摘要
为解决T型架光电经纬仪精度检测难题,通过分析动态精度靶标与光电经纬仪的空间位置关系,计算出动态精度靶标编码器与光电经纬仪的方位和俯仰角度的关系式,分析误差原因并对其进行修正。根据实际检测的需要计算出三者角度变化量之间的关系,建立数学模型,同时根据T型架光电经纬仪的结构特点,设计了偏心方法对其静态精度进行检测,并在检测过程中验证了该数学模型和此偏心检测方法的正确性。
To solve precision examination problem of the T-photo-electric theodolite, the relation between the spatial location of the photoelectric theodolite and dynamic precision testing target was analyzed. The relation expressions of dynamic precision target's encoder and the azimuth and pitching angle of photo-electric theodolite was derived. The error sources were analyzed and revised. To meet the needs of actual detection, the angle variation among them is calculated.The mathematics model was established. Based on the T-photo -electric theodolite's structure feature,eccentricity method was designed to detect static precision.And correctness of the mathematics model and the method were verified.
