Abstract

The invention relates to an indoor and outdoor seamless positioning system integrated with satellite navigation and a bluetooth technology, and a method thereof. The system comprises an outdoor satellite positioning module, an indoor bluetooth positioning module, an indoor and outdoor positioning fusion switchover module, and an electronic map display module. The outdoor satellite positioning module performs outdoor positioning by using GPS or Beidou Satellite navigation terminals. The indoor bluetooth positioning module performs indoor positioning by using a field intensity attenuation principle and a three-dimensional spatial positioning algorithm. The indoor and outdoor positioning fusion switchover module performs fusion, switchover, and integration on indoor and outdoor positioning methods according to strength of indoor and outdoor positioning communication signals and based on a federated kalman filter, so as to realize smooth transition of indoor and outdoor positioning. The electronic map display module displays positioning results based on two-dimensional electronic maps or indoor plane graphs, and three-dimensional building model scene graphs. The system can provide an indoor and outdoor integrated positioning function for intelligent mobile devices, and positioning speed is fast, and positioning precision is high.

Description

technical field [0001] The invention relates to the technical field of navigation and positioning or location services, in particular to an indoor and outdoor seamless positioning system integrating satellite navigation and bluetooth technology and a method thereof. Background technique [0002] With the increasing maturity of global satellite navigation and positioning systems such as GPS, Beidou, and GLONASS, people enjoy fast and accurate positioning services, and a large number of professional applications have also grown rapidly, such as traffic navigation, field measurement, and missile guidance. However, due to the limitations of satellite positioning technology, positioning technologies such as GPS and Beidou cannot be effectively applied to indoor scenes. Inside a large building, affected by the occlusion of the concrete wall, etc., the GPS signal will be weakened sharply so that positioning cannot be achieved. With the development of applications such as indoor bu...
