Embodiment 1

[0022] Please refer to FIG. 1 , which is a flowchart of a method for evaluating the normative structure of written Chinese characters according to Embodiment 1 of the present invention. The method for writing the normative evaluation of Chinese character structure in this embodiment includes the following steps.

[0023] 101. Acquire the pixel points of the trajectory of the written Chinese characters, and use the pixels to determine the bounding box of the written Chinese characters.

[0024] There are many ways to obtain the pixel points of writing Chinese characters. For example, you can write Chinese characters directly on the touch screen or handwriting board, so as to obtain the pixel points of writing Chinese characters according to the captured writing track, or you can write Chinese characters on paper and then scan them. , which is converted into pixels for writing Chinese characters.

[0025] The standard evaluation method for the structure of written Chinese chara...

Embodiment 2

[0062] Please refer to FIG. 5 , which is a schematic diagram of a device for evaluating the normative structure of written Chinese characters according to Embodiment 2 of the present invention. The device of this embodiment includes:

[0063] Writing trajectory acquisition unit 501 is used to obtain the writing stroke trajectory of writing Chinese characters, and converts the trajectory into pixels; it can be a device that can capture the writing trajectory such as a tablet, a touch screen, or a light pen;

[0064] The pixel point acquisition unit 502 is used to obtain the pixel point of writing Chinese characters from the writing track acquisition unit 501;

[0065] Constraint frame determination unit 503, used to determine the constraint frame of writing Chinese characters by using the pixels acquired by pixel point acquisition unit 502;

[0066] The lateral symmetry parameter difference obtaining unit 504 is used to obtain the lateral midline of the constrained frame deter...

Abstract

The invention discloses a method for structural normative appraisement of writing Chinese characters, which comprises that: a horizontal symmetric parameter difference value, a longitudinal symmetric parameter difference value, a compact parameter difference value and a distributed vector parameter difference value are obtained, and the writing Chinese character is made a structural normative appraisement by taking advantage of the four difference values according to a learning mechanism of a supervision classification machine. Correspondingly, the invention further discloses a device for structural normative appraisement of writing Chinese characters. The technical proposal embodies three characteristics of the symmetry, the compactness and the uniformity of the Chinese character structure, can accurately appraise the structural normative of the writing Chinese character, overcomes the disadvantage of the subjectivity of manual read overmarginalia, and has the advantages of objective and comprehensive appraisement, low management cost and high working efficiency.

Description

technical field [0001] The invention relates to the technical field of normative evaluation of written Chinese character structure, in particular to a method and device for normative evaluation of written Chinese character structure. 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. The key issue of this assessment is how to realize the structural normative evaluation of written Chinese characters. For this evaluation, the method of subjective review by teachers is now used. However, there is a lot of subjectivity in the method of manual review, and different teachers may have different evaluations for the same written Chines...
