介绍了超分辨率重构技术的基本原理及实现方法,分析了限制航空图像分辨率提高的主要因素。首先,依据工程应用需求列举出了3种可应用于航空光电成像系统的典型超分辨率重构技术;然后,着重讨论了错位误差对亚像元成像技术重构效果的影响,并通过仿真实验加以分析;最后,通过对发展现状的调研及工程应用需求的分析,对未来航空光电成像系统中应用超分辨率重构技术的发展方向进行了展望,具有一定的参考价值。

The principles and basic methods of realizing super-resolution reconstruction are introduced, and the restrictions on increasing the resolution of aerial images are analyzed. According to the requirements of applications, three typical super-resolution techniques which can be used in applications are listed, and then we focus on the relationship between dislocation error and quality of reconstruction image in the sub-pixel imaging technique through simulation. Finally, we consider the development situation and application requirements, the further application prospect of super-resolution in the aerial E-O imaging system, which can really make a difference.
