[0002] In the discipline of mathematics, mathematical formulas are an important part of academic literature. At present, MathType and LaTex are mainly used to input mathematical formulas. However, with the further increase in the demand for digitization of documents, the first two methods face a lot of complexity. When editing mathematical formulas, it is difficult to edit and the efficiency is low

[0003] Online handwritten mathematical formula recognition can provide users with a mathematical formula entry method similar to writing on paper, but the complex structure of mathematical formulas greatly increases the difficulty of computer recognition, and the inaccuracy of handwritten input devices, writing style and speed , the ambiguity of mathematical symbols, and the variability of structures, etc., further increase the difficulty of recognizing and editing handwritten mathematical formulas

[0004] Moreover, in the existing online handwritten mathematical formula recognition process, the problem of misrecognition of characters often occurs, and the problem of misrecognition of characters will be superimposed on the analysis of the entire mathematical formula, thereby affecting the final recognition result of the mathematical formula , resulting in inaccurate mathematical formulas for recognizing handwriting
