Embodiment Construction

[0053] The structure of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, and the parts in the present invention that are the same as those of the prior art will be referred to the prior art.

[0054] Such as Figure 1-2 As shown, in this embodiment, an area of ​​1000 square meters (50 meters * 20 meters) is used for description. In the figure, the black line is the positioning route of this area, and the positioning accuracy is set to 5 meters; the first wireless The signal source is a wireless signal source (WIFI) or Bluetooth (BLUETOOTH) device with transmitting and receiving functions. Make sure that each device has a different BSSID address, that is, a MAC address. The SSID of the wireless signal source and the name of Bluetooth are different.

[0055] The method for indoor horizontal positioning includes the following steps:

[0056]Step L-1: Design and locate the route 100 according to...

Abstract

The invention relates to a localization method, in particular to an indoor localization method which is used for carrying out building indoor horizontal localization on a terminal and indoor vertical localization between different floors and achieving seamless handover between indoor localization and outdoor GPS localization, and belongs to the technical field of short-distance wireless communication. The method includes the steps of determining the localization line and the path point, installing a wireless signal source, building a standard single database, carrying out first localization of the terminal, carrying out secondary localization of the terminal and the like. By means of the indoor localization method, precise localization of the localization target on every floor in the building can be achieved, and the localization accuracy is high; meanwhile, seamless and quick handover of indoor-outdoor localization can be achieved through indoor-outdoor handover localization, and the localization process is continuous and free of dead space.

Description

technical field [0001] The present invention relates to a positioning method, in particular to an indoor positioning method, which is used for indoor horizontal positioning of a terminal in a building; and / or for vertical positioning of a terminal in a building indoors (between different floors); and / or for realizing indoor The seamless switching between positioning and outdoor GPS positioning belongs to the technical field of short-distance wireless communication. Background technique [0002] Among the current positioning systems, the most mature application is the Global Positioning System (GPS). However, the penetrating power of the GPS signal is very weak, and it is difficult to reach the interior of the building. When the signal is blocked or reduced, the GPS positioning will drift, and the accuracy of the GPS positioning system is about 5 meters. Therefore, for indoor positioning, GPS technology is inefficient. [0003] Since then, positioning systems based on radio...
