Abstract

The embodiment of the invention provides a formula identification method and device and the device for formula identification. The method comprises the following steps: acquiring track points input in real time, and preprocessing the track points to obtain a track point sequence; inputting the track point sequence into a pre-trained recognition model, and performing feature extraction and encoding on the track point sequence through an encoder in the recognition model to obtain a high-dimensional feature vector; and performing information identification and decoding on the high-dimensional feature vector through a decoder in the identification model to obtain a formula identification result. According to the embodiment of the invention, when the user writes the formula, the track points input in real time are preprocessed, and the preprocessed track point series is identified based on the pre-trained identification model, so that the accuracy of formula identification is improved.

Description

technical field [0001] The present invention relates to the technical field of information recognition, in particular to a method and device for formula recognition and a device for formula recognition. Background technique [0002] Mathematical formulas are very common in textbooks, scientific papers and other documents, but the operation process for users to input formulas into electronic documents is relatively cumbersome. With the development of interactive technology between handwriting and electronic devices, users can directly write formulas on electronic devices by handwriting, [0003] However, due to the complex spatial relationship of characters in mathematics and other formulas, the existing formula recognition methods usually have garbled characters or unrecognizable situations, resulting in low recognition accuracy and poor recognition effect. Contents of the invention [0004] Embodiments of the present invention provide a method and device for formula reco...
