摘要
高分辨率技术对于数字图像特征非常重要。尤其近20年来,数字成像技术大大推动了空间信息领域的发展。随着遥感应用需求的增加,获取高分辨率图像的任务非常紧迫。为了达到这个目标,我们的工作从四方面展开,分别是:空间分辨率、时间分辨率、光谱分辨率和辐射分辨率。根据不同的分辨率提出不同的成像方式,并设计了相应的原型系统。在此基础上,进行了大量的实验来验证各个成像方式的可行性。
High resolution technology is vital to digital image characteristics. Especially, in recent 20 years, digital technology promoted the development of spatial information field. As the increasing requirement, it is urgent to achieve high resolution images. For this target, we work from four parts： spatial resolution, temporal resolution, spectral resolution, radiant resolution. Then we proposed schemes for each of them with different imaging manners, designed several prototype systems and carried out many experiments to verify their feasibilities.
