High-speed maglev track beam precision positioning method based on free target
The invention discloses a high-speed maglev track beam precision positioning method based on a free target, and belongs to the technical field of railway surveying and mapping, and the method comprises the steps: S1, calculating the line type of a plane where a target point is located according to a deflection angle detection method; s2, converting the target point measurement coordinate system into a line coordinate system of the corresponding line type according to the plane line type to which the target point belongs; and S3, according to the line coordinate system of the target point and the position relationship between the target point and the high-speed maglev track beam, calculating the adjustment amount of the target point in the positioning process. The measuring target can be freely placed on the maglev track beam, the maglev track beam can be precisely positioned, the situation that the integrity of the track beam is damaged due to drilling in the track beam is avoided, and the operation efficiency is improved.
本发明公开了一种基于自由标靶的高速磁浮轨道梁精密定位方法，属于铁路测绘技术领域，包括S1、根据偏角检测法，计算标靶点所在的平面线型；S2、根据标靶点所属的平面线型，将标靶点测量坐标系转换为对应线型的线路坐标系；S3、根据标靶点的线路坐标系以及标靶点与高速磁浮轨道梁的位置关系，计算定位过程中标靶点的调整量。实现了测量标靶在磁浮轨道梁上自由摆放可对磁浮轨道梁进行精密定位，避免了在轨道梁上进行钻孔破坏其整体性，并且提高了作业效率。
