摘　　要：本文首先提出了一种基于圆投影向量的目标分布描述模型,并采用修正Bhattacharyya相关系数来定义参考模板与目标模板间的距离;然后利用均值平移算法来完成目标的搜索,考虑到平台运动,本文对搜索窗口进行相应的定义;最后将其与粒子滤波算法结合起来实现红外目标跟踪。实验结果证明,本文方法不仅能够准确的跟踪目标,且对目标被遮挡以及平台运动等具有鲁棒性。Firstly,a distributing model of target was proposed based on the circular projection vector, and the modified Bhattacharyya coefficient was defined to represent the range between the referenced and target＇ s template. Secondly, the mean shift algorithm was adopted to search the target ; and the paper defined the search window considering the movement of the platform. Lastly, infrared target tracking was actualized by particle filter. The experimental results show that it can not only track the target accurately, but also be robust to the sheltered target and platform＇s movement.
