Embodiment 1
[0059] In this embodiment, the positioning area needs to be calibrated in advance, and beacon nodes are arranged in the positioning area as required, so as to at least ensure that each position requiring positioning can receive 3 or more signals. And record the attributes of each beacon node, which include: MAC, transmit power, location information, etc. Subsequent positioning needs to be used to determine the beacon node: location information, MAC; use the rasterization device to rasterize the area to be positioned to obtain grid points. In this embodiment, the upper left corner vertex of each grid is selected as the coordinates of the grid Point to rasterize the area to be positioned;
[0060] In this embodiment, it is also necessary to set up a fingerprint database for the area to be positioned in advance. What the fingerprint database reflects is the fingerprint corresponding to each grid point in the area to be positioned. The fingerprint refers to: the corresponding rela...
Embodiment 2
[0130] This embodiment provides an indoor positioning device, and its specific implementation structure is as follows Figure 5 As shown, specifically, the following modules may be included: a determination module 21, an acquisition module 22 and a positioning module 23, wherein,
[0131] Determination module 21: it is used to determine the current fingerprint anchor point; wherein, determining the fingerprint anchor point includes: obtaining no less than one grid point with the most similar fingerprint, and no less than one grid point with the most similar fingerprint Determine the fingerprint positioning point in the grid point;
[0132] Obtaining module 22: it is used to obtain the current terminal inertial vector;
[0133] Positioning module 23: it acquires the current integrated positioning point based on the current terminal inertial vector and the current fingerprint positioning point.
[0134] An indoor positioning device of the present invention also includes:
