研制了测量用旋转靶标,靶标即可以提供以一定角速度或角加速度运动的空间仿真目标,又能够记录目标的实时空间位置,以靶标记录的数据为真值,光电经纬仪跟踪目标所测量的数据与真值比较,可得到光电经纬仪的动态测角精度。用Matlab/simulink建立了靶标仿真图,分析了靶标等速和正弦运动的规律,实现了在规定的角加速度条件下,对光电经纬仪动态测角精度的测量。 A rotating target for measurement is developed. The target can provide the space simulation target moving at a certain angular velocity or angular acceleration, and can record the real-time spatial position of the target. The data recorded by the target is a true value. The data measured by the theodolite following the target and Compared with the true value, we can obtain the dynamic angle measurement accuracy of photoelectric theodolite. The simulation chart of the target was established by Matlab / simulink, and the regularity of the target constant velocity and the sinusoidal motion was analyzed. The measurement of the dynamic angle measurement accuracy of the photoelectric theodolite under the condition of the specified angular acceleration was realized.
