With the rapid development of photoelectric field,photoelectric imaging system with large field of view and high spatial resolution has a wide range of application requirements.However,due to the contradiction between the large field of view and the high resolution performance of the traditional single-aperture imaging system,the size and complexity of the device will be greatly increased even if the large field of view and high resolution imaging effect can be achieved at the same time.This paper proposes a multi-aperture imaging system composed of five groups of sub-apertures,which are four groups of sub-apertures distributed around the periphery and a group of high-resolution sub-apertures that can be moved in the center.In this system,the overlapping area between multiple edge sub-apertures is used to stitch sub-images to achieve large field of view performance,and the high-resolution aperture sub-images are fused with the stitched large field of view images with variable resolution to realize the imaging system with large field of view at the same time,the performance of the high resolution and large field of view so as to solve the traditional optical system and the contradiction between high resolution problem.Multi-aperture infrared imaging system has a good development prospect and has certain research significance and important value..Based on the eagle eye vision principle,in view of the photoelectric detection platform,to explore a kind of can be in the range of wide field of target search,key regional targets at the same time automatic positioning and intelligent detection method of high resolution imaging,restrictions in order to break through the traditional photoelectric imaging devices to implement and has a wide field search,remote detection,the performance of the high resolution imaging.In the long wave far infrared spectrum,CODE V design software was used to design the optical system.In the long wave far infrared spectrum,CODE V optical design software was used to design the optical imaging system.A total of five groups of optical aperture were designed.The designed optical aperture included four groups of circumferential symmetric distribution of edge and a group of high resolution central sub-aperture.Among them,the lens surface of the central subaperture adopts spherical surface type,and the lens surface of the optical aperture with circumferential symmetric distribution of edge adopts rotational symmetric aspherical surface combined with spherical surface type,and the field of view between adjacent apertures is about 4degrees overlapping area,and the total field Angle of the system can reach 64 degrees.For the realization of the aperture optical imaging system in the central can be more exercise high-resolution subaperture intelligent control,this paper,by using target recognition algorithm for target location information,location information back to the PID controller,and through the PID control steering servo yuntai,make the central aperture of the detection area turned to the target area,to obtain high resolution image area.Symmetric distribution of the four groups in edge weeks to optical aperture joining together with large field of view image with the central optical aperture target detection by the variable resolution for high resolution images fusion area,so as to realize a picture with a large field of view and high resolution images of the target area overall output,achieved a large field of view,local areas that the performance of high resolution infrared optical imaging system.The multi-aperture infrared optical imaging system,intelligent control strategy and image processing algorithm designed in this paper have rationality and feasibility.
