摘要
为了通过低分辨率红外探测器获取高质量的图像信息,对基于微扫描成像的序列图像获取方法和超分辨图像重建算法进行了研究。首先,阐述了微扫描红外成像系统工作模式和软硬件构成。然后,提出了一种基于电机驱动的光学微扫描序列图像获取方法。最后,提出了一种基于字典学习的凸集投影算法用于超分辨图像重建。采用数值仿真和实际拍摄两种方式来验证本文算法的有效性,结果均表明本文方法能够有效地重建图像边缘细节并对噪声有较好的抑制作用。
In order to acquire high quality image information through infrared detector with low resolution,a method for acquiring image sequence through a Micro-scanner Imaging(MSI)system and Super-resolution Image Reconstruction(SRIR)algorithm was investigated.First,the working mode,hardware and software composition of the MSI system were elaborated.Then,the method for acquiring the image sequence from the MSI system based on motor drive was extracted.Finally,an algorithm of Projections onto Convex Sets(POCS)based on dictionary learning was presented,which was used for SRIR.To validate the proposed method,low resolution image sequence was acquired from digital simulation and real shooting.Experimental results indicate that the proposed method could effectively restore the edge information of an image and suppress noise.
