| 摘 要： | 为满足列车运行控制及列车定位不同层次的需求,将轨道地图数据分为轨道专用数据、轨道线路数据及地形环境数据,并对轨道地图线路数据按照不同尺度划分为特征点层及插值点层,形成列控轨道地图结构.针对原始GPS地图测量数据,采用多点加权距离检验及Kalman估计差值检验实现错误数据剔除;根据轨道曲线特征对原始数据进行划分,通过在各...

| Abstract: | To meet different level requirements of train positioning and control,the track map data for train control consists of private data,track data and terrain environment data,and the track data are divided into feature layer and interpolation layer under different scales,which could contribute to complete structure of the track map.To huge GPS measurements,the multi-points weighted distance discrimination and Kalman estimation are applied to reject incorrect data;with improvement of Douglas-Peucker method,in w... |
