摘　　要：针对使用高速相机对目标进行跟踪拍摄时出现的“运动模糊”以及受相机视场影响使得拍摄范围较小两个问题,提出一种基于振镜系统的高速飞行目标滚转速度测量方法.该方法利用帧差法原理完善螺旋线辅助标记法,对目标进一步标记计算.实验结果表明,该方法对场地要求低,设备搭建简单,具有成本低、鲁棒性好等优点,在较为简单的条件下依然能很好地完成目标滚转速度的测量.滚转速度测量实验平均相对误差为0.63%,小于1%的精度指标,表明该方法是可行的,精确的.Aiming at the two problems of"motion blur"and small shooting range caused by camera field of view,a method of measuring roll speed of high-speed flying target based on galvanometer system is proposed.Methods The frame difference method was used to improve the spiral assisted marking method and further mark the target.The experimental results show that this method has the advantages of low site requirement,simple equipment construction,low cost,good robustness,etc.,and can still measure the target roll speed well under relatively simple conditions.The average relative error of the rolling speed measurement experiment is 063%,which is less than 1%precision index,which shows that the method is feasible and accurate.
