Kinematics-based online handwriting determination method, system and equipment and medium

The invention discloses an online handwriting determination method based on kinematics. The method comprises the following steps: acquiring an electronic signature handwriting feature data sequence, segmenting a signature track, calculating speed pulse components and continuous components in adjacent segments of the signature track, acquiring rhythm features of signature strokes, and determining the overall trend and local change of signature writing speed; and acquiring an elliptic arc parameter of the signature track according to the static contour, and determining track layout characteristics of the signature strokes. Based on the human body writing movement principle, the method gives consideration to the writing track and speed, does not depend on a large amount of training data, obtains accurate electronic signature track parameters, and provides accurate basic data information for handwriting identification, handwriting compression, handwriting display and the like. 本申请公开一种基于运动学的在线笔迹确定方法，获取电子签名笔迹特征数据序列
