Embodiment 1

[0017] Please refer to figure 1 , is a flow chart of a method for normatively judging handover and separation of strokes of handwritten Chinese characters according to an embodiment of the present invention, including the following steps.

[0018] Step 101. Obtain strokes of handwritten Chinese characters.

[0019] The above-mentioned method for obtaining the strokes of handwritten Chinese characters can be that the user writes on the touch screen, and the touch screen converts the touch pressure into pixels, and uses the pixels as the strokes of handwritten Chinese characters; The font on the white paper is converted into pixels, and the pixels are used as handwritten Chinese character strokes. In this embodiment, in order to facilitate the calculation of vector cross products, a Cartesian coordinate system can be established, and each obtained pixel point has its own coordinates.

[0020] Step 102. Determine stroke segments of handwritten Chinese characters. Determine whe...

Embodiment 2

[0038] Please refer to figure 2 , is a schematic diagram of a device for judging the normativeness of the handover and separation of strokes of handwritten Chinese characters according to an embodiment of the present invention. The normative judging device 200 of handwritten Chinese character stroke transfer in this embodiment includes:

[0039] Handwritten Chinese character stroke obtaining unit 201, for obtaining the stroke of handwritten Chinese character;

[0040] A stroke determining unit 202 is used to judge whether the stroke has an inflection point, if so, break the stroke at the inflection point and divide it into multiple stroke segments, otherwise, use one stroke as a stroke;

[0041] handwritten Chinese character handover and separation judging unit 203, used for judging the handover and separation relationship between the stroke segments of each stroke of handwritten Chinese characters and the stroke segments of other strokes;

[0042] To determine the transfer...

Abstract

The invention relates to the technical field for judging the regularity of hand-written Chinese characters, in particular to a method and a device for judging the regularity of cross, contact and separation in the strokes of hand-written Chinese characters. The method for judging the regularity comprises: acquiring the strokes of hand-written Chinese characters; judging whether turning point exists in the stroke; if turning point exists, breaking the stroke at the turning point, so as to divide the stroke into a plurality of sections; if turning point does not exist, taking the stroke as a writing section; judging the relation of cross, contact and separation between the writing section of each stroke and other strokes in hand-written Chinese characters; comparing the relation of cross, contact and separation between hand-written strokes of Chinese characters and the standard strokes of Chinese characters; if the two are identical with each other, the hand-written Chinese characters are judged as regular; if the two are not identical with each other, the hand-written Chinese characters are judged as irregular; by comparing the relation of cross, contact and separation between the writing section of hand-written strokes of Chinese characters and the standard writing section of strokes of Chinese characters, the invention can overcome the defects of manual review and realize thereal-time appraisal on the regularity of written Chinese characters. Therefore, the invention has the advantages of objective and all-round appraisal as well as low management cost.

Description

technical field [0001] The invention relates to the technical field of normative judgment of handwritten Chinese characters, in particular to a method and device for judging the normativeness of stroke handover and separation of handwritten Chinese characters. Background technique [0002] With the advancement of informatization, Chinese character writing is increasingly replaced by keyboard input, and the Chinese character writing ability of young people is declining. This has become a social problem that cannot be ignored. [0003] Chinese character writing assessment is an effective measure to promote the improvement of Chinese character writing ability. A key issue in this assessment is how to realize the standardization of handwritten Chinese character handover and separation. For example, for the word "工", if the vertical stroke exceeds the upper horizontal stroke, that is, the vertical stroke and the upper horizontal stroke intersect, it will become "soil". If the ver...
