摘　　要：基于红外多孔径成像系统,提出了一种兼顾局部高分辨与大视场的变分辨率图像重构方法。首先,借助三维动态红外场景软件,完成了红外多孔径成像建模与仿真;其次,采用像素重排算法,实现低分辨率单元图像变分辨率大视场重构;最后,利用PSNR及图像清晰度函数对重构结果进行讨论分析。实验表明,本文的研究成果在扩大探测视场的同时显著提高成像的分辨率,可以对红外多孔径成像系统设计及应用提供理论指导。Based on multi-aperture infrared imaging system, a new reconstruction method which a- chieves both variable-resolution and large field of view is proposed. Firstly, a muhi-aperture imaging system is modeled and simulated by using 3D infrared dynamic rendering scene software. Secondly, pixels closely arrange reconstruction method is proposed which can reconstruct variable-resolution and large field of view image from sub-image arrays. Finally, an evaluation of the reconstructed image quality is presented to discuss the significant factors affecting the final result. Experimental results show that the recon- structed image expands the detection field of view, and significantly improves the imaging resolution, which can provide theoretical guidance for the design and application of multi-aperture infrared imaging system.
