Embodiment 1

[0082] figure 1 A flow schematic of a flow of seamless switching methods based on mobile terminal indoors, such as this embodiment, such as figure 1 Distance

[0083] A seamless switching method based on a mobile terminal indoors, which includes the following steps:

[0084] Positioning switching buffer processing: Extract the building entrance and exit area, after processing the positioning switching buffer, laying the sensor device in the positioning switching buffer, with the mobile terminal itself with the operating system sensor interface, scan position sensor data, after scanning The data is processed to obtain position sensor fingerprint data and save it to the local fingerprint database;

[0085] Parameter setting: Conversion of the coordinate system conversion to the map data under different coordinate systems indoor and outdoor, forming a map data of the unified coordinate system; the buffer time threshold, indoor positioning error threshold, and outdoor positioning err...

Abstract

The invention discloses a method for seamless switching based on mobile terminal indoor and outdoor positioning, and relates to the technical field of positioning for mobile terminals. It is characterized in that the method includes the following steps: processing a positioning switching buffer; Set the buffer time threshold, indoor positioning error threshold and outdoor positioning error threshold; determine the current area of ​​the mobile terminal, if the mobile terminal is in the positioning buffer area, start the positioning switching algorithm, and determine the indoor and outdoor areas where the mobile terminal is located , start the indoor-to-outdoor positioning switching mode or the outdoor-to-indoor positioning switching mode respectively, and perform seamless switching between indoor and outdoor positioning of the mobile terminal. Advantages: The indoor positioning coordinate reference is unified into the outdoor GPS / Beidou positioning coordinate system, which solves the coordinate conversion problem in the seamless switching between indoor and outdoor positioning. Realize seamless switching between indoor and outdoor positioning.

Description

Technical field [0001] The present invention relates to the field of positioning techniques for mobile terminals, specifically a method of changing indoors between indoor positioning and global satellite navigation systems and sensors in a wireless transmission technology, and seamless switching in indoors and intercom. The method can adaptively control the seamless switching method of seamless switching of the mobile terminal indoors through the hardware and hardware by detecting the environmental changes. Background technique [0002] With the development of human society, people's demand for their own location information is getting bigger and bigger, thereby developing many navigation positioning systems. Global Satellite Navigation System (GNSS) provides high-precision, all-weather positioning services, but due to its characteristics of the measurement signals that cannot penetrate the buildings, GNSS positioning services cannot be effectively carried out in high-intensive c...
