Abstract
本公开提供一种手写体识别方法及装置，该手写体识别方法包括：检测用户在手写屏上的手写轨迹对应的多个轨迹点的信息，多个轨迹点包括起始轨迹点和当前轨迹点；若当前轨迹点为终止轨迹点，将起始轨迹点和终止轨迹点期间的轨迹点作为待识别轨迹点，当前轨迹点的抬笔时刻之后的预设时长内未检测到新的轨迹点则为终止轨迹点，起始轨迹点为上一次输入给文本识别模型的最后一个轨迹点的下一个轨迹点，或者，手写屏的第一个轨迹点；采用文本识别模型对待识别轨迹点的信息进行识别，得到文本识别结果；以印刷体形式显示文本识别结果。本公开实施例中，实时显示手写轨迹的文本识别结果，从而方便用户实时查看和纠正文本识别结果，能够有效提高识别率。
