Research and Analysis on Segmented Integral Ranging Correction Method Based on Laser Tracker

针对装配现场难以实现恒温测量的情况,以对测距影响较大的温度因子为研究对象,提出激光跟踪仪分段积分测距改正方法,建立分段积分测距改正模型。基于Radian激光跟踪仪进行单测线温度测距改正实验,结果表明,该方法能够有效地减弱温度梯度的影响,为装配现场的测距温度梯度改正提供理论支撑,有助于提高飞机等装配制造的精度。

We are concerned with the difficulty of constant temperature measurement in the assembly site,which has a great influence on distance measurement.In this paper,a correction method for laser tracker segmented integral distance measurement is advanced,and the correction model of segmented integral distance measurement is established.Through the single line temperature ranging correction experiment,based on radian laser tracker,the experimental results show that the method can effectively reduce the influence of temperature gradient,provide theoretical support for the temperature gradient correction of the assembly site,and help to improve the accuracy of aircraft and other assembly and manufacturing.
