摘　　要：利用无人机可见光载荷实现地面运动目标的搜索是获取地面运动目标信息的重要技术。为实现在探测器运动的条件下实现运动目标的检测,提出了一种基于平面+视差的运动目标搜索方法。首先采用相位相关法配准寻找主平面,实现对运动图像的全局运动补偿,然后采用光流法对残差图像进行视差滤除。全局运动补偿可以有效补偿主平面的运动,视差滤除通过多视角理论,去除视差景物在搜索系统中形成的虚警。实验表明,该方法利用可见光载荷系统,通过对移动探测器的运动补偿和视差的滤除,能够很好地实现地面运动目标的搜索,提高地面运动目标信息获取的能力。The ground moving target detection using the visible payload is an important technology to obtain information of the ground moving target. To detect the moving target on the moving camera, a method within the ＂Plane＋Parallax＂ framework is proposed to detect the moving target in video sequences observed hy a moving camera. Firstly, the reference plane is found by the image registration based on phase-correlation and the global motion compensation is achieved. Secondly, the parallax regions are filtered by the optical flow method. The global motion compensation can effectively compensate for the motion of the main plane and the parallax in the search system is removed by the multi view theory. The experiments show that this method can achieve the moving target detection using the visible payload through the motion compensation and parallax fiher and improve the ability to obtain the ground moving target.
