论测量仪器的精密整平及对中技术

The precise leveling and centering technology of survey instrument

本文比较全面的阐述了用于仪器整平、对中的各种技术,给出了实现仪器精密整平、对中的方法。并分析了对中误差对不同边长的角度测量精度的影响,指出短边测量时,对中偏差会严重影响观测质量,最后展望了摆脱整平、对中问题的前景。

This paper fully discusses all kinds of precise leveling and centering technology of survey instrument and presents a quick and precise method of leveling and centering.With the analysis of angle accuracy influenced by centering error for different distances,a viewpoint is put forward that centering error can seriously deteriorate the quality of measurement in the situation of short distance.Finally,the possibility to renounce the leveling and centering process is prospected.
