摘要
前视红外图像(FLIR)包含有关目标形状的丰富信息,可据以识别目标的背景干扰,从而增强抗干扰能力,且可根据目标要害部的亮度特点及预定范围,确定并进而跟踪瞄准点,本文提出目标瞄准点的序贯相关测量与Kalman滤波相结合的跟踪方法,在用110帧红外序列图像目标瞄准点跟踪仿真研究中,获得令人满意的结果,本文给出仿真误差方差、误差曲线和代表性的跟踪照片。
There is a great deal of information about the target shape in the FLIR image to identify the type of target and to recognize targets from the background and clutters. Therefor, the performances of anticlutter of the homing guidance system are enhanced. Based on the signal characteristic of the vital ports of a target and the predetermined area, the position of the target's aimoint can be obtained, measured, and tracked.
The methods which are employed to accurately determine, measure, and track the aimpoint of the targets in a sequence of FLIR image are studied. The sowlces which causes the evom of the aimhoint tiacking are analysed in this paper. A new aimpoint tracking scheme comlined by the sequential correlation measurement with the adantine kalman tietel is monosed. By using IIO IR sequential images (i.e. tracking time is about 4 sec.), we make a simulation reserch for the tracking of the ship's aimpoint. It is satisfactory that the tracking errors are x = 0.08 and y = 0.08. Forthmore, the maximal error is less then +1 pixel.
