摘要
针对舰载光电设备的方位轴在摆扫时受到船摇影响,造成视轴不稳定问题,改进了基于旋转矩阵的轴角补偿算法,推导出摆扫状态下光电设备的俯仰轴角在地理系下维持稳定的关系式。利用仿真软件搭建算法模型并进行了仿真,仿真结果表明,改进后的轴角补偿算法能补偿船摇对舰载光电设备俯仰轴角的影响,从而证明改进后的轴角补偿算法的有效性。
The azimuth axis of shipborne optoelectronic equipment is affected by ship rolling during swinging and sweeping,resulting in the instability of visual axis.An improved algorithm of axis Angle compensation based on rota-tion matrix is proposed to derive the relationship between the pitch axis Angle of photoelectric equipment and its sta-bility in the geological system under the state of swing sweep.The simulation results show that the improved axis An-gle compensation algorithm can compensate for the influence of ship rolling on the pitching axis Angle of shipborne optoelectronic equipment,thus proving the effectiveness of the improved axis Angle compensation algorithm.
