摘要 针对复杂运动条件下的空基目标跟踪器,提出了一种基于飞行器平台的运动目标跟踪系统。首先,提出了一种基于对数-极坐标(log-polar)变换的数字稳像算法。该算法对图像序列间可能存在任意角度的旋转运动、较大的缩放运动和平移运动进行运动估计和运动补偿。其次,采用了基于反向组合算法(ICA,inverse compositional algorithm)的图像对准技术对运动目标进行跟踪。真实数据的实验表明,该系统能够在复杂运动的飞行平台上对移动目标进行精确跟踪。 Against aerial tracker under complicated motion situation,a flying platform based digital stabilization and target tracking system is presented.Firstly,a novel log-polar transform based digital stabilization algorithm is presented to stabilize image sequences with arbitrary rotations,moderate scale changes and translations.Secondly,the image alignment technology based on inverse compositional algorithm is adopted to track the selected target.Experimental results on real videos demonstrate that the proposed system can track the moving ground target from a flying platform with complicated motion.
