Embodiment 1

[0041] Such as figure 1 As shown, the fundus OCT image fusion method provided by the embodiment of the present invention includes:

[0042] S101: Acquire N consecutively shot OCT image sequences of the fundus, where OCT represents optical coherence tomography imaging, where N is a preset value;

[0043] S102. Register the N fundus OCT image sequences to obtain the offset of the second to Nth images relative to the first image;

[0044] S103, based on the obtained offsets of the second to Nth images relative to the first image, adopt a fundus OCT image fusion network of two feature extraction branches to fuse the respective clear parts of the N images to obtain a clear Fusion result graph.

[0045] According to the method for fusion of OCT images of the fundus according to the embodiment of the present invention, N consecutively shot OCT image sequences of the fundus are acquired, where OCT stands for optical coherence tomography; the N fundus OCT image sequences are registered to obta...

Embodiment 2

[0108] The present invention also provides a specific embodiment of a fundus OCT image fusion device. Since the fundus OCT image fusion device provided by the present invention corresponds to the specific embodiment of the aforementioned fundus OCT image fusion method, the fundus OCT image fusion device can execute the above The process steps in the specific implementation of the method achieve the purpose of the present invention.

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 method and device for fusion of fundus OCT images. Background technique [0002] 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. It has the advantages of non-invasive, in vivo detection and high resolution, and has been successfully applied to the diagnosis of retinal diseases. The clinical application of ophthalmology plays an important role. But at the same time, it is precisely because of its high-resolution live detection characteristics that the OCT imaging system may cause partial blurring of the image due to the slight movement of the eyeball during the imaging process or the limitation of the imaging equipment, which will affect the final image quality. The quality of OCT images cannot meet the actual needs of identifying fine tissues in clinical diagn...
