Abstract

The embodiment of the invention relates to the technical field of image recognition and discloses a fundus macula locating method, device and system and a storage medium. The method includes the stepsof determining a visual disc area in a fundus image, at least one candidate macular area and the confidence coefficient of each candidate macular area; determining a to-be-determined macular range onthe basis of the visual disc area; screening out one or more candidate macular areas in the to-be-determined macular range from the candidate macular areas; determining the candidate macular area with the maximum confidence coefficient among the candidate macular areas in the to-be-determined macular range as a macular locating area. By means of an image recognition model, the method has the advantages of small time consumption and high applicability and working efficiency. The visual disc area is obtained through the image recognition model, and then the accuracy rate of determining the macular locating area is greatly improved on the basis of the visual disc area.

Description

technical field [0001] Embodiments of the present invention relate to the field of deep learning technology, and in particular to a method, device, system and storage medium for locating fundus and macula. Background technique [0002] The macula is an important physiological structure of the fundus and the optical center of the human eye. In fundus images, macular center localization is of great significance for the detection of diabetic retinopathy. The distance between the lesion area and the center of the macula determines the degree of impact on human vision and the severity of the lesion. Therefore, it is of great significance for macular localization. In traditional technologies, image processing methods are generally used to locate the macula, and the macula is located by features such as brightness and shape in the image or the positional relationship of physiological structures. These features will all be manually selected. The positioning of the macula depends...
