Problems solved by technology

[0003] In the above-mentioned applications, the recognition of characters is based on the unit of characters, and the recognition goal is to determine what characters are input. However, in some fields, the writing process of Chinese characters also needs to be paid attention to, such as Chinese character fonts, stroke directions, and strokes. Whether the order, stroke position, etc. are correct, but in the existing technology, there is no technology to identify the writing process

Embodiment 1

[0054] Based on the above ideas, see figure 1 As shown, Embodiment 1 of the Chinese character writing recognition method provided in the embodiment of the present invention may include the following steps:

[0055] Step 101: Store the standard stroke data of standard Chinese characters in advance, the standard stroke data of each standard Chinese character includes the order information of each standard stroke in the standard Chinese character and the direction position information of each standard stroke.

[0056] Chinese characters are composed of strokes, which can be divided into five types: horizontal, vertical, left, dotted, and folded. They can be coded with numbers 12345, so that each Chinese character has a unique stroke order code, that is, the order information of each stroke, which also includes Unique stroke count. For example, there are 6763 Chinese characters in the Chinese character encoding standard GB2312, and the least stroke is "one" of 1 stroke, and the s...

Embodiment 2

[0083] see figure 2 As shown, it is the second embodiment of the Chinese character writing recognition method provided in the embodiment of the present invention, which may include the following steps:

[0084] Step 201: standard Chinese character data collection. The standard Chinese characters written by famous calligraphers are scanned and collected to form a standardized font format TTF (True Type Font) or OTF (Open Type Font). TTF or OTF fonts are standard font formats that can be used by various operating systems. For fonts Outline the result of the description.

[0085] Step 202: Characterization processing of standard stroke data. Characterize the TTF font library to form standard stroke data of standard Chinese characters.

[0086] Step 203: The font attribute parameters of standard Chinese characters are added. Each Chinese character also has its glyph attributes: such as stroke rectangle position, glyph structure information, component rectangle, etc.

Abstract

The invention discloses a recognition method and device for Chinese character writing. The recognition method and device are used for recognizing a Chinese character writing process. The recognition method comprises the steps that the standard stoke data of standard Chinese characters are pre-stored, wherein the standard stoke data include the information of the sequence of the standard strokes of the standard Chinese characters and the information of the directions and positions of the standard strokes; the real-time stoke data of a real-time Chinese character input by a user are collected, wherein the real-time Chinese character is the same as a specific Chinese character, the specific Chinese character is one of the standard Chinese characters, and the real-time stoke data include the information of the sequence of the real-time strokes of the real-time Chinese character and the information of the directions and positions of the real-time strokes; the corresponding relation between the standard stokes of the specific Chinese character and the real-time stokes of the real-time Chinese character is obtained according to the information of the directions and the positions of the real-time strokes and the information of the directions and the positions of the standard stokes of the specific Chinese character; the standard stoke data of the specific Chinese character are compared with the real-time stoke data of the real-time Chinese character according to the corresponding relation, and a recognition result of the correctness of the real-time Chinese character writing process is obtained.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a Chinese character writing recognition method and device. Background technique [0002] Chinese characters are widely used in people's daily life and work. In the prior art, the technology of using computers to automatically recognize characters is relatively mature. For example, OCR (Optical Character Recognition, Optical Character Recognition) is to use electronic equipment, such as scanners or digital cameras. , check the characters printed on the paper, determine its shape by detecting dark and light patterns, and then use character recognition methods to translate the shape into computer text. [0003] In the above-mentioned applications, the recognition of characters is based on the unit of characters, and the recognition goal is to determine what characters are input. However, in some fields, the writing process of Chinese characters also needs to be paid attention to, ...
