Problems solved by technology

[0003] It can be seen from the above prior art that it uses the similarity of the handwritten sequence set of the overall handwritten Chinese character as the criterion for identifying Chinese characters, such as the Chinese character "two", the correct stroke order should be to write the upper horizontal stroke first,

Embodiment 1

[0023] Please refer to figure 1 , is a flowchart of a method for judging the standardization of stroke positions of handwritten Chinese characters according to an embodiment of the present invention. The method for judging the normality of stroke positions of handwritten Chinese characters in this embodiment includes the following steps.

[0024] 101. Acquire the strokes of handwritten Chinese characters, and calculate the number n of strokes of handwritten Chinese characters; default k=2.

[0025] The above-mentioned method for obtaining the strokes of handwritten Chinese characters can be as follows: the user writes on a touch screen or a tablet, and the touch screen or tablet converts the touch pressure into pixels, and uses the pixels as the strokes of handwritten Chinese characters, or directly obtains them with a digital pen Writing strokes; also can write on blank paper for the user, scan the font on this blank paper, convert to pixel point, use this pixel point as han...

Embodiment 2

[0050] Please refer to Figure 4 , is a schematic diagram of a device for judging the normality of stroke positions of handwritten Chinese characters according to an embodiment of the present invention. The judging device of the handwritten Chinese character stroke position normativeness of the present embodiment comprises:

[0051] Handwritten Chinese character stroke obtaining unit 202, is used for obtaining the stroke of handwritten Chinese character, calculates the stroke number n of handwritten Chinese character;

[0052] A parameter preset unit 201, configured to preset k=2;

[0053] Handwritten Chinese character vector acquisition unit 203 is used to obtain the vector of the starting point of the kth stroke of the handwritten Chinese character according to the stroke order direction to the start point of the (k-1) stroke according to the stroke order direction;

[0054] The standard Chinese character vector acquisition unit 204 is used to obtain the vector of the star...

Abstract

The invention relates to a technology for judging the normalization of handwritten Chinese character stroke position, in particular to a method and a device for judging the normalization of the handwritten Chinese character stroke position. The method for judging the normalization of the handwritten Chinese character stroke position comprises the steps of obtaining the strokes of handwritten Chinese characters, obtaining a vector that the starting point of the No. k stroke according to the direction of the stroke order of a handwritten Chinese character points to the starting point of the No. (k-1) stroke according to the direction of the stroke order; obtaining the vector that the starting point of the No. k stroke according to the direction of the stroke order of a Chinese character of a standard-word-base corresponding to the handwritten Chinese character points to the starting point of the No. (k-1) stroke according to the direction of the stroke order, calculating an included angle theta between the vector of the handwritten Chinese character stroke and the vector of the Chinese character stroke of the standard-word-base, and judging whether the included angle theta is within a preset error range delta theta, if so, the stroke position of the handwritten Chinese character is standard, otherwise, the stroke position of the handwritten Chinese character is non-standard. The technical proposal of the invention can identify the situation of incorrect writing stroke order of the handwritten Chinese characters with the same strokes and stroke features.

Description

technical field [0001] The invention relates to a technology for judging the normality of stroke positions of handwritten Chinese characters, in particular to a method and device for judging the normality of stroke positions of handwritten Chinese characters. Background technique [0002] The existing handwriting recognition technology is to record the coordinates of the pixel points according to the handwriting direction (chronological order) and the vector value of the handwriting direction while the user is writing, and divide them into different sequences according to strokes (also called strokes) Set, process these records to standardize each pixel point in each sequence set; then, compare the handwritten font sequence set with the standard font sequence set in the standard font library, take the Chinese character with the highest similarity, and return it as the recognition result to user. [0003] It can be seen from the above prior art that it uses the similarity of...
