摘　　要：陀螺作为光电吊舱的核心器件,在干扰力矩和温度等因素的作用下,启动后会发生惯性漂移,影响瞄准、跟踪或指示精度。常规漂移补偿技术需要辅助额外的设备,增大了成本和体积重量,降低了集成度。提出了一种通过对光学吊舱视场中的目标进行捕获,获得一段时间内的目标移动像元数,然后计算出陀螺方位和俯仰漂移补偿参数,根据补偿阈值进行陀螺漂移自动补偿的技术,不需要增加任何额外的设备。经试验验证,该方法可行且有效,具备工程应用价值。As the core component of photoelectric pod,gyroscope will have inertial drift after startup under the action of inter⁃ference torque,temperature and other factors,which will affect the accuracy of aiming,tracking or indication.Conventional drift compensation technology requires additional equipment,which increases the cost,volume and weight,and reduces the degree of in⁃tegration.In this paper,an automatic gyro drift compensation technology is proposed by capturing the target in the field of view of the optical pod,the number of target moving pixels in a certain period of time is obtained,then the compensation parameters of gyro azimuth and pitch drift are calculated,and gyro drift is automatically compensated according to the compensation threshold,without any additional equipment.The experimental results show that the method is feasible and effective,and has engineering application value.
