Method and apparatus for judging stroke position standard of handwritten Chinese character

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...

AI Technical Summary

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, and then write the lower horizontal stroke , if the user first writes the horizontal strokes below, and then writes the horizontal strokes above, the existing technology still thinks that the writing is correct, and it is impossible to judge the standardization of the stroke positions of handwritten Chinese characters
