激光跟踪仪已广泛应用于许多行业，以满足越来越高的精度要求。在激光跟踪仪测量中，准确的误差分析和不确定度评定是一项复杂而困难的工作。本文首先回顾了单光束激光跟踪仪的工作原理和关键技术的研究现状，并从工业界和学术界两个方面对单光束激光跟踪仪的不确定度来源进行了全面的分析。提出了一种通用的激光跟踪仪建模方法，并给出了虚拟跟踪仪的总体框架。VLS可用于测量规划、测量精度优化和不确定度评定。完成的虚拟激光跟踪系统应考虑影响坐标测量的各种不确定性源，建立与真实的系统行为一致的不确定性模型。
Laser trackers have been widely used in many industries to meet increasingly high accuracy requirements. In laser tracker measurement, it is complex and difficult to perform an accurate error analysis and uncertainty evaluation. This paper firstly reviews the working principle of single beam laser trackers and state-of-the-art of key technologies from both industrial and academic efforts, followed by a comprehensive analysis of uncertainty sources. A generic laser tracker modelling method is formulated and the framework of the virtual tracker is proposed. The VLS can be used for measurement planning, measurement accuracy optimization and uncertainty evaluation. The completed virtual laser tracking system should take all the uncertainty sources affecting coordinate measurement into consideration and establish an uncertainty model which will behave in an identical way to the real system.
