摘  要:目前对地遥感的最主要途径之一便是通过遥感相机获得目标物信息,然而遥感相机的分辨率直接影响成像质量。结合遥感相机的推扫式成像技术,文章提出了一种基于单像素成像的超分辨增强技术模型,该模型能够简化重建过程,其设计目标是基于单像素超分辨的技术手段将航天遥感相机的图像分辨率增强4倍。为了验证该设计思想及其重建效果,文章设置了超分辨增强仿真试验,最终仿真试验结果表明,基于单像素的超分辨模型可以将图像的信噪比提高1.1倍,且重建的图像具有明显的抑制噪声的效果,起到了良好的降噪功能,相较于其他传统图像分辨率增强方法(如双三次内插、超深超分辨神经网络)具有更高的优越性。该方法可为地理遥感探测、土地资源探查与管理、气象观测与预测、目标毁伤情况实时评估等诸多领域的图像处理和应用提供有力支持。At present,one of the most important ways of earth remote sensing is to obtain target information through remote sensing cameras,but the resolution of remote sensing cameras directly affects the imaging quality.Combined with the pushbroom imaging technology of remote sensing camera,this paper proposes a super-resolution enhancement technology model based on single-pixel imaging,which can simplify the reconstruction process,and its design goal is to enhance the image resolution of aerospace remote sensing camera by 4 times based on single-pixel super-resolution technology.In order to verify the design idea and its reconstruction effect,the super-resolution enhancement simulation experiment is set up,and the final simulation results show that the single-pixel super-resolution model can improve the signal-to-noise ratio of the image by 1.1 times,and the reconstructed image has the obvious effect of suppressing noise,which plays a good noise reduction function,and has higher superiority than other traditional image resolution enhancement methods(such as bicubic interpolation and ultra-deep super-resolution neural network).This method can provide strong support for image processing and application in many fields,such as geographic remote sensing detection,land resources exploration and management,meteorological observation and prediction,and real-time assessment of target damage.
