Document Type and Number:
WIPO Patent Application WO/2024/093800
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of image calibration. Disclosed are an image calibration method and apparatus, an image processing method and apparatus, and an electronic device and a storage medium. The image calibration method comprises: determining an optic disk area of a target fundus image on the basis of a target fundus image; determining an effective imaging area of the target fundus image on the basis of the target fundus image, wherein the effective imaging area comprises an area in which a fundus structure is visible; and determining a calibration result of the target fundus image on the basis of the effective imaging area and the optic disk area, wherein the calibration result comprises a calibration result of a pixel unit size of the target fundus image and a calibration result of a fundus feature size of the target fundus image. In the present disclosure, a target fundus image is calibrated by means of an effective imaging area and an optic disk area, such that fundus images captured by different cameras can be compared, thereby facilitating the measurement and research of related fundus features.
