摘　　要：在数字测量过程中,对大型工件往往需要转站测量。转站测量过程中的各种误差都将直接影响最终的测量结果,这就需要对测量结果进行评估。结合激光跟踪仪现场测量工作,提出了一种大型工件转站测量的不确定度评定方法。In the digital measurement process,station-moving measurement is often needed for large-sized work piece.Various errors in measurement process will directly affect the results of the measurement,so the results of the measurement need to be evaluated.According to the quality control requirements of ship engine compartment in real machining using the laser tracker,this paper provide a method to evaluate measuring uncertainty of station-moving measurement for large-sized work piece.

关 键 词：测量不确定度 激光跟踪仪 转站测量
