%X 针对安装于方位、俯仰(AE)旋转平台的测量设备，通过分析配件6自由度方法建立了完整的制造和安装误差模型并给出了刚体模型指向角解析算法。算法消除了传统近似算法存在的轴偏离误差、高仰角误差等算法误差，且无需校准望远镜的机械安装误差、无需人工或自动读数。基于这种解析算法，提出一种通过非线性方程组数值求解获取指向角度标校参数的方法，在显著降低系统设计制造难度的前提下有效提高了标校精度。<br />
For the measuring device mounted on Azimuth-Elevation rotational platform, integrated making &amp; assembling error model is set up by six freedom analysis for an assembly, the Pointing Angle analytical algorithm for the rigid model is given as well. By the analytical algorithm, such traditional errors as axis-deviation error and high-elevation error are eliminated, and do not need to calibrate the assembly error of telescope, and do not need manual or automatic reading. A method that acquires the parameter for pointing angle calibration is proposed by numerical solving for system of nonlinear equations. This method can effectively improve the calibration accuracy under the premise of significantly reducing the difficulty of system design and manufacturing.
