经纬仪对准动态靶标的方法研究

Study on the Method of Aligning Theodolite with Dynamic Target

动态靶标是一种在室内检测光电跟踪测量设备的装置,经纬仪在检验各项精度指标或调试伺服跟踪系统前都需要动态靶标和经纬仪的相对位置满足动态靶标按预定轨迹旋转一周,经纬仪通过调整方位和俯仰姿态都能够捕获到靶标(简称经纬仪对准动态靶标)。首先介绍了传统的经纬仪对准动态靶标的方法,指出了其四方面的局限性,进而提出一种应用角度测量指向装置的经纬仪快速对准动态靶标方法,阐述了该方法所用角度测量装置的具体结构和对准靶标的具体实现过程,接着对应用角度测量装置对准靶标的主要误差进行了分析,最后总结了这种方法的优势。具体使用结果表明,该方法可以显著提高经纬仪对准靶标的工作效率。

Dynamic target is an indoor equipment using for examining electro-optical tracking devices.It＇s need to align the optical drawtube of theodolite by adjusting the azimuth and pitch attitude with dynamic target which is rotating in a schedule circle before degugging the servo tracking system of theodolite or examining accuracy index of theodolite.This article first introduces the traditional method of aligning optical drawtube of theodolite with dynamic target,points out its limitations,and further,proposes a fast approach of aligning theodolite with dynamic target by using a new angle measurement instrument.The structure of the angle measurement instrument is described in detail and the concrete process of aligning dynamic target is presented.Then this article makes the error analysis and summarizes the advantages of this new method.The specific using of this new approach shows that this method can significantly improve the efficiency of aligning theodolite with dynamic target.
