摘　　要：为了满足无人机对地面运动目标的侦察需求,在无人机光电侦察平台对地面运动目标实时跟踪的基础上,提出了一种对地面运动目标的光学测速方法.该方法根据光电侦察平台提供的俯仰角、方位角和无人机距离目标的距离,并结合了无人机的三维姿态信息,建立了无人机光电侦查平台对地面运动目标的速度测量模型.并分析了测速模型的误差来源,推导了误差计算公式.该测量方法无需定位目标,能够有效测量运动目标的速度,实用性较强.Based on the real -time tracking of UAV photoelectric reconnaissance platform to the ground moving target , this paper presented a method of optical velocity measurement to the ground moving target .Based on the pitch angle , azimuth angle and distance between UAV and target provided by the photoelectric reconnais-sance platform, combining with the 3D pose information of UAV, the velocity measurement model of UAV photo-electric reconnaissance platform to the ground moving target was built .The error source of the velocity measure-ment model was analyzed and the error calculation formula was derived .This method can meet demand of veloci-ty measurement of moving target in the field of UAV reconnaissance without locating the target .
