一种基于移相技术的图像超分辨方法

探测器像元尺寸的限制已成为空间遥感成像系统分辨率提高的一个瓶颈，针对以上问题，本文提出了一种基于移相技术的图像超分辨方法。通过采用移相技术获得相对焦平面产生小于探测器阵元尺寸的微小位移的图像序列，经过图像处理后获得实际分辨率优于探测器阵元尺寸的新图像。本文搭建了实验平台，介绍了实验装置的系统组成和工作原理，给出了图像处理采用的算法，并对其进行了实验验证。实验结果表明，利用该方法图像分辨率可以提高至原图像分辨率的1．4倍。

An Image Super Resolution Method based on Phase-shifting Technology

The limitation of Detector pixel size have become a bottleneck to improve the resolution of space remote sensing imaging system, to above problems, in this paper, an image super resolution method based on phase-shifting technology is proposed. By phase-shifting technology to get image sequence with less than the size of the detector ar- ray element size of tiny displacement, after the image processing, a new image which actual resolution is better than the detector array element size is obtained. An experimental platform is built, the system composition of the experiment device and working principle are introduced, the image processing algorithms is given, and the algorithms is validated by experiment. The experimental results show that this method can increase the resolution to 1.4 times the resolution of the original image.
