Abstract

The invention discloses an indoor and outdoor multi-technology fused positioning method, and aims at effectively overcoming defects among various existing positioning technologies when an intelligentterminal is not used. The method comprises the following steps: 1, synchronously acquiring indoor and outdoor positioning information which comprises an indoor wireless signal RSSI value and outdoor satellite positioning data; 2, resolving the RSSI value of the indoor wireless signal to obtain coordinates of an indoor positioning plane map; 3, resolving the outdoor satellite positioning data to obtain outdoor positioning plane map coordinates; 4, judging and positioning floors; 5, evaluating the coordinate precision of the indoor positioning plane map and the coordinate precision of the outdoor positioning plane map, and outputting corresponding coordinates; and 6, outputting required data according to the coordinate data and a map form required by the service. According to the indoor andoutdoor multi-technology fused positioning method, seamless switching between outdoor positioning and indoor positioning can be realized.

Description

technical field [0001] The invention relates to the technical field of positioning and navigation, in particular to an indoor and outdoor multi-technology fusion positioning method. Background technique [0002] With the continuous expansion of the application range of positioning technology, the demand for positioning in emerging applications is not limited to pure outdoor scenarios, but also puts forward new requirements in indoor positioning and mixed positioning in various environments. [0003] However, the traditional positioning technology is mainly suitable for open and unobstructed outdoor locations, using positioning systems established by geostationary satellites, such as the Global Positioning System (GPS), Beidou system, etc. Although the positioning technology of the transmission does not need to deploy positioning coordinates base station equipment for the area that needs to be positioned. However, in an occluded environment, the positioning signal and positi...
