A blind deconvolution image restoration method based on phase difference relates to the field of digital image processing in a space remote sensing imaging system, and solves the problem that existing image restoration methods have limited image quality improvement space and cannot improve image quality. In this method, by building an optical imaging system, a blind deconvolution minimization model is constructed by collecting one in-focus image and at least one out-of-focus image, and the blind deconvolution minimization model is decomposed into image optimization and point diffusion The function optimizes two iterative sub-problems to solve and complete image restoration. The invention combines the phase difference method with blind image deconvolution, realizes image restoration by using multi-frame images and phase shifting technology, and fully optimizes the imaging quality of the optical imaging system with wavefront aberration disturbance, and can compensate The impact of dynamic environmental aberration disturbance on the imaging quality of the optical imaging system has a large room for image quality improvement, good robustness, and has a good application prospect and value.
Description
technical field [0001] The invention relates to the technical field of digital image processing in a space remote sensing imaging system, in particular to a blind deconvolution image restoration method based on phase difference. Background technique [0002] With the development of space remote sensing technology, higher requirements are put forward for the image quality of remote sensing imaging system. However, there are many factors that cause the image quality to decline. The existence of atmospheric turbulence makes the image quality of remote sensing images blurred, which causes great difficulties for target recognition and inference in the subsequent stage; There is relative motion between them, resulting in image motion, and the image captured is a motion blurred image; the sparse aperture optical system can realize the light weight of the space remote sensor and break through the limitation of the system caliber on the resolution, but its fill ratio is less than 1, ...
