摘要
随着无线通信网络和LBS的快速发展,基于位置信息的相关应用得到了广泛的发展。该文分析研究了基于距离测量的TDOA定位算法,并利用两步WLS(最小二乘法)进一步求解移动终端的位置信息;其次提出了一种基于基站定位的人数统计设计,利用基站定位所得移动终端位置信息的三维坐标进行设定,得到设定区域范围内的终端个数,从而得到设定区域内的人数。
With the rapid development of wireless communication networks and LBS,the application based on location information has been widely developed.This paper first analyzes and studies the TDOA location algorithm based on distance measurement,and uses the two-step WLS(least square method)to further solve the location information of mobile terminals.Secondly,proposing a de⁃sign of statistics of the number of people based on the location of the base station.By dividing the area,and using the three-dimen⁃sional coordinates of mobile terminals obtained from the location of the base station to determine whether they are in the area,the number of terminals in the set area is obtained,and then the number of people in the area is obtained.
