基于激光跟踪仪多站位布局的标准场参考点可靠性分析

Standard field reference point reliability analysis based on laser tracker multi-station layout

基于某测量现场已构建的三维坐标空间标准场,布设多站位的激光跟踪仪进行标准场参考点测量数据的采集,设计数据评估方案,并利用多源数据融合软件进行多站位测量数据的融合,利用评估方案来评估标准场参考点的可靠性。由对比分析可知,标准场中型架参考点各分量偏差及点位偏差的离散程度远大于地面参考点,且部分区域型架参考点距离值的标准偏差超出设定的阈值,可靠程度较低。

Based on the three-dimensional coordinate space standard field that has been constructed in a measurement site,this article first sets up a multi-station laser tracker to collect the measurement data of the standard field reference point,and then designs a data evaluation plan and uses multi-source data fusion software to perform multi-station measurement data fusion,and finally use the evaluation program to evaluate the reliability of the reference point of the standard field.It can be seen from the comparative analysis that the deviations of the component deviations and point deviations of the reference points of the jigs in the standard field are far greater than the ground reference points,and the standard deviation of the distances of the jigs reference points in some areas exceeds the set threshold,and the degree of reliability is low.
