Problems solved by technology

Conventional outdoor positioning methods are generally not suitable for indoor positioning. For example, the Global Positioning System (GPS) can provide high-precision positioning services outdoors, but once indoors, due to the occlusion of buildings, GPS positioning is basically difficult. fail
However, the current common indoor positioning methods (such as Wi-Fi indoor positioning, radio frequency identification indoor positioning and infrared positioning) generally need to lay auxiliary equipment according to a certain density in advance, which will make the network architecture of indoor positioning more complex.

Abstract

The embodiment of the present invention relates to the field of positioning technology, and discloses a mobile device positioning method and system in an indoor environment, and a mobile device. The method includes: the first mobile device acquires the location information of the second mobile device, and the first mobile device and the The distance between the two mobile devices, and the relative azimuth angle between the first mobile device and the second mobile device, and according to the location information of the second mobile device, the distance between the first mobile device and the second mobile device, and the distance between the first mobile device and the second mobile device The relative azimuth of the two mobile devices is used to obtain the position information of the first mobile device; wherein, the first mobile device is not close to the entrance of the building, the second mobile device is close to the entrance of the building, and the second mobile device uses inertial measurement The unit locates the location information of the second mobile device. It can be seen that in order to realize indoor positioning of mobile devices, it is not necessary to lay auxiliary equipment according to a certain density, thereby reducing the complexity of the network architecture for indoor positioning.

Description

technical field [0001] The present invention relates to the technical field of positioning, and in particular, to a method and system for positioning a mobile device in an indoor environment, and a mobile device. Background technique [0002] With the increasing number of large buildings such as large supermarkets, general hospitals, airports, and parking lots, the indoor scenes are becoming more and more complex. Therefore, the demand for indoor positioning is becoming stronger and stronger. Conventional outdoor positioning methods are generally not suitable for indoor positioning. For example, the Global Positioning System (GPS) can provide high-precision positioning services outdoors, but once indoors, due to the occlusion of buildings, GPS positioning is basically invalid. However, the current common indoor positioning methods (such as Wi-Fi indoor positioning, radio frequency identification indoor positioning and infrared positioning) generally need to lay auxiliary eq...
