遥感图像超分辨率研究的现状和发展

卫星图像的空间分辨率是衡量卫星遥感能力的一项主要指标,也是衡量一个国家航天遥感水平的重要标志,追求更高的分辨率已成为各国卫星的发展目标。超分辨率技术在可见光遥感和红外遥感领域的实际应用,将会提高卫星的空间分辨率,也可以在保持卫星分辨率的条件下,缩小光学仪器的焦距,使卫星相机小型化,减小其体积和重量。本文从遥感应用的角度出发,讨论了超分辨率技术研究对我国遥感卫星提高分辨率的现实意义,简单说明了超分辨率的概念,论述了卫星遥感超分辨率研究的技术理论和和应用的国内外现状,重点突出了卫星采样模式的研究,提出了国内该项技术研究目前存在的不足和发展趋势。

Review of super-resolution in remote-sensing image

Satellite image's spatial resolution is a major indicator of the ability of satellite remote sensing,it's also an important symbol of a nation's space remote sensing level.The pursuit of higher resolution has become various countries' satellite development goal.The practical applications of the super resolution in visible light remote sensing and infrared remote sensing fields can improve satellite spatial resolution.It can also reduce the focus of optic apparatus,which make the satellite miniaturization(reduce the satellite's volume and weight) under the condition of maintaining satellite resolution.Embarking from the remote sensing application,this paper discussed the practical significance of the research about super resolution technique to enhance the resolution of our country's satellite remote sensing firstly.Then it simply explained the concept of super resolution,elaborated the technical theory super resolution research of satellite remote sensing and the present situations of domestic and foreign applications.Finally,it emphasized the research of satellite sampling pattern,proposed the research's domestic insufficiency existed at present and development tendency.
