Research On Target Ranging And High Resolution Image Reconstruction Based On Multi-aperture Imager

With the development of science and technology, the traditionalsingle-aperture infrared imaging systems can not meet convenient, flexible andaccurate detection needs in the modern battlefield. Multi-aperture infrared imagingis a new imaging method combining compound eye concept.It has small size, largeview of field, passive target ranging and positioning, high-resolution imagesreconstruction and other advantages. Multi-aperture imaging system will play animportant role in modern battlefield.This paper focuses on the target ranging and high-resolution imagereconstruction based on multi-aperture infrared imaging system. First, according tothe concept of compound eyes, a multi-aperture infrared imager is modeled andsimulated by using3D infrared dynamic rendering scene software developed by ourgroup; Second, based on stereo vision ranging principle, the detailed design,verification and comparison of binocular and multiaperture stereo ranging methodhas been finished; Finally, the study of high-resolution image reconstructionmethods and simulation has been completed by using pixel rearrangement method.
