为了实现光电经纬仪姿态测量精度的室内测试和评价,介绍了光电经纬仪姿态测量方法,依据蒙特卡罗方法对测量站的姿态测量误差源进行了分析,得出姿态测量精度的主要影响因素,进而提出了一种室内姿态测量精度检测方法。基于外场理论弹道、目标姿态以及测量站站址,通过逆姿态测量理论计算得到姿态测量原始数据,再将姿态测量原始数据输入姿态测量设备,通过比较理论目标姿态和姿态测量设备给出的目标姿态,得到姿态测量设备的姿态测量精度。依据该方法,对某型号姿态测量设备进行了姿态测量精度检测。通过实验可得到该姿态测量设备的姿态测量精度,即航向角测量误差不大于1.9°,俯仰角测量误差不大于0.4°。

In order to realize indoor test and evaluation of attitude measurement accuracy of photoelectric theodolite, an attitude measurement method of photoelectric theodolite is developed. Based on Monte Carlo method, the error sources are analyzed. Main influencing factors on attitude measurement accuracy are obtained, and a detection method for indoor attitude measurement accuracy is proposed. Based on outfield theoretical trajectory, target attitude and measuring station coordinates, the original data of attitude measurement is obtained by inverse attitude measurement theory. The original data is input into the photoelectric theodolite to obtain the test target attitude. The theoretical target attitude and the test target attitude are compared, and the attitude measurement accuracy of the attitude measurement equipment is obtained. According to this method, the attitude measurement accuracy of a certain type of attitude measurement equipment is tested. Attitude measurement accuracy of the attitude measurement equipment can be obtained by experiments. The heading angle measurement error is not larger than 1.9°, pitch angle measurement error is not larger than 0.4°.
