Problems solved by technology

[0004] When the user enters the room from the outside, the satellite signal is likely to be lost or the signal is too weak due to the occlusion of the building, resulting in poor or even impossible positioning of the GNSS outdoor positioning. Incomplete indoor map information needs to be searched and downloaded through the wireless communication network, and indoor positioning cannot be performed during the period. This situation that indoor and outdoor positioning cannot be realized will lead to poor user experience

Embodiment Construction

[0018] The solution of the present invention will be described in detail below in combination with the preferred embodiments thereof.

[0019] Such as figure 1 As shown, the method in this embodiment includes steps:

[0020] S101: Set up a wireless hotspot AP at an outdoor preset location, obtain outdoor coordinate information of the preset location through GNSS positioning signals; and detect whether the mobile terminal enters the radiation range of the wireless hotspot AP, and enter S102.

[0021] At present, in public places, such as railway stations, airports, parking lots, shopping malls, coffee shops, museums, libraries and other places, the demand for indoor navigation applications is also increasing day by day. Wi-Fi and Bluetooth modules are gradually becoming the standard configuration of smart phones, making Wi-Fi and Bluetooth positioning a common technology for indoor positioning in the public domain. Generally, only corresponding WLAN signal sending devices are...

Abstract

The invention provides an indoor and outdoor hybrid positioning method, which comprises the steps of: setting wireless hotspots at an outdoor preset position, and acquiring outdoor absolute coordinate information of the preset position through a GNSS static measurement tool; detecting whether a mobile terminal enters a radiating range of the wireless hotspots; if so, judging whether the number of current GNSS available satellites acquired by the mobile terminal is less than a preset value; and if so, setting a final outdoor coordinate value of the mobile terminal as an initial value, utilizing the GNSS available satellites and the wireless hotspots for hybrid positioning, and being capable of obtaining an effective positioning result under the condition that the sum of numbers of the wireless hotspots and the available satellites is greater than or equal to 4. The indoor and outdoor hybrid positioning method can solve the problem that GNSS positioning is unstable since satellite signals are blocked by crowded tall buildings in city and the satellite signals received by subordinate users under many tall buildings are weak, and improves user experience. The invention further provides an indoor and outdoor hybrid positioning system.

Description

technical field [0001] The invention relates to the technical field of indoor and outdoor positioning, in particular to a method and system for indoor and outdoor hybrid positioning. Background technique [0002] With the gradual maturity of indoor positioning technology, some large public indoor places (such as airports, shopping malls, exhibition halls, etc.) have provided indoor positioning and navigation systems. Since indoor positioning in the public domain often uses common smart phones as mobile terminals, and Wi-Fi modules and Bluetooth modules have become the standard configuration of smart phones, indoor positioning technology generally uses Wi-Fi positioning or Bluetooth positioning, and indoor positioning systems generally use A system mode that combines wireless hotspot AP (Wi-Fi or Bluetooth base station), smart terminal, and APP software. Users can locate their location in real time after downloading the APP through the smart terminal, and can also quickly qu...
