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

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.
