Abstract

The invention provides a staring super-resolution imaging device and method, and aims at solving the problem of low resolution of an existing imaging device. The device comprises an imaging device lens group (1), a detector (2), a detector driving platform (3), a driver (4), a storage device (5), an image processing circuit (6) and an image display circuit (7), wherein the detector (2) is arranged in a focal plane on a light path of the imaging device lens group (1); a drive part of the driver (4) drives the detector driving platform (3) to generate movement with magnitude and direction being random values. The imaging method comprises the following realization steps: a change number instruction is set; the driver (4) drives the detector (2) to do corresponding number of random jitter; a light signal is imaged on the detector (2) through the imaging device lens group (1) to obtain a low-resolution image with a frame number corresponding to a change number; the low-resolution image is rebuilt by the utilization of a variational Bayesian algorithm. The staring super-resolution imaging device and method are suitable for video reconstruction and satellite photography.

Description

technical field [0001] The invention belongs to the technical field of super-resolution imaging, and in particular relates to a staring super-resolution imaging device and imaging method for multi-frame image acquisition and reconstruction, which can be used for video reconstruction and satellite shooting. Background technique [0002] Improving the resolution of the optical imaging system is the relentless pursuit of image science research and its engineering applications. In addition to improving the resolution by improving the performance of imaging system-related components, such as optical system focal length, aperture and detectors, you can also choose Adding suitable optical devices to the imaging system can improve the resolution, but adjusting the structure of the imaging system will lead to the complexity of the system and a large increase in tasks to a certain extent, so how to restore or reconstruct super-resolution based on existing imaging equipment Image has b...
