摘要
为了解决气动光学效应所引起的红外图像偏移问题,文中采用图像离散模型泰勒级数展开的方法解决成像系统与真实目标相对运动造成的图像小变量质心偏移和角度偏移的识别运算。该方法仅使用两幅图像的数据参与运算且避免了图像质心的位置计算,处理结果表明该方法能够快速有效地计算出图像偏移参数量的数值。
In order to solve infrared image motion as the effect of aero-optics, the method is adopted to identify the small image centroid and angle motion that bases on Taylor series expansion between images and the real one in the paper. The method only deals with two images without calculating the coordinate of centroid. The result shows that the algorithm is efficient and quick to calculate the value of small image motion.
