Retina OCT image layering algorithm

The invention discloses a retina OCT image layering algorithm. The algorithm comprises the following steps: using a retina OCT B scanning slice image to train a model; performing inner and outer retina boundary prediction on the retina OCT three-dimensional image to obtain a rough layering result; performing alignment processing on the source input image according to the first layer and the seventh layer in the rough layering result to obtain an aligned retina OCT three-dimensional image; down-sampling the aligned retina OCT three-dimensional image to an L2 body image, and obtaining accurate layering results of a first layer, a second layer, a fifth layer, a seventh layer and an eleventh layer of the L2 body image; upsampling the accurate layering result of the L2 body image to an L1 bodyimage, and obtaining the accurate layering results of the first, second, sixth, seventh, ninth and eleven layers of the L1 body image; upsampling the accurate layering result of the L1 body image to aretina OCT three-dimensio
