[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 character 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.

[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 the 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 embod...

[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 invention discloses a written character recognizing method and a written character recognizing device. The written character recognizing method includes acquiring written character information of a user; finding out a corresponding alternative character set of the written character information; analyzing match degree between the written character information and each character in the alternative character set; recognizing the written character information as corresponding characters according to the match degree. According to the technical scheme, the written character recognizing method has the advantages that when the method is used for written character recognizing, a written character of the user is matched with a plurality of similar-form characters to confirm the character to be written by the user, so that similar-form character recognizing errors during written character recognizing are avoided, and user's written character recognizing accuracy rate is increased.

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...
