Super-resolution method for calibrating micro-scanning image based on optical system

Abstract

The invention discloses a micro-scanning image super-resolution calibration method based on an optical system. The method comprises the following steps: step 1, optical system calibration; 2, micro-scanning super-resolution processing is carried out; in the first step (4), the overall point spread function obtained through calculation of the inclined edge method serves as an initial value and is transmitted to the blind deblurring algorithm, and the point spread function of each image block is calculated. According to the invention, the problems of poor super-separation effect and artificial effect caused by splitting of a physical optical system are solved; according to the method, the concept of combining the inclined edge method and the blind deblurring based on the image blocks and modeling the physical optical system and reconstructing the image blocks is adopted, so that the problem of inconsistent point spread function space easily caused by factors such as field of view, aberration, distortion and the like of the optical system is solved, and the accuracy of a super-resolution result is improved; according to the method, the problem of inaccurate blind deblurring result is solved by utilizing the similarity of the point spread functions of the symmetric image blocks, and the calibration robustness of the optical system is improved.

Description

Technical field [0001] The present invention relates to the field of optical imaging, in particular, based on optical system standard micros scan images super resolution method. Background technique [0002] In recent years, with the large area of ​​imaging equipment, the clarity of imaging has also put forward higher requirements, and due to the high cost of upgrading hardware, the image resolution is improved by improving the optical system, where micro-scan Surgery technology can obtain the same or even higher imaging effect while saving costs, but the existing micros scan image is super-resolution, and its parameter setting is complex, and the splitting of physical optical system is not good. And there is an artificial effect; existing micros scan image super resolution method, due to the factors of optical system, aberration, distortion, etc. The result is not accurate. Inventive content [0003] It is an object of the present invention to provide a problem based on an opti...
