The invention relates to a track measurement data integral adjustment method based on a track geometrical state measuring instrument. According to the method, overall adjustment processing is carriedout on observation data of a total station free station and a track geometrical state measuring instrument prism; the problem that corners or abrupt changes are formed between adjacent observation stations due to independent adjustment processing of track measurement data according to an existing single observation station is solved, the influence of free station setting errors on track substationmeasurement is weakened, the relative precision between the adjacent observation stations is improved, and accurate measurement of the geometric state of the track is achieved.
本发明涉及一种基于轨道几何状态测量仪的轨道测量数据整体平差方法,所述方法将全站仪自由设站和轨道几何状态测量仪棱镜的观测数据进行整体平差处理,解决轨道测量数据按现有单测站独立平差处理所导致的相邻测站间形成转角或突变的问题,削弱自由设站误差对轨道分站测量的影响,提高相邻测站间的相对精度,实现轨道几何状态的精确测量。
