Abstract

The invention provides a fundus OCT (optical coherence tomography) image fusion method and device, which can solve the problem of local blurring in fundus examination. The method comprises the steps of obtaining N fundus OCT image sequences which are shot continuously, wherein the OCT represents the optical coherence tomography imaging; registering the N fundus OCT image sequences to obtain the offsets of the second image to the N-th image relative to the first image; and on the basis of the offsets of the second image to the N-th image relative to the first image, fusing the clear parts in the N images by adopting the fundus OCT image fusion networks of two feature extraction branches to obtain a clear fusion result image. The invention relates to the technical field of fundus imaging.

Description

technical field [0001] The invention relates to the technical field of fundus imaging, in particular to a fundus OCT image fusion method and device. Background technique [0002] Optical coherence tomography (Optical Coherence Tomography, OCT) technology is a new type of non-destructive optical imaging technology in the field of modern biomedical imaging in recent years. Clinical application in ophthalmology plays an important role. But at the same time, it is precisely because of its high-resolution live detection feature that the OCT imaging system may cause partial blurring of the image due to slight movement of the eyeball or limitations of the imaging device during the imaging process, which will affect the final image quality. High-quality OCT images cannot meet the actual needs of distinguishing fine tissues in clinical diagnosis. Therefore, how to ensure effective suppression of local blur while minimizing the impact on image detail structures has become an importa...
