Focus area extraction method and device, electronic equipment and readable storage medium

The invention relates to the technical field of focus detection, and discloses a focus area extraction method and device, electronic equipment and a readable storage medium. The method comprises the following steps: acquiring to-be-detected image data, the to-be-detected image data comprising a real focus area; analyzing the to-be-detected image data, and determining a region of interest corresponding to the real focus region; extracting feature information of the region of interest, and generating a focus initial contour according to the feature information; and adjusting the initial contour of the lesion to obtain a target contour completely coincident with the real lesion area. By implementing the technical scheme of the invention, automatic extraction of the initial contour of the lesion is realized, manual drawing according to each layer of section is not needed, the time cost of determining the lesion area is reduced, and the extraction efficiency of the lesion area is improved; the central point of the
