[0067] Combine below figure 1 , figure 2 The flow of the method for recognizing written characters in the first embodiment of the present invention will be described, including the following steps:

[0068] Step S101 , acquiring user's handwriting information.

[0069] In the first embodiment, the written word information includes stroke information written by the user, stroke order information, text frame structure information, and the like.

[0070] Step S102, find out a set of candidate characters corresponding to the written word information.

[0071] In the first embodiment, it is necessary to establish a near-character database in advance, and the near-character database stores the related information of each character. By querying the near-character database, the corresponding information of the written characters can be obtained. A set of alternative texts, the characters in the set of alternative texts have similar glyphs.

[0072] In this embodiment, after obtai...

[0083] The second embodiment On the basis of the first embodiment, another embodiment is provided in which the written word information is recognized as a corresponding character according to the degree of matching of similar characters. The following is combined image 3 The description of the second embodiment of the present invention includes the following steps.

[0084] Step S201 , acquiring user's handwriting information.

[0085] In the second embodiment, for the specific implementation manner of this step, reference may be made to the description in the first embodiment above, and details will be repeated here.

[0086] Step S202, identifying the written word information as a first candidate character.

[0087] In the second embodiment, the written word information can be recognized as a corresponding character according to any existing method for recognizing written characters, and the recognized character is regarded as the first candidate character in this embodime...

[0108] On the basis of the above-mentioned first and second embodiments, the third embodiment has made further improvements, especially when the matching degree of the first candidate characters and the written word information is the same as that of the first candidate characters When the difference between the matching degree of itself and the written word information is small, the recognition accuracy can be further improved.

[0109] Combine below Figure 5 , the method for recognizing written characters according to the third embodiment of the present invention is described, including the following steps:

[0110] Step S301, acquiring the user's handwriting information.

[0111] Step S302, identifying the written character information as the first candidate character.

[0112] Step S303, searching the preset near-shaped character database, is there any near-shaped character associated with the first candidate character? If so, execute the next step, otherwise, execute ...

Abstract

The method and device for recognizing written characters disclosed in the present invention, the method includes: obtaining the user's written word information; finding out a set of candidate characters corresponding to the written character information; analyzing the written character information and the candidate characters. The matching degree of each character in the character set; according to the matching degree, the written word information is identified as the corresponding character. Through the technical scheme of the present invention, the user's written characters can be matched with several similar-shaped characters with similar shapes when recognizing written characters, and the Chinese characters to be written by the user can be determined from them, which solves the problem of similar shapes when recognizing written characters. Word recognition errors, improve the recognition accuracy of the user's handwritten words.

Description

technical field [0001] The invention relates to the technical field of handwriting recognition, in particular to a method and device for handwriting recognition. Background technique [0002] Existing point-reading machines and other products include the function of practicing calligraphy, and provide a free practice mode. Users can write any Chinese character. Comprehensive evaluation of writing, and output of writing evaluation results to guide users' writing practice. [0003] However, the existing technology has the following defects in the recognition of written characters: when the Chinese characters written by the user have similar characters, the system may misjudgment, and the problem of recognition errors of similar characters occurs. The writing evaluation of the user is also wrong; for example, the Chinese character that the user wants to write is "earth", the system may recognize it as "shi", and then evaluate the user's writing according to the writing standar...
