| 摘 要： | 提出了一种红外点目标检测算法,采用长短两个尺度的时域递归滤波器对像素灰度沿时轴进行滤波处理,然后采用动态门限分割并进行连续过门限计数,最后利用航迹关联输出确认航迹,实现了低信噪比条件下的红外点目标检测。

| Abstract: | An infrared point target detection algorithm is proposed in the paper. Two temporal recursive filters with different damped periods are used for filtering pixel intensity along time axis. A dynamic threshold is established based on the output of the filter with long period to catch and count the emerging pulses caused by the passing target, then trajectory association is used for determining the track of a point-like target. As a result, the point target is detected in low SNR. |
