Image Restoration Imaging System and Restoration System, Image Obtaining Method and Restoration Method

Abstract

The application provides an image restoration imaging system, an image restoration system, an image acquisition method and an image restoration method, wherein the image restoration imaging system includes an image acquisition device, a range finder, a rotating mirror frame, a plane mirror, a target simulator and a processor , the target simulator includes an imaging device and a target; the target simulates the distance between the target object and the image acquisition device through the imaging device, and switches the optical path of the image acquisition device by rotating the mirror frame and the plane mirror, so that the image acquisition device can real-time The target object image and the target image are collected separately, so that the point spread function of the obtained target image is the same as the point spread function of the target object image, and a more accurate target object image can be obtained by measuring the point spread function of the target image Point spread function, and then restore the image of the target object according to the obtained point spread function, so that the effect of the restored image is better.

Description

technical field [0001] The invention relates to the field of image restoration, in particular to an image restoration imaging system, an image restoration system, an image acquisition method and an image restoration method. Background technique [0002] In actual optical system imaging, optical system aberrations, adjustment errors, various types of noise, nonlinear distortion of sensors, and uncertain factors in imaging links may all cause blurred images. Restoring a clear image is a deconvolution process. The core of image restoration using non-blind deconvolution is how to accurately estimate the point spread function (PSF, Point SpreadFunction). [0003] At present, the estimation of PSF can be obtained by simulation calculation of optical design software such as CODE V or Zemax, optical path difference measurement method, target method and other means. Point spread function calibration under different object distances, determine the corresponding point spread function ...
