Super-resolution imaging system and method with stable images

Abstract

The invention provides a super-resolution imaging system and method with stable images. The method comprises the following steps: firstly, placing an imaging optical element group, an oscillating mirror, a spectroscope, an imaging lens group and an imaging camera sequentially in the imaging optical path direction of a propagation path of an observed aiming beam; connecting an input end of a super-resolution image synthesis unit, which is used for synthesizing a plurality of undersampled images transmitted by a receiving and imaging camera into super-resolution images, with an output end of the imaging camera; placing the imaging optical element group, the oscillating mirror, the spectroscope, a detecting lens group and a detecting camera sequentially in a detecting optical path direction of the propagation path of the observed aiming beam; connecting an output end of the detecting camera with an input end of a computing control unit; connecting an input end of an oscillating mirror driver with an output end of the computing control unit; connecting an output end of the oscillating mirror driver, which is used for amplifying the voltage analog quantity sent by the computing control unit into the driving voltage analog quantity of the oscillating mirror and outputting the driving voltage analog quantity to the oscillating mirror, with a driving end of the oscillating mirror.

Description

technical field [0001] The invention belongs to the field of high-resolution imaging, in particular, it relates to an image-stabilized super-resolution imaging system and method. Background technique [0002] Photoelectric imaging is an important technical means for human beings to obtain visible and infrared multispectral image information, and it is widely used in various fields of national economy and national defense construction. The resolution of an optoelectronic imaging system generally refers to the smallest detail that can be resolved after the image passes through the system. It is an important technical index that characterizes the detection capability of the system. The main factors affecting this index are the aperture size of the imaging lens and the geometric parameters of the image sensor. Limited by physical conditions, the resolution of images obtained by people is low, and these low-resolution images cannot well meet the actual needs, especially in the fi...

Problems solved by technology

However, no matter which type of micro-scanning technology can overcome the image jitter in the detector sampling integration time caused by the residual jitter of the system platform attitude control, that is, the system platform jitter directly affects the resolution of a series of under-sampled image sequences obtained by micro-scanning. Then affect the super-resolution reconstruction of the observed field of view
