摘　　要：激光跟踪仪多台联用或单台转站的本质是构建统一空间测量场,而测量场构建最重要的就是各个坐标系的建立和转换,其转换均通过公共点进行桥接。研究了实现同一公共点在不同坐标系下的坐标值统一到全局坐标系下的过程,探讨了跟踪仪现场测量结果不确定度的来源与测量数学模型。通过转站实验验证了跟踪仪现场测量结果(L=10m、20m、30m、40m、50m、60m)的不确定度,为后续现场测量不确定度的分析研究工作提供了有力支持。The essence of using multiple laser trackers in combination or a single station is to construct a unified spatial measurement field,and the most important aspect of constructing a measurement field is the establishment and conversion of various coordinate systems,which are bridged by common points.The article studied the process of unifying the coordinate values of the same common point in different coordinate systems to the global coordinate system,and explored the sources of uncertainty in the on-site measurement results of the tracker and the measurement mathematical model.The uncertainty of the on-site measurement results of the tracker(L=10m,20m,30m,40m,50m,60m)was verified through station transfer experiments,providing strong support for the subsequent analysis and research of on-site measurement uncertainty.
