Problems solved by technology

[0002] In chemistry teaching, learning as a participant is more effective than passive learning. In the traditional chemistry teaching process, when the writer writes chemical equations, the written chemical equations cannot be correctly recognized and processed, which directly affects the effectiveness and accuracy of chemistry teaching. At the same time, in the process of chemistry teaching in middle schools, the problem of inaccurate balance of general and special reactions is prone to occur, which leads to the need to spend a lot of time to correct the inaccurate balance in the chemistry teaching process, and the efficiency and effect of chemistry teaching are affected.

Abstract

The invention discloses a handwritten chemical formula recognition and balancing method, comprising the following steps: providing a handwritten handwriting point sequence of a chemical equation, running a segmentation algorithm on the handwritten handwriting point sequence, obtaining pictures of independent characters, and using CNN and a dictionary to optimize the operation The recognition algorithm obtains the character string representing the chemical equation, runs the balance algorithm, obtains the correct chemical equation balance result and displays it in a standardized format; the method of the present invention performs handwritten chemical equation recognition based on CNN and dictionary optimization, and is applicable to non-connected Writing with a pen solves the problem of identifying chemical equations on handwritten devices. Through the method of balancing chemical equations based on conservation of elements and conservation of electrons, it solves the problem of balancing general and special reactions in middle schools. The comprehensive use of both can effectively improve chemistry teaching. Efficiency, reducing the error probability of chemical equations in the process of balancing, and improving the accuracy of balancing.

Description

Technical field [0001] The present invention relates to the field of image recognition, and more particularly to a handwritten chemical formula identification and a flat method. Background technique [0002] In the chemistry teaching, the study as a participant is more than passive learning. In the traditional chemical teaching process, the writing of the chemical equation will not be correctly identified correctly, directly affecting the effect and accurate of chemical teaching. Sex, in the chemical teaching process within the scope of the secondary school, it is prone to the general and special reactions, which leads to a lot of time to consume a lot of time to correct the formation of fault, and the efficiency and effect of chemical teaching are affected. Based on the existing CNN image recognition technology, the present invention proposes a handwritten chemical equation recognition method to add a dictionary to solve the shortcomings in existing chemical equation handwriting...
