Title:
EYE OCT IMAGE-BASED OPTIC CUP AND OPTIC DISC POSITIONING POINT DETECTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/159643
Kind Code:
A1
Abstract:
The present application is applicable to the technical field of image processing, and provides an eye OCT image-based optic cup and optic disc positioning point detection method and apparatus, and a terminal device. The method comprises: obtaining an eye OCT image; and detecting the eye OCT image by using a preset detection model to obtain coordinates of two positioning points of an optic cup and coordinates of two positioning points of an optic disc in the eye OCT image, the detection model comprising a first network branch and a second network branch, the first network branch being used for extracting a plurality of feature maps of different scales in the eye OCT image, and the second network branch being used for extracting the coordinates of the two positioning points of the optic cup and the coordinates of the two positioning points of the optic disc in the eye OCT image according to the plurality of feature maps of different scales. The present application achieves the accurate and efficient positioning of an optic cup and an optic disc in an eye OCT image.
