Zusammenfassung:The invention discloses a convex set projection super-resolution reconstruction method based on multiple frames of optical coherence tomography images, and the reconstruction mainly comprises two parts: firstly, collecting an optical coherence tomography scanning low-resolution image sequence; screening multiple frames of the same cross section; performing angle correction on the data set; the second part comprises the steps of establishing an image degradation model; interpolating the reference frame to a target resolution; defining a closed convex set for each pixel of the high-resolution image; residual errors are calculated pixel by pixel through a degradation model; all reference frames are introduced frame by frame for correction; and repeating for multiple times for correction. And reconstructing high-frequency information in the high-resolution image by fusing information in multiple frames of low-resolution images. The operation object of the reconstruction process is image blocks corresponding to a
