中文摘要: 超分辨率成像已经成为红外成像技术应用中越来越迫切的需求,在军事、航空航天、民用等领域具有重要意义。虽然国内外已开展以微扫描技术为代表的超分辨率成像方法的研究,但该类方法在大幅提升红外图像空间分辨率上却遇到了瓶颈。项目受人眼固视微动模式下能够产生超视锐度(数十倍地提升人眼理论分辨率)这一视觉成果的启示,提出开展超分辨率红外成像新理论的研究。项目在模拟人眼微运动的基础上,将视场内目标的空间位置信息转换为高精度时间信息,从而获取超视锐度图像数据。主要研究内容包括:人眼固视微动特性的研究;人眼固视微动模式下的视网膜空时信息转换研究;固视微动模式下的红外成像方法及实验研究。课题的完成,在理论上将为超分辨率红外成像提供新的研究方法;在工程上将为超分辨率红外成像提供可实现的解决方案。本课题的研究成果将有效提高红外系统的目标探测、精确定位和有效识别能力,为超视锐度红外成像系统应用于军民领域提供基础性保证。

英文摘要: Super-resolution imaging has become an increasingly urgent demand in the fields of infrared imaging application.It is of great significance in the military, avigation and spaceflight, civil and other fields. Although super- reslolution imaging methods based on microscanning technology have been developed in domestic and abroad, they encounter great difficulties in obviously improving spatial resolution of the infrared image. Inspired by the vision research that the fixation eye movement can produce visual hyperacuity(the number of times to increase the theoretical resolution of the human eye),a new super-resolution infrared imaging mehtod is proposed.On the basis of simulation of human eye micro movement,the spatial location information of infrared target is converted to high precision time infromation in order to obtain hyperacuity image data.The main research contents include: human eye fixation micro movement character,retinal space-time information conversion in the condition of eye micro movement and infrared imaging method and experimental research under fixation eye movement mode.With the accomplishment of the project, it will provide a new research method for super resolution infrared imaging in theory, and a implementable solution for super-resolution infrared imaging in engineering.The research prodcut
