摘要
将四元数相关理论应用于光电稳瞄系统的瞄准线指向研究,从四元数的角度描述了光电稳瞄系统随载体的一般三维运动,分析了载体的一般三维运动对光电稳瞄系统瞄准线的影响,结合所搭载载体的惯导数据,求解了经历载体运动后载体导航系下光电稳瞄系统要保持指示目标所需调转到的三轴姿态角度。以机载光电稳瞄系统为实例对该求解方法进行验证,仿真结果表明:使用该求解方法得出的姿态四元数结果能正确地将瞄准线矢量旋转并指示原目标。
The theory and the algorithm of the quaternion are applied in the research of the technique and the composition. Describe the EOSTS system movement from the Quaternion perspective, the influence of system motion on the line of sight is analyzed too. Then, combining with carrier IMU information, it solves the thine-axis attitude angle which EOSTS needs to achieve. Lastly, take airborne EOSTS for example, the method is verified through Matlab numerical simulation.
