一种红外弱小目标精跟踪方法

针对红外弱小目标检测中的多帧处理技术,提出了加权的移动式管道滤波算法,解决了管道边缘噪声造成检测失败的难题。文中还将卡尔曼滤波应用于管道中心坐标的预测,实践证明,采用该方法预测精度高,可以大大地减小管道尺寸,有效地提高了管道滤波的抗噪性能、算法的实时性和精确度。

A Pricisely Tracking Method of IR Weak Target

For the channel-filter arithmetic in the serial-frame detection ofweak and small infrared targets, the article comments a method of movable channel-filter. That method has resolved the problem resulted from the noise on the edge of the channel. The article also applies Karlman channel-filter to the forecast of the center of the channel. It wasconfirmed that the method can imp rove the p recise of detection, minimize the size of the channel, and imp rove the ability of anti-noise, calculation speed and precise.
