Abstract

The invention provides a point set-based position information acquisition method and device. The method includes the following steps that: the coordinates of a plurality of position points of a mobile terminal at a geographic location to be measured are obtained, so that a first point set can be formed; the average value of the coordinates of all the position points in the first point set is calculated, so that the coordinates of a first center point can be obtained; the linear distances from the first center point to all the position points in the first point set are calculated; screening is carried out according to a preset noise point proportion, so that position points in the first point set which have the farthest linear distances to the first center point are removed, the remaining position points form a second point set; and the average value of the coordinates of all the position points in the second point set is calculated, so that the coordinates of a second center point can be obtained, and are adopted as the location information of the geographic location to be measured. With the above noise point removal means, the accuracy of the center point can be effectively improved, and therefore, the problem of large data error caused by external interference in the prior art can be solved.

Description

technical field [0001] The present application relates to the field of wireless communication technologies, and in particular, to a method and device for acquiring location information based on point sets. Background technique [0002] Positioning technology refers to determining the actual location information of mobile users through the cooperation of wireless terminals and wireless communication technologies. The basic principle is that the mobile target interacts with multiple fixed base stations (ground or air) with known coordinate positions to obtain corresponding measurements After parameters, use appropriate processing methods to obtain the position of the moving target in space. Existing positioning technologies mainly include: Global Positioning System (GPS, Global Positioning System) technology, GLONASS (Global Navigation Satellite System) technology, BeiDou Navigation Satellite System (BDS, BeiDou Navigation Satellite System) technology , Galileo (Galileo, Gali...
