Embodiment 1
[0046] see figure 1 As shown, Embodiment 1 of the Chinese character writing font recognition method provided in the embodiment of the present invention may include the following steps:
[0047] Step 101: Store standard stroke data of standard Chinese characters in advance, and the standard stroke data includes the coordinates of the points that make up the standard strokes.
[0048] 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 stroke order code is (1), and the most strokes are "Cuan" of 30 strokes, and the stroke order code is (321125125151145123412341344334). ...
Embodiment 2
[0074] see figure 2 As shown, Embodiment 2 of the Chinese character writing font recognition method provided in the embodiment of the present invention may include the following steps:
[0075] Step 201: Save standard stroke data of standard Chinese characters, and unify the points of each standard stroke.
[0076] Step 202: Collect and obtain real-time stroke data of real-time Chinese characters, and unify the dots of each real-time stroke. For example, by adding or deleting points, each standard stroke and each real-time stroke are composed of m points.
[0077] Step 203: One-to-one correspondence between standard strokes and real-time strokes. Since Chinese characters have a unique stroke order code, the first real-time stroke of the real-time Chinese character is corresponding to the first standard stroke of the standard Chinese character, and so on, the real-time strokes in the real-time Chinese character and the standard strokes in the standard Chinese character can b...

Abstract
The invention discloses a Chinese character writing font identification method and a Chinese character writing font identification device which are used for identifying the font of a Chinese character. The method comprises the following steps: storing standard stroke data of a standard Chinese character, wherein the standard stroke data includes the coordinates of the points constituting standard strokes; acquiring first real-time stroke data of a real-time Chinese character input by a user in a stroke way, wherein the first real-time stroke data includes the coordinates of the points constituting real-time strokes; calculating the center of gravity of the standard Chinese character according to the standard stroke data, and calculating the center of gravity of the real-time Chinese character according to the first real-time stroke data; shifting the real-time Chinese character by the difference between the center of gravity of the real-time Chinese character and the center of gravity of the standard Chinese character, and acquiring second real-time stroke data of the shifted real-time Chinese character, wherein the second real-time stroke data includes the coordinates of the points constituting the shifted real-time strokes; and calculating the distance between each shifted real-time stroke and the corresponding standard stroke according to the coordinates of the points constituting the shifted real-time stroke and the coordinates of the points constituting the standard stroke.
Description
technical field [0001] The invention relates to the field of computers, in particular to a method and device for recognizing written Chinese characters. 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, to check Characters printed on paper determine their shape by detecting dark and light patterns, and then use character recognition methods to translate the shape into computer text. [0003] In the above application, the recognition of characters is based on the unit of characters, and the recognition target 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 the shape of...
