Line break point determination method and device, equipment and storage medium

The embodiment of the invention discloses a line break point determination method and device, equipment and a storage medium. The line break point determination method comprises the steps of sampling a hand-drawn line according to a preset sampling frequency to obtain first sampling points, grouping the first sampling points according to a distance between adjacent first sampling points, and for each group, merging the first sampling points according to position information of the first sampling points in the group to obtain a first target point, and determining a break point of the hand-drawn line according to the curvature of the first target point. According to the line break point determination method, the sampling points are merged by using the distance between the sampling points, and smooth processing of the sampling points is realized, so that when the break point of the hand-drawn line is determined based on the curvature of the target point, misjudgment of the break point caused by large curvature f
