Indoor and outdoor seamless positioning system based on Android device and positioning method thereof

Abstract

The invention discloses an indoor and outdoor seamless positioning system based on an Android device. The indoor and outdoor seamless positioning system comprises an outdoor positioning part, an indoor positioning part, a background detection part and a function configuration part; the outdoor positioning part comprises an outdoor electronic map and a GPS module; the GPS module is used for obtaining a latitude and longitude coordinate of the current position, correcting and converting the latitude and longitude coordinate into encrypted latitude and longitude data and displaying the same on the outdoor electronic map; the background detection part comprises a floor detection module and an environment detection module; the floor detection module obtains an altitude of the current position in real time; the environment detection module is used for detecting the environment of the current position in real time; the indoor positioning part is used for indoor space positioning and displaying a positioning result on an indoor electronic map; and the function configuration part is used for establishing and checking a WIFI fingerprint base. The indoor and outdoor seamless positioning system disclosed by the invention integrates GPS positioning and WIFI fingerprint positioning and combines indoor and outdoor environment detection and floor detection to realize true seamless positioning. The indoor and outdoor seamless positioning system disclosed by the invention is good in universality, low in cost and high in positioning precision.

Description

technical field [0001] The invention relates to the field of positioning technology and location service technology, in particular to an Android-based indoor and outdoor seamless positioning system and method integrating GPS, WIFI positioning technology and multi-sensor fusion. Background technique [0002] With the rapid development of information technology, the demand for location-based services is increasing, and people's desire to obtain location information anytime and anywhere is becoming more and more intense. [0003] At present, global satellite navigation and positioning systems such as GPS, GLONASS and Beidou positioning and navigation are becoming more and more mature, and have been successfully used in military, industrial, commercial and other fields. However, due to the limitations of satellite positioning technology itself, the above-mentioned global satellite navigation and positioning system cannot be directly transplanted into indoor scenes, and is blocke...

AI Technical Summary

Problems solved by technology

However, due to the limitations of satellite positioning technology itself, the above-mentioned global satellite navigation and positioning system cannot be directly transplanted into indoor scenes, and is blocked by walls, buildings, etc., and GPS and other signals are so attenuated that it is impossible to locate indoors, so people began to explore indoor scenes. Under the current positioning technology, Bluetooth, WIFI, ultrasonic, infrared, RFID, Zigbee and other positioning technologies have emerged and are experiencing a period of vigorous development.
