Embodiment Construction

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0033] Aiming at the problem of low positioning accuracy in existing positioning methods, this application provides a positioning method and device based on hotspot groups, the core idea of ​​which is: divide the hotspots in the positioning area into multiple hotspot groups, and Each hotspot in the hotspot determines the sampling point....

Abstract

The invention provides a positioning method and apparatus based on hotspot groups. The method comprises the following steps: dividing hotspots in a positioning area into a plurality of hotspot groups,wherein each hotspot group at least comprises two hotspots; setting sampling points corresponding to the hotspot groups; selecting a first target hotspot group; detecting whether a to-be-positioned point is matched with at least one sampling point corresponding to the first target hotspot group; if so, determining the location information of the to-be-positioned point according to the location information of the sampling point; and if not, selecting other hotspot groups for positioning. According to the method, the hotspots in the positioning area are divided into the plurality of hotspot groups, and the sampling point is determined according to the hotspots in the hotspot group, as the sampling point has correlation with the hotspots, the hotspots in the hotspot group can affect the matching result of the sampling point and the to-be-positioned point together, therefore when a certain hotspot in the hotspot group is abnormal due to external factors such as shielding or the like, thesampling point cannot be matched with the to-be-positioned point, so that the abnormal sampling point is excluded to avoid negative influence on the subsequent positioning.

Description

technical field [0001] The present disclosure relates to the technical field of terminal positioning, and in particular to a positioning method and device based on a hotspot group. Background technique [0002] With the rapid development of the mobile Internet and the continuous expansion of the demand for indoor positioning services, the fingerprint positioning technology based on hotspots has become an important research direction of indoor positioning technology. [0003] Please refer to figure 1 , which is a schematic diagram of the principle of a common hotspot-based indoor positioning technology. Depend on figure 1 It can be seen that there are 4 hot spots A, B, C, and D in the room, corresponding to multiple sampling points set at intervals. figure 1 In , the intersection of the horizontal dotted line and the vertical dotted line is a sampling point (not fully shown in the figure), and a plurality of sampling points constitute a grid of sampling points. The signal...
