Example

[0077] see figure 1 , a flow chart of the first embodiment of the method for character writing standardization evaluation provided by the present invention, the method includes:

[0078] S101. Collect and record stroke trajectories of written characters.

[0079] In the method provided by the present invention, the user can pre-select the Chinese character that the user wants to practice currently, and write the corresponding character in the preset writing area, so as to establish the corresponding relationship between the character to be evaluated written by the user and the standard character. Of course, the selection step may not be included, and the writing area may be directly provided to collect stroke trajectories of characters written by the user. The system records the stroke trajectory of the collected characters as a series of two-dimensional coordinate point columns P i (x i ,y i ) and mark the stroke start and end marks.

Abstract

The present invention relates to the field of mode recognition, and particularly relates to a method and apparatus for assessing standard fulfillment of character writing. The method comprises: collecting and recording the stroke trace generated in writing characters; extracting trace dynamic characteristics of the stroke trace; matching the extracted trace dynamic characteristics with a preset character model corresponding to the written character, searching for an optical match path, and obtaining a similarity score corresponding to the optical match path, wherein the character model is used to simulate the character writing dynamic trace in at least one common writing sequence; and judging whether the similarity score is greater than a first threshold, if true, determining that the written character fulfills the standard. The method provided in embodiments of the present invention effectively solves the problem that the standard fulfillment is low due to an inconsistent writing stroke sequence in the prior art, and improves rationality, subjectivity, and accuracy of writing standard fulfillment.

Description

technical field [0001] The invention relates to the field of pattern recognition, in particular to a method and a device for evaluating standardization of character writing. Background technique [0002] With the development of information interaction, computer-assisted teaching has been widely used. For example, in terms of Chinese teaching, computer-assisted teaching provides applications such as Chinese character evolution, pinyin demonstration, and dynamic demonstration of Chinese character writing. However, it is less involved in the evaluation of users' Chinese character writing standardization. A well-written Chinese character usually requires standard strokes and stroke order, and the overall structure of the character is compact and meets the requirements of aesthetics. Due to the large number of Chinese characters, the normative evaluation of Chinese characters is more complicated, involving image processing, pattern recognition and other technologies. Therefore, ...
