摘要
为了实现光电经纬仪动态测角精度随机误差的检测,进一步提高光电经纬仪的检测能力,进行了光电经纬仪动态测角精度随机误差的研究。基于布尔萨坐标转换原理,通过严格理论推导,得到动靶标方位值和俯仰值的理论公式。以光电经纬仪的方位角A、俯仰角E以及采样时间t等基本参数为基础,结合动靶标方位值和俯仰值的理论公式,得到A和E的理论真值,再与光电经纬仪测得值A和E进行比较,得到光电经纬仪动态测角精度随机误差。提出一种检测光电经纬仪的动态测角精度随机误差的新方法,为光电经纬仪动态测角精度随机误差的测量提供了新的思路。
To achieve measuring stochastic error for the dynamic measurement accuracy of the photoelectric theodolite and to improve detection ability of the photoelectric theodolite, a detection method of stochastic error was developed. Based on Burse-Wolf model, the theoretical equation for the angle of azimuth and elevation was developed. According to the theoretical e- quation and based on the azimuth angle, the elevation angle and the sampling time of the pho- toelectric theodolite, the theoretical truth-values of the azimuth angle and the elevation angle were obtained, and the random error was obtained from comparing the theoretical value and the measured value. A novel method for measuring stochastic error for the dynamic measure- ment accuracy of the photoelectric theodolite was presented.
