摘要 在对由气动光学效应引起的图像模糊进行理论分析的基础上,提出了用最小二乘法(LS)对气动光学效应降晰函数进行辨识的方法。利用所建的模型对试验图像进行图像复原,提高了复原图像的信噪比,减小了复原以后的图像误差。 Based on the theory of the blurred image of aero-optics effect, a least-square (LS) method was used to identify the point spread function (PSF) and to recover the blurred image. The SNR (signal noise ratio) is improved, and the error is reduced, and an obvious result is achieved.
