为了解决光电跟踪系统中高速运动目标快速识别、准确定位的问题,在深入研究相关跟踪算法的基础上,提出了一种基于分块模板相关跟踪与自适应波门相结合的快速跟踪算法,该算法利用分块矩阵与大模板矩阵之间的关系,得出了在四分块的情况下,计算量为原来的1/4,搜索范围为原来的4倍,大大提高了计算速度和搜索范围,且具有原始相关算法的高的跟踪精度,可以实时快速的跟踪上高速运动目标。

To meet the special demands of electro-optical tracking system for rapid recognition and accurate positioning,a fast identification and location algorithm is required.Through the in-depth characteristics analysis of the correlation tracking algorithm,a block-based correlation tracking template combined with adaptive window fast tracking algorithm was proposed.The relationship of block Matrix and the large pattern matrix is used for the improved algorithm.The amount of computation is 1/4 of the original.The searching range is 4 times of the original under the condition of four blocks.The computational speed and searching range was improved by the improved algorithm and it has high precision of the original.The fast moving target was real-time tracked by the improved algorithm with high-speed.
