Method and device for judging standardization of writing Chinese characters

Abstract

The invention relates to the field of computer data processing technology, in particular to a method for judging the standardization of writing Chinese characters. The method comprises six parts of: collecting and recording the stroke tracks of writing Chinese characters; mapping the tracks of writing Chinese characters into a scale coordinate system with a size same as that of a template Chinese character; extracting writing track key points by adopting a Douglas-Peucker algorithm; obtaining the feature vectors of all the strokes according to the obtained key points; matching the stroke features: dynamically planning and matching each stroke of writing the Chinese character with a corresponding stroke of a corresponding Chinese character in a Chinese character standard template feature library; and comprehensively judging the standardization of writing Chinese characters by adopting a decision tree method. The invention can overcome the negative influences caused by subjectivity and the fatigue caused by artificially judging Chinese characters, and can judge the standardization of writing Chinese characters.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for evaluating the normativeness of written Chinese characters. Background technique [0002] In the fields of Chinese character application proficiency testing and Chinese character application teaching, how to effectively judge the standardization of written Chinese characters is a relatively new topic. The method currently used is mainly evaluated by people (teachers). On the one hand, this method is highly subjective, and people who write the same Chinese characters with different characters may give quite different judgments; on the other hand, this method Boring and repetitive work is easy to make people tired. The same Chinese character is judged by the same person in different time periods, and different judgment results may be given.

AI Technical Summary

Problems solved by technology

However, since this patent uses the center of gravity of strokes and parts to evaluate the layout of strokes and parts, it is obvious that any rotation around the center of gravity of strokes or parts will not change the length and size of strokes or parts. The method of this patent will have no effect on the evaluation of strokes and components after rotating at any angle, and the strokes of Chinese characters are directional, which obviously does not conform to the common sense of writing Chinese characters. Therefore, only the center of gravity is used as an index to evaluate the strokes of Chinese characters It is lacking in the evaluation of components and components, and other constraints need to be added to make a more effective evaluation of written Chinese characters

[0004] The Chinese invention patent "A method for evaluating the quality of Chinese character writing based on confidence" (publication number CN101630362A) proposes a method for evaluating the quality of Chinese character writing based on confidence. The patent uses a modified quadratic judgment function to calculate the distance of candidate characters. Then calculate the confidence level according to the distance of the candidate characters and evaluate the writing quality of Chinese characters. Since the evaluation standard of this patent depends on the selection of training samples (that is, written Chinese characters), if the training samples are neatly written, then the neatly written Chinese characters have a higher Good evaluation; obviously, even neatly written Chinese characters can be good or bad, and this method is not able to evaluate such cases
