| 摘 要： | 介绍了目前红外系统的目标跟踪方法；在目标跟踪时的数据关联阶段，提出了三级门限数据关联算法，根据门限级别所划分的疑似目标点位置，算法采用不同的数据关联策略。该算法能减少轨迹分叉时的计算量，能有效地检测出速度〈1像素／帧的运动点目标。实验结果证明了该算法的有效性。

| Abstract: | This paper introduces the tracking methods of infrared searching and tracking system. It brings out an algorithm of three gate levels association in the course of tracking target. According to the positions of doubtful point target divided by the levels of the gate near the forecasting point target, it adopts different ways of data association. This algorithm can decrease the calculating time and distinguish the real target whose velocity is less than one pixel per second from doubtful point target. The experiment result shows the algorithm is effective. |
