Resolution Improvement and Data Processing of Remote Sensing Images
摘要
光电成像系统通常为典型的光学-离散采样成像系统,可通过增加成像系统物镜的焦距,增加探测器阵列的规模,减小探测器单元的几何尺寸并提高探测器的占空比等技术途径来提高系统的分辨能力。在现有的探测器和光学系统下,有效的图像数据处理可提高成像系统的分辨率。主要介绍了近年来备受国内外关注的基于离散面阵CCD/CMOS探测器的亚像元成像技术以及超分辨率图像处理技术。
Abstract
An electro-optical imaging system is a typical optical-discrete sampling system. Usually, the spatial resolution of the electro-optical imaging system can be improved by means of the technical routes such as the increase of objective lens focal length, the increase of detector array consumption, the size reduction of detector elements, and the increase of detector filling rate. Due to the restriction of device level,the effective data processing method can be used to improve the resolution of an imaging system. The sub-pixel imaging technique and the super-resolution image processing technique based on the discrete CCD/CMOS plane array detectors are mainly introduced, which are widely concerned at home and abroad.
