The invention discloses a high-speed rail coordinate positioning correction method, and belongs to the technical field of positioning measurement, and the method specifically comprises the steps: 1, obtaining a rail line diagram of a high-speed rail, processing the obtained rail line diagram, and obtaining a rail angle layout; 2, acquiring feature data of the high-speed rail in real time, evaluating the position of the high-speed rail in the track angle layout according to the acquired feature data, and identifying a first coordinate of the position; 3, calculating a representative value corresponding to the first coordinate; 4, establishing a coordinate correction model, and performing real-time learning based on high-speed rail operation positioning data; 5, coordinate correction input data are obtained in real time, the obtained coordinate correction input data are input into the coordinate correction model, and a second coordinate is obtained; 6, judging whether the positioning system works normally or not, and outputting corresponding high-speed rail coordinate data according to a judgment result; by establishing a coordinate correction model, the coordinate of the high-speed rail can still be positioned in real time when the positioning system cannot operate normally.

    本发明公开了一种高铁坐标定位修正方法,属于定位测量技术领域,具体步骤包括:步骤一:获取高铁的轨道线路图,对获得的轨道线路图进行处理,获得轨道角布图;步骤二:实时获取高铁的特征数据,根据获得的特征数据评估高铁在轨道角布图中的位置,识别该位置的第一坐标;步骤三:计算第一坐标对应的代表值;步骤四:建立坐标修正模型,基于高铁运行定位数据进行实时学习;步骤五:实时获取坐标修正输入数据,将获得的坐标修正输入数据输入到坐标修正模型中,获得第二坐标;步骤六:判断定位系统是否正常工作,根据判断结果输出对应的高铁坐标数据;通过建立坐标修正模型,实现当定位系统不能正常运行时,仍能实时定位高铁坐标。
