An outdoor rail car landmark deployment method comprises the following steps that a rail car provided with a GPS landmark surveying and mapping device is adopted to actually run on a rail, and position information of thelandmark is obtained through the GPS landmark surveying and mapping device in the actual running process; and the position information of the landmark is projected to an electronicmap, track position information is obtained, and the track position information is inputted into the landmark. Through the absolute position positioning function of the GPS, the position of the landmark can directly correspond to the position of the electronic map, and accumulation, distance measurement and other relative positioning operations are not needed. High-precision differential GPS is used to realize positioning, and the positioning precision is greatly improved. A map matching method is used, that is, longitude and latitude of position information of landmarks (points) are converted into track positions (kilometer posts) on a railmap in a point-to-line projection mode, and the precision of landmark position adjustment is also greatly improved.
一种室外轨道车地标部署方法,包括如下步骤:采用安装有GPS地标测绘装置的轨道车在轨道上实际运行,在实际运行过程中通过GPS地标测绘装置获取地标的位置信息;将地标的位置信息投影至电子地图并获得轨道位置信息,将轨道位置信息录入到地标中。本发明通过GPS的绝对位置定位功能,可实现地标位置在电子地图位置的直接对应,无需累加、测距等相对定位操作。本发明使用高精度的差分GPS实现定位,其定位精度大幅度提升。使用地图匹配的方法,即在轨道地图上将地标(点)的位置信息通过点对线的投影方式,将经纬度转换为轨道位置(公里标),其对于地标位置调整的精度也大幅度提升。
