Abstract

The invention provides an image restoration method of a blurred image. The method comprises steps of: S100 acquiring a blurred image, converting the blurred image and the corresponding target blurred core from the time domain to the frequency domain, and dividing the blurred image into a plurality of blurred sub-image blocks; S200 with the preset blurred core algorithm, estimating the target blurred core of each blurred sub-image block at the same time; S300 according to the preset image restoration algorithm combined with the target blurred cores, calculating and obtaining clear sub-image blocks; S400 jointing and merging each clear sub-image block according to the order of each blurred sub-image block to obtain a clear image corresponding to the blurred image. The method can rapidly estimate the blurred core, can obviously reduce the ringing effect caused by the deconvolution operation, and improve the precision of the deconvolution algorithm.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image restoration method for blurred images. Background technique [0002] At present, human beings have entered the information age. The ability to obtain information is an important manifestation of a country's comprehensive strength. Images are a material reproduction of information that people perceive visually. Images can be recorded and stored in paper media, film, etc., which are sensitive to optical signals. on the medium. In the imaging process of a large field of view camera, there are many reasons for image blur, including image motion, defocusing of the imaging system, and atmospheric turbulence, which will cause image quality degradation, resulting in blurred image details and unclear features. The goal of the large field of view camera is to obtain high-quality continuous seamless wide-coverage images, so the acquired images need to be restored. First ...
