Abstract

The invention provides a formula identification method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a to-be-recognized image containing a formula; identifying the tree structure of the formula based on a decoder network to obtain characters included in the formula, wherein nodes included in the tree structure correspond to the characters included in the formula; and based on the relation branches of the decoder network, determining the spatial position relation between the nodes in the tree structure, wherein the spatial position relation comprises the position relation between a father node and a corresponding child node under the condition that the current known node in the tree structure serves as the father node. Therefore, the precision of formula identification can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of artificial intelligence, and in particular to a formula recognition method, device, electronic equipment and storage medium. Background technique [0002] With the popularity of online teaching, there are more and more applications for formula recognition. In the formula recognition scene, most users use mobile phones, tablet computers and other electronic devices to take pictures of the formulas to be recognized to obtain images to be recognized. After the application program that can perform formula recognition acquires the image to be recognized, it uses a pattern recognition algorithm to recognize the formula in the image. However, the computational complexity of the existing pattern recognition algorithm is high, and the recognition accuracy is low, so it needs to be improved. Contents of the invention [0003] The disclosure provides a formula recognition method, device, electronic equi...
