| 摘 要： | 针对无人机编队视频序列中的多目标精确跟踪的要求,使用STK三维建模软件模拟无人机编队飞行视频,通过双差分图像操作、多分辨率连通分支标记算法确定图像中的运动区域.提出了一种改进的贪婪算法,利用已确定的矩形运动区域作为初始轮廓,实现对无人机目标的精确轮廓提取.以运动区域的中心位置为输入,建立在线卡尔曼滤波器组对多目标进行跟踪,并由此提出了如何对多目标中的遮挡问题进行判定、分割的方法.仿真实验验证了文中提出的方法.

| Abstract: | Aiming to meet the requirements of multiple targets accurate tracking of UAV(unmanned aerial vehicle) formation video sequences,STK-3D modeling software was utilized to simulate the UAV formation flight video and capture the moving regions by means of a double difference operator and multi-resolution connectedness label operator on simulation video.By using rectangular moving regions as an initial contour,an improved greedy algorithm was proposed to realize the accurate contour drawing of the UAV targets.Th... |
