摘要:

大气的吸收和散射以及湍流效应是造成大气中长距离成像质量下降的主要原因,分析了导致图像恶化的大气因素和大气调制传递函数(modulation transfer function, MTF)。由于准确获取大气MTF是基于大气MTF的图像复原技术研究的基础,本文较系统地总结了大气湍流和大气气溶胶的MTF理论结果,给出了可能的应用思路。

关键词: 大气调制传递函数, 图像复原, 湍流, 大气气溶胶

Abstract:

The image obtained through atmosphere is degraded due to its absorption, scattering, and turbulence effects of light propagation. The modulation transfer function (MTF) of both turbid and turbulence atmospheric media, which result in image degradation, are analyzed. It is primary to obtain atmospheric MTF accurately for studying image restoration based on MTF, the theory of both atmospheric turbulence MTF and aerosol MTF are systematically generalized and some possible applied ideas are provided.

Key words: atmospheric modulation transfer function, image restoration, turbulence, atmospheric aerosol
