Embodiment Construction
[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0039] see figure 1 Shown is a flow chart of a preferred embodiment of a location fingerprint information matching method provided by the present invention, which includes steps S11 to S13:
[0040] Step S11, pre-dividing the target area into M levels according to the access points in the target area; wherein, M≥2; the target area corresponding to each level is pre-divided into several sub-areas; The number of access points in the sub-area included in the above-me...

The invention discloses a position fingerprint information matching method. The position fingerprint information matching method comprises the steps that a target area is pre-divided into M hierarchies according to access points in the target area, wherein M is greater than or equal to 2; the target area corresponding to each hierarchy is pre-divided into a plurality of subareas; the access pointsin the subareas included in different hierarchies are different in number; different hierarchies correspond to different matching precisions; according to preset matching precision requirements, hierarchy matching rules are set; according to the M hierarchies and the hierarchy matching rules, obtained position fingerprint information of client-sides are matched hierarchically. Correspondingly, the invention also discloses a position fingerprint information matching device, a computer readable storage medium and a terminal device. By adopting the position fingerprint information matching method and the position fingerprint information matching device, the data size during matching calculation can be decreased, the problem of inaccurate matching caused by excessive data is prevented, and the calculation amount can be adjusted according to different matching precision requirements in a self-adaptive way.
Description
technical field [0001] The present invention relates to the technical field of wireless positioning, in particular to a location fingerprint information matching method, device, computer-readable storage medium and terminal equipment. Background technique [0002] At present, positioning based on location fingerprint information is a common method in wireless positioning. The usual method is to arrange a large number of access points in an area, and collect the signals of these access points detected by the client at different positions in the area. Intensity (RSSI value), and the collected RSSI value as the corresponding location fingerprint information, use these RSSI values to compare with the fingerprint information in the stored fingerprint database during positioning, so as to determine the current location of the client. [0003] For the collected location fingerprint information, there are two commonly used matching methods provided by the prior art: a deterministi...
