Abstract

A direct method for assessing the influence of the atmosphere on scanner signals is examined. The making of such assessments assumes the availability of two matched images of the very same sector of the Earth's surface recorded at different viewing angles in the very same spectral range. The results of assessment of the transfer coefficients and background levels formed from the images registered using intermediate-and high-resolution scanners are presented. The values of these assessments were used in atmospheric correction of the original images.

多光谱扫描仪图像分析中的大气校正参数
研究了一种评估大气对扫描信号影响的直接方法。进行这类评估的前提是,在地球表面完全相同的区域,在完全相同的光谱范围内,以不同的视角记录了两张匹配的图像。介绍了利用中分辨率和高分辨率扫描仪对图像进行配准后形成的传递系数和背景水平的评估结果。这些评估值被用于原始图像的大气校正。
