Embodiment 1

[0082] figure 1 A schematic flowchart of a method for seamless handover based on mobile terminal indoor and outdoor positioning provided in this embodiment, as shown in figure 1 as shown,

[0083] A method for seamless switching based on indoor and outdoor positioning of a mobile terminal, the method comprising the following steps:

[0084] Positioning switching buffer processing: Extract and process the entrance and exit area of ​​the building to generate a positioning switching buffer, lay sensor equipment in the positioning switching buffer, scan the position sensor data through the mobile terminal itself equipped with the operating system sensor interface, and scan the position sensor data. Process the data to obtain the position sensor fingerprint data and save it to the local fingerprint database;

[0085] Parameter setting: coordinate system conversion for map data in different indoor and outdoor coordinate systems to form map data in a unified coordinate system; buff...

Abstract

The invention discloses an indoor and outdoor positioning seamless switching method based on a mobile terminal, which relates to the technical field of mobile terminal positioning. The method includesthe following steps: processing a positioning switching buffer region; setting a buffer time threshold, an indoor positioning error threshold and an outdoor positioning error threshold required in amobile terminal positioning switching algorithm; and determining the region where a mobile terminal is located currently, and if the mobile terminal is in the positioning switching buffer region, starting the positioning switching algorithm, and starting an indoor-to-outdoor positioning switching or outdoor-to-indoor positioning switching mode by determining whether the mobile terminal is locatedindoors or outdoors, in order to carry out seamless switching between indoor positioning and outdoor positioning of the mobile terminal. The advantage is that an indoor positioning coordinate datum isconverted into an outdoor GPS / BeiDou positioning coordinate system, and the problem of coordinate conversion in indoor and outdoor positioning seamless switching is solved. Seamless switching betweenindoor positioning and outdoor positioning is realized.

Description

technical field [0001] The invention relates to the technical field of positioning of mobile terminals, specifically a method for indoor and outdoor positioning between wireless transmission technology indoor positioning and global satellite navigation systems and sensors, and seamless switching between indoors and outdoors. The method is a seamless switching method based on the indoor and outdoor positioning of the mobile terminal, which can detect the change of the environment and adaptively monitor the indoor and outdoor of the mobile terminal through software and hardware. Background technique [0002] With the development of human society, people's demand for their own location information is increasing, thus many navigation and positioning systems have been developed. The global satellite navigation system (GNSS) provides people with high-precision, all-weather positioning services, but due to the characteristics that its measurement signals cannot penetrate buildings,...
