摘要
将压缩感知理论引入超分辨率成像,得益于绝大多数图像普遍具有稀疏性,提出了一套基于4f系统的全相位反射式压缩编码孔径光学成像系统,采用反射式空间光调制器进行光学系统成像实验,通过MATLAB程序对该系统进行仿真,对采集到的单幅低分辨率图像进行解码重建得到高分辨率的。实验结果表明,只有在保证CCD相机与空间光调制器像元尺寸完全匹配的情况下才能得到最佳的重建效果。
Abstract
Compressive sensing theory is led to super-resolution imaging technology for the general sparsity of most images, and an optical imaging system with all phase reflective compressive coded aperture is proposed based on 4f optical system. Reflective space optical modulator is used to perform optical system imaging experiments and the system is simulated through MATLAB program, the images with high resolution is obtained through decoding and reconstructing the collected single frame image with low resolution. Experimental results show that the best reconstruction effect can be obtained at the condition of ensuring CCD camera matching to spatial optical modulator pixel size completely.
