DRAWING METHOD FOR ADJUSTING DELINEATED CONTOUR, AND DEVICE AND MEDIUM

A drawing method for adjusting a delineated contour, and a device and a medium. The method comprises: determining an initial contour of a target area based on a delineation operation; determining a target path of a plurality of discrete points selected on the initial contour or a contour of the target area; and in the target path, determining a target curve segment between each pair of two adjacent discrete points among at least one pair of two adjacent discrete points, and adjusting the initial contour on the basis of the target curve segment, so as to acquire a target contour (S108), wherein during the determination of the target curve segment, two discrete points, other than two adjacent discrete points, in the target path are acquired to serve as two auxiliary points, two discrete point sets are determined, an arc-shaped deployment curve segment corresponding to each discrete point set is determined on the basis of each discrete point set, and deployment is performed on the basis of two deployment curve s
