摘　　要：受信号强度等因素影响,移动定位技术进行位置信息获取的方法精度受限制,需对位置定位信息进行进一步修正。目前位置定位信息修正方法主要有坐标变换法和垂直法,以香港地铁线路上的移动定位信息为实例数据,分别采用坐标变换法和垂直法进行定位结果修正探讨分析;得到了一些合理的建议,为移动定位技术提供参考。Affected by the signal strength and other factors,the accuracy of positioning method of location information with mobile positioning technology is limited,Therefore,the location information needs to be corrected. The current correction methods are mainly the coordinate transformation method and vertical method. This paper mainly discusses the basic ideas and methods of the two kinds of correction methods combined with an example of Hong Kong metro line,the correction of the positioning results was carried out with the two methods,the results are analyzed and discussed,and some reasonable suggestions are obtained,which can provide reasonable suggestions for mobile positioning technology.

关 键 词：移动定位 修正 垂直法 坐标变换法
