摘    要:提出了一种直接从图象序列中估测运动目标到被攻击物体的撞击时间的方法,建立了目标运动的象面模型,并设计了一种利用多子区相关跟踪器和最小二乘估计方法估测撞击时间的方案。计算机仿真实验结果证明了该方案的可行性。

关 键 词:计算机视觉  景象匹配  最小二乘估计  撞击时间  尺度变化率

Abstract:Deals with the problem of a missile flying towards a land target to calculate the time of collision using passive sequence images. A scheme to estimate the time to collision of motion target directly from images is proposed, and a simple motion model for estimation is built.Then a new method based on least square solution is described, relying on the measurement from the multiple points correlation tracker. Experimental results have proved the availability of the proposed method.
Keywords:computer vision  image matching  least square solution  time  to  collision
