Abstract

The invention discloses a three-dimensional positioning method and device. The method includes the following steps that: APs of which the RSSI values are greater than a certain threshold value are selected as positioning APs, and when the positioning APs are increased as much as possible, errors are decreased; with every three APs adopted as a reference site point set, a reference site point set assembly is generated according to the selected AP; APs which are not located on a plane defined by the reference site point sets are searched in each reference site point set; reference site coordinates are calculated according to the reference site point sets and the APs which are not located on the plane of the reference site point sets, namely, four APs which are not located on the same plane are adopted to perform coordinate calculation; and positioning coordinates can be obtained according to the reference site coordinates which are obtained through calculation. With the three-dimensional positioning method and device adopted, the problem that just two-dimensional plane coordinates can be obtained in the prior art can be solved. According to the three-dimensional positioning method and device of the invention, the plurality of reference site coordinates can be obtained through utilizing the plurality of obtained reference site point sets, and the positioning coordinates can be obtained according to the reference site coordinates, and therefore, system errors and computing errors can be decreased, and the accuracy of three-dimensional positioning can be improved.

Description

technical field [0001] The present invention relates to the technical field of wireless positioning, in particular to a three-dimensional positioning method and device. Background technique [0002] With the rapid increase of data and multimedia services, people's demand for positioning and navigation is increasing, especially in complex indoor environments or working environments, such as airport halls, exhibition halls, warehouses, supermarkets, libraries, parking lots, mines, etc. In , it is often necessary to determine the location information of the mobile terminal or its holder, as well as the indoor location of the facility or item. At the same time, with the widespread popularization of WIFI chips in various user intelligent terminals, such as smart phones, tablet computers and wearable smart devices, WIFI positioning technology has become one of the current mainstream and most promising positioning technology means. [0003] But at this stage, the positioning techn...
