The invention discloses an offset image stabilization-based super-resolution imaging system and method. The offset image stabilization-based super-resolution imaging system comprises a system imaging group mirror, a spectroscope, a high-frame frequency detector, a high-resolution imaging detector and a data processor. Parallel light is divided into two paths on the surface of the spectroscope after being aggregated by the system imaging group mirror, and imaging is carried out on one path by the high-frame frequency detector; the data processor is used for calculating a displacement compensation value according to image data; and a driving device is used for driving an imaging surface of the high-resolution detector to move the displacement compensation value.
Description
technical field [0001] The invention relates to the field of space-based imaging, in particular to a super-resolution imaging system and method based on offset image stabilization. Background technique [0002] With the demand for higher and higher resolution of ground imaging, in addition to technical development in optical system design, super-resolution imaging technology is considered to further improve the overall resolution of satellite ground imaging in terms of system design. [0003] Super-resolution reconstruction technology uses the redundancy, similarity and some prior knowledge between low-resolution image (LR) sequences for data fusion to reconstruct an image (HR) with a higher spatial resolution, while removing the image Noise, Blur, etc. The method based on reconstruction refers to de-degrading the degraded image according to the image degradation model and using a certain mathematical theory to obtain a super-resolution reconstruction image, such as frequen...
