摘　　要：根据航拍视频成像特点,得到相邻帧之间全局运动的六参数近似变换模型,任意帧之间的变换模型通过"帧到帧"的方式递归获得。采用角点特征匹配方法提取出有效的匹配点,实验结果表明该方法简单可靠。A global motion six‐parameter approximate transformation model is built between the adjacent frames according to the features of aerial video images .The arbitrary transformation model between the frames can be obtained through the ＆quot;frame‐to‐frame＆quot; recursion .The matching method based on corner features are used to extract the effective match points and the simulation results show that the method is simple and feasible .

关 键 词：特征匹配 全局运动估计 参数估计 动态背景
