Eye fundus blood vessel three-dimensional reconstruction method and device, equipment and storage medium

Abstract

The invention discloses a fundus blood vessel three-dimensional reconstruction method and device, equipment and a storage medium, and the method comprises the steps: carrying out the depth prediction of OCTA two-dimensional blood vessel front projection images of different equipment through a cross-domain depth adaptive network, and obtaining a depth image prediction result; extracting the center line position and the radius length of the blood vessel on the OCTA two-dimensional blood vessel segmentation image; obtaining a three-dimensional blood vessel center line point cloud according to depth information carried by a depth map prediction result and extraction information of the OCTA two-dimensional blood vessel segmentation image; and reconstructing the three-dimensional surface grid of the blood vessel according to the three-dimensional blood vessel center line point cloud and the space parameter equation of the circle. According to the retina blood vessel reconstruction process from two dimensions to three dimensions, the problem of blood vessel space information loss in a two-dimensional front projection image, the common artifact problem in an OCTA image and the problem that blood vessels cannot be reconstructed by using three-dimensional volume data due to three-dimensional data loss and limitation of technical means are effectively solved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method, device, equipment and storage medium for three-dimensional reconstruction of fundus blood vessels. Background technique [0002] Vascular diseases are one of the most common public health problems in the world. The early clinical manifestations are not obvious, and the late sudden manifestations will pose a serious threat to the life safety of patients. However, due to the complexity and invasiveness of the current diagnostic methods for vascular diseases, it is impossible to achieve a large-scale general survey. Therefore, early screening is of great significance to the life, health and safety of the public. Clinical studies have shown that the morphological changes of retinal blood vessels are an important sign to reveal and recognize the early symptoms of many ocular and systemic diseases. As the only vascular tissue that can be obtained in the human body under non-...

AI Technical Summary

Problems solved by technology

Some public datasets do not provide 3D data, and due to manufacturer restrictions, it is difficult to output volume data from some OCTA devices, which makes it impossible to achieve 3D reconstruction of blood vessels with existing algorithms
