Provides location services. [0003] With the development of mobile communication and wireless sensor network, positioning technology has gradually entered a new stage. Satellite positioning and navigation technologies based on GPS and Beidou have been widely and maturely applied outdoors, but in indoor, underground, caves, urban streets, mountain jungles and other applications where satelli...
